Anyone seen the movie Idiocracy? Where in 500 years the whole country is stupid because none of the smart people breed, but the stupid people keep pumpin' kids out? Kind of thought of that, but in this case unhealthy people.
I think this is a possibility though. The dawn of the processed food era brought forth nutrition-void breads and cereals in mass quantities, GMO veggies and grains, infant formulas, canned baby food, factory farmed nutrition-void animal products, and an increased availablility of candies, sugars, and artificial sweeteners.
My parents fed me Gerber, McDonald's, sodas and cereal galore. I'm not particularly short (right between my mom, 5'6" and my dad, 6'1") but I always wonder if such a diet is to blame for my excessive food allergies.
Stumbled into Primal due to food allergies, and subsequent elimination of non-primal foods.
