Drinking low-fat milk such as 1-percent or non-fat may be good for more than just trimming our waistlines.
Researchers have revealed that drinking low-fat milk is significantly associated with less aging in adults.
Published in the journal Oxidative Medicine and Cellular Longevity, the study from Brigham Young University found that people who drink low-fat milk experience several years less biological aging than those who drink high-fat (two percent and whole) milk.
Research on 5,834 U.S. adults by Brigham Young University exercise science professor Larry Tucker, Ph.D., found people who drink low-fat milk experience several years less biological aging than those who drink high-fat (2% and whole) milk.
Tucker investigated the relationship between telomere length and both milk intake frequency (daily drinkers vs. weekly drinkers or less) and milk fat content consumed (whole vs. 2% vs. 1% vs. skim).
Telomeres:- Telomeres are the nucleotide end caps of human chromosomes. They act as a biological clock and they're extremely correlated with age; each time a cell replicates, humans lose a tiny bit of the endcaps. Therefore, the older people get the shorter their telomeres.
They protect the chromosomes from deterioration, and as we become older they become shorter, thereby making us more susceptible to the effects of aging.
Adults who consumed whole milk had telomeres that were a striking 145 base pairs shorter than non-fat milk drinkers, the research revealed. Half the participants in the study consumed milk daily and another quarter consumed milk at least weekly.
Under a third of the adults consumed full-fat (whole) milk and another 30 percent reported drinking two percent milk. About 10 percent consumed one percent milk and another 17 percent drank non-fat milk. Meanwhile, 13 percent did not drink any cow milk.
Though the occasional intake did not seem problematic. Among people who drank milk less than weekly, there was no connection between richer varieties and shorter telomeres.
