Mortality in vegetarians and non-vegetarians:
A meta-analysis consisting of 7 studies with a total of 124,706 participants from the UK, Germany, USA, Netherlands and Japan was conducted to investigate cardiovascular disease mortality and cancer incidence among vegetarians and non-vegetarians. All-cause mortality, mortality from circulatory diseases, and mortality from cerebrovascular diseases in vegetarians were lower when compared to non-vegetarians by 9%, 16%, and 12%, respectively. Researchers also found a statistically reduced rate for vegetarians in terms of ischemic heart disease mortality (29%) and cancer incidence (18%). This study suggests vegetarians have a mortality advantage compared to non-vegetarians. (30)
