Researchers Say Taking This Supplement Every Day Can Slow Down Aging
"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links."
Researchers just discovered yet another reason you might want to take an omega-3 supplement. When they analyzed data from 777 participants age 70 and older in the DO-HEALTH trial, they found that taking 1 gram of omega-3 fatty acids every day was linked to slower biological aging. Yes, many different factors affect how fast you age, but taking a supplement could be one easy way to help keep your cells younger for longer.
Omega-3 fatty acids are involved in the structure of our cell membranes, provide energy for our body and help form signaling molecules for our cardiovascular, pulmonary, immune and endocrine systems, according to the National Institutes of Health. On top of many other health benefits, this new research suggests omega-3 fatty acids may also be a key ingredient in the aging process.
'One of the most critical questions in the field of rejuvenation is whether a treatment exists that can effectively rejuvenate humans not just mice,' says Heike Bischoff-Ferrari, Dr.P.H., M.P.H., a clinical scientist and medical doctor with a focus on healthy longevity at the University of Basel, Switzerland, and co-author of the new study. 'This motivated us to explore whether three simple interventions — omega-3, vitamin D and exercise — influence the most reliable molecular markers of biological age: epigenetic clocks.'
Here's everything you need to know.
Epigenetic clocks are tools that look for chemical changes that occur in genetic material to identify patterns and, as a result, measure biological age. 'We age in a spectrum,' says Bischoff-Ferrari. 'Some people are biologically younger than their chronological age (age in our passport) and others are biologically older.'
A variety of epigenetic clocks have been invented to measure biological age in different ways, so there isn't a single test that can tell you definitively what your biological age is. The researchers who conducted this study used four epigenetic clocks to get a range of measurements.
'The good news is that we know today that only a small part (10 to 30%) of the variability of health span is explained by our genes,' says Bischoff-Ferrari. 'The rest is determined by our environment, socioeconomic factors and especially lifestyle, such as exercise and diet.' Bischoff-Ferrari and her colleagues used epigenetic clocks to measure the biological ages of people who took 1 gram of an algae-based omega-3 supplement daily, 2,000 IU of vitamin D daily and/or participated in a strength-training exercise program for 30 minutes three times per week.
People who took the omega-3 supplement every day for three years had a biological age that was an average of 3 months younger than their chronological age, according to three of the four epigenetic clocks. The fourth clock showed 'there was an additional benefit if omega-3 was combined with vitamin D and exercise,' says Bischoff-Ferrari. Three months may not sound like much, but Bischoff-Ferrari says it's enough to have an impact at the population level.
No one knows exactly why omega-3 fatty acids could have such a strong effect on the aging process, but there are plenty of hypotheses. 'Notably, these results complement previous clinical findings in the same trial (DO-HEALTH), which found that omega-3 lowered the rate of falls by 10% and reduced the rate of infections by up to 13%, while omega-3, vitamin D and exercise combined lowered the risk of pre-frailty by 39% and invasive cancer by 61%,' says Bischoff-Ferrari.
It seems as though omega-3 fatty acids, vitamin D and exercise could provide a triple-whammy of aging protection. 'It is well-documented in basic science that vitamin D prevents uncontrolled cell growth and has anti-inflammatory benefits,' says Bischoff-Ferrari. Meanwhile, exercise is famous for being 'a major driver of healthy longevity with protective effects on most age-related chronic diseases, such as heart disease, cancer, osteoporosis and diabetes,' she says.
This study shows how powerful small lifestyle changes (such as taking a supplement or starting a new exercise regimen) can be when it comes to protecting our health and slowing down the aging process of our cells.
As important as they are for our health and longevity, omega-3 fatty acids aren't easily created in our bodies, so we need to source them from food and supplements. Foods rich in omega-3s include fatty fish (such as salmon), nuts (like walnuts), seeds (chia seeds, for instance), plant oils (like soybean oil and fortified foods (such as some eggs, yogurt and drinks).
There are three main types of omega-3 fatty acids — ALA, DHA and EPA. There are no set recommendations for the amount of DHA and EPA you should consume, but males age 14 and older should aim for 1.6 grams of ALA every day, while the goal is 1.1 daily grams of ALA for females age 14 and older. People breastfeeding should get 1.3 grams of ALA every day and those who are pregnant should aim for 1.4 grams of ALA. If you're not getting enough from your diet, you may want to ask your doctor about taking an omega-3 supplement.$23.98 at amazon.com$33.44 at amazon.com$16.88 at walmart.com

Naps associated with increased risk of death, report says
June 5 (UPI) -- An afternoon snooze might seem appealing to middle-aged folks and seniors, but these naps could carry a high cost. People with certain types of napping patterns have a greater risk of an early death, researchers are slated to report at an upcoming meeting of the American Academy of Sleep Medicine. "People who slept longer during the day, had irregular daytime sleep patterns, or slept more around midday and early afternoon were at greater risk, even after accounting for health and lifestyle factors," lead researcher Chenlu Gao, a postdoctoral research fellow at Massachusetts General Hospital in Boston, said in a news release. The findings call into question the whole concept of the "power nap." For the study, researchers analyzed data on more than 86,500 people participating in the UK Biobank long-term health research project. These folks had their sleep habits monitored for a week using wrist devices, and researchers compared those habits to death records. Their average age was 63 at the time their napping was tracked. Nearly 5,200 people died during a follow-up of 11 years, researchers said. Results showed an increased risk of premature death for: • People who tended to take longer daytime naps • Folks whose napping patterns fluctuated frequently • People who napped between 11 a.m. and 3 p.m. This last observation contradicts academy guidelines, which encourages adults to limit themselves to "power naps" of no more than 20 to 30 minutes in the early afternoon, researchers noted. Naps that last longer than a half-hour can cause grogginess that undercuts the potential helpfulness of a siesta, researchers said. "Interestingly, the data that shows risks associated with napping around midday and early afternoon contradicts what we currently know about napping, so further research on that link could be warranted," Gao said. Gao is to present these findings Wednesday during the AASM's annual meeting in Seattle. Findings presented at medical meetings should be considered preliminary until published in a peer-reviewed journal. More information The Mayo Clinic has more on napping for healthy adults.

Federal cuts force families to make difficult, and potentially deadly, choices
A mother rushes into the emergency department cradling her 6-month-old baby. He is lethargic, seizing and in critical condition. The cause? Severely low sodium levels in his blood — a result of formula diluted with extra water to make it last longer. With grocery prices climbing and her SNAP benefits running out before the end of the month, she felt she had no other choice. This story is not an outlier. Pediatric clinicians across Wisconsin are seeing the real and devastating consequences of policies that fail to prioritize the health and well-being of children and families. And now, the situation could get worse. The Trump Administration's proposed 'skinny' budget for Fiscal Year 2026 includes deep and dangerous cuts to federal programs that form the backbone of public health in our communities. These proposed reductions include: $18 billion from the National Institutes of Health – stalling critical pediatric research and innovation $3.5 billion from the Centers for Disease Control and Prevention – compromising disease surveillance, immunization programs, and emergency response efforts $1.73 billion from the Health Resources and Services Administration – cutting access to essential primary and preventive care services for children and families $674 million from the Centers for Medicare & Medicaid Services – threatening the Medicaid and CHIP programs that provide health coverage to nearly half of Wisconsin's children. Opinion: We asked readers about wake boats on Wisconsin lakes. Here's what you said. And as if that weren't enough, further reductions to SNAP and other nutrition support programs are also on the table. These aren't just numbers on a spreadsheet. These are lifelines. Vital services that help children survive and thrive. When families can't afford formula, when clinics lose funding for immunization programs, when children lose health coverage, the consequences are immediate and, in many cases, irreversible. As front-line providers, we witness this every day. We can do better. Our federal budget is a reflection of our national values. It should not balance its books on the backs of our youngest and most vulnerable. I implore Wisconsin's elected officials to reject this harmful budget proposal. Think of that infant in the emergency room. Think of the thousands of other children across our state whose health and future depend on robust public health infrastructure, access to care, and support for families in need. We urge lawmakers to work toward a bipartisan budget that invests in children, strengthens public health, and protects the building blocks of a healthy society. Wisconsin's children deserve every opportunity to grow up healthy and strong. Our chapter of the National Association of Pediatric Nurse Practitioners stands ready to partner in this effort. Let's move forward — not backward — when it comes to the health of our children. Christine Schindler is a critical care pediatric nurse practitioner at Children's WI, a clinical professor at Marquette University, and the President of the Wisconsin Chapter of Pediatric Nurse Practitioners. She has been caring for critically ill and injured children for almost 30 years. All opinions expressed are her own.

4 Quick And Healthy Breakfasts With 30g Of Protein
If you know you need to eat more protein but aren't sure where to start, breakfast is a good place. Eating a sizeable portion of your daily protein goal first thing not only ticks a box early, it also helps to curb energy slumps, sugar cravings, and sluggishness later in the day. Current guidelines recommend 0.75g of protein per kilogram of body weight per day, but this number can change depending on your age and lifestyle. For example, if you strength train regularly or have an active job, this number may increase. If you're older and more sedentary, it'll decrease. 'Eating a healthy portion of protein for breakfast can help balance blood sugar and energy,' says nutritionist and founder of Artah, Rhian Stephenson, who tends to recommend closer to 1.2g of protein per kilogram of bodyweight to her clients. 'Plus, studies have shown that front-loading your day with adequate protein improves satiety and decreases appetite throughout the day.' Consider us persuaded. Here are four simple high-protein breakfast recipes to incorporate into your morning routine. 1. High-protein yogurt bowl Nutritionist and functional medicine practitioner Farzanah Nasser eats this high-fiber, high-protein breakfast most mornings. 'This recipe hits 30g of protein and 13g of fiber, which is almost half of the daily recommended amount. It also contains two sources of probiotics (which help maintain a healthy gut microbiome), and will keep you full until lunchtime—no energy crashes in sight.' Ingredients 150g 0% fat Greek yogurt ¼ to ½ cup kefir 20g shelled hempseed 20g ground flaxseeds 1 tsp chia seeds 1 heaped tsp oats 1 heaped tsp almond butter Fruit of choice Optional: honey Method Add the yogurt, kefir, hempseed, flaxseeds, chia seeds, and oats into a bowl and mix well. Then top with your fruit of choice (Nasser likes one kiwi fruit) and a drizzle of almond butter and honey. 2. High-protein spinach scramble 'This satisfying breakfast is quick to make and provides a healthy dose of protein to start the day,' says Lingo by Abbott's resident nutritionist, Sophie Bertrand. 'Eggs are rich in a variety of nutrients, including vitamins A, B12, E, as well as choline, zinc, and selenium. The spinach adds beneficial antioxidants and fiber, too.' Ingredients 3 large eggs ¼ cup low-fat cottage cheese ½ cup fresh spinach 1 tsp olive oil Salt and pepper to taste Optional: 1 tbsp chia or hemp seeds Method Heat a pan over medium heat and add the olive oil. Crack the eggs into a bowl and whisk them until the yolks and whites are well combined. Pour the eggs into the pan and cook, stirring gently, until they begin to set but are still slightly runny. Add the cottage cheese and spinach to the eggs and continue cooking, stirring occasionally, until the eggs are fully scrambled and the spinach has wilted. Season with salt and pepper to taste, and sprinkle in chia or hemp seeds if using. Serve immediately and enjoy. 3. High-protein peach smoothie 'This 'springtime in a glass' smoothie not only delivers more than 30g of protein—thanks to the protein powder—but the hemp seeds and nut butter support everything from blood sugar balance to muscle recovery and neurotransmitter health,' says naturopathic nutritionist and hormone specialist Jessica Shand. 'The maca root powder helps with energy and hormone balance, while the bee pollen supports immunity, and the fruit is rich in antioxidants.' Ingredients 200ml organic kefir 50ml unsweetened almond milk 1 scoop protein powder 1 tsp maca powder 1 tbsp bee pollen 1 peach 1 cup frozen raspberries ½ cup frozen avocado ½ cup frozen mango 2 tbsp hemp seed 1 tbsp nut butter Method Add all ingredients to your blender and blitz until smooth. 4. High-protein vegan eggs on toast 'Tofu is a minimally processed product made from soya beans and is an excellent source of protein with good amounts of all nine essential amino acids,' explains plant-based nutritionist Rohini Bajekal. 'This recipe is also rich in herbs and spices, which are the most antioxidant-rich of all food groups. When you use them in dishes, it tends to reduce the desire for excess salt, oil, and sugar.' This recipe pairs well with sourdough or rye bread, says Bajekal, but you could also pop it into a wrap for a portable version. Ingredients 150g firm tofu (15g protein 50g chickpea flour (10g protein) 30g spinach (1g protein) 2 tbsp nutritional yeast (4g protein) 1 slice wholemeal bread (3g protein) ¼ avocado 1 tbsp olive oil ½ small onion, diced ¼ bell pepper, diced ½ tsp turmeric ¼ tsp paprika ¼ tsp cumin Optional: ¼ tsp black salt Salt and pepper to taste Fresh herbs such as basil for garnish Method
