15 Minutes of This Exercise May Lower Mortality Risk by 19%, New Study Says
Upgrade your daily walk with this small tweak that could offer lots of health benefits. Reviewed by Dietitian Mandy Enright, M.S., RDN, RYTKey Points A new study found that 15 minutes of fast walking each day may lower mortality risk by 19%. Fast walking lowered overall mortality risk and had an especially large impact on heart health-related deaths. While slower walking can be a great form of exercise, smaller quantities of fast walking may offer extra is one of the simplest and most effective ways to boost overall health, as it can offer benefits like reduced mortality, improved blood sugar levels and better heart health. Studies suggest that even light walking can have a positive impact on outcomes like reducing blood pressure. But most research on walking focuses on middle-to-high-income white populations, leaving gaps in understanding how walking impacts low-income and racial minority groups. These populations often face unique challenges, such as limited access to safe walking spaces, higher exposure to pollution and barriers to healthcare, all of which can contribute to higher mortality rates. To address the lack of research on walking in underserved communities, scientists used data from the Southern Community Cohort Study (SCCS) to explore how daily walking impacts overall and specific causes of mortality, and the results were published in the American Journal of Prevention Medicine. How Was The Study Conducted? This study enrolled about 85,000 participants aged 40 to 79 from the Southern Community Cohort Study (SCCS), focusing on individuals who had not undergone cancer treatment in the year prior to joining. The SCCS is a large study focused on understanding why racial disparities exist in cancer and other chronic diseases, particularly in low-income populations. What makes this study unique is that over half of the participants reported earning less than $15,000 a year, and about two-thirds of them are Black. This diverse group offers a rare chance to examine how daily walking affects health outcomes in low-income, racially diverse populations. At the start of the study, participants completed detailed questionnaires covering their daily walking habits, lifestyle choices and medical history. Participants reported how much time they spent walking each day, distinguishing between slow walking (e.g., walking the dog or light exercise) and fast walking (e.g., brisk walking or climbing stairs). They could report anywhere from 0 to 720 minutes per day, and their responses were grouped into four categories: no walking, less than 30 minutes, 30-60 minutes and more than 60 minutes. These categories align with health guidelines recommending at least 30 minutes of daily activity. The study also explored fast walking in smaller increments (e.g., 15-minute intervals). In addition to walking, the study measured five key lifestyle factors linked to mortality: smoking, alcohol use, physical activity, sedentary behavior and diet quality. These factors were combined into a composite lifestyle score, with higher scores indicating healthier lifestyles. The study tracked participants' vital status and causes of death through the National Death Index until December 31, 2022. Deaths were categorized into major causes, including cardiovascular disease (CVD), cancer, other diseases and external causes like accidents. Specific types of CVD, such as heart disease and stroke, were also analyzed due to their prevalence. This comprehensive approach allowed researchers to examine how daily walking and lifestyle factors influence overall and cause-specific mortality in a diverse, low-income population. What Did This Study Find? The study found that, among the studied population, fast walking was significantly linked to lower overall mortality, while slow walking showed only a slight, non-significant benefit. For those who walked slowly for more than three hours a day, there was a 4% lower risk of death, but this result wasn't strong enough to be considered statistically significant. On the other hand, fast walking showed clear benefits; even just 15 minutes a day was associated with a 19% lower risk of death. When researchers accounted for other lifestyle factors like diet, smoking and physical activity, the benefits of fast walking remained strong, while the slight benefits of slow walking became even less noticeable. Overall, fast walking stood out as a simple and effective way to reduce the risk of death. Additional analyses confirmed the findings, showing consistent results for the link between time spent walking (both slow and fast) and overall mortality, even when including participants who died within the first two years. Fast walking showed similar patterns of reduced risk across all specific causes of death, but the strongest benefits were seen for cardiovascular disease (CVD). People who walked fast for more than 60 minutes a day had a 20% lower risk of dying from CVD compared to those who didn't walk at all. Within CVD, the biggest reductions in risk were seen for heart diseases, particularly ischemic heart disease and heart failure. Interestingly, the benefits of fast walking were independent of other physical activities, meaning fast walking provided its own unique health boost. Even for individuals who were already active, those who walked fast for more than 60 minutes a day saw additional benefits, with a 16% lower risk of death compared to those who didn't walk fast at all. There are a few limitations to keep in mind when interpreting these results. First, since participants reported their own daily walking habits, some may have included other activities like climbing stairs, which could lead to some misclassification. Second, physical activity data was only collected at the start of the study, so it wasn't possible to see how changes in activity over time might affect the results. Additionally, because this was an observational study, it's hard to completely rule out other factors, like pre-existing health conditions or unmeasured influences, that could have impacted the findings. How Does This Apply To Real Life? This study highlights that walking, especially fast walking, can be a powerful tool for improving health and reducing the risk of death, even with just 15 minutes a day. For people who may not have access to gyms or structured exercise programs, walking offers an easy, low-cost way to stay active. The findings are particularly important for underserved communities, where barriers like limited access to safe walking spaces or healthcare can make it harder to prioritize health. The study also emphasizes that fast walking has unique benefits, even for those who are already active or engage in other forms of exercise. This means that adding a brisk walk to your daily routine can complement other activities and provide an extra health boost. Whether it's a quick walk around the block, climbing stairs at work, or picking up the pace while walking the dog, these small changes can add up. The key takeaway? You don't need fancy equipment or hours of free time; just lace up your shoes, pick up the pace and let your feet do the work for your health. Our Expert Take This study published in the American Journal of Prevention Medicine highlights that even small amounts of fast walking (just 15 minutes a day) can make a meaningful difference in overall health and longevity. For those where access to gyms or safe exercise spaces may be limited, this study offers an encouraging and accessible way to improve health outcomes. The findings also underscore the importance of making walking a part of daily life. Whether it's a brisk walk to the store, a quick loop around the neighborhood or simply picking up the pace during your usual routine, fast walking is a simple, low-cost activity with big health payoffs. Grab your sneakers, step outside and start reaping the benefits—your heart (and the rest of your body) will thank you. Read the original article on EATINGWELL

6 Best Teas for Brain Health, According to Dietitians
Key Takeaways Some teas have antioxidants, amino acids, and plant compounds that can support long-term cognitive health. Green tea is one of the most researched options, thanks to its L-theanine, catechins, and EGCG. Caffeine-free options can still boost focus and mental energy, making them valuable down that cup of coffee if you're after calm, sustained focus. Drinking tea can support your brain without the caffeine crash. Compounds like L‑theanine and polyphenols in green tea help smooth out energy spikes and protect neurons from oxidative stress. Herbal blends pull their weight, too, with research suggesting they can help with alertness and mental stamina. In other words, the right cup of tea can do more than warm your hands. We asked health experts to break down the best teas for brain health—both classic and herbal—that deliver measurable perks for your mood and memory. Related: 7 Foods to Help Keep Your Brain Healthy and Sharp, According to Nutrition Experts Green Tea The brain can be especially susceptible to oxidative stress, and the unique properties of green tea can help offset that. 'When most people think of teas to support brain health, green tea is usually what comes to mind due to its high potency of antioxidative properties,' says Chacha Miller, MS, RD, LDN, pediatric dietitian and founder of The Carda Mom. 'It's rich in catechins, which are a type of polyphenol that acts as a powerful antioxidant that helps protect cells from damage caused by oxidative stress and free radicals.' Green tea also contains L-theanine, an amino acid shown to reduce stress and improve focus. Research consistently backs the link between green tea and cognitive function: One double-blind study in Molecules found that adults who consumed decaffeinated green tea catechins daily for 12 weeks showed improvements in working memory and attention. Aim for about two to three cups a day (roughly 16–24 ounces) to match the L-theanine and polyphenol ranges used in cognition studies without overdoing the caffeine. Turmeric Tea 'Another favorite of mine for brain health is turmeric tea, also due to its high antioxidant content,' says Miller. 'It's rich in curcumin, which is known for its anti-inflammatory and antioxidant effects.' Turmeric tea has earned attention in Ayurvedic medicine for its brain-supportive properties. Emerging research suggests that curcumin may support positive mood, memory, and overall cognitive function, particularly in aging adults. 'I often suggest adding a small dash of black pepper to turmeric tea to help with the absorption of curcumin and get the most benefit,' Miller adds.

"Chamomile tea can be a simple, natural way to support brain health, mostly by helping you sleep better and feel calmer,' says Raj Dasgupta, MD, FACP, FCCP, FAASM, board-certified physician and chief medical advisor for Sleepopolis. 'One of its main active compounds, apigenin, interacts with receptors in the brain that help you relax, which may explain why so many people find it easier to wind down after drinking it.' Dasgupta says chamomile also has anti-inflammatory and antioxidant properties that may help protect the brain over time. 'While we still need more research on its direct effects on memory or cognition, what we do know is that reducing stress and sleeping well are two of the best things you can do for long-term brain health, and chamomile may gently support both,' he Chamomile tea is generally safe for most people, though Dasgupta suggests that anyone with ragweed allergies or those on certain medications should check with their doctor Mane Mushroom Tea Lion's Mane mushrooms are the focus of growing research suggesting they may support long-term brain function. 'Not a traditional tea, but this medicinal mushroom is gaining a lot of attention for cognitive health,' says Ehsan Ali, MD, an internal medicine physician and founder of Beverly Hills Concierge Doctor. 'Lion's Mane contains compounds called hericenones and erinacines, which have been shown to stimulate the growth of nerve growth factor (NGF), a protein that supports the growth and survival of neurons.' One study published in the International Journal of Molecular Sciences found that Lion's Mane may help protect against neurodegenerative diseases by promoting brain plasticity and regeneration. 'It's particularly useful for memory and focus over time, not just a short-term boost,' Ali adds. Many people brew it as a powdered tea or steep pre-packaged mushroom blends for a mellow, earthy sip. Peppermint Tea Turns out, peppermint tea isn't just for settling your stomach. 'Peppermint tea doesn't contain caffeine, but its menthol content can still offer a brain boost,' says Ali. 'Research suggests that peppermint aroma and ingestion may enhance memory, alertness, and cognitive performance.' One randomized trial in Human Psychopharmacology showed that drinking peppermint significantly improved cognitive performance and increased cerebral blood flow in healthy adults. 'It's a great option if you want a caffeine-free alternative that still helps with focus,' says Ali. Rosemary Tea If you're looking for a brain boost straight from the garden, rosemary tea might be worth steeping. 'A brew of rosemary tea is a great source of carnosic acid, which has neuroprotective effects that help improve memory and decrease mental fatigue,' says Jeremy Gurewitz, co-founder of Solace Health. A review in Molecules supports this link and identifies carnosic acid found in rosemary and sage as a neuroprotective compound with antioxidant and anti-inflammatory effects. The study suggests it may help prevent neuron damage linked to neurodegenerative disorders. Brew rosemary fresh for five to seven minutes for best results.
