Scientists Have Determined The Daily Rate Of Dairy Products

A large-scale international study has determined that just two servings of dairy products a day reduce the risk of developing diabetes, hypertension, and metabolic syndrome. The results are published in the journal BMJ Open Diabetes Research & Care.

Earlier studies in North America and Europe have shown that high consumption of dairy products reduces the risk of diabetes, high blood pressure, and metabolic syndrome, a complex of factors that lead to premature death from heart disease. However, scientists did not know whether these results could be distributed to all people on the planet.

The new, largest-ever study involved 147,812 people aged 35 to 70 from 21 countries, including both developed countries such as Sweden and Canada, and developing countries such as Bangladesh, Colombia, Iran, and others.

The participants were monitored for more than nine years. The usual food intake for the previous year was assessed each time by regularly filling out questionnaires that determined the level in the diet of dairy products, such as milk, yogurt, yogurt drinks, cheese, and dishes made from dairy products. Whole-milk and low-fat products with a fat content of one to two percent were taken into account separately. Butter and cream were allocated to a special group because in some countries they are not consumed in food.

Information was also collected about each participant's personal medical history, prescription drug use, educational level, Smoking, and parameters of weight, height, waist circumference, blood pressure, cholesterol, and fasting blood glucose.

The results showed that with an average of two servings of fat dairy products per day, the risk of developing hypertension and diabetes decreased by 11 and 12 percent, respectively. This amount of dairy products is considered optimal by the authors of the study, so the effect of increasing the dose was insignificant — in those who consumed three servings of dairy products per day, this decrease was 13 and 14 percent.

A portion meant: 240 milliliters of milk, about 20 grams of cheese, a package of natural yogurt, 120 grams, or half a Cup of cottage cheese.

The effect of low-fat products was significantly lower, so scientists recommend eating whole, and not skimmed dairy products.

More than 47 thousand of the study participants had not just diabetes or hypertension, but a metabolic syndrome — a combination of factors such as high blood pressure, excess weight, low levels of healthy cholesterol, high blood fat and glucose.

For them, the effect of reducing the risk of developing the disease with daily consumption of dairy products was even higher — from 24 to 28 percent compared to those who did not have these products in their diet.

Scientists note that their research is observational, and does not aim to find out the reasons.

"If our results are confirmed in sufficiently large and long-term trials, increasing dairy consumption may become a feasible and inexpensive approach to reducing metabolic syndrome, hypertension, diabetes, and ultimately heart disease worldwide," the authors write.
