I think about how ancient peoples had to find out by trial and error which foods (or which preparation methods) resulted in diets that didn't lead to malnutrition if not outright poisoning. For instance, if your diet depends too much on corn (maize to some parts of the world), you will develop pellagra. the biological cause of which wasn't figured out until the 1930s.
