Researchers have revealed that drinking low-fat milk is significantly associated with less aging in adults.

Published in the 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 per cent and whole) milk.

“It was surprising how strong the difference was, if you’re going to drink high-fat milk, you should be aware that doing so is predictive of or related to some significant consequences,” said study researcher Larry Tucker from Brigham Young University in the US.

For the study, the researchers 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 two per cent vs one per cent 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, the researchers said. And, apparently, the more high-fat milk people drink, the shorter their telomeres are, according to the study.

The study revealed that for every one per cent increase in milk fat consumed (drinking two per cent vs one per cent milk), telomeres were 69 base pairs shorter in the adults studied, which translated into more than four years in additional biological aging. When research team analysed 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.

Nearly half of the people in the study consumed milk daily and another quarter consumed milk at least weekly. Just under a third of the adults reported consuming full-fat (whole) milk and another 30 per cent reported drinking two per cent milk.

Promotional E-Cigarettes Posts on Instagram Outnumber Anti-Vaping Content: Study

E-cigarette popular on Instagram despite anti-vaping content

Promotional e-cigarettes posts on popular photo-sharing platform Instagram outnumber anti-vaping content 10,000 to one, according to a new study and health news.

Despite “The Real Cost” awareness campaign launched by the US Food and Drug Administration (FDA) in 2018, nearly one third of American teenagers are estimated to use e-cigarettes, the researchers said.

The study, published in the journal Frontiers in Communication, highlights the limited impact of the FDA campaign, while also using deep learning – an artificial intelligence method – to better understand the marketing tactics used by vaping companies.

“US public health officials have been calling vaping among youth an epidemic and have been putting a lot of effort into trying to stop this epidemic by introducing #TheRealCost anti-vaping campaign but this stark imbalance in the volume of posts has caused the FDA message to be overwhelmed by marketing from the vaping brands,” said study researcher Julia Vassey from University of California in the US.

Many teenagers continue to view e-cigarettes as healthier than conventional cigarettes, but vaping is associated with inflammation, reduced immune responses and breathing troubles, the study said.

To further understand how vaping is perceived on social media, research team collected 245,894 Instagram posts spanning from before and after the #TheRealCost campaign launch.

The team also conducted interviews with five vaping influencers and eight college-age social media users. “We focused on Instagram because the vaping influencers we interviewed for this study identified Instagram as their most important social media marketing platform,” Vassey explained.

“Based on the results, the FDA anti-vaping campaign is not very popular and we saw Instagram user comments disputing the FDA claims of damaging health effects from nicotine and calling the campaign propaganda,” Vassey added.

In contrast to the FDA’s intentions, the study found that vaping posts received nearly three times more “likes” after the campaign launch. They also found that there were six times as many posts that had greater than 100 likes.

According to the researchers, participants in the focus groups suggested that the anti-vaping campaign promoted scare tactics rather than offering guidance on how to quit vaping. (IANS)
