Consuming dairy products such as milk and cheese could reduce the risk of heart disease and stroke, according to a study that challenged the popular belief that dairy products are harmful.
Marcia Otto, lead author of the study and assistant professor of epidemiology, human genetics and environmental science at the UTHealth School of Public Health, said in a statement: "Our results not only support, but also strengthen evidence that suggests that milk fat, contrary to popular belief, does not increase the risk of heart disease or overall mortality in older adults. "
A Fatty Acid Present in dairy products has actually reduced the risk of death from cardiovascular disease, especially stroke, she said.
The results come from the decline in US milk sales of 11% between 2015 and 2020, according to forecaster forecasts Mintel At the same time, alternatives to milk, such as soybean and almond, have gained popularity, with sales increasing by more than 61 percent over the last five years.
Consumers They have been confronted with diverging information, especially with regard to fats, "said Otto. "It is therefore important to have solid studies so that people can make more balanced and informed choices based on scientific facts rather than hearsay."
To reach their conclusion, the researchers evaluated 3,000 adults aged 65 and over. At the beginning of the study in 1992, levels of three different fatty acids found in dairy products were measured in their blood, and again six and 13 years later.

And one was linked to a lower risk of dying from cardiovascular disease. In addition, people with higher levels of fatty acids, which researchers believe they could derive from their consumption of dairy products, have a 42 percent lower risk of dying from a stroke.
Otto argued that the current dietary recommendations on whole dairy products should be revisited as many are a rich source of nutrients, such as calcium and potassium
"They are essential for health not only during the day. childhood but also throughout life In years later, when under-nutrition and conditions such as osteoporosis are more common, "
Research published in American Journal of Clinical Nutrition, was funded by the National Institutes of Health.
This study contrasts with the most recent dietary guidelines for Americans, which recommend the consumption of fat-free or low-fat dairy products, such as milk, cheese, yogurt, and fortified soy beverages. . Otto, however, pointed out that low-fat dairy products can be misleading in their health promises, as they may contain high levels of added sugars, which have already been linked to cardiovascular disease and the disease. obesity
The problems are particularly important because heart disease is the leading cause of death in the United States, claiming 610,000 lives each year. Stroke is the fifth largest killer, with 795,000 people in the United States who experience it every year.
A 2017 study also found that consuming whole milk products does not seem to increase the risk of heart attack or stroke. , published in European Journal of Epidemiology included a meta-analysis of 29 studies and indicated that products such as cheese, milk and yogurt had a "neutral" effect on health.
