Until about 12,000 years ago, our ancestors were hunter-gatherers. We lived in small tribes, working together and sharing most everything. We followed the animal herds in their seasonal migrations and when there was a drought, we had to pick up and move to better conditions. And we had to be able to endure times of scarcity. So we ate when we could (with no portion control) and took advantage of our life-saving ability to convert plant carbohydrate and animal protein into simple sugar, which we stored as fat. And the reason we could do this was the powerful hormone Insulin.
Without this ability to store fat, we would not have survived. At some point the herds of animals we ate diminished and we had to forage for plants to survive. So somewhere around 12,000 years ago, someone figured out how to grind up wild grass, an ancestor of wheat, and make it digestible to humans who don’t have two stomachs. This development of agriculture came with advantages and problems. We started to multiply more than ever before and had to develop government in order to oversee the growing, the distribution and the processing of the wheat. This is where civilization began and how humans thrived.
But as we changed what we ate, diseases started to develop . This was because we had not adapted to eating these high-starch foods. As we started cultivating more plants and breeding in those traits we preferred, we made fruits and vegetables bigger, juicier and sweeter. That’s because we were still driven, on a molecular level, to seek those foods that could be converted into life-saving fat – specifically Carbohydrates!
