Why is that? Carbohydrates do not provide any nutrition that cannot be found in nutrient dense food sources. All human bodies need glucose, but to say that glucose must come from dietary carbohydrate is simply incorrect. The liver can produce all the glucose required by the body from protein and fat (glycerol molecules, actually). This process is known as gluconeogenesis.
The consumption of dietary carbohydrate provides excess glucose to the human body. Excess glucose in the bloodstream will literally poison the body over time, so the body must reduce the elevated levels of glucose. The first way to get them out of the blood is to burn them for energy. That is where the misconception of "needing carbs as a primary energy source" comes from. The excess that is left over must then be moved into storage (fat cells), this is accomplished by the release of insulin. Excess consumption of dietary carbohydrate stimulates excess production of insulin. Over time, this puts a lot of stress on the pancreas, and eventually the amount of insulin secreted in proportion to blood glucose becomes less effective, causing more insulin to be pumped out to do the same work (insulin resistance). This can go on for years until the pancreas declines and ceases to function, developing into full blown insulin dependent T2 diabetes.
By raising kids on a diet loaded in carbs (like the traditional SAD), we are setting them up for a future of metabolic disorders. It's not our fault entirely, it's what our governments have been teaching us for the last several decades. Looking at it from a TF standpoint, in most cultures still living traditionally without the high carb fare that we relish in our modern society, cardiovascular disease and metabolic disorders such as diabetes and obesity are unheard of. FWIW, humans did not evolve on grains and sugars, but we are a very hardy creature that can survive many abuses. Improper nourishment prevents us from thriving and causes slow physical degeneration.
I am in no way launching an attack on the PP, just taking an opportunity to educate
