Spanish researchers tracked thousands of participants over roughly five years and found a 30 percent reduction in the rate of heart disease, primarily strokes, among the Mediterranean diet eaters compared with those who consumed more traditional low-fat fare. That diet included more starch and grains, but fewer nuts and oils.
Earlier studies analyzed health outcomes based on participants’ recall of meals and concluded there likely were benefits from a Mediterranean diet.
From the New England Journal of Medicine
A total of 7447 persons were enrolled (age range, 55 to 80 years); 57% were women. The two Mediterranean-diet groups had good adherence to the intervention, according to self-reported intake and biomarker analyses. A primary end-point event occurred in 288 participants. The multivariable-adjusted hazard ratios were 0.70 (95% confidence interval [CI], 0.54 to 0.92) and 0.72 (95% CI, 0.54 to 0.96) for the group assigned to a Mediterranean diet with extra-virgin olive oil (96 events) and the group assigned to a Mediterranean diet with nuts (83 events), respectively, versus the control group (109 events). No diet-related adverse effects were reported.
The folks at the Harvard School of Public Health have been touting the diet for years. More here from them:
The key to this longevity is a diet that successfully resisted the last 50 years of “modernizing” foods and drinks in industrialized countries. These modern trends led to more meat (mostly beef) and other animal products, fewer fresh fruits and vegetables, and more processed convenience foods. Ironically, this diet of “prosperity” was responsible for burgeoning rates of heart disease, obesity, diabetes, and other chronic diseases.
The “poor” diet of the people of the southern Mediterranean, consisting mainly of fruits and vegetables, beans and nuts, healthy grains, fish, olive oil, small amounts of dairy, and red wine, proved to be much more likely to lead to lifelong good health. Other vital elements of the Mediterranean Diet are daily exercise, sharing meals with others, and fostering a deep appreciation for the pleasures of eating healthy and delicious foods.
