It has been the topic of research of scientists for over 50 years. It has been found in many scientific studies that it is one of the healthiest diets in the world. Different statistics of the data of eating habits and their effects on health and longevity collected from the people residing in the Mediterranean countries indicate that the people of the region enjoy the lowest recorded rates of chronic diseases and the highest life expectancy. The characteristics of the Mediterranean diet are as follows –
- It contains an abundance of foods from plant sources, including fruits, vegetables, whole grains, nuts and seeds, which are to be consumed daily.
- It emphasizes on seasonally fresh and locally grown foods. It includes minimally processed foods.
- Olive oil is its principal fat. Its total fat content is less than 25% with saturated fat no more than 7 - 8%.
- It includes daily consumption of low to moderate amounts of cheese and yogurt.
- It includes consumption of low to moderate amounts of fish and poultry twice a week.
- It emphasizes the consumption of lean red meat few times a month.

The diet provides ample nutrients and phyto-nutrients which have benefits ranging from anti-inflammatory, anti-viral, anti-mutagenic, anti-oxidant, anti-thrombotic and vasodilatory effects. The fish in the diet provides two essential fatty acids – omega-3 and omega-4. Over the years, the amount of omega-6 in our diet increased to about 20 times the amount of omega-3, which may be harmful. Mediterranean diet provides sources high in omega-3 fatty acids. The numerous herbs and spices included in the diet have anti-microbial, anti-oxidative, anti-inflammatory, immunomodulatory, anti-diabetic, anti-atherosclerosis, and anti-viral properties.
Health benefits – The Mediterranean offers a large number of health related benefits.

Even though the participants in the Mediterranean groups did not lose weight in the study, they did significantly reduce their risk for heart disease and diabetes.
Reduces cancer – It has been conclusively proven that a traditional Mediterranean diet significantly reduces the incidence of cancers.
