The Mediterranean diet is a healthy eating plan based on the traditional cuisine of Mediterranean countries such as Greece, Italy, and Spain. This diet emphasizes vegetables, fruits, whole grains, legumes, nuts, olive oil, and seafood, with moderate amounts of dairy, poultry, and eggs. Other terms used to describe the Mediterranean diet include the Greek diet, the Cretan diet, and the Mediterranean-style diet. These terms all refer to the same dietary pattern that promotes heart health, lowers the risk of chronic diseases, and supports overall well-being. While the Mediterranean diet has been recognized as one of the healthiest diets in the world, it is best to consult with a healthcare professional before making any significant changes to your diet.
