What if don't drink, don't smoke, do regular exercise, not obese... and eat lots of high quality meat? I haven't seen anything that comes close to showing that this would be unhealthy.
If this is the case, you are also more likely to be financially comfortable as this is an expensive diet. It just isn't possible if you are poor enough, but plenty of vegetarian meals based on beans, rice/grain, and vegetables are.
Why does that matter? If it turns out the worlds healthiest diet is eating the heart of a pure bred Wagyu cow and nothing else, it would still be scientifically useful to know that.
