vegie diet is good for AF if meat, fish, seafood, etc come with it. otherwise you making your body starve. In orthodox Christianity, there are set of fast when people cannot eat meat, dairy, etc. but the longest is 8 weeks. Sick people and warriors may not follow it.
One doc said that for white people (not hindu) veg diet is worse than smoking.
I know doc who do not want accept AF or Chronic-Fatigue-Syndrome patients if they 're veg. because the doc would not be able to help them.
