It would be hard to think of a more controversial subject in the vegan/veggie world than this whole business of eating soy-based products. I heard rumblings about both the supposed good and the supposed evil of soy, early on. So when I started doing serious research for my book all those years ago, I actually went into the discovery process pretty open-minded. Sure, there were certain soy foods that I enjoyed, but hey, if soy was as fucked up as so many claimed it was, I had no problem letting it go. My goal was all about finding the absolute healthiest – and most ethically and environmentally conscious – way to eat, and I was always sure I could achieve this without soy, if necessary.
As I began to peruse the mountain of data, sure enough, both sides were speaking loud and clear. So the only reliable way I knew of to discern what was what, was to do the “research behind the research” of all the various claims I was conjuring up.
Unfortunately, I’ve come to find out that this process of discernment is the exception, and not the rule…particularly where soy is concerned. I’ve seen so many otherwise intelligent experts quote from studies that I know for a fact are blatantly flawed, further perpetuating these falsehoods in the form of soundbites fed to a Google-hungry public. Then these folks go around propagating whatever they happen to read on “search results” page one, without questioning who’s saying it, why they’re saying it, how the supposed study was conducted, who it was conducted on (human or animal), etc. Next thing you know, “soy causes thyroid problems” becomes a national mantra in certain circles, and it was all built upon the weak-ass foundation of some ridiculous study that was done on mice. Insanity.
The Quick Nutshell
So… after many years of research, observation, personal experiences, and plenty of spirited debate, I present to you an excerpt from my book that I feel encapsulates the whole soy story, once and for all. Contrary to what you might be thinking, however, I am not a blind proponent of soy products (as many of this blog’s regulars already know). In many cases, these are highly processed foods that are not in the best interest of your health in the high volume that many veggies or vegans tend to consume them.
At the same time, I have found very little merit in most of the anti-soy hoopla you hear about out there. So, depending on a number of factors (like your total daily caloric intake, total bodyweight, amount of physical exercise you do each day, and so forth), I don’t see any harm in enjoying a little soy each day – so long as you don’t go crazy with the total servings, and so long as you always shoot for the organic varieties. That said, read on to find out…
The Absolute, Bottom Line, Last Word Truth About Soy
Perhaps the single most common legume-based item in the vegetarian/vegan world is soy, which loosely refers to both the traditional Asian forms and the dozens of protein-rich meat and dairy substitutes that have become increasingly prevalent in the mainstream market through the years. Besides the various kinds of tofu, tempeh, and tamari, there are soy-based substitutes for virtually any kind of animal product you can think of, from soy chicken, ribs and bologna to soy milk, cheese and ice cream. The taste, texture and overall experience of these foods is, for the most part, uncanny…especially if you’ve made a full transition away from animal products. For this reason, soy products are often viewed as a godsend to many followers of a plant-based diet. After all, with products like these, it hardly feels like you’re sacrificing anything at all with your veggie regimen.
The good news in all of this is obvious: the transition to the plant-based diet is made infinitely easier because folks can basically substitute the meat and dairy products they’ve been used to eating with various soy “imposter” versions and barely taste the difference. This is why so many companies have joined the soy bandwagon and tapped into an ever-expanding new market of folks who do want to eat healthier, but, of course, do not want to alter their eating habits very much. To this end, soy has its place.
The bad news, however, is this: in the consumer’s zeal to replace all of their favorite animal products with soy substitutes over multiple servings per day, they neglect to realize that they are taking in large quantities of highly processed foods that are typically riddled with sodium and often loaded with fat. (And believe me, with the sheer number of easy-to-prepare or ready-to-eat soy products out there, this is easy to do.) Are they still better off doing this than eating animal products? Sure. But eating high quantities of soy products has its pitfalls, even though many of the anti-soy claims out there are either highly exaggerated or completely without merit altogether. And if it’s a non-organic soy product, then the downside of mega-soy overdosing is exacerbated.
Cause for concern? Read on…
Soyanoia: Putting Soy Paranoia in Perspective
Let’s once-and-for-all address a few of the more pervasive concerns, myths and blatant untruths about soy, based on some of the latest “research.” First of all, much of this anti-soy research is referring to animal-based studies, which are notoriously inaccurate and unreliable in their relevance to humans. One well-known study in particular was done with rats (who, like all animals, have a completely different physiology than us humans), where they were fed an insanely high amount of soy to produce the “negative” results. It is literally one of the only such published studies out there, yet many folks refer to the results of it like they were extracted straight from the Dead Sea Scrolls. Meanwhile, Asians have been eating soy for years and outliving us “fat and happy” Americans by a decade or two without any overt testosterone, estrogen or thyroid issues.
Personally speaking, I find it so ironic that most anti-soy zealots base their entire stance on these ridiculous studies done on animals. Meanwhile, we have an epidemic of heart disease, cancer and a ton of other maladies in our world that are directly and unequivocally attributable to animal product consumption, based on human evidence. (It’s no surprise that most of these supposed “experts” who are the loudest anti-soy proponents will turn around and recommend a battery of animal products for your good health. C’mon, people!)
So let’s address a few of these issues. But first, let’s make a fundamental distinction. The old standbys like tofu, miso, tempeh, and tamari have a rich history as a healthy part of the classic plant-based diet as exhibited by many of the world’s healthiest cultures. For example, these kinds of soy products comprise over 10% of the Okinawan’s diet, and these folks remain among the most long-lived on the planet. Considerably more under the microscope, however, have been the multitude of soy-based animal product substitutes like soy milk, soy burgers, soy cheese, etc., and this is largely where the controversy has been directed. So let’s look at a few of the most popular anti-soy contentions and get to the real bottom line here.
