Scientists have intensely studied the eating patterns characteristic of the Mediterranean Diet for more than half a century.
Shortly after World War II, Ancel Keys and colleagues (including Paul Dudley White, later President Eisenhower’s heart doctor) organized the remarkable Seven Countries Study to examine the hypothesis that Mediterranean-eating patterns contributed directly to improved health outcomes. This long-running study examined the health of almost thirteen thousand middle-aged men in the United States, Japan, Italy, Greece, the Netherlands, Finland, and then-Yugoslavia.
When the data were examined, it was clear that people who ate a diet where fruits and vegetables, grains, beans, and ﬁsh were the basis of daily meals were healthiest. Topping the chart were residents of Crete. Even after the deprivations of World War II – and in part, perhaps, because of them – the cardiovascular health of Crete residents exceeded that of US residents. Researchers attributed the diﬀerences to diet.
Out of this extensive work came an understanding that certain Mediterranean-eating patterns were remarkably connected with good health. From this conclusion emerged the concept of a “Mediterranean Diet” that could promote lifelong good health.
In subsequent years the body of scientiﬁc evidence supporting the healthfulness of the traditional Mediterranean Diet has continued to grow. Oldways tracks this research and shares it in two ways:
1) Med Diet in the News. We regularly post summaries of the latest research on our Health Studies page. Check there at least once a month, to learn about recent studies.
2) Overview of the Med Diet’s Health Beneﬁts. For those who are new to the health beneﬁts of the Mediterranean Diet, it can be helpful to get the big picture. The following excerpts from a selection of leading medical and health journals demonstrate the enormous amount of evidence supporting the “gold standard” status of traditional Mediterranean eating patterns, which have been shown to:
Greater adherence to a Mediterranean diet is associated with a signiﬁcant improvement in health status, as seen by a signiﬁcant reduction in overall mortality (9%), mortality from cardiovascular diseases (9%), incidence of or mortality from cancer (6%), and incidence of Parkinson’s disease and Alzheimer’s disease (13%). These results seem to be clinically relevant for public health, in particular for encouraging a Mediterranean-like dietary pattern for primary prevention of major chronic diseases.

Adherence to the principles of the traditional Mediterranean diet is likely to be associated with lower overall mortality. Moreover, key features of this diet appear to be transplantable to other dietary cultures and cuisines, and may have a substantial beneﬁcial impact on the general mortality of elderly people who have the Westernized dietary habits. We conclude that a diet that adheres to these principles of the traditional Mediterranean diet is associated with longer survival.

Eating a Mediterranean-style diet rich in olive oil, whole grains, ﬁsh and fruit may protect aging brains from damage associated with cognitive problems. After reviewing brain MRI’s of 712 octogenarians, researchers found that those following the Med Diet the most closely were up to 36% less likely to show brain damage from small strokes.

The Mediterranean diet is not a speciﬁc diet plan or diet program but a collection of eating habits that are traditionally followed by the people of the Mediterranean region. There are at least 16 countries bordering the Mediterranean Sea and food habits vary between these countries according to culture, ethnic background and religion. The Mediterranean diet, containing olive oil, ﬁsh, fruits and vegetables is associated with a low rate of cardiovascular and cancer diseases.

…an optimal diet for the prevention of both coronary heart disease and cancer is likely to extensively overlap with the traditional Mediterranean diet. It is not yet clear which components in the Mediterranean diet are more important for its apparent health eﬀects, but olive oil, plant foods and moderate wine consumption are likely candidates.

The PERDIMED (Prevención con Dieta Mediterránea) study is a multi-center randomized clinical trial to determine the eﬃcacy of the Mediterranean Diet on the primary prevention of cardiovascular disease. 1224 participants already involved in this study were recruited to either consume a Mediterranean diet and either 30g of nuts daily or 1L of olive oil weekly. Individuals who met the criteria for metabolic syndrome at the beginning of the trial showed a decreased prevalence in metabolic syndrome after one year of eating a Mediterranean diet plus 30g of nuts per day. Previous analyses of the data have shown that the Mediterranean diet coupled with nuts protects against oxidative damage and reduces cardiovascular risk factors better than a traditional low-fat diet.

We identiﬁed strong evidence of a causal relationship for protective factors, including intake of vegetables, nuts and monounsaturated fatty acids and Mediterranean, prudent and high-quality dietary patterns. The Mediterranean diet, rich in omega-3 fatty acids, and vitamins C, E and folate, is the only dietary pattern associated with a lower risk for heart disease.

The present study provides a pathophysiologic explanation to the growing scientiﬁc evidence for the beneﬁcial eﬀect of the Mediterranean diet on human health and, especially, atherosclerotic disease. We found that greater adherence to this traditional diet was independently associated with a reduction in the inﬂammation and coagulation indexes that are believed to have an important role in CVD. The World Health Organization reports that the three major components involved in preventing atherosclerotic disease are smoking, physical inactivity, and an unhealthy diet, as they are factors that can be changed. Our ﬁndings emphasize the need for actions from public health care professionals in order to prevent the development and progression of atherosclerotic diseases through the adoption of low animal fat diets, like the Mediterranean diet.

In the Lyon Heart Study, higher ALA [a type of healthy fat] consumption in the context of a Mediterranean diet dramatically reduced total and cardiovascular mortality as well as nonfatal myocardial infarctions. These trials strongly support the protective eﬀects of omega-3 fatty acids, including both ALA and ﬁsh oil, in secondary prevention of CHD. Mediterranean diet enriched with ALA reduced death by more than 70 percent.

In the large prospective cohort of US men, two distinct dietary patterns were identiﬁed using principal component analysis: the prudent [Mediterranean-style] pattern (loaded by a high consumption of fruits, vegetables, ﬁsh and whole grains) and the Western pattern (loaded by a high intake of reﬁned grains, cured and red meats, desserts and sweets and French fries). During 12 years of follow-up, the risk of newly diagnosed chronic obstructive pulmonary disease (COPD) decreased as the prudent [Mediterranean-style] pattern score increased, whereas the risk of newly diagnosed COPD increased as the Western pattern score increased.

Nearly a third of babies born in India are low birth weight (LBW). Researchers followed 676 women there to explore if low seafood consumption is a risk factor for LBW. Women who did not eat ﬁsh during the third trimester had a signiﬁcantly higher risk of LBW. One possible reason for this is the omega-3s fatty acids in ﬁsh may speed up how fast a baby grows by increasing blood ﬂow to the placenta.

Omega-3 fatty acids of marine and plant origin were found to have strong anti-bacterial activity against a range of oral pathogens, according to ﬁndings published in Molecular Oral Microbiology.
EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid) and ALA (alpha-linolenic acid), as well as their fatty acid ethyl esters could inhibit the growth of oral pathogens, including Streptococcus mutans, Candida albicans, and Porphyromonas ginigivalis at relatively low doses.
