Why the 40s are the best time to start the longevity lifestyle, according to experts
A recent study reveals that dietary choices in midlife significantly impact healthy aging. Adhering to diets rich in plant-based foods, with moderate intake of healthy animal products, increases the likelihood of reaching age 70 without chronic diseases and maintaining cognitive, physical, and mental well-being. Conversely, high consumption of ultra-processed foods diminishes these chances. Let's just confess it. All of us are wondering how movie stars like Tom Cruise, Angelina Jolie, Salma Hayek, and Jennifer Aniston are looking almost half their age! No, it's not just about the cosmetic procedures they might have done. It's deeper than that. What you eat plays a crucial role in your health. And if you want to age like fine wine, the key is on your plate! A new study has found that what you eat in your 40s and 50s could shape how well you live into your 70s and beyond. Researchers from Harvard T.H. Chan School of Public Health, the University of Copenhagen, and the University of Montreal have found that sticking to certain diets can significantly increase the odds of aging without chronic diseases, while maintaining physical, cognitive, and mental health. The findings are published in Nature Medicine . Let's unlock the secret to longevity and healthy aging. Diet and healthy aging Longevity is not just about how many years you live, its about the quality of life. The researchers have found that a healthy diet rich in plant-based foods, with low to moderate intake of healthy animal-based foods and lower intake of ultra-processed foods, was linked to a higher likelihood of healthy aging. defined as reaching age 70 free of major chronic diseases and with cognitive, physical, and mental health maintained. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Fastest Selling Plots of Mysore from 40L | 40+ Amenities PurpleBrick Learn More Undo This study is among the first to examine multiple dietary patterns in midlife in relation to overall healthy aging. 'Studies have previously investigated dietary patterns in the context of specific diseases or how long people live. Ours takes a multifaceted view, asking, how does diet impact people's ability to live independently and enjoy a good quality of life as they age?' co-corresponding author Frank Hu, Fredrick J. Stare Professor of Nutrition and Epidemiology and chair of the Department of Nutrition at Harvard Chan School, said in a statement. The study To understand the link between healthy eating and longevity, the researchers looked at data from the Nurses' Health Study and the Health Professionals Follow-Up Study. They examined the midlife diets and eventual health outcomes of more than 105,000 women and men aged between 39 and 69 over the course of 30 years. The participants were asked to complete dietary questionnaires regularly. The researchers looked at how well participants adhered to eight healthy dietary patterns. Alternative Healthy Eating Index (AHEI) Alternative Mediterranean Index (aMED) Dietary Approaches to Stop Hypertension (DASH) Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) Healthful plant-based diet (hPDI) Planetary Health Diet Index (PHDI) Empirically Inflammatory Dietary Pattern (EDIP) Empirical dietary index for hyperinsulinemia (EDIH). These diets were high on fruits, vegetables, whole grains, unsaturated fats, nuts, and legumes. Some of them also included low to moderate intake of healthy animal-based foods such as fish and certain dairy products. The researchers also looked at how the participants consumed ultra-processed foods, which are industrially manufactured, often containing artificial ingredients, added sugars, sodium, and unhealthy fats . The findings The researchers found that 9,771 participants (9.3%) aged in a healthy manner. Sticking to any of these healthy diets was linked to overall healthy aging, including cognitive, physical, and mental health. The AHEI diet scored the most, due to its ability to prevent chronic diseases. The participants who scored highest in AHEI adherence were 86% more likely to age healthfully by 70, and had a 2.2 times greater chance of healthy aging at 75, compared to those with the lowest adherence. The AHEI diet was rich in fruits, vegetables, whole grains, nuts, legumes, and healthy fats. It was low in red and processed meats, sugar-sweetened beverages, sodium, and refined grains. No Ozempic Here: Lizzo Reveals Real Story Behind Her Transformation PHDI followed the AHEI diet. This diet prioritizes human and environmental health by focusing on plant-based foods and minimizing animal-derived products. The study also showed that higher intake of ultra-processed foods, especially processed meat and sugary and diet beverages, was associated with lower chances of healthy aging. 'Since staying active and independent is a priority for both individuals and public health, research on healthy aging is essential. Our findings suggest that dietary patterns rich in plant-based foods, with moderate inclusion of healthy animal-based foods, may promote overall healthy aging and help shape future dietary guidelines,' co-corresponding author Marta Guasch-Ferré, associate professor in the Department of Public Health at the University of Copenhagen and adjunct associate professor of nutrition at Harvard Chan School, said. 'Our findings also show that there is no one-size-fits-all diet. Healthy diets can be adapted to fit individual needs and preferences,' lead author Anne-Julie Tessier, assistant professor in the Department of Nutrition at the University of Montreal, researcher at the Montreal Heart Institute, and visiting scientist at Harvard Chan School, added.

Harvard has collected 3 million biological samples over decades. Now researchers may not have the money to preserve them.
The samples are kept at temperatures as low as minus-170 degrees Celsius (or minus-274 degrees Fahrenheit), in a network of liquid nitrogen freezers at the Chan School as well as at Brigham and Women's Hospital, according to 'If we really don't have any funding, we would lose the samples,' said Dr. Walter Willett, a Harvard professor and a principal investigator for the studies, in an interview. 'We're doing everything possible to not let that happen.' Advertisement The two programs affected are among the most comprehensive and long-running public health studies in the country. The Nurses' Health Study is A similar project, the Health Professionals Follow-Up Study, tracks lifestyle and nutrition factors for men. Advertisement The two projects have yielded a number of landmark findings, including the link between alcohol consumption and breast cancer and the effects of trans fats on heart disease. The dataset generated from the massive project has informed countless additional studies by other researchers. Related : As part of the projects, researchers collected biological samples from roughly 350,000 individuals, monitoring various components, including nutrients, contaminants, and hormone levels. That research has been crucial to the growing understanding of factors that contribute to breast cancer, heart disease, and dementia, Willett said. 'Looking at what's going on inside the body a few decades before the disease occurs, that's what we can do [with the samples],' he said. 'That's really critical, because we know for many cancers, it's not what's in the blood or in the urine at the time of diagnosis, it's what was going on decades before that's probably most important. And we can go back to the samples and look at that today.' The collection of samples is among the most comprehensive in the world, Willett said. Its scientific potential — which will only increase as new research technologies are developed — is something that 'no amount of money can buy,' he added. Related : Both projects were funded in large part by two grants issued by the National Institute of Health's National Cancer Institute. Those grants were terminated on May 6, according to an affidavit filed by Willett June 2. Now, researchers are scrambling to keep the freezers running. Advertisement 'We have probably a couple of months worth of resources for paying our nitrogen bills,' Willett said. 'But the nitrogen company is very efficient in cutting off supply if we don't pay.' Though it's not clear exactly when the funding will run out, Willett said the research team may soon have to decide which samples are kept and which will be allowed to spoil. But because the sweeping nature of the study relies on having multiple samples from hundreds of thousands of people over a multi-year period, it's difficult to say which will be more useful for research purposes. 'We don't yet know who's going to get breast cancer,' Willett said. 'Which makes it impossible to predict exactly which samples will be the most valuable.'

Science Just Linked These Popular Fruits To Boosted Longevity In Women
A new study found that consuming foods rich in flavanoids can help women age better. Over 24 years, researchers found that women who consumed a diet rich in flavanoids had a lower risk of frailty, impaired physical function, and poor mental health. Here's what else you should know about this essential chemical compound. There's no magic pill that will skyrocket you to peak longevity, but recent research has uncovered a slew of factors that can help women age in the healthiest way possible. And they're surprisingly simple (and don't involve crazy injections!). Yep, there's one more healthy aging hack to add to the list, and it's a delicious one: Eat more berries. New research suggests that loading up on foods that contain flavonoids (like berries) is linked with a slew of factors associated with healthy aging. Of course, throwing some strawberries on top of your morning granola once in a while won't *guarantee* you'll be a healthy ager, but it can help. And it's an easy enough thing to incorporate into your lifestyle. Plus, you might already be regularly tossing back flavonoid-rich foods in which case, keep going! With that in mind, here's what scientists uncovered about flavonoids and healthy aging, plus how to put the findings to work for you. Meet the experts: Keri Gans, RDN, dietitian and host of The Keri Report podcast; Scott Keatley, RD, co-founder of Keatley Medical Nutrition Therapy The study, which was published in The American Journal of Clinical Nutrition, analyzed data on diet, lifestyle habits, and health from 62,743 women and 23,687 men collected over 24 years from two long-term studies (the Nurses' Health Study and Health Professionals Follow-Up Study). The researchers discovered that women who consumed the highest intakes of flavonoids—equivalent to three servings of berries a day or more—had a 15 percent lower risk of frailty, 12 percent lower risk of impaired physical function, and 12 percent lower risk of poor mental health at the end of the study period compared to those who consumed the least amount of flavonoids. (The link wasn't as strong for men, although they still seemed to get a mental health boost.) Overall, the researchers concluded that 'incorporating flavonoid-rich foods in the diet may be a simple strategy to support healthy aging.' Basically, they're a natural chemical compound. 'Flavonoids are a class of natural compounds found in fruits, vegetables, tea, and cocoa,' says Scott Keatley, RD, co-founder of Keatley Medical Nutrition Therapy. These compounds have antioxidant properties, points out Keri Gans, RDN, dietitian and host of The Keri Report podcast. 'They help protect our cells from free radicals that may cause damage to our body and contribute to inflammation,' she explains. The researchers didn't uncover exactly why flavonoid-rich foods are linked to healthy aging, but here are a few theories from experts. 'Research suggests flavonoids may support brain health, heart health, and overall cellular function—all important pieces of staying healthy as we get older,' Gans says. Also, flavonoids are known to tamp down on inflammation in the body, and inflammation is linked to a higher risk of developing a slew of serious health conditions that can interfere with your ability to age in a healthy way, Gans points out. Flavonoids are also found in plant foods, and eating a diet rich in plants has already been linked with longevity. But there may be another elements of flavonoid-rich foods that could explain this link that we just don't yet understand or recognize. As the researchers put it: 'It is possible that our findings might be due to other constituents found in the foods that contribute most to flavonoid intake." While berries are rich in flavonoids, Gans notes that you can also get this compound from a range of plant-based foods, including: Apples Citrus fruits Onions Red cabbage Grapes Soybeans Dark chocolate Red wine Tea If you want the best flavonoid bang for your buck, Gans recommends reaching for berries (which makes sense why the study points these out). 'Berries, especially blueberries and blackberries, are among the richest sources,' she says. Still, Gans stresses that it's good to mix things up in your diet, so you don't have to pick one type of flavanoid-rich food and stick with it. 'The goal is to include a variety of flavonoid-rich foods throughout the week to get the most benefit,' she says.

Trump cuts threaten ‘irreplaceable' Harvard stockpile of human feces, urine
Kept frozen by liquid nitrogen inside laboratories at Harvard University are more than 1.5 million biospecimens that have mere 'weeks' left until they spoil. As Harvard fights the Trump administration in court over the suspension of nearly $3 billion in federal funding, soon there won't be enough money left to keep the freezers running. The nearly 50 years of collected human feces, urine, blood, tumors and even toenail clippings could have consequential implications for the future health of Americans, and yet, they're at risk of being lost if funding slashed by the Trump administration isn't restored. The mother lode collection housed at Harvard has supported generations-long chronic disease risk studies that have fundamentally shaped major scientific and medical advancements. Read more: Funding cuts, lawsuits, foreign students: The latest on Trump's war with Harvard University The studies have lead to major breakthroughs, including links between cigarettes and cardiovascular disease and alcohol consumption and breast cancer. The research also uncovered the dangers of trans fats, which the U.S. has now largely restricted. The biological samples collected during the studies are 'irreplaceable,' according to Walter Willett, a professor of epidemiology and nutrition at the Harvard T.H. Chan School of Public Health and one of the most sought-after nutritionists internationally. And some of the study participants could even die before the next check-in period, he said. 'No other institution in the world has this data,' Willett wrote in a May 30 court affidavit detailing the impacts of federal funding cuts on his research. Read more: Over 12,000 Harvard alums lend weight to court battle with Trump in new filing The money can't be replaced with private funding, Willett said, and Harvard has told him it won't be able to supplement lost dollars. Willett filed his affidavit last month as part of a lawsuit in which Harvard faculty members are suing the Trump administration. President Donald Trump has gone after the world's wealthiest higher education institution and its funding in the name of antisemitism, claiming Harvard has failed to protect Jewish students, particularly in the wake of the war in Gaza. Willett's research is funded by two federal grants from the National Cancer Institute at the National Institutes of Health. On May 6, he was informed the funding had been terminated for both the Nurses' Health Study and Health Professionals Follow-Up Study. The Nurses' Health Study, which began with its first installment in 1976, followed by Willett's involvement in 1989, started tracking a cohort of 116,000 women in order to understand how 'diets and lifestyle relate to the risk of developing cancer,' Willett's affidavit said. In addition to collected biological samples, much of the data comes from questionnaires filled out by study participants every two years. The Nurses' Health Study has associated circulating sex hormones and postmenopausal breast cancer risk; connected higher vitamin D levels linked with lower risks of both colon polyps and colon cancer; and played a role in discovering genetic variations involved in cancers and cancer-related factors. The Health Professionals Follow-up Study is parallel research that has been tracking the diets of 52,000 adult men who have been diagnosed with cancer from all states in America. 'This study collects data about heart attacks, cancer and other conditions that share risk factors with heart disease, such as dementia and Parkinson's disease,' Willett wrote. 'Dozens of other grants studying many diseases have used the dataset collected by this study.' Read more: 'We are not just fighting for Harvard': For alums, this year feels different The male-focused study, which has also been used for women's research, has unearthed the harmful effects of trans fat; made connections between healthy plant foods and lower cardiovascular risk; linked dietary patterns and prostate cancer risk; and associated olive oil benefits with a lower risk of dying from dementia. There is another element of urgency in addition to the uncertain future of the biological samples: Willett says some participants may die before researchers are able to follow up with them next year for new information on their physical and cognitive functions. 'The termination of my grants thus jeopardizes our chance to collect data from the living study participants who have voluntarily contributed personal information over the last four decades,' Willett wrote. 'This would deprive all Americans from the benefits of knowledge about diet, other aspects of lifestyle, and use of medications that enhance their possibilities of living longer and healthier lives.' Since April, the Trump administration has launched a series of attacks against Harvard. Nearly $3 billion in federal funding has either been cut or frozen, and there was also a wave of federal research grant terminations. The Harvard T. H. Chan School of Public Health announced in April that it was facing a 'significant budget crisis' resulting in layoffs and the non-renewal of two building leases. Since then, every one of the school's direct federal grants have been terminated and the school has even taken to social media to ask for donations. Federal funding makes up 46% of Harvard Chan School's budget.

Following a further $450 million in announced cuts, the university amended its lawsuit. 'No government — regardless of which party is in power — should dictate what private universities can teach, whom they can admit and hire, and which areas of study and inquiry they can pursue,' the suit reads.

Experts reveal that THIS diet can reduce heart disease risk
A recent Harvard study, presented at NUTRITION 2025, reveals that food quality is paramount for heart health, surpassing the focus on simply cutting carbs or fats. The decades-long research, involving nearly 200,000 participants, demonstrates that diets rich in whole grains, fruits, and vegetables significantly lower coronary heart disease risk by approximately 15%, regardless of whether they are low-carb or low-fat. Heart diseases are on the rise, with it still being one of the leading causes of death globally. Cardiovascular diseases account for 17.9 million deaths worldwide in 2023. Diet plays a crucial role in heart health and in reducing the risk of heart disease. A recent study examined the relationship between heart disease and diet and has identified one that benefits the heart. A large study by researchers at Harvard T.H. Chan School of Public Health found that the quality of the food matters more than cutting carbs or fat. The findings will be presented at NUTRITION 2025 , the flagship annual meeting of the American Society for Nutrition, which will be held in Orlando this week. Quality over quantity The new study found that when it comes to protecting the heart , the types of foods one eats may be more important than whether they follow a low-carbohydrate or low-fat diet. To understand what works in favour of the heart, the researchers followed almost 200,000 people for several decades, and observed that the quality of food consumed matters as much as following a low-carbohydrate or low-fat diet. The findings suggested that choosing healthy, high-quality foods is key to protecting the heart. Previously, low-carbohydrate and low-fat diets have been endorsed by health experts for their potential health benefits, such as weight management and improved blood sugar and cholesterol levels. However, the impact of these diets on reducing heart disease risk has remained an ongoing debate. 'We found that what you eat on low-carb or low-fat diets matters just as much as the diet itself. Healthy versions of these diets—those rich in plant-based foods and whole grains—were linked to better heart health outcomes and improved metabolic function. In contrast, low-carb and low-fat diets emphasizing unhealthy foods were associated with a higher risk of heart disease,' said Zhiyuan Wu, PhD, a postdoctoral fellow in the lab of Qi Sun, MD, ScD, at Harvard T.H. Chan School of Public Health, said in a release. The study To understand the link, the researchers analyzed data from three large cohorts: 43,430 men in the Health Professionals Follow-Up Study (1986–2016), 64,164 women in the Nurses' Health Study (1986–2018), and 92,189 women in the Nurses' Health Study II (1991–2019). The scientists followed these nearly 200,000 participants for several decades, tracking their dietary habits and whether they developed heart disease. Participants completed detailed food frequency questionnaires over time, allowing researchers to score their diets based on the quality of carbohydrates, fats, and proteins consumed. The researchers classified carbohydrates, fat,s and proteins from foods such as whole grains, fruits, vegetables, nut,s and legumes as high-quality nutrients, or healthy, while carbohydrates from potatoes and refined grains, as well as saturated fats and proteins from animal-based foods, were categorized as low-quality, or unhealthy. For more than 10,000 participants, the team also examined blood metabolites to understand how diet quality influenced metabolic health. 'This approach allowed us to better understand the biological effects of these diets and strengthened our findings,' Wu said. Take away The researchers found that the participants who followed a healthy low-carbohydrate or low-fat diet had a lower risk of developing coronary heart disease, while those on unhealthy versions saw an increased risk. These healthy diet patterns, whether a low-carbohydrate or low-fat diet, lowered the risk of developing heart disease by about 15%. You Clean Your Diet, But What About Your Company? Sadhvi Bhagawati Saraswati's Powerful Truth 'Our findings suggest that improving food quality is crucial for improving heart health. Regardless of whether someone follows a low-carbohydrate or low-fat diet, emphasizing whole, minimally processed and plant-based foods and limiting refined grain, sugar, and animal foods, can significantly reduce the risk of coronary heart disease,' Wu added. What to do To keep heart diseases at bay, the researchers suggest incorporating more whole grains, fruits, vegetables, nuts and legumes while cutting back on processed meats, refined carbs and sugary foods. Pro tip? Check food labels and be mindful of added low-quality ingredients, such as added sugars in juices and processed snacks.
