I actually don't eat many grains and haven't for about a year and a half as per Dr. Fuhrman's recommendations. I am thinking about bringing some more such as quinoa, wild rice and other pseudograins into my diet.
I saw a youtube of Fuhrman explaining that he doesn't have a problem with grains, he just recommends that people trying to lose weight not eat them because they are a significant calorie source.
As a vegan, there are some amino acids you just aren't going to get in significant quantities unless you eat whole grains. Your body has some capacity to deal with that, but since this is a body building forum Im guessing people are out for *optimal* nutrition, health, and development.......so....I am mentioning it.
