Nutrition is tough thing to research fr a person. No matter what you look for, you can find places that tell you it's great and you should be eating it, and other places that tell you it's bad and you should never eat it.
Same thing with veganism, vegetarian, meat/animal products heavy, organic....GMO/non GMO.... you can find any number of places online that tell you how great they are and how bad they are.
Plus, how does a person use the info that all these studies give us? I can't sit through 60 pages of findings and read science-ese to come to my own conclusions.
