A higher concentration of milk fat in the blood lowers the likelihood of developing diabetes. Scientists found that people who consumed products with a high percentage of milk fat had a 46 percent lower risk of developing diabetes compared to test subjects who had a lower percentage of milk fat in their blood.
Almost everyone knows the saying that fat in dishes improves the taste. Researchers from Tuffs University have now found that milk fat can have other positive health effects. People with a higher milk fat percentage in the blood develop diabetes less often. The doctors published the results of their study in the journal "Circulation".
Study examined 3,333 subjects over a period of 15 years
For a long time, nutritionists have recommended low-fat dairy products to improve health and reduce obesity. However, a new study by Tuffs University has now found that this advice does not really make sense. People who eat whole-fat dairy products are less likely to develop diabetes or become obese, the experts say.
The study examined data from 3,333 adults over a 15-year period. The scientists were able to see that people with a lower level of milk fats in their blood have an up to 46 percent higher risk of developing diabetes, says lead author Dr. Dariush Mozaffarian from Tuffs University. Three years ago, a Swedish study had indicated that middle-aged men who consumed high-fat dairy products over a 12-year period were less likely to develop diabetes. Some of the experts suspected that foods with a high fat content satiate longer, which is why we consume fewer sugary calories a day.
Further research is needed to better understand the relationships
How fat helps reduce the risk of diabetes is not fully understood. It may regulate glucose and insulin, doctors say. Milk fat could also act directly on cells related to our muscles and liver. This could improve the ability to remove sugar from food and then process it, the researchers explain. The question now is whether the microbes in certain fat milk products, such as cheese, improve the insulin response and thereby reduce the risk of diabetes.
The results of our study are still preliminary and should not be used as a new basis for nutritional advice, explains Dr. Mozaffarian. However, this current investigation and some older studies may mean that low-fat dairy products are no longer recommended. There is no real evidence that eating low-fat dairy products is healthier than eating products with full-fat milk, experts say. (as)
