Although the Mediterranean Diet is frequently restricted to a few nations in the region, it is important to embrace it fully and sample foods from various cultures. 

The Mediterranean Diet is often praised as the best diet for heart health and reducing the risk of stroke, but it is exclusive to certain countries in the region, namely Greece, Spain, Italy, and France. There are 18 other countries in the Mediterranean region whose foods, flavors, and cultures are rarely included in the diet. The perception of the Mediterranean Diet is that it is focused mainly on the above-mentioned countries. Each culture has its dishes that are cooked differently and offer different nutrients. It is essential to embrace the real Mediterranean Diet in its entirety, explore new spices, flavors, and preparation methods, and enjoy different restaurants that offer unique foods from a variety of cultures.
