That led me to this article about the people of Loma Linda, California -- one of the communities where people live the longest that Dan Buettner talked about in The Blue Zones. There are many similarities between the Adventists' diets and a typical Mediterranean diet and they were the subjects of the study. Admittedly, not a particularly diverse group of subjects, but a large enough study to take note.
"According to a new large study, which will be published in a forthcoming issue of the Journal of Psychosomatic Research, eating Mediterranean foods is linked to feeling happy. People who eat foods associated with a Mediterranean diet -- non-starchy fresh vegetables, fresh fruits, olive oil, legumes, and nuts -- experience more of those emotions associated with being happy than people who eat a typically American diet, which consists of high-fat dairy products, eggs, refined grains, and processed food."Do you feel better when you eat a diet rich in vegetables and fruits, whole grains, beans, nuts and seeds, herbs and spices, and olive oil with occasional dairy, poultry, fish, and red wine?
