This is not going to be a blog about losing weight, so if that is what you are looking for, look elsewhere. Sorry.
What I do want to talk a little bit about is the trend within the United States to tout the health benefits of one particular food item for five or six years, and then debunk everything good that was said about that product for five or six years, and then add that food item back to the "it's okay to eat in moderation" food list. Honestly, I think they're all just messing with us, trying to make bigger profits on food products by coming up with new food items and then convincing the general public that all of the old food products are going to kill you so you better eat this new stuff instead.
I bring this up today because a lot of the foods I rely on to keep me healthy have come under attack lately - soy and wheat, mostly - and this bothers me. I sort of feel like I'm sure much of the world did when we were all told to avoid eggs fifteen years ago, and I am anxiously awaiting the day when either some reasonable research comes out or we get off of this "everything is bad for you for five years and then it's okay to eat again" roller coaster.
See, the thing is this - data can be interpreted in really whatever way you want to interpret it in order to support whatever hypothesis you come up with. In the simplest terms, you may have crammed all night for a big biology exam and you got an 85% which makes you proud, but your parents only focus on the 15% of the test you got wrong and ground you. Same result, different interpretations. Or, let's say two groups of scientists perform the same study under the same conditions to determine whether or not smoking is bad for you. The one group zeros in on the calming effect of nicotine, the appetite control, the lowered risk for Parkinson's disease. The other group zeros in on the prevalence of lung cancer and emphysema caused by smoking. Both publish papers on their findings. Both papers will really only talk about the things they want to highlight so it doesn't look like they spent ten years disproving their own hypotheses. No scientist wants to prove himself wrong - he'll lose funding, he'll lose respect within the community, and he'll likely lose his job. On the rare occasion, proving oneself wrong produces another, greater result that then heralds one as a genius instead of a failure (
William Perkin inventing synthetic dyes instead of a malaria cure, for example), but I think most scientists would rather spend their time proving themselves right than hoping for a miracle.
So here is what I know about human biology as it relates to food:
- We need certain amounts of carbohydrates, lipids, proteins, vitamins and minerals to support our basic body functions.
- Some of these things are synthesized naturally in the body.
- What is not naturally synthesized, we get from food - the things we eat and drink are absorbed into our bodies and affect the way we function.
- Whatever we ingest that our bodies can't use is expelled as solid or liquid waste.
Based on this list, maintaining one's health by eating the right foods should not be rocket surgery. Eat things that contain the right amounts of carbohydrates, lipids, proteins, vitamins and minerals and you should be all good, yes?
I say yes.
I think where the confusion comes from is that the right amounts of the right things are not easily defined across the board. In the simplest terms, a 250-lb man has different dietary requirements than a three-year-old girl. There is more of him, he has different musculature, he has different hormonal balances to maintain, and he (hopefully) isn't still trying to grow at the rate a three-year-old is. And this isn't even taking into account conditions like diabetes or lifestyle choices like extreme athleticism that will change your nutritional requirements even more. But the problem in America is that we want to find the one right answer to "how and what should I eat?" that will work for everyone. We recognize so many other differences in ourselves; why don't we recognize and honor the differences in our dietary requirements?
The one that is really amusing to me now is the gluten-free trend. Now, I'm not trying to make fun of those who have Celiac disease - this is a
real autoimmune disease wherein an autoimmune response is triggered in the small intestine when gluten is ingested, and it causes bloating, fatigue, weight loss, and malnourishment. I know people who have been positively diagnosed with Celiac disease and to them, I say, "Follow your gluten-free diet." For their sake, I am glad that companies like Udi's exist. But current estimates say that only about 1% of the population in the United States actually has Celiac disease. Now, there are also those out there with a gluten sensitivity, for whom eating gluten can cause bloating or discomfort, but they do not have the autoimmune disease. If those people also choose to avoid gluten, more power to them. Even if that brings the total percentage of the United States population who have some sort of problem with gluten to 10%, that's 90% of the population that doesn't have a problem with gluten. So why are we telling everyone to avoid gluten like it is the plague?
I know, I know, it is because wheat is so processed now and natural wheat plants today are different than they were 1,000 years ago and so on and so forth. You know what? Humans are different today than we were 1,000 years ago. So there.
"Well what about GMOs?" you might ask. Recently (i.e. within the last year or so), one of the biggest crusaders against GMOs
gave a talk saying he was wrong all along - that the science to prove the harmful nature of GMOs isn't really there. I'm sure there are those who would say he was coerced into changing his position or whatever, but it does make you wonder. Did he spend the last twenty years only reading studies that supported his theories, and then recently found other studies that opposed his theories? If you can prove anything you want by looking at the results of scientific study through various colored glasses, was his flip a matter of coercion, or changing his glasses?
The simple answer is, "I don't know." I am not a researcher, I am not Mark Lynas, I am not a person suffering from a gluten sensitivity. I am a person who has been living and thriving on a plant-based diet that has included a lot of soy and wheat for almost eleven years. I have just the right balance of good and bad cholesterol in my system. I sometimes get tired when I eat sugary things. I sometimes get gassy when I eat too many beans. But I think it is clear from my outward appearance - my curvy nature, my strong fingernails and hair, my glowing complexion - that I am well-nourished. So I apologize if I am not going to jump on the "say no to soy" bandwagon, the "everything gluten free" bandwagon, or the "drink a glass of wine every day" bandwagon. I am going to eat the foods that make me feel good. I am going to eat the foods that my body tells me it needs, because if I have learned one thing from being vegan, it is that my body knows better than I do what it needs to function properly and it will tell me when something is lacking. And I am also going to allow myself to not be perfect in this regard - I will eat cake every now and again knowing exactly how crappy I will feel afterward.
And my advice to you on your diet? Eat the foods you like. The ones that make your body sing out, "Thank you!" after you have consumed them. The ones that have the carbohydrates, lipids, proteins, vitamins and minerals that support your unique body chemistry. Because you are unique, and you embrace that uniqueness in every other aspect of your life. Embrace it in your dietary choices as well.
Or not. I'm not an expert, so you're free to tell me to go piss up a tree.
