Drinking 1% Rather than 2% Milk Accounts for 4.5 Years of Less Aging in Adults

Arthur T Knackerbracket has found the following story:

[...]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 are the nucleotide endcaps of human chromosomes. They act like 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.

And, apparently, the more high-fat milk people drink, the shorter their telomeres are, according to the new BYU study, published in Oxidative Medicine and Cellular Longevity. The study revealed that for every 1% increase in milk fat consumed (drinking 2% vs. 1% milk), telomeres were 69 base pairs shorter in the adults studied, which translated into more than four years in additional biological aging. When Tucker analyzed the extremes of milk drinkers, adults who consumed whole milk had telomeres that were a striking 145 base pairs shorter than non-fat milk drinkers.

    Where do you think doctors get this shit from. Researchers funded by drug companies.

    And the food industry. The unsaturated fats thing started when the industry tried to push in trans fats, then resisted their removal, then resisted replacing saturated fats with unsaturated, then finally accepted it but tried to push more carbs in.

    But the thing is, for every bad paper, there's a dozen good ones that the regulator ignores and no one mentions. Now at least researchers are required to reveal funding sources in most publications so we're starting to see less and less fake science. Doesn't change the fact the administration simply ignores the science... But still, the science is better at least.

    telomeres are bullshit

    First of all, they're biomarkers, not aging itself. That being said, I think you got your facts critically wrong not reading the next paragraph through:

    When Bailey’s team analyzed the telomeres in Scott’s white blood cells, they found that the average telomere length in these cells actually increased during the mission. “It was exactly the opposite of what we had imagined,” Bailey says. “We proposed that, in fact, because of all the really unique stresses and exposures to things like microgravity, space radiation and isolation … [it] really seemed like they would accelerate telomere loss in space.”

    Once Scott touched back down on Earth, Bailey’s team observed that his average telomere length decreased to roughly match pre-flight levels. In the months following the flight, however, a greater number of telomeres were lost or critically shortened. This could be a concerning finding, as telomere shortening and loss is associated with aging and susceptibility to age-related diseases, including cardiovascular problems and cancer.

    So, the telomeres elongated during spaceflight but shorten back and even further shortened once back on earth for a while eventually being shorter than his brother's. But again, just bio markers. They reflect age over time in the same sense wrinkles can tell how you're aging. Some days will be drier... Sometimes I'll get facial dandruff... Sometimes you'll shine like a 12 year old... Doesn't change the fact they add up, aren't getting fuller and I'm getting old. At least, where gravity is involved...
