Any Vegetarians/Vegans here?

[James2014]

Why then does a vegan diet improve health in diabetic patients to a greater extent than a Mediterranean diet(which was varied and not vitamin deficient), as the following study shows?

A couple things on that. First, most people are not diabetic patients. The search for an optimal diet for all is not likely to benefit very much from studying diabetics in my opinion.

Second, humans have some natural resistance to toxins. It's not clear that moderate eat-meating, if it involves intaking some toxins, will affect a person's health or longevity negatively.

I personally suspect that vegetarianism IS healthier than meat-eating. However, the difference in health risks and longevity between moderate meat-eaters and vegetarians is unlikely to be very much-- certainly not strong enough to make a compelling reason for meat-eaters to give up the food they enjoy.

l disagree, diabetes is very common cause of ill health, especially as we age, so anything that improves health in diabetics is likely to improve health overall.

The nurse study l mentioned is also quite illustrative with regards to the effects of even moderate amounts of meat in the diet. The graph below from the paper shows that their is a linear relationship between red meat eating and mortality (hazard ratio).
