Drinking coffee daily tied to healthy aging among women, study finds

(NEXSTAR) – A study presented at the American Society for Nutrition Monday suggests that an eye-opening cup of java may also have long-term health benefits for women. 'Our study has several key strengths,' said Sara Mahdavi, lead researcher and an adjunct professor at the University of Toronto, in a press release. 'In addition to the large sample size and 30 years of follow-up, we assessed several different aspects of longevity and healthy aging as well as very comprehensive information on nutritional and lifestyle habits that were collected every four years after the initiation of the study.' The study followed 47,513 women using dietary and health data from the Nurses' Health Study dating back to 1984. While not yet peer-reviewed or published, the supporting data is extensive, experts say, and its conclusion lines up with several other studies that have found coffee to have beneficial effects. 'The data is quite consistent that coffee consumption is actually beneficial,' a Tufts University professor not affiliated with the study told The New York Times. The study looked at the frequency with which the participants drank coffee, tea, cola or decaffeinated coffee, while accounting for other factors that could influence health aging, such as body weight, smoking, alcohol use, physical activity, education level and protein consumption. Every four years, researchers collected follow-up information on the participants' nutritional and lifestyle habits, including regular caffeine consumption. After three decades, there were 3,706 women who met the definition of a health ager: 'living to age 70 or older, being free from 11 major chronic diseases, maintaining physical function, having good mental health, exhibiting no cognitive impairment and showing no memory complaints.' In mid-life, those same woman consumed, on average, 315 mg of caffeine per day, or about one and a half large cups of coffee. The vast majority of that caffeine intake came from regular coffee, according to the study. 'For women in the healthy agers group, each extra cup of coffee per day was tied to a 2% to 5% higher chance of doing well later in life, up to five small cups per day, or about 2.5 cups according to today's measures,' the news release stated. Alternatively, researchers found no link between healthy aging and decaffeinated coffee or tea. 'The health benefits apppeared specific to coffee, rather than caffeine more broadly,' Mahdavi told Fox News Digital. '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.' Caffeinated soda, the study found, lowered participants' chances of healthy aging by 20 percent to 26 percent. '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. While this study adds to prior evidence suggesting coffee intake may be linked with healthy aging, the benefits from coffee are relatively modest compared to the impact of overall healthy lifestyle habits and warrant further investigation.' Despite the generous sample size, Mahdavi noted that the study mostly examined the health and habits of white, educated female health professionals. 'Further work is needed to confirm generalizability to broader populations,' she told Fox News Digital, adding that, while the results are positive for coffee drinkers, the study doesn't show a direct causal relationship between the beverage and long-term health. In other words, there's no guarantee that starting a coffee habit will lead to a healthier aging process, but the study suggests that coffee drinkers don't necessarily need to cut back on the beverage in an attempt to maintain their health as they get older, David Kao, professor of medicine at the University of Colorado Anschutz Medical School told CNN. For those people who aren't already coffee drinkers, or abstain from caffeine, Mahdavi said her team does not recommend taking up the habit. People with medical concerns including high blood pressure, sleep issues or anxiety, should speak with a healthcare provider before drinking coffee, as it may not be advisable.

30-Year Study Reveals Coffee's Surprising Effect on Women Over 70
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Women who consume caffeinated coffee in midlife may boost their odds of aging well, according to a 30-year study. The findings suggest that a daily cup of coffee may do more than energize—it might support physical and mental health into an aging adult's golden years. The research, which was presented at the NUTRITION 2025 conference by Harvard T.H. Chan School of Public Health fellow Dr. Sara Mahdavi, analyzed data from the Nurses' Health Study, which began in 1984 and focused on nearly 50,000 women aged 45-60. Stock image: Two cups of coffee.

"Given its rich mix of bioactives, we wanted to examine how midlife intake may relate to healthy aging outcomes decades later—especially in a well-characterized cohort with repeated dietary measures." Researchers found that women who drank regular, caffeinated coffee—not tea or decaf—had a modest, but measurable increase in the likelihood of meeting criteria for "healthy aging" by age 70. These criteria included being free from 11 major chronic diseases, having intact physical function and mental health, and reporting no memory complaints. "Caffeine likely plays a role, but it's not the only factor," Mahdavi said. "Caffeinated coffee contains a broader range of bioactive compound—including certain polyphenols and diterpenes—that may be altered or diminished during decaffeination. "It's also possible that individuals who drink decaf differ systematically in health or behavior, though we adjusted for many of those variables." What To Know On average, women in the study who aged in a healthy way consumed around 315 mg of caffeine daily—roughly equivalent to three small cups of coffee. Each additional cup was tied to a 2-to-5% increase in the odds of healthy aging, up to a threshold of five small cups per day. The researchers noted that, for most people, two cups of coffee per day are generally safe and potentially beneficial. By contrast, soda consumption was associated with a 20-to-26% reduction in the likelihood of healthy aging, which suggests not all caffeine sources offer similar benefits. "The clearest takeaway was how consistent the findings were," Mahdavi told Newsweek. "Even after accounting for factors like smoking, [body mass index] and overall diet quality, moderate caffeinated coffee intake in midlife remained positively associated with healthy aging. "By contrast, cola consumption was associated with a substantially lower likelihood of aging well—nearly four times the magnitude, in the opposite direction." Health Benefits of Coffee Previous research has linked coffee consumption to a range of health benefits, including a reduced risk of several chronic conditions. Studies published in journals such as The New England Journal of Medicine and Circulation (NEJM) have found associations between regular coffee consumption and lower rates of Type 2 diabetes, Parkinson's disease, stroke and cardiovascular disease. A 2012 study in NEJM involving more than 400,000 participants found that people who drank coffee had a lower risk of death over the study period, whether it was caffeinated or decaf. A 2017 umbrella review in The BMJ found that coffee consumption was, "more often associated with benefit than harm," for a range of health outcomes. However, researchers have also cautioned that drinking too much coffee may pose risks for people with certain conditions, or low caffeine tolerance. "Not all beverages are equal when it comes to long-term health," Mahdavi said. "Moderate caffeinated coffee—1-to-3 cups per day—may support healthy aging, but more importantly, it can be part of a broader lifestyle that includes nutrient-rich foods, regular physical activity and avoiding harmful exposures. "The study adds to the growing body of evidence that everyday dietary choices, even in midlife, matter for how we age."

Coffee Could Be The Secret to Healthy Aging For Women, Scientists Discover
The daily ritual of imbibing a hot cup of freshly brewed and fragrant coffee isn't just good for the soul – it may be one of the ways to smooth the road to healthy aging for women. In a study of 47,513 women in the US with data spanning 30 years, scientists have found that long-term moderate coffee consumption in mid-life is positively correlated with the markers of healthy aging. "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," says Sara Mahdavi, nutrition scientist at Harvard University and the University of Toronto. "The findings suggest that caffeinated coffee – not tea or decaf – may uniquely support aging trajectories that preserve both mental and physical function." To assess the long-term impact of a daily cuppa (or two) on aging, Mahdavi and her colleagues made a careful study of data collected as part of the Nurses' Health Study, a series of epidemiological studies that examine the long-term impacts of various factors on the health of nurses in the US. They examined health and dietary intake data collected since 1984, all the way up to 2016. Healthy aging was defined as living to 70 years or older, maintaining good physical function, staying free from 11 major chronic diseases, and with no cognitive, mental health, or memory impairment. The researchers also adjusted for other factors that might influence health, such as smoking, alcohol consumption, level of physical activity, and body-mass index. By 2016, the researchers identified 3,706 women who qualified as healthy agers. For this group, around 80 percent of their average daily caffeine intake came in the form of three small cups' worth of coffee. By contrast, tea and decaffeinated coffee were not associated with any of the markers of healthy aging; and cola intake was associated with a negative impact for the markers of healthy aging. In other words, coffee had a positive effect; tea and decaf were neutral; and cola had a negative effect. For the healthy agers, each additional cup of coffee, up to five small cups a day, boosted the odds of healthy aging by between 2 and 5 percent. For the cola drinkers, each cup per day reduced the odds of healthy aging by 20 to 26 percent. Of course, coffee isn't a magic bullet for your health; you should still look after yourself in other ways, Mahdavi says. "These results, while preliminary, suggest that small, consistent habits can shape long-term health. Moderate coffee intake may offer some protective benefits when combined with other healthy behaviors such as regular exercise, a healthy diet, and avoiding smoking," she explains. "While this study adds to prior evidence suggesting coffee intake may be linked with healthy aging, the benefits from coffee are relatively modest compared to the impact of overall healthy lifestyle habits and warrant further investigation." The research has been presented at the NUTRITION 2025 conference in Orlando, Florida.

Brewed for longevity: Drinking coffee could help women live longer
A new study by the American Society of Nutrition has found that women who drink caffeinated coffee in their 40s and 50s may be more likely to stay mentally sharp, physically strong, and free from major illnesses as they research, which followed nearly 50,000 women for 30 years, shows that moderate coffee intake in midlife is linked to "healthy ageing", which is defined as living beyond 70 with good physical function, no memory issues, and freedom from chronic diseases like diabetes, heart disease, or ALL CAFFEINE SOURCES ARE EQUAL While coffee drinkers appeared to benefit, the study found no such advantage with decaffeinated coffee or fact, women who drank more cola, another source of caffeine, were less likely to age healthily.'Caffeinated coffee, not tea or decaf, may uniquely support ageing trajectories that preserve both mental and physical function,' said lead researcher Dr. Sara Mahdavi of Harvard T.H.

However, she added that coffee is only one piece of the puzzle. Exercise, a balanced diet, and avoiding smoking are still the biggest factors for healthy researchers also note that up to two cups of coffee a day is generally safe for most people, though more may be fine for differences can affect how well individuals tolerate caffeine.

Drinking coffee may boost odds of aging well, study finds
Anew study implies that a key to healthy aging may be found in your daily coffee consumption. Researchers in a report published on the National Library of Medicine's website infer that drinking moderate amounts of caffeinated coffee could help you live longer. Why you should care Researchers evaluated the consumption of coffee, tea, sodas, and decaf coffee consumption of over 47,000 women who were part of the Nurses' Health Study, per researchreleased at the annual meeting of the American Society for Nutrition in Orlando, CNN reported. Women examined in the study were middle-aged and were monitored for 30 years. The study noted that in the 30-year follow-up more than 3,000 women met the criteria for healthy aging, which is defined as living past 70 years old, not having 11 major chronic diseases and having no issues with physical function, mental health, cognition, or memory. RELATED: Drinking coffee or tea may lower the risk of certain cancers The study noted that women between the ages of 45 to 60 consumed an average of 315 milligrams of daily caffeine. Each additional cup of coffee that exceeded 80 milligrams each day is linked to 2% to 5% greater odds of healthy aging, which is 2.5 cups of coffee. Meanwhile, the study showed that consuming tea or decaffeinated coffee — and cola or other caffeinated sodas was connected to a lower chance of healthy aging. Lead study author Dr. Sara Mahdavi, a post-doctoral fellow at Harvard T.H. Chan School of Public Health, told the New York Post that the data in the study suggests that caffeinated coffee not tea or decaf might support aging in a way that preserves mental and physical ability. RELATED:What the latest study on coffee says about heart risk Mahdavi's initial findings for the study identified other factors that impact healthy aging, like weight, smoking, alcohol use, physical activity, education level and protein intake. She also told CNN that moderate coffee consumption, which she defines as three cups daily, may be part of a healthy diet for adults, but adds that this isn't a recommendation for everyone to start drinking more coffee to enhance healthy aging. Madhavi explained to the New York Post that while this study is a continuation of previous evidence implying coffee intake may be linked with healthy aging, the benefits from coffee are modest compared to the effect of overall healthy lifestyle habits like diet and exercise and require more research.
