The Soy Conundrum: Part 1

This is a HUGE topic that would take volumes to adequately explore, but I’ll try to give you the highlights. If you’ve been following health trends, you are likely as confused as most Americans about soy. Is it healthy for human consumption? My answer is a tentative maybe. Here’s why...

How Soy is Grown: About 85% of all soy grown is now genetically modified. Even if you don’t care about the genetic material itself, what this tinkering has done has allowed these crops to be even more heavily sprayed with pesticides and herbicides which travel up the food chain. We are seeing more and more research coming in now about how these residues contribute to disease, especially in children.

Health Claims: Most of the health claims are marginal at best. When you actually read through the literature and the research, you’ll find there are small benefits to LDL reduction associated with eating soy (although it’s hard to determine if that is the reason or if it’s because participants traded conventional meats for soy a few meals a week and maybe it was really just the removal of the damaged fats and fat soluble toxins that did the trick). Most of the positive health benefits are found from using fermented soy foods, not from products like “Tofurky” or SPI (soy protein isolate).

Protein Quality: You will hear many proponents of vegetarian and vegan diets claim that soy offers a complete protein source. While it is true on a chemical level that soy offers a broad spectrum of essential amino acids, it also important to understand that soy contains chemicals that slow or prevent the digestion of proteins and significantly impair the bioavailability of their component amino acids.

Human systems simply don’t produce the all the enzymes essential to the complete digestion of soy protein or the breakdown of the “anti-nutrients” that get in the way. When we rely strictly on soy for protein, or have a very high intake of soy products in the diet, we risk long term amino acid and mineral deficiencies that create problems in all our systems including hypothyroidism, anemia and immuno-deficiency.

Anti-nutrients: These are substances that either impair nutrient bioavailability or are chemicals that directly impinge on human systems creating health problems in the long term. One of these problematic substances is phytic acid or phytate. Soy has one of the highest amounts of phytate of any legume or grain studied, and to make matters worse, the phytates in soy are highly resistant to breaking down by heat (unlike phytates found in spinach, for example). Phytic acid blocks the absorption of vital minerals such as calcium, magnesium, iron, copper and zinc. Because we don’t have the capacity to break down phytates, we have to rely on other mechanisms to do it for us. Happily, bacteria can do this via fermentation. This is why fermented soy products are considered by most nutrition experts to be the best form for human consumption. Fermented soy products include tamari (soy sauce), miso and tempeh.

Unfermented soy also contains enzyme inhibitors that block one of your body’s main proteases: trypsin. This is essential in the digestion and breakdown of proteins. Diets high in trypsin inhibitors can precipitate pancreatitis (and other pathological conditions of the pancreas), amino acid deficiencies and gastric distress as the undigested proteins make their way through the intestines.

If you choose to use soy, please choose organic, non-GMO, fermented products, and rotate your protein sources so you don’t rely exclusively, or even heavily, on soy. It is essential that growing children NOT use soy exclusively as their bodies try to build bones and brains. There are plenty of other legumes out there and when combined with a grain you will have a complete amino acid profile, and a broader spectrum of nutrients.

Reader Question: "Is eating yogurt daily good for the average person?"

The short answer: Maybe... It depends... On a lot of things... like your personal biochemistry, the source of the dairy, and the ingredients in the yogurt to name a few. The longer answer: First let’s take a VERY short look at the history of dairy as a human food. Really we should not be able to digest milk beyond when we should be weaned from our mothers, by about the age of six. Waaaaaaay back during when human tribes were far flung around the globe and not in regular contact with each other, the northern European tribes, Egyptians, and other groups who were domesticating cattle began to exhibit a genetic mutation that left the gene responsible for making the lactase enzyme in the “on” position. This meant that these humans could continue to digest the lactose sugars in milk beyond childhood. The tribes who were not exposed to this mutation have maintained their “normal” adulthood lactose-intolerance. This is why many African and Asian populations are largely lactose-intolerant. Today this is changing as genetic material is rapidly mixing as we become a more global society. 



Dairy as a food has changed radically in the last 150 years with the advent of pesticides, industrial confinement dairies, growth-hormone injections, antibiotics and pasteurization. Let’s just look at pasteurization for a minute. This process was largely adopted in an effort to stop the spread of diseases such as typhoid, scarlet fever, and tuberculosis that sickened many people during the early 1900s by way of ingesting contaminated milk products. Pasteurization is now mandated in many states and dairy products must meet certain national standards to cross state lines. The two main pasteurization techniques subject raw milk to temperatures exceeding 161F for 15 seconds (high-heat-short-time; HTST) or 280F for 2 seconds (ultra-high-heat; UHT). The UHT or “ultra-pasteurized” process is becoming more popular so now you can even find milk in tetra-packs on unrefrigerated grocery shelves. 



What does this do to the milk? Consider that milk proteins, primarily whey and casein, are fragile. When they are subjected to high heat, vigorous shaking, or high-speed blending, they begin to break apart quickly into random amino-acid groups or singles in a process known as “denaturing”. The body likes to receive intact un-denatured proteins so it can break them apart into the puzzle pieces it knows how to use. Highly processed dairy products create dubious protein bioavailability for our human systems. In addition, the high heat damages the fats found in milk, including beneficial conjugated linoleic acid (CLA) which helps trigger healthy body composition balance (i.e. supports lean mass and helps the body let go of extra body fat mass). 



Keep in mind that toxins tend to travel most effectively up the food chain in fats (the subject another upcoming post) and you’ll want to avoid any non-organic dairy product as well.



So back to the yogurt question: Yes, unflavored yogurt made from whole, organic milk from grass-fed, hormone-free cows can be healthy for people who are not allergic to dairy or lactose intolerant. Highly-processed, denatured, fat-free, "squeeze-pack" yogurts with loads of sugar or sugar-substitutes and carrageenan thickeners? not so much (and especially not for children). Get the good stuff. Get as close to milk from a happy, healthy Bessie as you can. Get REAL.

Man Parts

Why is it that the topic of “men’s health” always seems to be a synonym for prostate health or erectile dysfunction? Yes, the prostate gland is important, but there is a whole MAN attached to it and his overall health is vital to the health of all his parts. Let’s look at a few things that are important to consider in whole-body health trajectories that don’t get much attention.

Building blocks: We all played with them as kids. You learned about how a wobbly foundation meant that your castle would fall over more easily than a well built one. You learned about how certain blocks fit together better than others. And you learned that using the bigger blocks on the bottom gave your castle more stability.

Translation: There are a few big pieces to focus on for overall health at the foundation level that will make all the difference in the stability and maintainability of health in the long run. The really cool thing is that all of these are under personal control, not the purview of the pharmaceutical companies or the medical community. In most cases, the biggest contributor to health or dis-ease is what we do (or don’t do) every day.

What to Eat? Start with less... Over-consumption of food and the development of obesity is one of the leading causes of all chronic dis-eases in the US and is directly implicated in the development of benign prostatic hyperplasia (BPH), prostate cancer, erectile dysfunction (ED), heart dis-ease, diabetes and more.

One of the greatest disservices perpetuated on the American public has been the idea that a low- or no-fat diet is somehow healthy. The key is the type of fat and where it comes from. You actually need some saturated fats along with essential fatty acids, but fake, damaged or contaminated fats are deadly. Low/non-fat conventional dairy products have been linked to prostate cancer, and high intakes of unprotected omega 3 fatty acids (i.e. not enough antioxidants) are linked to the development of BPH.

The same holds true for proteins, especially animal derived proteins. There are vast differences in health consequences between consuming organic, grass-fed, “happy” beef/dairy and commercial, feed-lot, grain (and “other”) fed beef/dairy. Our biggest problem, however, is likely to be highly processed carbohydrates including products made with refined sugars and flours, refined white rice, and starchy veggies that have been subjected to high heat. High-glycemic index carbohydrates (highly processed carbs and sugars) have been linked to prostate cancer and BPH. If I could make a one sentence recommendation for your overall health it would be this: Eat foods that were grown the way they were meant to live (organically) with the least amount of processing possible and prepared with care. If we all did this I would be willing to bet that 80% of our chronic health issues would magically disappear.

What to Drink: Simple, water. Those studies claiming that red wine is beneficial for heart dis-ease? Yeah, those have been found to be mostly false. Sorry. And beer is one of the worst things to indulge in daily, even more so than sodas which are looking worse and worse as the studies roll in. Coffee? Good news! One coffee drink per day is good for the liver and helps to prevent diabetes. The trick is to eliminate the sugar and only use organic grass-fed hormone-free whole milk or half and half. Soy milk? Let’s just say “don’t go there” and leave that for another discussion. Water. Clean, pure, non-distilled water.

What to Do: Another simple answer, move. If there were a medication that could provide all the benefits of exercise, MDs would be sued for malpractice if they didn’t prescribe it for everyone! Basically there are only benefits, even the side effects are beneficial! It’s no wonder because moving is what we were built to do. This modern age has seen a new ill health syndrome develop called SED or sedentary death syndrome. The less you move the greater your chances of early death or a long, drawn out, dis-ease riddled old age. And is it related to BPH, prostate cancer and ED? You bet. No surprise there. The research all shows that the better shape you’re in, the better ALL your man parts work! (And yes, the sex is better too...)

Get the gunk out. Get moving. Get serious about your health. Get REAL.

Harvest

August is here. Finally. And how. I'm not sure about where you're living, but here in the San Francisco Bay Area it's been living up to John Muir's complaints until yesterday when we blew through heat records. Yesterday my car thermometer registered 107F in Mill Valley which has been fogged in and regularly in the 60s most of the summer. The happy news is that this heat wave means my tomato plants are finally producing! Well, at least the ones that the deer haven't bonsai'd. There's just nothing like a vine ripened tomato you've been fussing over all summer. Having been spoiled by my green-thumb mother who had 1/4 acre gardens during my childhood, I just can't bring myself to buy tasteless, hard, pale commercial tomatoes. They're more like packing material than food.

You know, I find myself saying things like that about so many commercial foods. Think about it, when have you ever bought produce that was actually full of flavor from the local Safeway or Albertsons or A&P? They're starting to get a clue and offering organic versions which are slightly better, but so many of the organic producers are trying to create shippable products that can be picked too early and with a density that doesn't fit all fruits and veggies. Even the produce that is supposed to be dense, like a carrot, remains tasteless when compared to one pulled from your back yard, or from a local farm stand.

Do yourself a favor and treat yourself to a trip to a farmers' market or roadside stand in the next few weeks. Even if you can't find an organic offering, get some fruits and vegetables that are ripened in the field. The taste will blow you away if you're used to everything tasting the same. You don't have to prepare them in any fancy way. Let the flavors of the produce speak for themselves. Have a little butter on your corn or green beans. Have sliced tomatoes with a little fresh basil, sea sale and olive oil. Try a green salad topped with as many different colors as you can find and then just a quick squeeze of lime, olive oil, salt and pepper.

Great food doesn't have to be complicated, it just has to start with great REAL ingredients.
