How do saturated fats in dairy products affect the heart?
Saturated fatty acids have a bad reputation with most people. They are commonly considered unhealthy. The widespread opinion is that saturated fatty acids increase the risk of cardiovascular diseases. Researchers have now found that saturated fats in yogurt, cheese, butter and milk do not increase this risk.
The University of Texas scientists found in their latest study that consuming saturated fats in yogurt, cheese, butter, and milk does not increase the risk of heart disease. The doctors published the results of their study in the English-language journal "American Journal of Clinical Nutrition".
Does adult fatality increase due to saturated fats?
The results of the study show that - contrary to popular belief - milk fat does not increase the risk of heart disease. The overall mortality of older adults does not increase as a result of consumption, explains study author Dr. Marcia Otto from the University of Texas, Houston.
Fatty acids from dairy products can lower the risk of stroke
The results also suggest that the fatty acid present in dairy products can reduce the risk of death from cardiovascular diseases, especially from a stroke, the expert adds. Milk, yogurt and cheese contain nutrients such as calcium, which lowers blood pressure, and anti-inflammatory fatty acids. Dietary guidelines in the United States and the UK recommend people to choose low or no fat in dairy products. However, the researchers warn that the AL alternatives are often high in sugar, which could drive heart disease.
Current nutritional guidelines should be revised
In line with previous results, the study highlights the need to rethink current nutritional advice for whole-fat dairy products that are rich in nutrients like calcium and potassium, explains Dr. Otto. These are essential for health, not only during childhood, but throughout life. This is particularly true in later years, when malnutrition and diseases such as osteoporosis occur more frequently.
People need to be better informed
Consumers are faced with a lot of different and contradictory information about nutrition, especially with regard to fats, the scientists explain. It is therefore important to have solid studies so that people can make balanced and informed decisions based on scientific facts rather than hearsay.
How was the research carried out?
Researchers from the University of Texas at Houston have medically monitored nearly 3,000 adults over the age of 65 for 22 years. The participants' blood plasma was examined in 1992 to determine various levels of fatty acids. A re-examination was then carried out six years and 13 years later.
Is soy a sensible alternative to cow's milk?
A study published in January found that soy milk is probably the healthiest alternative to cow's milk. When analyzing the four most popular alternatives, it was found that soy has the best nutritional profile due to its high content of anti-cancer compounds known as isoflavones.
Should consumers now prefer to drink almond milk?
Although almond milk is also very trendy and contains healthy fatty acids, which can help with weight loss and cholesterol, according to the doctors, it lacks essential nutrients. Consumers associate these alternatives as a direct replacement for cow's milk, which is not true in all cases, the study authors further explain. (as)
