You’ve heard me mention the “Paleolithic diet”, characterized by consumption of fruits, veggies and protein (fish, poultry, tofu, lean meat) and minimal consumption of grains, corn, and cereals. Its called “Paleolithic” because it is the foods our ancestors ate throughout most of our history and presumably the foods we evolved to be able to utilize the most efficiently.
It is only in the last 10,000 years or so that we have changed from strictly hunter gatherers and turned to agriculture as a major source of our caloric intake and with that, increased consumption of grains and the like.
As a species, though, we haven’t had enough time to evolve the digestive system to efficiently use these; evolution works really slowly!
Let’s look at what happens when you eat, say, a bowl of microwave popcorn. These types of high glycemic carbohydrate foods, which tend to be milled or processed before consumption (which speeds their digestion), get very quickly absorbed in the digestive tract as sugar.
