Surveys were conducted in the last decades of the second world war until today, made on the population of Europe and the United States have shown that longevity is closely related to food and method of cooking.
Namely, it is confirmed that the population living in southern Europe less suffering from cardiovascular disease and a longer life expectancy.
In Western Europe, especially in the USA people usually use fast food (junk food) and caloric foods rich in saturated fat and therefore most susceptible to colon cancer, cholesterol and diabetes.
Unlike western Mediterranean diet rich in many antioxidants (beta-carotene, vitamin E, polyphenols), omega 3, vitamin B-group vitamins and most importantly it is less calories.
The Mediterranean diet consists of lots of vegetables and fruits, many fish (freshly caught wild) that replaces meat, cold pressed olive oil whose main ingredient is oleic acid which is monozasitena and prevents bad cholesterol, then a moderate amount of red wine which with its polyphenols prevents blood clots and reduces the risk of heart attack.
In addition to protecting against cardiovascular disease, it confirmed that the Mediterranean diet has a preventive effect of some other degenerative diseases.
With recent studies of some world-renowned universities, scientists have proven that omega 3 fatty acids are associated with brain health and improve memory in humans.
Mediterranean diet specifically recommended as mandatory for people in old age, because the group of respondents of this age, their memory improved by 19% in just a few years.
