Drinking High-Fat Milk Could Make Your Body Age Faster, Study Finds

Some drinks are as controversial as milk. Here are the devotees, people who swear by 2%, and those who refuse to put anything but whole milk in the cereal. At the top of it, a sea of ​​conflicting studies on the health effects of dairy products adds to the confusion. There is now new research to consider, and it offers compelling evidence for a transition to low-fat milk. This study, led by Larry Tucker, a professor of science at Brigham Young University, found that people who consumed high fat milk showed higher biological aging than those who had low fat or I chose skim milk.

“It was amazing how strong the difference was,” Tucker said in a press release. “If you are going to drink high-fat milk, you should know that doing so is foreseeing some important consequences.”

The study estimates the health statistics of more than 5,800 American adults (representing the entire US population), all drawn from a national health and nutrition testing survey. Respondents answered questions about how often they drank, and how they chose. Almost half of the study participants weaned daily, and another 25% drank at least once a week. The majority of this group drank high fat milk (whole milk or 2%), and about 27 27% chose low fat or skim milk. Tucker also controlled for other health variables such as exercise, age, smoking habits, and protein intake.

To determine the biological age in this group, he focused on telomeres, which are part of the nucleoproteins located at the end of the human chromosome. They help protect and stabilize the chromosomes, and they are also a clear sign of age: each time the cell divides, the telomeres become shorter. As a result, your telomeres gradually shrink as you age. But natural cell copies do not just affect the things that affect them. Diet and lifestyle also play a role. Previous research suggests that eating plenty of fiber, for example, is related to long telomeres and low biological aging.

In this study, Tucker found that milk fat has a strong relationship with telomere length. In particular, the data show that adults who eat whole milk have significantly smaller telomeres than those who skim milk. In addition, for every 1% increase in milk fat (for example, 2% versus one percent milk), telomeres were 69 base pairs less, depending on which cartoon study at the grocery store. Depending on which subjects were selected, the biological age increased by more than four years.

This correlation is established in adults who reported daily or weekly breastfeeding and even when the ticker adjusted to differences in demographic, lifestyle and diet. Interestingly, there was no association between people who rarely sucked, and those who never drank milk had actually actually low telomere who chose low-fat milk (hence Think twice before you leave the dairy). However, for everyone who added milk to their diet, the association was clear.

“The higher the fat fat subjects eat, the lower their telomeres are,” Tucker wrote in the study.

The correlation is compelling, but Tucker warns that the reason for this study is not shown, so it is not certain that milk preferences are behind the changes in telomeres. They speculated that saturated fat, a major component of milk fat, could partially explain the relationship between milk and biological aging. Adults who had elevated levels of saturated fat in their diet showed a strong correlation between telomere length and milk fat content.

Regardless of this, dramatic shrinkage of telomeres should be taken seriously. According to the study, adults who have reduced telomerase also have higher rates of chronic illnesses such as obesity, cancer, depression and heart disease. Among them, longevity is also found below average age. Tucker noted that these results support current dietary guidelines, which encourage low fat milk by 2% and whole milk.

“Breastfeeding is not a bad thing,” Tucker said. “You should be more aware of what kind of milk you are breastfeeding.”
