Your daily coffee habit may play a role in dementia risk, study finds
NEWYou can now listen to Fox News articles!
Drinking two to three cups of coffee daily could reduce the risk of dementia, according to new observational research published in The Journal of the American Medical Association.
American researchers analyzed four decades of data from more than 130,000 doctors and nurses, finding that moderately caffeinated coffee and tea intake can lower the risk of cognitive decline, according to SWNS.
The analysis revealed that not only did participants with the highest intake of caffeinated coffee have a lower risk of dementia, but there also appeared to be a “sweet spot” where it was most effective.
SCIENTISTS REVEAL THE ONE PRACTICE THAT COULD PREVENT DEMENTIA AS YOU AGE
Previous findings on the relationship between coffee and dementia have been inconsistent due to limited follow-up data. To address this, researchers used information from the Nurses’ Health Study and the Health Professionals Follow-Up Study, tracking healthcare professionals from midlife through older age.
Over a follow-up period of up to 43 years, the team analyzed self-reported dietary patterns collected through questionnaires administered every four years.

By adjusting for variables such as smoking, physical activity and underlying health conditions, the researchers were able to isolate the specific relationship between caffeine intake and long-term brain health, SWNS noted.
Of the 131,821 participants involved in the long-term analysis, 11,033 developed dementia.

The analysis revealed that participants with the highest intake of caffeinated coffee had an 18% lower risk of dementia compared with those who reported little or no consumption.
These participants also performed better on tests of overall cognitive function, the report noted. While higher tea intake yielded similar results, decaffeinated coffee did not, suggesting that caffeine is likely the driving neuroprotective factor.
The cognitive benefits were most pronounced in those who consumed two to three cups of caffeinated coffee or one to two cups of tea daily.

Dementia affects more than six million Americans and 55 million people worldwide, with the National Institutes of Health reporting more than 100,000 U.S. deaths annually.
Experts emphasize that early prevention is crucial, as current treatments offer only modest benefits once symptoms appear. This has led scientists to investigate the role that specific lifestyle factors play in cognitive decline.

“When searching for possible dementia prevention tools, we thought something as prevalent as coffee may be a promising dietary intervention,” senior study author Daniel Wang, an assistant professor at Harvard Medical School, noted in a press release from SWNS.

Both coffee and tea contain bioactive ingredients such as polyphenols and caffeine, which may reduce inflammation and cellular damage while defending against cognitive decline. Researchers referred to these properties as “neuroprotective.”

Contrary to some previous studies, higher caffeine intake did not produce negative effects; instead, it provided consistent neuroprotective benefits even for those with a high genetic predisposition to the disease, per SWNS.
Despite the encouraging findings, Wang cautioned that the effect size is small and should be viewed as just one of many ways to protect cognitive health during aging.

Experts reveal why ‘nonnamaxxing’ trend may improve mental, physical health
NEWYou can now listen to Fox News articles!
The key to feeling better in a fast, overstimulated world might be surprisingly simple: Live a little more like your grandparents.
A growing social media trend, dubbed “nonnamaxxing,” draws inspiration from the slower, more intentional rhythms associated with an Italian grandmother.
The lifestyle is often linked to activities like preparing home-cooked meals, spending time outdoors and making meaningful connections.

“Nonnamaxxing is a 2026 trend that embraces the slower, more intentional lifestyle of an Italian grandmother (a Nonna). Think cooking from scratch, long family meals, daily walks, gardening and less screen time,” Erin Palinski-Wade, a New Jersey-based registered dietitian, told Fox News Digital.

Stepping away from screens and toward real-world interaction can have measurable benefits, according to California-based psychotherapist Laurie Singer.
“We know that interacting with others in person, rather than spending time on screens, significantly improves mental health,” she told Fox News Digital, adding that social media often fuels comparison and lowers self-esteem.
LONELINESS MAY BE SILENTLY ERODING YOUR MEMORY, NEW RESEARCH REVEALS
Living more like previous generations isn’t purely driven by nostalgia. Cooking meals from scratch, for example, has been linked to better nutrition and more mindful eating patterns.
Adopting traditional mealtime habits can improve diet quality and support both physical and mental health, especially when meals are shared regularly with others, Palinski-Wade noted.

There’s also a psychological benefit to slowing down and focusing on one task at a time. Anxiety often stems from unfinished or avoided tasks, Singer noted, and engaging in hands-on activities can counteract that.

“Nonnamaxxing encourages us to be present around a task, like gardening, baking or knitting, or just taking a mindful walk, that delivers something ‘real,’” she said.

Palinski-Wade cautions against turning the trend into another source of pressure, noting that a traditional “nonna” lifestyle often assumes a different pace of life.
The key, she said, is adapting the mindset, not replicating it perfectly.

Singer added, “Having a positive place to escape to, through whatever activities speak to us and make us happy, isn’t generational – it’s human.”

Loneliness may be silently eroding your memory, new research reveals
NEWYou can now listen to Fox News articles!
Feeling lonely may take a toll on older adults’ memory — but it may not speed up cognitive decline, according to a new study.
Researchers from Colombia, Spain and Sweden analyzed data from more than 10,000 adults ages 65 to 94 across 12 European countries and found those who reported higher levels of loneliness did worse on memory tests at the start of the study, according to research published this month in the journal Aging & Mental Health.
Over a seven-year period, however, memory decline occurred at a similar rate regardless of how lonely participants felt.

“The finding that loneliness significantly impacted memory, but not the speed of decline in memory over time was a surprising outcome,” lead author Dr. Luis Carlos Venegas-Sanabria of the School of Medicine and Health Sciences at the Universidad del Rosario said in a statement.

“It suggests that loneliness may play a more prominent role in the initial state of memory than in its progressive decline,” Venegas-Sanabria said, adding that the findings highlight the importance of addressing loneliness as a factor in cognitive performance.
The findings add to debate about whether loneliness contributes to dementia risk. While loneliness and social isolation are often considered risk factors for cognitive decline, research results have been mixed.
EXPERTS REVEAL HIDDEN LINK BETWEEN POOR SLEEP AND ALZHEIMER’S DISEASE RISK
The study looked at data from the long-running Survey of Health, Ageing and Retirement in Europe (SHARE), which tracked 10,217 older adults between 2012 and 2019. Participants were asked to recall words immediately and after a delay to measure memory performance.

Loneliness was assessed using three questions about how often participants felt isolated, left out or lacking companionship.
About 8% of participants reported high levels of loneliness at the outset. That group tended to be older, more likely to be female and more likely to have conditions such as depression.
DEMENTIA RISK SIGNALS COULD LIE IN SIMPLE BLOOD PRESSURE READINGS, SAY RESEARCHERS
Researchers found that those with higher loneliness had lower scores on both immediate and delayed memory tests at baseline. Still, all groups — regardless of loneliness level — experienced similar declines in memory over time.
The results suggest loneliness may not directly accelerate the progression of memory loss, though it remains linked to poorer cognitive performance overall.

Experts warn, however, that the findings should not be interpreted to mean loneliness is harmless.
“The finding that lonely older adults start with worse memory but don’t decline faster is actually the most interesting part of the paper, and I think it’s easy to misread,” said Jordan Weiss, Ph.D., a scientific advisor and aging expert at Assisted Living Magazine and a professor at NYU Grossman School of Medicine.
“It likely means loneliness does its damage earlier in life, well before people show up in a study like this at 65-plus,” Weiss told Fox News Digital.
By older age, long-term social patterns may already be established, making it harder to detect when the effects of loneliness first took hold, an aging expert says. (iStock)

“By the time you’re measuring someone in their late 60s, decades of social connection patterns are already baked in,” he said.
Weiss, who was not involved in the research, added that loneliness may coincide with other health conditions, and noted that participants who felt more isolated also had higher rates of depression, high-blood pressure and diabetes. The link, he said, may reflect a cluster of health risks rather than a direct cause.
“While they can go hand-in-hand, it’s not clear that loneliness contributes to dementia,” a psychotherapist says. (iStock)
Amy Morin, a Florida-based psychotherapist and author, said the findings reflect a broader pattern in research on loneliness and brain health, and that the relationship may be more complex than it appears.

“The evidence shows there’s a link between loneliness and cognitive decline but there’s no direct evidence of a cause and effect relationship,” she said. “So while they can go hand-in-hand, it’s not clear that loneliness contributes to dementia.”
Morin added that loneliness, which can fluctuate, may not be the root of the problem, but rather a symptom of other underlying mental or physical health issues.

“It’s important to be proactive about social activities,” Morin said. “Joining a book club, having coffee with a friend, or attending faith-based services can be a powerful way to maintain connections in older age.”
