According tomedia reports, telomeres are a small DNA-protein complex present at the end of the eukaryotic linear chromosome, and the shortening of telomeres is considered a key biological marker of the aging process. A new study examined the relationship between telomere length and milk with different fat concentrations, showing a link between low-fat milk and longer telomeres, which are a few years later than natural aging.
The study was conducted by sports scientists at Brigham Young University, who recruited 5,834 U.S. adults who were divided into different groups and drank different milk. The goal is to explore how milk-eating habits affect telomeres, which become shorter each time they replicate as cells grow.
Almost half of the study participants drank milk every day, while a quarter drank milk at least every week. One-third of the subjects drank full-fat milk, 30 percent drank 2 percent of milk with a fat content, 10 percent at 1 percent of the milk, 17 percent of the participants took skimmed milk, and 13 percent did not consume milk at all.
The researchers examined the telomere lengths of these different groups and were able to identify some obvious links. The most important of these is the overall correlation between high-fat milk consumption and shorter telomeres.
The telomeres of the subjects who drank 2 percent fat milk were 69 base pairs shorter than those who drank milk with 1 percent fat, which the researchers thought was equivalent to four years of aging. At the same time, the telomeres of adults who ate full-fat milk were 145 base pairs shorter than those of adults who ate skimmed milk.
“It’s amazing how big the difference is,” said Larry Tucker, a professor of sports science at Brigham Young University. If you are drinking high-fat milk, be aware that this is expected or related. “
However, correlation does not amount to causation, and the researchers did recognize some of the limitations of their study — for example, people who drank low-fat milk were healthier than those who drank high-fat milk. However, they claim to have taken this and other potential mixing factors into account at the start of the study, and after statistical adjustment, they say the link between the milk fat and telomere length they found had little effect. Howbut, howhes, they also accept that other variables that are not described may be relevant after.
Obviously, more research is needed before the link between cream and telomere length can be explained, but the researchers suggest that eating fat-rich fats, such as those found in high-fat milk, which trigger setypes in the process, can change. Increased intestinal flora and oxidative stress levels may be a cause of this condition.
Interestingly, those who didn’t drink milk at all had shorter telomeres than adults who drank low-fat milk, suggesting that the drink had some anti-aging effect. The researchers say their study adds weight to current Dietary Guidelines for Americans that recommend drinking milk with lower fat content as part of a healthy diet.
“Drinking milk is not a bad thing, ” says Tucker. You should know more about what kind of milk you are drinking. “
