Who lives longest: meat eaters or vegetarians?

TheConversation: Our ability to live a long life is influenced by a combination of our genes and our environment. In studies that involve identical twins, scientists have estimated that no more than 30% of this influence comes from our genes, meaning that the largest group of factors that control how long a person lives is their environment. Of the many possible environmental factors, few have been as thoroughly studied or debated as our diet. Calorie restriction, for example, is one area that is being investigated. So far, studies seem to show that restricting calories can increase lifespan, at least in small creatures. But what works for mice doesn’t necessarily work for humans.

JAMA: Fruit and vegetable selections in school meals increased after students had extended exposure to school food made more tasty with the help of a professional chef and after modifications were made to school cafeterias, including signage and more prominent placement of fruits and vegetables, but it was only chef-enhanced meals that also increased consumption, according to an article published online by JAMA Pediatrics.
