Mark Sisson, of www.marksdailyapple.com, recently posted the following on how to respond about your high fat, grain free diet. Mark’s discussion provides a great jumping off point for beginning to understand how your body works and how you can best support it. Enjoy!
“Oh, is that a low-carb thing?”
While grains represent an easy, cheap source of carbohydrates (that most sedentary people simply don’t need), they also contain “anti-nutrients,” proteins and lectins and other nutritional factors that impair digestion, perforate the intestinal lining, increase inflammation, and can even exacerbate or (possibly) induce auto-immune diseases. Since the purpose of life is to reproduce and that grain has to make it into the ground to germinate and turn into a plant, grains don’t want to be eaten, and they use the anti-nutrients to dissuade consumption in lieu of the running, climbing, flying, crawling, biting, and stinging that animals use to survive.
Response: “Kinda, but it’s more than that. In order to survive and spread their genes, a grain uses anti-nutrients to dissuade animals from eating them. Some animals have adapted quite well, but humans haven’t, so I choose not to eat them.”
“I could never give up bread. And aren’t grains the staff of life?”
For the past several thousand years of human history, bread has been a staple food. The ancient Egyptians baked it. The Greeks and Romans made it. You probably grew up with it. It was – and is – cheap and filling. Today, because billions simply need calories from wherever they can get them, grains are the ticket, the “staff of life.” But it’s not like we’ll wither away into nothingness, all because we failed to heed the biological dietary necessity to eat grains ordained by some higher power. Grains aren’t the staff of life in an inherent sense, but rather because they’re cheap, reliable, and easy to work with. They provide calories and a modicum of nutrients to people who absolutely require those calories, regardless of any nutritional downsides. Having joint pain and bloating because you ate some whole wheat, while unpleasant, is better than dying of starvation because you refused it.
Response: “An unfortunately large number of people are forced to subsist on grains as a staple, because they’re cheap and plentiful and calories are scarce, but that doesn’t mean it’s the best way to eat. Grains aren’t necessary if you have access to plenty of fresh animals and plants.”
“Where do you get your fiber?”
As if only cereal grains contain non-starch polysaccharides. As if all the world’s inulin, pectin, chitin, beta-glucans, and oligosaccharides are found solely in wheat, barley, rye, rice, oat, and corn. As if some of the richest sources of soluble fiber – you know, prebiotics, or the kind that our gut bacteria can ferment and convert into metabolically-active short chain fatty acids – aren’t fruits, roots, nuts, and green vegetables. And, as if the richest sources of insoluble fiber – the metabolically-inert stuff that pretty much nothing can digest and which serves only as a bulking agent for improving the robustness of our bowel movements – aren’t whole grains.
Response: “I get my fiber from fruits and vegetables. Best of all, our gut bacteria can actually digest the fiber from fruits and vegetables, thereby producing short chain fatty acids that improve our metabolic health. Grain fiber is just a bulking agent that fills your toilet bowl.”
