Dubai, United Arab Emirates (CNN) – New research published in the scientific journal “PLOS Medicine”, which included the world’s largest consumers of dairy products, showed that those who eat more fatty dairy products are less likely to develop cardiovascular disease, compared to For people who consume small amounts.
And the study on the consumption of fatty dairy products, developed by a team of scientists, involved 4,150 people in their 60s in Sweden, which is known to be among the countries with the highest levels in the world in terms of production and consumption of dairy products.
Scientists measured the level of a certain fatty acid in the blood, often found in dairy products, and then experts followed this group for about 16 years, with the goal of finding out how many people had had heart attacks, strokes or any other serious problem. symptoms related to blood circulation and how many people have died.
After statistically adjusting for known risk factors for cardiovascular disease, such as age, income, lifestyle, eating habits, and other illnesses, the researchers found that people with high levels of this acid fat, indicating a high intake of fatty dairy products, were less likely to be at risk for cardiovascular disease.
The team compared the results of the Swedish study after combining them with the results of 17 other studies involving nearly 43,000 people from the United States, Denmark and the United Kingdom.
“Although the results may be influenced in part by factors other than dairy, our study indicates no harm,” said Matti Marklund, principal investigator at the Georges Institute of Public Health in Sydney and co-principal author of the ‘study. A declaration. It is caused by these fats themselves, “adding that” those with a higher percentage of these fats are less likely to develop cardiovascular disease. This link between dairy fat and a lower rate of heart disease is very important, but we need more studies to understand the overall impact of dairy fat on health. »Better milk and dairy products.
Principal author Kathy Trio, a researcher at the Georges Institute, explained that the consumption of certain dairy products, in particular fermented ones, had already been shown to be beneficial for the heart.
Dairy products are rich in nutrients
“A growing body of evidence suggests that the health effect of dairy products is more likely to be related to the type of product, such as cheese, milk, milk and butter, rather than to the content of fat, which has raised doubts about the effectiveness of avoiding dairy fat, “Trio said in a statement. Milk in general is good for the heart and blood vessels.
Trio noted that the study “shows that reducing consumption of fatty dairy products or avoiding dairy products may not be the best option for heart health,” noting that “it is important to remember that dairy products are rich not only in saturated fat but in many other nutrients and in They can be part of a healthy diet. But other fats that you can find in seafood, nuts and non-tropical vegetable oils can have greater health benefits than dairy fat.
Brian Bauer, lecturer in the Department of Health and Nutritional Sciences at the Sligo Institute of Technology in Ireland, Brian Bauer, who was not involved in the research, said the study encourages us to “rethink what we thought we knew about food and disease ”. Dairy products are supposed to be avoided. And this is not discussed properly the more we talk about what we know about healthy eating. “
There is a link, not a causal relation
Alice Lichtenstein, director and chief scientist of the Cardiovascular Nutrition Laboratory at Tufts University, told CNN that she was very concerned about interpreting the study results as suggesting that all dairy products reduce the risk of heart disease. products to reduce the risk of CVD. “
She explained that study data indicated that the group with the highest biomarker for dairy consumption also had a lower body mass index, greater physical activity, lower smoking rate, lower smoking rates, lower rates of type 2 diabetes and cardiovascular disease, in addition to pointing out that her level of education is higher, that she eats more vegetables, fruits and fish and less processed meat … This is considered high quality healthy eating, ”she said, noting that all of these factors lead to a lower risk of cardiovascular disease. sickness.
