Why is diet a confusing science? It has a lot of different sciences converging onto a single point, which is what you put in your mouth. First, you need some understanding of chemistry, anatomy, biology, sociology, economics, social studies, marketing and branding, consumerism, and even politics. Come to think of it, every aspect of psychology and addiction belongs on the list too.
These are all the topics we have to understand better to truly get to the bottom of why humans still eat poison berries, metaphorically speaking. But one step at a time. First, let us provide you with pure, clean food from plants. Plenty of calories. All the nutrients you need. If it isn't available in the plant kingdom, no matter what anyone tells you, the human body does not need it. Good night.
