An interesting transition on the perception of what is healthy seems to have been made in the 20th and 21st centuries where we are now favoring pills over real food. Why? I believe that with the advent and advances in pharmaceuticals where some pills have saved or prolonged lives, we are now prone to view pills, liquids, or other substances that are not whole foods as keys to health. This includes supplements, as we no longer understand the critical health contributions of a diet of whole, unprocessed foods. We're looking for the easy button in pills and other supplements. The marketing of these products is simply reinforcing this perception.
