Week 9: Foods Fit for Living - the List

This site began with a simple, personal goal: eat well.

Doing so proved more difficult than we thought it would be, requiring knowledge beyond what is readily offered by both the food industry and the US government. A constant negotiation between Washington, DC elected officials and lobbyists seesaws between human and economic health. Food labels - the only tangible outcome of this perpetual tug-of-war, are are only moderately helpful, focusing on calories, fats, sugars, sodium and fiber. While these are important metrics, they are hardly comprehensive. More key nutritional data are missing on labels than is included: that of all 14 vitamins and 16 minerals, as well as detailed information related to the make-up of a food's fatty acids, proteins and carbohydrates. The differences within each category are essential to whether something is good for you, or bad. Furthermore, when we eat out, whether at a pizza joint or a fine restaurant, it's impossible to determine whether our body's needs are being met. Instead, we are forced to rely on instinct and rules of thumb: 'eat some salad', 'skip the cheesecake', 'leave some fries on the plate'...

In establishing FFFL, we had a few fundamental questions in mind: 

  1. What foods are healthiest, and why?

  2. What are the best sources of each nutrient, and in what form?

  3. What do we need to consume in order to meet 100% of the 'recommended daily intake' of all nutrients? Is it even possible to do so in a single day, from real foods? And what would that menu look like?

  4. Once we have answers, can we create a single chart of the world's healthiest foods with comprehensive nutritional data, as a reference for people?

The answer to the last question is yes - and we've included it here, for you. Comprised of the 81 foods we consider both healthiest and widely available, they run the gamut between single-nutrient dynamos and pan-nutrient superstars. 

You can download a high-resolution version of the chart here. Print it. Study it. Keep it as a reference in your kitchen, with your cookbooks or taped on the inside of a cabinet door. We do. Serving sizes are included both in volume and in weight, to help quantify things that don't measure easily, like greens. To that end, a kitchen scale is a small investment that can help you to develop an instinct for portion size and remove the mystery. Nutrient levels below 7% of daily recommended intake have been omitted, to focus instead on significant contributors to dietary health. Percentages are based on a 2,000-calorie diet for an 'average' person. Lastly, nutrient levels vary - sometimes dramatically - based on a food's freshness, preparation, and growing methods. We always recommend you buy the freshest food possible, grown in the most natural way available, and eat it in its least altered state. 

What follows is a selective list of foods/groups that everyone should include regularly in their diets. They include just some of the foods from our comprehensive chart, to dive a little deeper into what makes them so good for us. They are powerhouses across a variety of key nutrients; are readily available, most anywhere; and will, together, provide you with the ingredients for long-term dietary health. Beyond these, remember the well-worn adages: eat the rainbow (all colors); vary your intake (for broader nutritional health); process (i.e.: cook/blend) whole foods minimally, while avoiding all things laboratory-made; eat at peak ripeness (local beats transported); and prepare it yourself, to the greatest degree practical (so that you know exactly what you are eating).

Avocados 

Avocados deliver nature's highest dose of monounsaturated fats, which help reduce levels of LDL (bad) cholesterol, thus lowering your risk of heart disease and stroke. After avocados, the foods next highest in monounsaturated fats are olives and olive oil, cashews, salmon and almonds.

The fats in avocados (and the other foods listed above) are key to promoting the body's absorption of fat-soluble vitamins A, D, E and K. In the case of vitamin A, avocados increase the absorption of carotenoids in low-fat foods like sweet potatoes, carrots, spinach and kale by 200-600%. They also improve the conversion from beta-carotene to vitamin A. Carotenoids (like beta-carotene, lycopene and lutein, to name a few) are key to eye health (the reduction of retina degeneration) and positively influence a wide spectrum of systems, from male reproductive health to liver, prostate, colon, breast and lung health.

Surpassed only by beans and barley, one avocado serves up 40% of your DRI of fiber - 63-82% of which is insoluble, in the California and Florida varieties, respectively. Soluble fiber lowers blood cholesterol and glucose levels by slowing the absorption of sugars. Soluble fiber also helps you feel full longer, reducing your urge to overeat and thereby aiding in weight loss and reducing rates of obesity. Insoluble fiber, on the other hand, remains intact through your lower intestine, where it pushes waste, including toxins, out of your system, keeping you 'regular'. 

Beans

Yes - I just lumped all beans together. While there are over 40,000 types of bean, fewer than a dozen make up the overwhelming majority of those broadly cultivated and consumed. Most of these are included on our list: pinto, garbanzo (chickpeas), black, kidney, navy, lima and soy, as well as lentils and green peas. While nutrient densities vary, all beans follow a similar profile with respect to being a significant source of fifteen vitamins and minerals, with occasional standouts in any particular category. 

Beans are the plant world's reigning monarchs in protein content, packing roughly 30-60% of your daily recommended intake (DRI). Queen among queens is the soybean, with nearly 29g (57%) per cup. All beans contain at least 30% of your DRI. If you are vegetarian or simply avoid animal proteins due to (largely well-founded) health concerns, then the bean family, which includes lentils and green peas, are a phenomenal resource.

Folate is a broad group of B-vitamin nutrients, of which folic acid - the only form found in fortified foods - is just one. Women in particular are familiar with the need for adequate folate intake, as it is a key nutrient in female reproductive health, insofar as reducing the risk of neural tube defects in pregnant women. Beyond this well-published benefit, folate is a key contributor to human neurological health, maintenance of a healthy colon, and - when combined with zinc sulfate, has been shown to augment male sperm count by 74%, along with their motility and morphology rates. While folate (from the latin root word for 'leaf') is often associated with dark, leafy greens, beans are the single greatest source of this nutrient, with lentils (90% of DRI) leading the charge, and pinto and garbanzo beans (aka chickpeas) comprising a close second.

Fiber. Yet again, in this category, beans occupy the top nine spots in the world's best source of dietary fiber. From navy beans (76% DRI) to kidney beans (45% DRI), fiber is the digestive system's ally, providing all the benefits to general health that we've already outlined just above.

Cruciferous vegetables

While we covered this category of wonder foods in detail in Week 8's post, any list would be incomplete without them. The group is varied, and includes such seemingly different vegetables as broccoli, Brussels sprouts, cabbage, cauliflower, collard greens, kale, kohlrabi, mustard, rutabaga, turnips, bok choy, and Chinese cabbage, in addition to arugula, horse radish, radish, wasabi, and watercress. Part of their key value as a group is their glucosinates, which offer several benefits, including reduction of lung and colorectal cancer risk, and fortification of the gut's lining - keeping toxins inside of it so that the digestive system can purge them. Beyond glucosinates, crucifers are powerful anti-inflammatories. Chronic inflammation, as we reported in Week 3's post - and which is caused in great part by what we eat - can 'lead to environments that foster genomic lesions and tumor initiation' - i.e.: cancer, as summarized in a highly detailed 2006 entry in the Yale Journal of Biology and Medicine here. Put in plain English: cancer cells feed on inflamed tissue, while the reverse - a reduction in inflammation - starves the cancer cells of the nutrients that allow for their proliferation in our bodies. 

Individually, the nutrients in crucifers vary far more than they do in the bean family. Let's look at three individual all-stars in brief. These three vegetables are individually among the world's healthiest foods.

Broccoli is the plant world's best manager of corporeal inflammation, oxidative stress (which does damage to cells, pointedly DNA) and toxicity. Together, these three processes are interwoven, with an imbalance of one creating an imbalance or reduced ability to manage the others. Broccoli does two things: it manages the relationship between them, and it contains nutrients that are themselves anti-inflammatory, antioxidant and detoxifying. Although we cut inclusion of nutrients off at 7% DRI on the FFFL list, one cup of broccoli contains at least 5% of twenty-four separate vitamins and minerals, making it one of the most robust in the plant kingdom, including 240% of vitamin K, 135% of vitamin C - far more than an orange! - and nearly half of your folate. In addition, that serving provides 8% of your omega-3s, 21% of your fiber and 7% of your protein, to highlight just a few.

Brussels Sprouts top the list of glucosinate content among crucifers, besting even broccoli in this regard and making them an anti-cancer champion. Like broccoli, they are also great detoxifiers, anti-inflammatories and anti-oxidants. From a nutrient standpoint, Brussels sprouts contain twenty-one separate vitamins and minerals. Most of these track closely with those in broccoli. Brussels sprouts have the edge in also providing 10% of your iron, and 11% of your omega-3s. Beyond the percentages of your DRI (daily recommended intake) within each category, the specific make-up of glucosinates and anti-oxidants vary between crucifers, and so you will want to vary your intake and sources.

Arugula (called Rocket in the UK) has a bitterness that the Mediterranean farmers where it originates enjoyed, and which, like herbs, green tea and radishes, stimulates an entirely different digestive process than do other non-bitter foods. Those who advocate nutrient balance suggest we get adequate amounts of foods that contain all four basic tastes (leaving umami aside): sweet, salty, bitter, sour. Each one aids in a feeling of satiety, reducing the urge to overeat. Beyond this, bitter foods like arugula activate taste buds that simultaneously promote enzyme production and bile flow. These processes are key to digestion, which breaks down foods into nutrients the body can then use. Besides arugula's broad nutrient base - fourteen vitamins and minerals - these bitter greens are natural liver detoxifiers.

A last note on arugula (and other dark, leafy greens): beyond measuring vitamin and mineral content, an index of great value exists that analyzes content and density of the root nutrients behind the vitamins and minerals that contain them, since vitamin and mineral names are, frankly, just convenient labels for groups of organic compounds produced and consumed by plants and animals alike. The index is called the Aggregate Nutrient Density Index (ANDI), and measures phyto-chemicals like polyphenols, carotenoids, retinoids, glucosinates and chlorophylls, among others. Arugula scores sixth highest on the ANDI, behind other foods you may have intuitively expected: kale, collard greens, bok choy, spinach and Brussels sprouts. ANDI scores don't replace other measures of nutrition in any way. They do provide information about a growing area of scientific research into the relationship between phyto-chemicals and health. While broad conclusions are highly contested, a large number of researchers are beginning to connect high phyto-chemical content with lowered risks of cardiovascular disease, high blood pressure, cancers, diabetes and neuro-degeneration. An interesting resource for more information can be found here.

Spinach

Spinach is, gram per gram, the single most nutrient-dense food in the world. So much so that it almost feels like a 'gimme' to spend time discussing it here. But then again, if everyone knew what we do about nutrition, we wouldn't need sites like this to help connect people with real data from people who don't sell anything or have a vested interest in specific outcomes. So where to begin with this god among plants? Spinach is a good to excellent source of twenty-four distinct vitamins and minerals, with a single serving providing your entire DRI of vitamins A and K, the majority of your manganese and folate, and between one quarter and one third of your magnesium, iron, copper, vitamins B2 and B6, vitamin E, calcium, vitamin C and potassium. Like kale, spinach tops the list of bone health-promoting vitamin K, at nearly 1,000% of your DRI in a single serving. After nuts and beans (and soybeans' derivatives, tofu and tempeh), spinach is among the highest sources of plant-based protein, adding 11% of your DRI. Only green peas, at 15% (!) and oats, at 13%, rank higher. Lastly, spinach plays the same anti-inflammatory, anti-oxidant and detoxifying role as crucifers, keeping your systems healthy.

(Side note: the common green pea is a powerhouse on its own - an excellent source of fifteen vitamins and minerals, has significant protein, as we saw, and 30% of your daily fiber.)

Marine Foods

Salmon, sardines, scallops and shrimp - all in one alliterative breath. What do two fish, one mollusk and a crustacean have in common? Apart from being sea creatures, which matters from a health standpoint, they are perhaps the healthiest contributors to several essential nutrients that are almost entirely absent from the plant world. These include vitamins B12 and D, choline and selenium. B12 is essential to DNA production, brain and nervous system health. Luckily, it can also be stored for years in the body, unlike all other B vitamins. Vitamin D is key to bone health, increasing calcium in the bloodstream. Choline is central to production of phosphatidylcholine - a key structural building block of cells - keeping them elastic yet impermeable. And in addition to its anti-oxidant protection, selenium is responsible (with iodine) for strong thyroid function, turning T4 hormones into T3. In just 2 months of a low-selenium diet, thyroid function can begin to suffer. 

Thus, the inclusion of animal foods is key to ensuring adequate intake of all four key nutrients and avoiding deficiency and its attendant health risks. Salmon provides the second highest density of B12 (236%), the highest of D (128%), the fourth highest of selenium (78%), and reasonable choline (19%) - leading the list among healthy animal foods for that reason. Sardines top the list of B12 (338%), are second best in D (44%), third highest in selenium (87%) and provide reasonable choline (16%). Scallops provide 102% of B12, excellent choline (30%), and 45% of daily selenium. Shrimp provide excellent B12 (78%), chart-topping choline (36% - followed only by that found in egg yolks), and a selenium content (102%) second only to tuna, which we do not recommend due to high mercury content and overfishing.

Apart from these unique nutrients, all four sea creatures provide excellent protein, at approximately half of the DRI, and critical, anti-inflammatory omega-3 fatty acids. Salmon and Sardines each provide more than half the DRI of omega-3s, while scallops and shrimp each provide 15%. Lastly, all four are extremely low in mercury levels and other toxins (if the salmon you eat is from Alaska, which it should be - either sockeye or coho), making them the safest and most sustainable in the aquatic world.

Nuts and seeds

This is another broad category to lump together, but is done so intentionally here. We typically use both food gropus as garnishes: that is, they don't make up the focal point of a meal or even a single dish, unless you're given to meals of PB+J. Serving amounts, similarly, tend to be quite small: a generous sprinkle over a salad; a handful eaten as a snack... Lastly, it would be difficult to single out one nut or one seed as a standout. The fact is, when it comes to individual nutrients, there is likely a nut or a seed that tops the list out of any food, and therefore you should include a variety of these heart-healthy, protein-dense, good-fat-filled mini-foods as a regular part of your daily diet. Some highlights: Peanuts. No food is higher (88% DRI) in biotin - a B-complex vitamin essential to skin health and blood sugar balance (since biotin promotes insulin production). Almonds are second highest, at 49%. Almonds are the second highest food in vitamin E (40%), after Sunflower seeds (at 82%). Vitamin E is a potent anti-oxidant that protects cells from free radical damage, and protects against heart disease by preventing the body's cholesterol from becoming oxidized. Flaxseeds are the food world's reigning champion (133% DRI) in omega-3 fatty acids, which, as we've seen in Week 3's post, are essential fats that reduce chronic inflammation, bad cholesterol, blood pressure, risk of stroke, heart disease, arrythmia, arthritis and dementia. Hemp seeds are a close second, at 127%, with walnuts following closely, at 113%. You should include all of these as a regular part of your diet. They all provide double the amount of omega-3s found in those cold water, fatty fish that we love so much and discussed above, like Alaskan salmon and Pacific sardines.  Sesame seeds - the kind often found on that decidedly unhealthy bagel we love so much - are the highest food in copper (163% DRI). Cashews follow next, at 98%. Sesame seeds, pumpkin seeds and cashews each comprise a quarter of your DRI of zinc - the highest of any plant-based food. Zinc is an essential nutrient in promoting good immune function and skin health. For men, zinc also increases both the motility and quantity of sperm. Lastly, oddly, low levels of zinc have been associated with loss of taste and appetite. Protein? One serving of hemp seeds delivers 22% of your DRI - more than any other plant-based food, after beans. Almonds, cashews, walnuts, flax and sunflower seeds each deliver approximately 10% of your protein DRI. If you're a vegetarian, nuts and seeds are important sources of this tissue-building and -repairing nutrient.

Week 8: Cancer and Diet - a relationship

Let food be thy medicine and medicine be thy food.

Hippocrates, the author of that statement and the sentiments behind it, was not a hippie quack, a denier of scientific progress or a fearful skeptic of doctors. He is, more than any other, the person who established medicine as a profession separate from philosophy and theology, instituting clinical practice as its methodology. Our experiences with doctors today are largely built on the foundations he laid 2,500 years ago, and he is accordingly considered the father of Western Medicine. Upon licensure, all physicians are still required to take an Oath to uphold the standards contained in a text that he wrote. According to Wikipedia, 'Hippocrates is credited with being the first person to believe that diseases were caused naturally - not because of superstition and gods.'

But just what is it in nature that causes disease?

The answer is incredibly simple. But to uncover it, to believe in that discovery, and to learn how to foster its opposite - health - is an uphill battle. First, we have lost our intuitive connection with food. If you were not born into aristocracy, then 100 years ago you were most likely a farmer, and understood plants, seasons, soil and yield. Today we understand none of it, since as we saw in Week 7's post, fewer than 1% of us still farm. Second, since industrial food conglomerates largely supply the foods that we no longer grow ourselves, their executives are the people determining how healthfully we eat, via the decisions they make and the products that emerge from those decisions. And their chief - if not singular - goal is to make money. This distinction bears little resemblance to the goal of the small farmer insofar as feeding his/her own family, where nutrition comes first. The bigger the company, the greater the influence small decisions in cutting costs have on the 'bottom line', whether in profitability to them or health to you, which are usually at opposite ends of that equation. Besides, there is so much food choice in supermarkets, gas stations and pharmacies today - to say nothing of national restaurant chains - that these companies are engaged in sales warfare, and must compete for your dollars. Overwhelmingly, this is accomplished via sophisticated marketing, through which we are invariably sold a story to lure us into brand loyalty. And this rarely has anything to do with how good something is for you. Quite the opposite: the less healthy and more engineered a product is, the more companies profit and hence the more they invest in selling it. And the strategy succeeds in large part because it's nearly impossible for us to gauge the actual healthfulness of most food products, since the long list of engineered substances they comprise are things we've never seen, smelled or touched in Nature. And so we rely on others to tell us what's good for us, and must spend our mental energies trying to divine truth from market-speak. We covered this phenomenon at length in Week 4's post: Food Words - Science or Snake OilThird, the food industry that dominates the West has so successfully taken control of the business of food via advertisements, websites, games, characters, lobbying, national policy and even Law, which are aimed collectively at creating economic health, that it is near impossible to practice healthy eating without overcoming the tidal wave of temptations that are designed to prevent most of us from doing so. It's just not good business.

To come back to that 'incredibly simple answer' to what causes disease, it's the processing of our foods. But if you've been following us closely, you already know that. We could fill multiple posts simply tabulating the specific health risks associated with each engineered food-like substance. Instead, we try to include one example each week that illustrates the point. In week 6's post, we learned that the modern process of milling wheat into flour - in which it is stripped of its bran, germ, endosperm, fiber and bulk (coarseness) - results in a 50% content loss of vitamins B1, B2, B3, B9 (folate) and E, and an equal amount of calcium, phosphorus, zinc, copper, iron, and fiber. We learned that in addition to that loss, the resulting wheat flour converts immediately into sugar once it reaches your stomach, where your pancreas starts going haywire producing insulin and spiking blood sugar levels. This week we will take it a step further, and explore the relationship between wheat and cancer.

Wheat flour is just one of many high-glycemic foods, so named because as we just mentioned, it converts quickly into sugar once ingested. A food's glycemic index is a tool for understanding how quickly and how much foods raise your blood sugar level once ingested. High glycemic foods are known to seriously increase the risk of the now-familiar triumvirate of modern disease: type 2 diabetes, heart disease, and cancer. This article by Harvard's School of Public Health provides a good overview on carbohydrates and blood sugar. Another good resource for understanding the glycemic load on common foods, posted by Harvard Medical School's Publications division, is here. In the HMS link, you'll notice that the list is overwhelmingly comprised of highly processed foods that make up 90% of our diets, according to Eric Schlosser, author of Fast Food Nation, and also covered in Week 7's post.

Why focus on wheat? Because it's one of the most consumed foods in the United States, via sandwiches, pastas, snack foods, baked goods, desserts, cereals and even salads. And so unpacking what we consume and how we consume it is of great relevance to the discussion of cancer, as we'll see in a moment. 

First, let's look at the difference in the glycemic loads of two ingredients that to the typical shopper are opposite in health promotion: those of  'white' flour and 'whole wheat' flour breads. Both rate an identical 71 on the glycemic scale's 100-point index, qualifying them as high-glycemic foods - i.e.: quick to convert into pure sugar. Yet we are ever seduced by marketing campaigns into thinking whole wheat is healthier than 'white' wheat. It is, but only if consumed in whole grain form - i.e.: not milled into flour. Once wheat of any kind is milled, as the majority of so-called whole wheat products are, there is precious little difference. They become sugar and are devoid of the key nutrients that unmilled wheat carries as a living plant. Thus we encourage you to read food labels carefully, and avoid flour-based products altogether. If it says 'flour', it's simply not good for you. This resource by the Whole Grains Council allows you to find whole grain breads in a searchable database, to find good products or see how the ones you use measure up. In general, we highly recommend replacing non-whole grains (i.e.: any flour product) with their less processed counterpart. Sprouted grains are especially valuable, since beyond comprising whole grains, the act of sprouting lowers their gluten and starch content while preserving valuable enzymes and amino acids. These are often referred to as 'live' foods, and can be found easily in national grocery chains, in addition to specialty food shops - sometimes in the freezer section. A good resource that lists and grades sprouted grain-type breads is here

So what do high-glycemic foods have to do with cancer, anyway? Everything. The sugars promote insulin resistance. Insulin resistance creates and environment that is conducive to tumor growth in your body, according to the American Institute of Cancer Research. For example, the risk of colon cancer increases by 300% in a high-glycemic diet, according to Dr. Liu and his fellow researchers at Harvard Medical School.

Which brings me to a personal story.

In the Fall of 2003, I received a call from my brother Jordan, a 38-year old Harvard-trained physician and proponent of holistic healing. Holistic healing centers on the belief that psychological health and diet are partners with Western medical science in providing long-term health. I was living in Hong Kong at the time, and he in Western Massachusetts, in no small part because of its proximity to both the Kripalu Center for Yoga and Health, where he meditated regularly, and the Kushi Institute, the American epicenter of Macrobiotics where he took most of his meals and learned all of his dietary practices. This was for two reasons: first, because of the ulcerative colitis from which he had suffered since the age of seventeen and which had wreaked havoc on his large intestine for more than half of his life; and second, because as an undergraduate student, he had taken a sabbatical from Harvard to live among a specific group of Tibetan monks who had proven through meditation to be able to exert a high degree of physiological control over their bodies. And his interest in learning from them was related to his own health challenges.

On the phone in Hong Kong, Jordan told me that his cancer had returned - for the fifth time - and that it was stage IV. Our family had lived through his first - a pineal blastoma (brain cancer) diagnosed at the age of 22 - from which he later became the disease's first-ever recorded long-term survivor. I knew about his ulcerative colitis and that it increased his risk of colon cancer, if untreated surgically. What I didn't know was that in the years between that odyssey and our phone call, he had already twice fought colon cancer; that this was his third such diagnosis; and that he had chosen to keep this information from his entire family. The reason, in part, was because he had declined surgery both times, striking a recurring bargain with his frustrated doctors: that if the cancer hadn't completely disappeared in twelve months following the diagnosis, without surgery or other Western medical intervention, he would allow the operation on his colon to take place. His plan was to heal himself through meditation and diet - and nothing else. And he knew our family would have likely pressured him emphatically to operate.

Like Hippocrates, my brother was no quack. He was a member of Mensa since the age of 10. He enjoyed our century-old high school's highest-ever grades. He went to Harvard at 17, after 11th grade, where he was elected Phi Beta Kappa and graduated Magna Cum Laude. And he finished Harvard Medical School as its valedictorian in spite of tackling brain cancer during his first year - the cancer from which he had been given a 0% of surviving. Jordan was a remarkable human being by every possible measure. He also firmly believed - to the point of putting his own life literally on the line - that his and others' path to health was through connecting his mind with his body, and through diet.

Twelve months after the onset of both of his battles with stage II colorectal cancer, by adhering to nothing more than a self-prescribed regimen of daily meditation informed by his Tibetan experience and a strict macro-biotic diet that Michio Kushi himself had created for my brother at his institute, Jordan's tumors disappeared and were, upon each final medical examination, untraceable. Both times, his doctors' reaction was the same: 'It's impossible'. And both times, my brother felt vindicated in his beliefs.

Back in Hong Kong, Jordan told me on the phone that this latest colon cancer was Stage IV, having spread to his lymph nodes and through them to other organs. He had chosen to tell us - his family - only because of this. He had entered hospice so that he could free himself of daily responsibilities, to allow him to re-double his focus on healing himself. He insisted, emphatically, incessantly, that he had no intention of dying. 

My brother lived another nine months, battling 25-plus tumors everywhere from his brain to his lungs to his stomach and beyond. The largest - in his stomach - was the size of a cantaloupe. The week before that - the last in which he was able to articulate his thoughts - he reiterated that he had no intention of dying, but instead was grappling for one final piece to the mental mystery of healing. To his last breath, he felt he could heal himself, as he had done so many times before.

_____________

I include this story not to suggest the mind's absolute control over the body, or that diet alone is a panacea. Jordan's is, however, one of countless examples - in this case a very personal one - that points to the equally irrefutable influence of both diet and our psychological state over our health. My brother would not have been able to make his tumors disappear had his diet, or mind, or both not supported it. In tribute to my brother, I offer a web link to the only online presence he has: 2 enlightening interviews at the 2000 Macrobiotic Summer Conference, in which he discusses his battles and his medical philosophy - here.

We at FFFL are not doctors, oncologists, or cancer researchers. Cancer may well not be 'curable', capable only of going into remission, whether temporarily or permanently. It is likely caused by factors that are equally genetic, environmental and chemical. That said, diet has been proven many times to slow, stop or reverse cancer's spread - often completely, in people across the globe. The same holds for other chronic diseases that are as varied as the stories and people associated with each. I include links to just five testimonials/videos below in which the only common thread is the adoption of a plant-based diet and a resulting remission of cancer. To reiterate: we are not in any way advocating refusal of conventional medical treatment in the case of a cancer diagnosis. Our interest lies in exploring and sharing what we have learned about the very real power of diet in influencing health, lowering risk and reversing disease. Some stories:

  1. Ruth Heidrich, PhD - breast, lung, bone and liver cancer. Cancer-free since 1982
  2. Kelly Binkoski - invasive ductal carcinoma, triple-negative. Cancer-free since 2014
  3. Scott Gill - stage IV colon cancer. Cancer-free since 1990
  4. Candace-Marie Fox - stage III thyroid cancer. Cancer-free since 2014
  5. Kris Carr - stage IV liver and lung cancer. Cancer-stable since 2005

Moving onto to diet itself, let's look at three specific foods (or groups), their relevant key nutrients and the current science that links them to cancer prevention. A powerful paper prepared for the World Health Organization (WHO) jointly by the University of Oxford, the National Cancer Institute and Harvard University's School of Public Health - included in full here - proposes that dietary factors account for 30% of all cancers, making it second only to tobacco use in cancer promotion. In one section, they list diet as being responsible for 80% of the increase in colon cancer rates between developed and developing countries, where colorectal cancer rates are ten-fold higher in the former than they are in the latter.

The most studied group of cancer-fighting foods are crucifers - aka brassicas. These include broccoliBrussels sprouts, cabbage, cauliflower, collard greens, kale, kohlrabi, mustard, rutabaga, turnips, bok choy, and Chinese cabbage, as well as arugula, horse radish, radish, wasabi, and watercress. All crucifers contain sulfur-containing compounds called glucosinolates, which have been shown to reduce certain types of cancer, either by removing carcinogens from the body before they can alter DNA, or by preventing normal cells from being transformed into cancerous ones. They are of particular interest in the prevention of lung and colorectal cancers. It is advised to consume these foods raw, for two reasons: 1 - the act of chewing results in glucosinolate hydrolysis - which creates the indoles and isothiocyanates that do the protecting; and 2 - cooking inactivates the enzymes that catalyze the all-important hydrolosis that protects us. Nutritional scientists also recommend cruciferous vegetables for their ability to fortify your gut's lining. This lining is all that separates the contents of your gut from your bloodstream. The anti-inflammatory, immune-strengthening properties of crucifers' indoles strengthen the lining, allowing toxins to remain trapped inside and be purged without seeping into your bloodstream and causing inflammatory havoc. Table 1 midway through the linked article here from OSU's Linus Pauling Institute lists crucifers in order of their glucosinolate quantity.

Coffee is the most popular drink in the United States. 83% of us drink it - making us the world's largest consumer. Coffee has several compounds that are of interest with regard to cancer. Caffeine speeds carcinogens' (and other toxins') passage through the digestive tract, reducing the time our bodies are exposed to them and lowering our risk of colorectal cancers. It also contains the antioxidant cholorogenic acid, which reduces inflammation and promotes self-destruction of cancer cells. Lastly, coffee's lignans regulate cell growth and promote the self-destruction of abnormal cells, including cancer. More information on coffee's anti-cancer properties can be found at the American Institute of Cancer Research (AICR) here.

Beans are an area of great interest, and not just for their cancer-fighting properties. The plant kingdom's best source of protein, beans are also vitamin and mineral powerhouses. Beans are high in fiber, which creates the sensation of fullness and helps regulate digestion, pushing toxins and carcinogens through digestion more quickly, as with coffee. Further still, beans are low in sugar, which prevents over-production of insulin, helping to decrease hunger. Together, these properties significantly assist us in achieving weight loss and reducing body fat, lowering the risk of inflammatory diseases like type 2 diabetes, heart disease and cancer. Lastly, beans contain the plant world's highest levels of anti-oxidants, which helps us to eliminate free radicals that have been cited widely in cancer prevention studies. In one, the National Center for Biotechnology Information conducted an eight-year study in Uruguay - where legumes are a major part of the national diet - and found a those individuals in the top third of bean (and lentil) consumption had significant decreases in the risk of the following cancers: oral cavity, pharynx, esophagus, larynx, upper aero-digestive tract, stomach, colorectal and kidney. AICR concurs that regular legume consumption convincingly reduces the risk of colorectal cancers - citing both its fiber, which we've discussed, and its folate, which regulates DNA and cell growth - as key to their conclusion. AICR is a treasure trove of information on plant foods and their ability to reduce the risk of cancer. We encourage you to explore their links and data related to a number of food groups here.

On the flip side, certain foods and their effect on our physiognomy have been shown to greatly increase our risk of cancers. These include red meat (colorectal cancer), alcohol (mouth, pharynx, larynx, oesophagus, colon and breast cancers) and body fatness - primarily caused by a high-sugar, highly processed diet (cancer of the oesophagus, pancreas, colon, breast, endometrium and kidney). Minimizing intake of these foods and remaining lean are of central importance in reducing risk. 

So what to conclude?

Plant-based foods are not a panacea. Eating crucifers will not guarantee you will live a cancer-free life, nor will a diet that includes adzuki beans guarantee a reversal in your colorectal cancer diagnosis. We do not encourage you to forego the (surgeon's) knife in favor of the (table) fork. Those are personal choices, and surgery is directly responsible for innumerable lives being saved across the world. 

What we are saying is that there is abundant nutritional, biochemical and molecular evidence, researched and supported by world's most respected institutes, that a plant-based diet in general - and one that includes key nutrients and food groups in particular - directly lowers your risk of many cancers. The most comprehensive book ever published on the links between food, nutrition, physical activity and cancer prevention, a summary of which can be found here, includes a fantastic matrix on pages 8 and 9 that maps foods to their likely influence on cancer factors. Created by a global partnership of more than 200 scientists and experts in 2007 and funded by the World Cancer Research Fund (WCRF) and American Institute of Cancer Research (AICR), the full report - all 537 pages of it - can be found here.

Beyond food, we know that non food factors significantly contribute to your overall state of health: your genetics, lifestyle (e.g.: smoking), psychological well-being and stresses, as well as environmental factors (e.g.: air pollution), quality of sleep, level of fitness, etc. etc. 

But food is our fuel. It feeds us on a molecular level and promotes or inhibits every one of the millions of bio-chemical and bio-mechanical processes that keep us alive and healthy, or make us sick. Food influences what genes express themselves, and which are suppressed. What you put in your body matters - more than anything else - and can influence the other factors we listed above significantly. Without a healthy diet, like so many others before him, my brother's life would have been considerably shorter that it was. And while death by cancer at the age of thirty-eight is a tragedy, his diet bought him the most precious of human commodities - one for which I will personally be forever grateful and which made the difference beyond all others. 

Time.

 

 

Week 5: Diets - Why They Don't Work

"Prohibition didn't work in the Garden of Eden. Adam ate the apple."

This poignant quote by Vincente Fox was about Mexico's drug problems during his tenure, and his attempt to legalize them to take the wind out of the cartels' sails. It didn't happen, of course. But he could just as easily have been referring to diets today. Why? Hunger for the forbidden goes back since long before the story of Adam was written. It's in our genetic code.

We saw in Week 1's post that we need all nutrients found in the human body, in adequate supply, to be present and available when needed in order to function optimally. When it is short-changed of nutrition, as during diets, the body signals the brain to crave whatever it's missing in order to spur the action that will result in its obtainment, short-changing our attempt to deprive it. Diets don't work. They invariably miss the central point that the body needs food from all nutrient categories - categories that include foods that every diet, from the first to the latest, has tried to omit.

Understanding what these nutrients are, what they do for us and where to find them is the first key - and the primary focus of this website. Once we can distinguish health-promoting foods (those produced by nature and which promote health) from unhealthy foods (those altered and/or produced by industry and which promote sickness), we can move on to issues of sourcing, nutrient balances, combinations and preparations that best support your long-term health.

But first, we need to understand the body's biology insofar as how it sees food. Which brings us to diet strategy number one: reduce calories. This is a dangerous game, because it backfires and results in weight gain. To explain: the body is extremely good at managing its fuel supplies. In the absence of adequate intake, the brain (correctly) perceives the loss as a threat, and starts producing large quantities of cortisol and adrenaline, the so-called 'stress hormones'. These in turn send a signal to the body's metabolism to slow down, conserve fuel and reserve the rest for later. Slowing your metabolism prevents nutrients from being absorbed and calories from being burned, i.e.: used up. Instead, the body stores the nutrients it's trying to protect in fat cells, making us gain weight and girth. So, instead of nourishing the body and fueling its metabolic processes, we are telling it to hunker down and hoard what little it has, much as a squirrel does in storing nuts for a long winter. If the nuts aren't eaten and used up, they accumulate. Except that in our case, instead of nuts sitting in a tree, we store fats in our bodies. The result is that losing weight becomes even harder.

This is why dieting by calorie reduction is a game of attrition: even if your overall weight reduces (maybe you're exercising in addition to limiting intake), your willpower to keep starving yourself is pitted continually against your body's inexhaustible ability to produce stress hormones and slow your metabolism. Eventually, biology will triumph.

So much for diet strategy one. Let's look at another common strategy: reduce fat intake. We saw in Week 3's post that fats are an essential set of dietary nutrients without which our bodies cannot properly function. Fats fuel metabolism. Your brain is comprised of cholesterol and fat - primarily saturated - and needs to be fed in order to function. Without fat, calcium cannot be absorbed by your bones, making them weaker. Fat insulates your liver from the damage of alcohol and medications, and fat coats your nerve endings, protecting them from damage. Further still, unsaturated fats are critical anti-inflammatories that keep the body from attacking itself. 

Fat - saturated or unsaturated - is not the enemy. They are produced by nature for the reasons listed above - to fuel life, when paired with the other nutrients the body evolved to need and use: vitamins, minerals, fiber, carbohydrates, protein and water. The fats that do cause damage are man-made fats, which are called trans-fats. We have covered these extensively in Week 3's post, and won't duplicate that discussion here. 

Besides the profusion of illnesses that inadequate fat intake promotes, the loss of this fuel source chemically tells the body to signal the brain to replace it. But with what? Since the 1977 release of the McGovern report, the 40-year trend in the United States - and subsequently elsewhere - has overwhelmingly been to substitute fats with carbohydrates. Besides fueling vastly different functions in the body, carbohydrates in their most common form - the refined starches, flours and sugars found in nearly every boxed, bagged or bottled item in your supermarket - are not just nutrient poor: they are overwhelmingly responsible for the raft of chronic diseases we as Americans - and those who mimic our dietary habits - are experiencing: heart disease, type II diabetes, cardiovascular disease and cancer, to repeat a few here, conveniently packaged in a human host. A good article by Harvard's School of Public Health on the subject is linked here.

So we can see here that the two most common approaches to dieting: 'eat less' and 'reduce fat intake' are destined to fail and moreover can and do cause severe damage to the people implementing either.

A proper diet - defined in one entry by Miriam-Webster as 'habitual nourishment' - not dieting - defined by M-W in another entry as 'a regimen of eating and drinking sparingly so as to reduce one's weight' - must be the foundation of any approach to improved physical and bio-chemical health, if it is to have any chance of success. And a proper diet, if you've not guessed by now, begins with the selection, preparation and consumption of quality, whole, natural, 'unimproved' foods as found in nature. That means eating foods from all nutrient groups that are high in nutrient density and variation, and are as fresh as possible to avoid spoilage and the deterioration of nutrient quantities and qualities. These are the foods with which we evolved, and with which we coexisted almost exclusively until the recent past.

There are other considerations besides food that greatly influence one's health beyond diet. These are obvious, but are worth repeating in brief here because when we speak about diets we are essentially talking about returning to a state of optimal health that supports happiness, longevity and vigor. Adequate sleep is one. Reduction of stress is another. A third - the focus of much ink and in itself a multi-billion dollar business - is exercise.

What we need to remember is that exercise is the expenditure of energy - energy that comes from foods. The more we use, the more we deplete our resources, and the more we need to eat in order to replace what has been lost. At rest, without moving, our bodies use up roughly 1200-1600 calories per day to feed its automatic processes, such as pumping blood, producing cells, operating lungs and other organs; repairing itself, etc. This is called your basal metabolic rate, and you can calculate yours here. From a purely caloric standpoint, if you slept for 24 hours, your body would use that amount to fuel itself. 

Calories ingested beyond these are either stored as fat or used to feed voluntary processes that are the sum total of our physical activity: walking, talking, working, playing or exercising. So you'd expect that what follows is the simple need to consume only as many calories as you use - simple math. Right? Well, yes in mathematical terms. But as Dr. Mark Hyman, MD, writer and Director of the Cleveland Clinic Center for Functional Medicine says, "food doesn't just contain calories, it contains information. Every bite of food you eat broadcasts a set of coded instructions to the body - instructions that can create either health or disease." He illustrates this point in a web posting here, in which he compares the consumption of 750 calories of soda with 750 calories of broccoli. In terms of size, the first is a 'Double Gulp' from Seven-Eleven, while the latter is 15 servings, or 15 cups / 5 lbs., of broccoli - unlikely as your stomach cannot hold that much volume. Regardless, the theoretical comparison is an important one. Both sources are predominantly carbohydrates, but here again, to paraphrase, a carbohydrate is not a carbohydrate. The results of our consumption of each, in brief: the soda promotes what he calls 'biochemical chaos', including unchecked fat production, inflammation, bad cholesterol and blood pressure - delivered via 46g of sugar. The % of your daily requirement of vitamins, minerals, proteins and fats that the soda delivers? ZERO. Not a single vitamin, mineral, fat, fiber or protein. On the other hand, an equivalent caloric intake of broccoli - however unlikely - contains from 100% to 3,000% of your daily need of eighteen different essential vitamins, minerals, protein, fiber and omega-3s, which is astounding and what makes broccoli one of the plant world's most super superfoods, even in one serving. There is essentially no relationship between the two 'foods'. Dr. Hyman quips that a kindergarten class knows this, and yet 'every major governmental and independent organization has bought into [this] nonsense' - that a calorie is a calorie. 

Which brings us back to exercise. Michelle Obama has spent much of her professional life as First Lady promoting a campaign called 'Let's Move', aimed at reducing obesity, particularly in young children. The term was originally meant to provoke a call to action (the movement), and she regularly addressed underlying causes of obesity, namely the foods that caused them. However, the candy, soda and processed food lobbies saw the potential loss of control over their marketing message, and banded to 'partner' with Let's Move in providing corporate sponsorship. Kellogg, Coca-Cola, Nestle, General Mills... all of them now in control of the marketing message and opportunities for yet more food product to be introduced to 'address the issue'. The result: over the past few years, Let's Move has gone from attacking obesity sources (i.e.: dangerous food-like substances) to addressing its symptoms - namely getting outside more and moving your body, in a perversion of its original name. While exercising is positive for anyone and critical to holistic health, look again at the numbers: Americans are exercising twice as much as they did 30 years ago, while in the same time the rate of obesity has also doubled, as conveyed in the informative documentary, Fed UpSomething doesn't add up. And that something is what people are choosing to consume.

To wit: since joining Let's Move, the food industry in principle has taken no products off of shelves, but rather have added new products to address a new market: the 'healthier snack alternative'. In just one example, partner Nabisco created a new product: the low-fat Oreo. At 150 calories, it's 9% less caloric than 'regular' Oreos. The accompanying reduction in sugar: zero. A three-cookie serving contains the same whopping 56g of sugar as its 'original' version on the shelf. You'd have to eat twenty plates of pasta (another carbohydrate) to glean the same amount of sugar contained in three oreos. 

In short, Let's Move has been neutralized; industrialized food product companies have gained market share; and nothing has been done to reduce the underlying cause of obesity, which would necessitate the reformulation or better yet removal of scores of products from store shelves. We will leave the discussion there, but to read more, here's a good article on the subject.

We've seen that calorie reduction, fat reduction and exercise alone do not promote health or weight loss, and that we need to change what we eat in order to truly be healthy and lean. But what about the proliferation of so-called fad diets? Atkins. Paleo. Juicing. Low-carb. These are just 4 of the more recent fads created to move product and make someone money. The key problem? They all emphasize one food or food group. They ignore the entire point: that variety is key to health. This includes fats, carbs, fiber, vitamins, minerals and protein - all present in the body and all present in nature - for the reasons we've explored in this and our other posts. Juicing? We need the fiber that juicing removes in order to regulate digestion and nutrient absorption. Paleo? (High-quality) cultivated carbohydrates that Paleo forbids provide critical nutrients that allow us to ensure food supply over a larger population and broader nutrient access. Low-carb? Ditto. Atkins? It's the pre-Paleo Paleo Diet. Beyond being unhealthy, diets ignore human psychology, which as we saw at the beginning of this post creates hunger - in this case, psychological hunger for what we can't have, and leaves us with the overwhelming feeling that we are denying ourselves, whether or not our bodies are receiving adequate nutrition. Thus, they are doomed to fail like calorie reduction: the body will produce enough hormones to eventually overcome our willpower. So what may work in the short term will invariably fail over time. Unless we change our habits, starting with an education like this one.

If there were a diet that worked, we would not keep inventing new ones. Nature devised a successful diet from which we evolved into being. Start trusting her instead of business executives.

Stop eating junk - all of it. Eat real food - the kind grown by nature. Eat for nutrient density, completeness and balance - in the right amounts. Keep tabs on what you've eaten. Prepare it at home when possible and practical; and make the healthiest choices at food stores and restaurants when you cannot. 

And Let's Move... on.

Week 1: Nutrients A to Z - An Introduction

We are what we eat.

There are no truer words to describe our relationship with food. Our bodies contain 14 vitamins, 7 macro-minerals and 9 micro- (or trace) minerals, as well as a number of carbohydrates (fiber, starch and sugar) amino acids (proteins) and fatty acids (saturated and unsaturated). 

The body needs every one of these nutrients to function, and as it uses each up, needs to replace it in order to support the body's living tissue - brain and body alike - as follows:

As soon as we eat something, the body begins to break it down so that it can use its nutrients. This is called metabolism: a series of chemical reactions that transform food into components that can be used for the body's basic processes. Proteins, carbohydrates and fats move along intersecting sets of metabolic pathways that are unique to each major nutrient. Fundamentally - if all three nutrients are abundant in the diet - carbohydrates and fats will be used primarily for energy while proteins provide the raw materials for making hormones, muscle and other essential biological equipment.

Some nutrients - like carbohydrates - are used very quickly, and must be replenished accordingly. Others - like fats - can be stored by the body for later use. Fats that aren't used right away are packaged in bundles called triglycerides and stored in fat cells, which, according to Dr. Erika Gebel, PhD, have unlimited capacity. 

Vitamins fall into two basic categories: fat-soluble (vitamins A, D, E and K) and water-soluble (all B-complex vitamins, C and folate). Fat-soluble vitamins are stored in chylomicrons (fat globules), and what is not used is stored in the body's tissue, where it tends to remain. For example: in northern climates, adequate summer exposure to sun allows the body to create and store enough fat-soluble Vitamin D - used for bone health - to get you through the sun-starved winter months. Water-soluble vitamins, on the other hand, travel freely through the body and are absorbed by various tissue for immediate use. Excess amounts of these are usually excreted by the kidneys, in the form of urine. Accordingly, water-soluble vitamins - like Vitamin C - must be replenished more frequently - almost daily. Thus, from a dietary focus, we need to consume adequate fat-soluble vitamins over the long term, but replenish water-soluble vitamins continually.

Like vitamins, minerals fall into two basic categories: macro-minerals (calcium, phosphorus, magnesium, sodium potassium, chloride and sulfur) and micro-minerals (iron, manganese, copper, iodine, zinc, cobalt, molybendum, selenium and bromine). Macro-minerals are thus named because the body needs them in larger doses than it does micro- (or trace) minerals. Food sources of these nutrients are as varied as the jobs they perform in keeping the body's bones, blood, organs and systems functioning properly. As with vitamins, the best way to ensure adequate intake of each is to adopt a very varied diet of both plant-based and animal-based foods, as some nutrients are almost exclusively found in one or the other. There is a reason we are called omnivores: it is not simply because we enjoy the act of eating food from both groups; it is because our bodies need them in order to function as we evolved to.

As we'd expect, the inadequate intake of any of these - or in the case of nutrients that the body stores, an excess - prevents the body's 'machinery' from functioning optimally. The result - very slowly or very quickly, but invariably - is illness. Moreover, there are several factors we need to consider with respect to foods: nutrient quantity (which generally declines over time, diminshes with an increase in factory processing, and is affected by preparation choices at home); nutrient quality (nutrients in fortified foods and supplements - while better than none - are not nearly as effective as those in real foods); and nutrient bio-availability (the absorption of which can either be enhanced or hindered based on the combination of the foods we eat - not just whether or not you ingested it.)

It may sound obvious, but the best source of these nutrients is food - real food, as found in Nature. We evolved because of it and with it; our genes have adapted - and continue to adapt - to use it; medically, we are uncovering bits and pieces about how it works and what it does to us; and we are just beginning to understand that the interactions between nutrients are far more complex and co-dependent than we previously understood. We also know that the human body has not evolved beyond needing any of its developmental nutrients - despite what food engineers, the multi-national agribusinesses that employ them and the shareholders who demand profit above all - would have you believe. We in 2015 are the product of a 50-year trend away from traditional modes of eating and a sprint toward consolidation and homogenization of nutrient sources, which poses a direct conflict with the body's evolutionary need for broad variety of real, high-quality foods. The good news is that nutritional science is catching up with food engineering, as is the consumer's awareness of our need for real food. Luckily, there are still myriad sources of quality produce containing everything your body needs, available at a market near you.

So what are these magical nutrients? What does each one do in detail? What happens to me if one is missing? How fast does the body consume each one, and how fast do I need to replenish it? How much of each do I need? What are the best food sources for each, and which do I avoid? What if I have a special condition or a particular sensitivity? How do I parse marketing-speak from truth amid a glut of information in books, ads and the internet?

In short, what do I need to know to eat well

These are the questions that this website proposes to answer over the next 52 weeks. Each week we will post another piece to the puzzle. In a year's time, we intend to have created a complete guide to nutrition: what you need and where to source it in the 'real world' where time, funds and access are sometimes limited. Finally, how to begin effecting change immediately.

Central to the health challenge is a daunting Goliath nicknamed Big Ag  - the agricultural monopolies whose practice of producing 'food-like substances' is anything but nourishing or varied, consisting primarily of infinite forms of the same basic cash crops that dominate the farming landscape and your supermarket: corn, soybeans and wheat. Generating over $110 Billion per year in cash sales in the United States alone, these three crops, like their parent companies, monopolize the shelves, from the obvious snack and packaged foods to the less obvious fruit and vegetables coatings - the latter made invariably from a corn starch derivative. With massive advertising budgets and even greater influence on Capitol Hill (the subject of a future blog), Big Ag have thoroughly saturated the consumer market. Their success has grown exponentially alongside an alarming human trend toward lower expenditure in both food dollars and time spent creating meals. Worst of all, Big Ag's food-like products are by most scientific accounts directly responsible for a dramatic increase the incidence of many, if not most, of modern society's chronic diseases, from cancers to diabetes to heart disease to cardiovascular disease to osteoporosis and beyond. According to a phenomenal paper published in the American Journal of Clinical Nutrition, more than 280,000 people die directly from obesity each year in the United States alone; 38.5% of all US deaths are due to cardiovascular disease; and fully one-third of all US cancer deaths are due to nutritional factors.

If this sounds scary, it is. It's also the reason we have created this site. 

There are solutions. 

So here we go...
