- Eating at least two daily servings of dairy is associated with lower risks of diabetes and high blood pressure, as well as a group of factors that increase the risk of cardiovascular disease (metabolic syndrome).
–
The observed associations were stronger for full-fat dairy products, indicated the findings of the study, conducted by Dr. Andrew Mente of the Institute for Population Health Research, Hamilton Health Sciences and McMaster University in Canada.
Previous research has suggested that a higher dairy intake is associated with a lower risk of diabetes, high blood pressure, and metabolic syndrome. But these studies have tended to focus on North America and Europe, excluding other regions of the world.
To see if these associations can also be found in a broader range of countries, the researchers turned to people who participated in the Urban Rural Epidemiology Prospective (PURE) study, Population Health Research Institute, Hamilton Health Sciences and McMaster University, Hamilton, Ontario, Canada.
All the participants were between 35 and 70 years old and came from 21 countries: Argentina, Bangladesh, Brazil, Canada, Chile, China, Colombia, India, Iran, Malaysia, Palestine, Pakistan, the Philippines, Poland, South Africa, Saudi Arabia, Sweden, Tanzania, Turkey, the United Arab Emirates and Zimbabwe.
The usual dietary intake during the previous 12 months it was evaluated using food frequency questionnaires. Dairy products included milk, yogurt, yogurt drinks, cheese, and dishes made with dairy products, and were classified as full or low fat (1-2%). Butter and cream were evaluated separately as they are not commonly eaten in some of the countries studied.
Information was also collected on personal medical history, prescription drug use, educational level, smoking, and measurements of weight, height, waist circumference, blood pressure, and fasting blood glucose.
Data on the five components of metabolic syndrome were available for almost 113,000 people: blood pressure above 130/85 mm Hg; waist circumference above 80 cm; low levels of high-density (beneficial) cholesterol (less than 1-1.3 mmol / l); fats in the blood (triglycerides) of more than 1.7 mmol / dl; and fasting blood glucose of 5.5 mmol / l or more. Total average daily dairy consumption It was 179 grams. Some 46,667 people had metabolic syndrome, defined as having at least 3 of the 5 components.
Total dairy and whole dairy, but not low-fat dairy, were associated with a lower prevalence of most components of metabolic syndrome, with the largest association size in those countries with normally low dairy intakes.
At least 2 servings a dairy day Totals were associated with a 24% lower risk of metabolic syndrome, increasing to 28% for full-fat dairy products alone, compared to daily dairy intake.
The health of nearly 190,000 participants was followed for an average of nine years, during which 13,640 people developed high blood pressure and 5,351 developed diabetes.
At least 2 servings a day of total dairy products it was associated with an 11-12% lower risk of both conditions, increasing to a 13-14% lower risk for 3 daily servings. The associations were stronger for full fat than for low fat dairy.
This is an observational study, and as such cannot establish the cause. However, the researchers suggest that “if the findings are confirmed in large enough, long-term trials, increased dairy consumption may represent a feasible and low-cost approach to reduce metabolic syndrome, hypertension, diabetes and, in Ultimately, cardiovascular disease events worldwide. “
