Daily coffee drinking linked to major health benefit in women as they age, study finds
NEWYou can now listen to Fox News articles!
A popular morning beverage could do more than provide a perk. It could also help women stay healthy as they age.
That’s according to new research from Harvard University, which followed a group of nearly 50,000 women from the Nurses’ Health Study for a 30-year period.
The researchers found that drinking coffee every morning could help women stay mentally sharp and physically strong later in life, according to a press release from the American Society of Nutrition.
THE OPTIMAL TIME TO DRINK COFFEE ISN’T WHEN YOU NORMALLY HAVE IT
The benefits were seen in middle-aged women who drank caffeinated coffee. Decaf coffee and tea did not have the same effect.
“‘Healthy aging’ here meant surviving to older age without major chronic diseases and with good physical, mental and cognitive function,” Sara Mahdavi, Ph.D., a post-doctoral fellow at Harvard T.H. Chan School of Public Health, Harvard University, told Fox News Digital.

“Importantly, this relationship persisted even after accounting for key lifestyle factors like diet quality, physical activity and smoking — each of which are also strongly associated with healthy aging in their own right.”
The women who qualified as “healthy agers” were found to consume an average of 315 mg of caffeine daily, primarily via coffee-drinking.

Each additional cup of coffee was linked to a 2% to 5% greater chance of healthier aging, the study found.
Although soda also contains caffeine, people who drank it every day were shown to have a 20% to 26% reduced chance of healthy aging.

“The health benefits appeared specific to coffee, rather than caffeine more broadly,” Mahdavi noted.
“We didn’t see the same associations with decaf coffee, tea or caffeinated soda — suggesting that coffee’s unique combination of bioactive compounds may play a key role.”
The findings were set to be presented on Monday at NUTRITION 2025, the annual meeting of the American Society for Nutrition held in Orlando.
WOMEN MAY HEAR BETTER THAN MEN, NEW STUDY SUGGESTS
“While past studies have linked coffee to individual health outcomes, our study is the first to assess coffee’s impact across multiple domains of aging over three decades,” said Mahdavi.
“The findings suggest that caffeinated coffee … may uniquely support aging trajectories that preserve both mental and physical function.”
“The health benefits appeared specific to coffee, rather than caffeine more broadly.”
The researcher acknowledged that the study has some limitations.
“As with all observational studies, we cannot establish causality,” she told Fox News Digital. “While we adjusted for many factors, unmeasured confounding is always possible.”

Mahdavi also pointed out that the study group mostly included white, educated female health professionals.
“Further work is needed to confirm generalizability to broader populations.”
“Moderate coffee intake may offer some protective benefits when combined with other healthy behaviors, such as regular exercise, a healthy diet and avoiding smoking.” (iStock)
Coffee’s benefits are “relatively modest” compared to the benefits of overall healthy lifestyle habits, according to the researcher.
“These results, while preliminary, suggest that small, consistent habits can shape long‑term health,” said Mahdavi. “Moderate coffee intake may offer some protective benefits when combined with other healthy behaviors, such as regular exercise, a healthy diet and avoiding smoking.”
“We don’t recommend starting coffee if you don’t already drink it or if you’re sensitive to caffeine,” she went on.
“But for people who already consume moderate amounts — typically two to four cups per day — this study adds to the evidence that coffee can be part of a healthy lifestyle.”
“The findings suggest that caffeinated coffee … may uniquely support aging trajectories that preserve both mental and physical function,” the researcher said. (iStock)
Mahdavi emphasized, however, that nutrition, regular exercise and not smoking are the “most powerful and proven contributors” to healthy aging.
The team is now planning to explore how coffee’s bioactive compounds — particularly polyphenols and antioxidants — might influence molecular aging pathways, including inflammation, metabolism and vascular health, Mahdavi said.

One walking habit could signal a healthier brain after 80, scientists say
NEWYou can now listen to Fox News articles!
Older adults identified as “super movers” are about half as likely to develop cognitive impairment than their peers.
That’s according to a recent study led by Stony Brook Medicine in New York, which evaluated the cognitive function of 4,000 adults 80 and over who participated in multiple aging and longevity studies over several years.
Among this group, 6% to 10% were classified as super movers, which means they walk at a much faster pace than others of the same age and gender — at speeds comparable to people three decades younger.
COMMON VITAMIN MAY INFLUENCE BRAIN AGING IN WAYS SCIENTISTS DIDN’T EXPECT
The super movers were found to have about half the risk of cognitive decline compared to seniors with typical gait speed.
The findings were published in the journal Neurology on June 16.

“The study reinforces that mobility and brain health are closely connected,” lead study author Dr. Joe Verghese, MD, neurologist at Stony Brook Medicine, told Fox News Digital. “This suggests that preserving mobility may be an important marker of healthy brain aging and resilience.”
‘LONGEVITY GENE’ MAY PROTECT THE BRAIN FROM ALZHEIMER’S BY BOOSTING DNA REPAIR, STUDY FINDS
The most intriguing finding, according to Verghese, was that super movers maintained cognitive function despite having similar dementia-related brain changes as their peers.
In postmortem brain analysis, there was no difference in dementia-related pathologies between the super movers and the slower walkers, the study stated.

“This suggests they may possess resilience mechanisms that help preserve brain function even in the presence of age-related changes,” he said. “Understanding these resilience factors could lead to new strategies for promoting healthy brain aging.”
As the study was observational, there were some limitations, and it does not prove that walking faster prevents dementia, the researchers noted.

“Other factors, such as cardiovascular health, physical fitness or genetics, may also contribute to both faster walking and better cognitive outcomes,” Verghese said.

This study adds to growing evidence that what’s good for the heart and muscles also benefits the brain, he noted, adding that “staying physically active remains one of the most effective, evidence-based ways to support healthy aging.”
“Walking speed is best viewed as a marker of overall health, not a treatment.”
“The broader message is that physical activity is important at any age,” Verghese said. “Walking is an easy step-up point because you don’t need any special equipment. You can do it inside or outdoors, and you can do it on a regular basis. You can walk with a dog, you can walk with a friend.”
Any activity is beneficial if it’s done regularly and with the right intensity, he added.

Rather than just trying to walk faster, the neurologist recommends that seniors focus on maintaining mobility through regular physical activity, strength training, balance exercises and good cardiovascular health.
“Walking speed is best viewed as a marker of overall health, not a treatment,” Verghese noted.
Major public health guidelines from the CDC and U.S. Physical Activity Guidelines recommend at least 150 minutes of moderate-intensity aerobic activity each week, such as brisk walking.

This can be achieved by walking 30 minutes a day, five days a week, or about 20 to 25 minutes most days. Another option is to engage in shorter sessions that add up over the day.

“You have to do it within your health limitations and medical conditions,” Verghese advised. “So if there are any medical concerns, I would get your physician to clear you before starting exercise.” The good thing about walking, he added, is that you can start at a slow pace and then gradually build up to a brisker pace.
“And then adding on strength and balance training, whatever age you are, I think is also important.”

Dr Oz warns Medicare scammers are stealing billions — and your personal information could be next
NEWYou can now listen to Fox News articles!
Washington, D.C. – Medicare fraud is a multibillion-dollar problem that government officials say threatens both taxpayer dollars and Americans’ personal identities.
In a July 6 interview with Fox News Digital at the Great American State Fair in Washington, D.C., Dr. Mehmet Oz warned that every dollar stolen through Medicare fraud is a dollar taxpayers lose – a problem that has worsened since the COVID pandemic.
“If I had to just pick one thing to focus on to make healthcare more affordable in America, I’d go to health fraud and all the waste and abuse that accompanies it,” said Oz, who is the administrator of the Centers for Medicare & Medicaid Services. “And just to put this in perspective, we think it’s about $100 billion a year.”

Medicare fraud can include billing for services that were never provided, overcharging for medical equipment, using stolen patient or doctor information, or performing unnecessary procedures, according to the U.S. Government Accountability Office.

As the Trump administration ramped up efforts to combat fraud, CMS reported $41.9 billion in Medicare program integrity savings in 2025, up 59% from $26.3 billion in 2024.

Medicare fraud not only harms the federal budget and steals from taxpayers, but exposes seniors to identity theft, unnecessary care, higher premiums and reduced access, Oz cautioned.

Removing corruption from the healthcare system will have the greatest impact among seniors, since “so much of the fraud is perpetrated against them,” the administrator said.
“I’m talking about people tricking seniors to give up their Medicare beneficiary numbers, which is like a credit card basically,” he said. “These scammers can take those numbers and use them for all kinds of illegitimate purposes.”

“People are stealing from you by pretending to send you drugs you don’t want, wheelchairs you don’t need, [and] services you never asked for or don’t benefit from,” Oz added.
To prevent this, he shared his top advice for seniors: Do not give your Medicare beneficiary number to anybody, do not answer questions on a phone call from an unknown person and do not give away personal information.

“These scammers are calling seniors, tricking them, and once they have key information, they can steal it,” he said. “And I won’t know it and you won’t know it.”
“We want to protect people who need these programs the most,” Oz went on. “You do that by making sure scoundrels don’t corrupt the systems and steal money out of the till that is designed to help folks in dire straits when they’re vulnerable and in need of services.”
Seniors should never share their Medicare information with unknown people, the administrator advised. (iStock)
Removing fraud could “double the life expectancy of the trust fund that makes all this possible,” Oz predicted.
“If you’re worried about Medicare being there when you’re ready to retire in a couple decades, depending on how old you are, and you’re concerned that it might not last because of all the fraud that’s hitting it … you’ve got a good [reason to] worry,” he said.
