"A number of studies have shown that a diet low in meat is linked to longer lifespans. But the matter is far from settled, as some studies haven’t found a significant difference in life expectancy between meat eaters and vegetarians.
"But there is growing evidence that plant-based diets are associated with benefits like lower blood pressure, cholesterol, blood sugar and reduced body weight. These improved health measures often translate to less risk of heart disease, diabetes, cancer and other diseases. Eating more whole, plant-based foods could help lower the risk of some health conditions, and might even help people live longer. But researchers also suspect that vegetarians are more health-conscious overall — so, they’re likely to be drinking and smoking less and moving their bodies more than the general population — which complicates some study results.
"Still, emerging research points to a potentially helpful role of plant-based diets in managing some chronic health conditions. For instance, some studies suggest that plant-based diets — veganism in particular — may help control rheumatoid arthritis."
