what is the healthiest type of food eating eg vegetarian, pescatarian, vegan, meat eater???

Definitely not someone who over-indulges on meat. Depending, of course, on what types of meat; but when you say "meat-eater" I imagine a caveman slurping down bloody cow meat all day. According to Dr. Andrew Weil, and many other nutrition-conscious PHD types, a diet low in animal ingredients is the healthiest one. This, to me, means either pescetarian or vegetarian. Dr. Weil himself was vegan for years, but now is a pescetarian. Hope that helps.

P.S.-Vegan can be incredibly healthy as well - one just has to ensure that they consume a variety of foods, and also take at least some important supplements to guarantee that they intake the necessary kinds of nutrients.  :)

Vegies and meat are a good combination. 

 But more vegies and less meat is the perfect mixture to gain healthy living.
