Plant-based diets: what should be on the plate?

Abstract
Plant-based foods are common staples of traditional diets in the Mediterranean and Asian regions. These diets, despite different amounts of total fat, include large amounts of fruit, vegetables, legumes, whole grains, and nuts and smaller amounts of red meat and refined grains. It is believed that these traditional plant-based diets have contributed to greater longevity and a lower risk of coronary artery disease (CAD) in the Mediterranean and Asian countries than in Western countries (1).
