Basic Premise and Various Disclaimers  My overarching theory is
that our bodies and brains do best in conditions for which they
are evolved.  I dig up scientific information and present it in
that context.  I may not be right, and that's okay too. 
However, I feel that by studying evolutionary medicine, we come
closer to the answers for optimal conditions for health and
vitality. The basics of evolutionary medicine are simple:  don't
eat very much fructose, omega-6 rich industrial vegetable oils,
grains (such as wheat, rye, barley, spelt, quinoa, oats, corn,
etc.), or processed "fake" food in general.  Eat as much local,
farmstand, grassfed, pastured, wild-caught as you care for. 
That's vegetables, meat, fish, nuts, eggs, fruits, and high-fat
dairy, red wine, and dark dark chocolate in moderation.  Also,
get plenty of sleep and play.  While a very healthy diet can be
mostly plant-based, I do contend that it is exceedingly
difficult to get by on a strict vegan diet due to lack of B12,
zinc, phospholipids, K2,
