If people ate real food, their tastes would change and sweet stuff would be far less appetizing to them.
Our tastes are corrupted by a high salt and high sugar diet from a very young age.
That is true. I worked with a lot of immigrants who could not take the sweetness of Cola. They had such good diets of real food, they couldn’t take sweets. The wildest they got with beverages was unsweetened ice tea.
I had a prolonged sickness where I didn’t eat much over two weeks time. I felt better and had an apple. It was the best tasting apple I ever had, not because it was so good but because my taste buds had recalibrated back to a more normal state from the rich food I usually ate and so became accustomed to.
