Nutrition may well be one of the most controversial fields of science. It seems like every day brings new information about foods which people thought to be healthy which aren’t, and unhealthy foods which might have benefits after all. In reality, the field is simply dealing with an unfortunate reality. Proper studies of how food relates to people’s health will always take a very long time.
