In recent years, the Mediterranean diet, as one of the world’s recognized health diet structure, has attracted much attention. More and more evidence shows that adherence to the Mediterranean diet can reduce the risk of diabetes, metabolic syndrome and Alzheimer’s disease. The American Diabetes Association (ADA) and the American Heart Association (AHA) include it in the guidelines for preventing and controlling chronic metabolic diseases such as diabetes, obesity. Studies have shown that for a Predimed study in Spain, the Mediterranean diet (mixed with olive oil and nut foods) has decreased by 53 % in 4 years compared with the control group. However, in the United States, a random test for the Mediterranean diet intervention for type 2 diabetes such as type 2 diabetes.
Recently, researchers from Harvard Medical College have received 25,317 women from Women’s Health Research (WHS), with an average age of 52.9 years. By collecting detailed personal health materials and food frequency questionnaires (FFQS) to discuss and analyze the Mediterranean diet photography The relationship between incidence of diabetes is more important to understand the changes in various logo related to the risk of diabetes.
The Mediterranean dietary intake assessment is based on the insistence of 9 diet. The Mediterranean diet score is 0-3 points, 4-5 points and 6-9 points, and the highest category is 6-9 points. If the intake of the specific diet is greater than fruits, vegetables (excluding potatoes), whole grains, beans, nuts, and monocular and unpopular fatty acids to saturated fatty acids are scored 1 point. For alcohol intake, if the intake is between 5 and 15 g / d, it is given 1 point; for red diet and processing meat intake, if the diet intake is lower than the median research, 1 point is given.
The results showed that after the average follow-up of 19.8 years, compared with 0-3 points, the Mediterranean diet score was reduced by 30 % at the risk of diabetes at 6-9 points 2. Insulin resistance has contributed the greatest contribution to reducing the risk of type 2 diabetes, followed by BMI, high -density lipoprotein measurement and inflammation, branches of amino acids, low density lipoprotein indicators and blood pressure.
It is worth mentioning that there is a strong correlation between high BMI and diabetes. Participants based on BMI value drops are divided into two groups: BMI <25kg/㎡ and BMI ≥ kg/㎡ 25. Among the BMI ≥25 participants, the higher the risk of type 2 diabetes, the lower the risk of the Mediterranean diet, and the biomarker of the Mediterranean diet and type 2 diabetes is similar to the overall result.
In short, the results of the queue research show that a part of the risk of diabetes related to the Mediterranean diet may be mediated by insulin resistance, BMI, lipoprotein metabolism and inflammation. At the same time, among women in BMI ≥25, the intake of the Mediterranean diet is negatively related to the risk of type 2 diabetes.
