Fat dairy products was associated with absence of metabolic syndrome

Scientists on a sample of 147,8 thousands of people from different countries have shown that those people who consume at least two servings of dairy products per day, less often diagnosed with metabolic syndrome compared to those who do not consume dairy products at all. They are also less likely to develop diabetes and hypertension. The relationship, however, is not observed, if a person consumes only low-fat dairy products. Article published in the journal BMJ Open Diabetes Research & Care.

Since dairy products is one of the main sources of saturated fat, they advise not to abuse: for example, in its recent recommendations for a healthy diet the world health organization insisted to prefer a dairy product with low fat content. However, large population studies indicate that consuming dairy products normal fat in sufficient quantities, it is still important — at least for the cardiovascular system.

In turn, one of the major risk factors of developing cardiovascular diseases and obesity and diabetes — the presence of metabolic syndrome. To check, how are the dairy products in the diet and the risk of developing this syndrome, decided scientists under the leadership of Balaji Bavadharini (Bhavadharini Balaji) from McMaster University. For their analysis they used data from a large population study , The Prospective Urban Rural Epidemiological (PURE): the database of this study is updated annually and contains information on life and health of the inhabitants of the 21 countries of Europe, Asia and America (Russia to the list of countries there). At the time of the new study was available information about 147812 men and women aged 35 to 70 years. For each participant of the study was available data that is updated within an average of nine years.

To evaluate the relationship between the consumption of dairy products and metabolic syndrome, the scientists used data on 112992 the participants for whom was the available information about the presence of symptoms: fat accumulation in the abdomen, pressure, and sugar levels, fats and high density lipoproteins in the blood. The authors found that the metabolic syndrome is much less common (p < 0.0001) were found among those who consumed at least two servings of dairy products a day — compared to those who have excluded them from your diet altogether. Important was the fat content of dairy products: established connection was observed among those who favored only low-fat product (although they can be combined with products with normal fat content).

Next, the researchers separately evaluated the effect of diet on risk of diabetes and episodic high blood pressure in the future. Among those participants who consumed at least two servings of dairy products per day (compared to those who did not eat dairy products at all), in the future, rarely diagnosed and diabetes (p = 0.01) and hypertension (p = 0.02). Again, for consumption exclusively low-fat dairy such relationship was not observed.

From the editor

For one serving of a dairy product in this and most other studies are considered, for example, a glass of milk with a volume of 250 ml, one teaspoon of butter or two slices of cheese, 20 grams each. The study also contrasted fat and low-fat dairy products: it is, for example, milk with a classical 3,2–3,6 percent fat and with a fat content of less than 1 percent.
