Understanding the Mediterranean Diet

A Mediterranean-style diet is a healthy way of eating, not a specific diet to lose weight. It includes a lot of foods from plants, such as vegetables, fruits, beans, nuts, seeds, whole grains, and olive oil. It also includes dairy foods, eggs, fish, and poultry, but in smaller amounts. Fish and poultry are eaten more often than red meat. This diet limits sugar, highly processed foods, refined carbohydrates, and processed meats. Many studies over time have shown health benefits to eating this way. It focuses on making meals with fresh foods that are plant-based and minimally processed.

This plan of eating is inspired by how people eat in countries around the Mediterranean Sea. They include Italy, Greece, Spain, Croatia, Morocco, and Turkey. But it uses foods you can buy in almost any grocery store.
