Why even whole grains are bad. Plus a lot of grains are sprayed with roundup or are GMO.
Some animals are clearly adapted to grain consumption. Birds, rodents, and some insects can deal with the anti-nutrients. Humans, however, cannot. Perhaps if grains represented a significant portion of our ancestral dietary history, things might be a bit different. Some of us can digest dairy, and we’ve got the amylase enzyme present in our saliva to break down starches if need be, but we simply do not have the wiring necessary to mitigate the harmful effects of lectins, gluten, and phytate.
Lectins are bad. They
bind to insulin receptors,
attack the stomach lining of insects,
bind to human intestinal lining, and they
seemingly cause leptin resistance. And
leptin resistance
predicts a “worsening of the features of the metabolic syndrome independently of obesity”. Fun stuff, huh?
Gluten might be even worse. Gluten, found in wheat, rye, and barley, is a composite of the proteins gliadin and glutenin. Around 1% of the population are
celiacs, people who are completely and utterly intolerant of any gluten. In celiacs,
any gluten in the diet can be disastrous. We’re talking compromised calcium and vitamin D3 levels,
hyperparathyroidism, bone defects. Really terrible stuff. And it gets worse: just because you’re not celiac doesn’t mean you aren’t susceptible to the ravages of gluten. As Stephan
highlights, one study
showed that 29% of asymptomatic (read: not celiac) people nonetheless tested positive for anti-gliadin IgA in their stool. Anti-gliadin IgA is an antibody produced by the gut, and it remains there until it’s dispatched to ward off gliadin – a primary component of gluten. Basically, the only reason anti-gliadin IgA ends up in your stool is because your body sensed an impending threat – gluten. If gluten poses no threat, the anti-gliadin IgA stays in your gut. And to think, most Americans eat this stuff on a daily basis.
Phytates are a problem, too, because they
make minerals bio-unavailable (so much for all those healthy vitamins and minerals we need from whole grains!), thus rendering null and void the last, remaining argument for cereal grain consumption.
