Professor Larry Tucker (Larry Tucker) from the University of Brigham young in the US found that drinking skim milk and milk with low fat content is associated with a slower biological aging in adults.
In the new work, the Professor has studied data obtained through the National study of health and nutrition of the US population (NHANES), which was carried out over several decades.
Tucker analyzed data from almost six thousand people aged 20 to 85 years. He was interested in the relationship between the use of people milk with different fat content and rate of reduction in telomere length.
Explain what telomeres are the end segments of chromosomes that protect DNA from damage during cell division. Over time they get shorter and at some point lose the ability to protect DNA, which in the body begin to occur different kinds of failures and age-related changes.
proven that telomere length — a biological marker of human aging.
Tucker studied sample almost half of the participants had used the milk from the cow daily, and another quarter at least once a week.
Nearly one-third of the volunteers were drinking whole milk (containing 3% fat), another 30% preferred the milk of a fat content of 2%. Meanwhile, 10% of participants consumed 1-percent milk, and another 17% — non-fat (with fat content up to 0.5%). About 13% did not drink cow’s milk at all.
data Analysis showed that people accustomed to drink milk, low fat (1% or less), aging from a biological point of view more slowly than those who drink the milk fat content of 2% and above.
So, volunteers who consumed milk with 2% fat, telomeres were 69 base pairs shorter than those who consumed the milk fat content of 1%. From the point of view of biological aging is equivalent to the difference in more than four years, says Larry Tucker.
meanwhile, people who consumed whole milk, telomeres were 145 pairs of bases.th shorter than the lovers of skim milk.
At this, the more people drank milk with a higher fat content, the shorter were their telomeres.
“it’s Amazing how significant the difference is, says Professor Tucker. — If you are going to drink milk with high fat content, you should know that this could have certain consequences”.
in addition, the scientist found that people who abstained from drinking milk, telomeres were shorter than the lovers of this drink with low fat content.
According to the Professor, the results of his work, presented in the journal Oxidative Medicine and Cellular Longevity, consistent with the recommendation in force in the United States. Experts advise adults wishing to stick to a healthy diet, drink the milk fat content of not more than 1%.
by the Way, earlier “Conduct.Science” (nauka.vesti.ru) wrote about the fact that skim milk helps to cope with depression and also about what milk is best for kids. Also we were told why the use of this product, it is important to know the measure.
