Vegetarian diet has significant environmental effects while decreasing mortality rate.

vegetarian deitThe University School of Public Health has released specifying that a vegetarian diet impacts on the environment while at the same time decreasing the overall human , i.e. increasing longevity. The study focused on of vegetarians, semi-vegetarians and non-vegetarians to quantify and compare greenhouse gas emissions, as well as assessing total mortality.

The population analyzed for this study included over 73,000 people based on the Adventist Health Study, a large-scale study of the nutritional habits and practices of more than 96,000 Seventh-day Adventists throughout the and Canada. The is multi-ethnic and geographically diverse.

The overall findings demonstrated that the for non-vegetarians was 20 percent higher than that for vegetarians and semi-vegetarians. In addition the vegetarian diets resulted in a third less greenhouse gas emissions compared to the non-vegetarian diet.

“The takeaway message is that relatively small reductions in the consumption of animal products result in non-trivial environmental benefits and ,” said Sam Soret, Ph.D., MPH, associate dean at University School of Public Health and co-author of the studies.

The researchers recommend the need to re-assess overall nutritional practices in light of environmental challenges and world wide population growth.
