Nut olive oil has protective effect on cardiovascular disease

Olive oil and nuts are not only indispensable ingredients for making fragrant garlic sauce, but also an important part of healthy diet Recently, researchers completed the first large randomized trial to investigate the protective effect of Mediterranean diet on people without a history of cardiovascular disease In the predicted trial in Spain, the researchers divided 7447 respondents who had cardiovascular risk factors such as type II diabetes, smoking and obesity into three groups: the control group, in which the researchers advised them to eat a low-fat diet, and the other two experimental groups, which were mainly Mediterranean diet containing fish, legumes, vegetables and red wine At the same time, some participants in the Mediterranean diet also received appropriate intake of olive oil (1 liter per week) or nuts (30 grams per day) About four years later, the researchers found that in the Mediterranean diet based group, the number of people who had strokes, heart attacks and died of cardiovascular disease was about 30% lower than in the low-fat diet control group On February 25, researchers published their findings in the New England Journal of medicine Although the idea of the study was to change the participants' overall diet pattern, the researchers also documented important health differences associated with the extra intake of olive oil and nuts by participants in the Mediterranean diet group "Most of the protection in the diet comes from these olive oil and nuts," the researchers said
