Chan School of Public Health and Purdue University, who conducted the first meta-analysis of all previously published clinical trials evaluating the effects of red meat on blood lipids.Authors of the study recommend adherence to healthy vegetarian and Mediterranean-style diets, both for their health benefits and also to promote environmental sustainability.
