As four billion years of evolution adapted all creatures to their surroundings, constant high levels of starch and sugar were never encountered. If you analyze anything that might constitute food or nourishment, anywhere in the world, it will be low in starch and sugar. The average starch and sugar content of meat, fish, eggs, insects, plants, fruits, berries, and vegetables is about 4%. Of course, honey and berries are high in sugar. But honey was rarely encountered, and berries are mostly water. Eating berries to satiety actually does not overload metabolism, and even if it does, the berries don’t last but a few days in a primordial setting.
Contrast this 4% starch-sugar content of the primordial world with the average starch-sugar content of dry, expanded pet food, the type bought in the grocery store.
Most all dry pet food is 40% carbohydrate. It should be obvious where this discussion is going; 4% versus 40%.
A single large feeding a day of a diet that is 40% carbohydrate is in drastic conflict with what we have evolved to thrive on, and constitutes literal hormone abuse.
Consider that there are eight hormones that raise blood sugar, yet only one that lowers it. From this, we can conclude that nature saw a great deal of importance to keeping blood sugar held up to a minimum safe level, and relatively little need to lower blood sugar. This one blood lowering hormone, insulin, was invented, so to speak, to capture the rare or occasional spike in blood sugar and save it as fat. In this regard, insulin served a critical role in our evolution, and as we know, insulin is very proficient at this assignment. The hormone insulin is identical, to the last molecule, in all mammals, and does the exact same thing in all creatures.
