Avoid Deadly Blood Clots with Two Natural Extracts

The AHA! Team — Mon, 25 Aug 2025 05:27:07 +0000

Lori Alton via NaturalHealth365 – According to the Centers for Disease Control and Prevention (CDC), as many as 900,000 Americans could be affected by venous thromboembolisms (blood clots) every year – with roughly 100,000 dying from them. Believe it or not, the simple act of sitting – for long periods – may be hazardous to your health. The American College of Cardiology reports that sitting at a desk for more than four hours a day increases the odds of deep vein thrombosis by a frightening 48 percent. Deep vein thrombosis, or DVT, occurs when a blood clot forms in a vein located deep in the body. In a life-threatening complication, the clot may break loose and make its way to the lung, leading to a potentially fatal pulmonary embolism. Fortunately, recent research shows that you can combat DVT – safely and effectively – with the help of two natural extracts. Blood clots affect close to one million Americans According to the Centers for Disease Control and Prevention (CDC), as many as 900,000 Americans could be affected by venous thromboembolisms (blood clots) every year – with roughly 100,000 dying from them. In fact, the risks of prolonged sitting are so pronounced many are calling sitting “the new smoking.” In truth, Western medicine offers few real solutions. Anticoagulant medications prescribed by conventionally trained doctors can feature serious side effects – along with the risk of hemorrhage or uncontrolled bleeding. However, recent research shows that two natural substances, French maritime pine bark extract, and nattokinase, can break down small clots before they grow – and even stop them from forming in the first place. Both can inhibit clotting, improve microcirculation in the legs, and increase the elasticity of blood vessel walls. What are the symptoms and signs of a blood clot? Unfortunately, about half the time, there are no apparent signs of deep vein thrombosis. When symptoms occur, they tend to develop suddenly – and can include swelling, fatigue, tenderness, and pain in the affected leg. Reddened skin, otherwise discolored skin, and warm skin on one or both legs can also be warning signs. A previously invisible vein that suddenly becomes visible is also a red flag that may indicate a possible blood clot. Call your doctor if you notice any of these warning signs – especially if they develop suddenly. Of course, aging can make you more susceptible to blood clots – especially when living a sedentary lifestyle. Being obese, smoking cigarettes, having surgery, and taking oral contraceptives can also raise your risk. French maritime pine bark extract: A powerful natural vasodilator Pine bark extract, also known as pycnogenol, is rich in beneficial polyphenols, including procyanidins and phenolic acids. With potent antioxidant and anti-inflammatory properties, pine bark extract dilates blood vessels and reduces blood platelets’ stickiness, making them less likely to form clots. French maritime pine bark extract also increases the activity of an enzyme that generates beneficial nitric oxide in blood vessels. Several studies have demonstrated that pine bark extract is especially effective in preventing blood clots from forming after prolonged sitting. French maritime pine bark extract has also been shown to help reduce post-thrombotic syndrome, a common DVT complication in which blood collects in the affected leg and causes swelling, discoloration, and leg ulcers. In a year-long study, French maritime pine bark extract was found to be at least as effective as compression stockings in treating post-thrombotic syndrome. Not only did no new cases occur in the participants who took pine bark extract, but leg and ankle swelling was significantly decreased when compared to the compression stockings group. Researchers concluded that pine bark extract may have significant long-term protective effects following a thrombotic event. Another plus for French maritime pine bark extract is that compliance was better in the pine bark group. Researchers noted that taking the extract was not as “bothersome” to the participants as wearing the compression stockings, especially in warm weather. Nattokinase: A potent protector made from soy Nattokinase is a proteolytic enzyme made from soybeans fermented with a specific bacterium, Bacillus subtilis. It helps to prevent clotting by breaking down fibrin – the main protein found in clots – and also breaks down fibrinogen, the precursor to fibrin. It achieves this without causing side effects or undesirable bleeding. Nattokinase, combined with pine bark extract, has produced impressive results in studies. In a randomized, placebo-controlled human trial published in Angiology, passengers on a lengthy overseas flight were given either a placebo or a nattokinase and pine bark extract combination. The combination prevented each and every passenger who took it from experiencing DVTs. While there were zero DVTs in the supplement group, 5.4 percent of the passengers in the placebo group did experience DVTs. In contrast to the supplement group, passengers in the placebo group experienced a 12 percent increase in leg swelling during the flight – while supplemented passengers actually enjoyed a 15 percent reduction. The conclusion is that nattokinase and French maritime pine bark extract helped to prevent deep vein thrombosis in people who spent long periods sitting – thereby reducing the threat of sudden death from pulmonary embolism. If you must sit at a desk for prolonged periods, experts recommend getting up every hour and walking around for at least five to ten minutes to prevent blood from pooling in your legs. If interested, we suggest you discuss nattokinase and pine bark extract supplementation with your holistic healthcare provider. And, if they don’t know about these substances – find a doctor who understands the value of natural remedies.

How to Run Light on Your Feet & Avoid Injury

The AHA! Team — Wed, 23 Jul 2025 05:15:40 +0000

Joe Boland via Dr. Axe – Running is one of the best full-body aerobic exercises known to mankind, great for burning calories and working multiple muscle groups. Unfortunately, it also can lead to common running injuries, such as shin splints, stress fractures or heel spurs. The good news is there is research that may give runners a guide on how to run to avoid injury. A study published in the British Journal of Sports Medicine looked at why some longtime runners sustain many injuries while others never experience any injury at all. This is major, since up to 90 percent of runners sustain injuries that lead them to miss training time every year, according to some estimates. Conducted by folks at Harvard Medical School and other universities, the study involved 249 experienced female runners who were all heel strikers, meaning they all strike the ground with their heels when they run. Participants completed questionnaires about injury history and ran on a track with force monitors in order to measure impact loads. The runners were then tracked for two years, with the volunteers using a running diary and injury log during the study time. Over the two years, more than 140 runners reported sustaining injuries, with more than 100 of those injuries requiring medical attention. The other 100 or so reported no injuries, but of greater note to the researchers, 21 also had not had a prior injury either. To determine why this was the case, they turned to impact loading data, comparing the pounding metrics for those who have never been injured to those who have been seriously injured. Just as suspected, the runners who avoided injury landed far more lightly on their feet than those who had been seriously hurt. How to run light on your feet This is a huge breakthrough, since most runners are believed to be heel strikers. Turns out, this running technique does lead to more injuries because heel striking leads to a higher impact load on the foot, leg and body than landing near the middle or front of the foot. In fact, a 2012 study conducted by the Department of Human Evolutionary Biology at Harvard University and published in Medicine and Science in Sports and Exercise examined 52 runners, 36 of whom primarily used a rearfoot strike and 16 of whom primarily used a forefoot strike. Researchers found that “approximately 74 percent of runners experienced a moderate or severe injury each year, but those who habitually rearfoot strike had approximately twice the rate of repetitive stress injuries than individuals who habitually forefoot strike.” They ultimately concluded that “runners who habitually rearfoot strike have significantly higher rates of repetitive stress injury than those who mostly forefoot strike.” Another 2014 study published in the International Journal of Sports Physical Therapy also found that rearfoot striking puts more pressure on the lower limbs, particularly the ankles, than forefoot striking. So if you’re wondering how to run optimally to avoid injury, you want to focus on avoiding landing on your heel. Those findings reinforce what was found in this more recent study published in the British Journal of Sports Medicine. Dr. Irene Davis, the Harvard professor who led the study, said the findings also suggest that thinking about “a soft landing” can help. In addition, she provided some additional tips on how to run to avoid injury: Experiment with landing closer to the midfoot if you’re a heel striker. Most runners naturally land more lightly when they don’t lead with the heel. Slightly increase cadence — the number of steps you take per minute. This seems to reduce pounding from each stride. Imagine you’re running on eggshells or attempting to “run on water,” so to speak, trying to remain light on your feet. Davis’ Harvard colleague, professor Daniel E. Lieberman, had a few more tips on how to run properly as well: Don’t overstride. It places a big impact and shock wave that travels up your body. It also causes a deceleration of the body, so you have to work harder to keep your stride. If you focus on forefoot striking too much, you may overstride and cause more stress. Conversely, as we’ve noted, heel striking is bad. So focus on a flat-foot, midfoot strike. A very pronounced forefront or rearfoot strike is bad. Increase your stride rate. A high stride rate keeps your stride short and your bounce springy. Upright posture is important. If you lean forward, it puts big angular torque on your upper body, causing your body to want to fall forward, putting more stress on your lower body. Be relaxed. Don’t waste effort by tensing your upper body. If you’re a newer runner and wondering how to run from the get-go to avoid injury, keep these running tips for beginners in mind as well, in addition to this research: Warm up. Set a goal, and run consistently. Incorporate burst training. Cross-train. Get the right pre- and post-run fuel. Choose the right shoes. Watch out for uneven surfaces. Listen to your body. Stretch. Final thoughts Changing your running style is not necessarily easy, but it can really have an impact — no pun intended — on your injury incidence. Most people are heel strikers when they run, but this is actually detrimental and leads to more injury. Numerous studies have confirmed this, noting that rearfoot strikers put more impact and strain on their limbs than midfoot or forefoot strikers. Seeing as running injuries are so common and can interfere with exercise and training, it’s wise to focus on your running technique. Here are some tips on how to run with proper running technique by staying light on your feet to avoid injury: Warm up. Set a goal, and run consistently. Incorporate burst training. Cross-train. Get the right pre- and post-run fuel. Choose the right shoes. Watch out for uneven surfaces. Listen to your body. Stretch. Think about a soft landing. Focus on landing closer to your midfoot. Slightly increase your cadence, and potentially shorten your stride. Try imagining you’re running on eggshells or attempting to run on water to remain light on your feet. Don’t overstride. Land flat-footed or close to it. Run with upright posture. Be relaxed. To read the original article click here.

7 Science-Backed Strategies to Curb Summertime Carb Cravings

The AHA! Team — Mon, 21 Jul 2025 05:26:29 +0000

Dr. Don Colbert – As the mercury climbs, so too can our hankering for cold beers, sugary smoothies, and carb-heavy treats. Left unchecked, these cravings can derail even the best intentions. Fortunately, research offers clear, practical tactics to keep those impulses in check—so you can enjoy the season without sacrificing your health. Below, you’ll find seven science-backed strategies (and real-world stats) to help you stay on track all summer long. 1. Stay Hydrated-Thirst Often Masquerades as Hunger Why it works: Dehydration blunts your satiety signals, making you more likely to reach for quick-energy carbs. A landmark study from the University of Birmingham found that drinking 500 mL of water 30 minutes before a meal led participants to consume 75–90 fewer calories, on average, compared to those who drank no water beforehand (Stookey et al., 2012). Dr. Colbert’s tip: Keep a tall glass or reusable bottle by your side. Aim for 8–10 cups of water daily—and chug 8 oz before each meal. On hot days, mineral-rich sparkling water or herbal iced teas count, too. 2. Pack in the Fiber-Slow Digestion, Slower Cravings Why it works: Fiber not only bulks up your meals but also slows carbohydrate absorption, flattening blood sugar spikes that trigger rebound cravings. A meta-analysis in the Journal of Nutrition showed that for every additional 10 g of fiber consumed daily, people eat 130 fewer calories overall (Clark & Slavin, 2013). Dr. Colbert’s tip: Reach for fresh berries, peaches with skin, chilled edamame, or a big mixed-green salad topped with chickpeas or black beans. An extra 5–10 g of fiber at lunch can make all the difference by afternoon. 3. Use Targeted Supplements-Your “Craving Blockers” Why it works: Certain supplements can blunt carb absorption or support insulin sensitivity. For example, white bean extract (Phaseolus vulgaris) has been shown to reduce post-meal blood glucose by up to 20% (Udani et al., 2004), while medium-chain triglyceride (MCT) oil can boost ketones and promote satiety (St-Onge & Bosarge, 2008). Dr. Colbert’s tip: Try 500 mg of a clinically studied carb-blocking formula with your largest carb meal. Or stir 1 Tbsp MCT oil into your morning smoothie—just be sure to ease in (start with 1 tsp) to avoid digestive upset. 4. Practice Mindful Eating-Savor Every Bite Why it works: Distracted eating (TV, phones, driving) disconnects you from your body’s fullness cues, often leading to over-consumption of high-glycemic foods. In controlled trials, mindful eaters consume 25% fewer calories at lunch and report greater post-meal satisfaction (Kristeller & Wolever, 2011). Dr. Colbert’s tip: Eat without screens. Take at least 20 minutes per meal, pause between bites, and rate your hunger on a 1–10 scale before and after eating. When your score hovers around 3–4, it’s time to stop. 5. Leverage “If-Then” Planning-Outsmart Your Impulses Why it works: Implementation intentions (“if-then” plans) turn good intentions into action. A seminal review in Psychological Bulletin found that people who set specific if-then rules (e.g., “If I feel a sugar craving, then I’ll chew sugar-free gum”) are 300% more likely to follow through than those with vague goals (Gollwitzer & Sheeran, 2006). Dr. Colbert’s tip: Write down two personalized plans before the weekend: If I crave chips while watching TV, then I’ll munch on air-popped popcorn. If I’m tempted by an ice-cream truck, then I’ll drink a sparkling probiotic water first and re-assess. 6. Prioritize Protein & Healthy Fats-Cravings’ Natural Opponents Why it works: Protein and fats slow gastric emptying and stimulate satiety hormones (GLP-1, CCK). In one study, subjects who ate 30 g of protein for breakfast had 60% fewer cravings mid-morning compared to a carb-heavy meal (Leidy et al., 2015). Dr. Colbert’s tip: Upgrade your BBQ sides—swap potato salad for a Greek yogurt-based tzatziki dip with veggies, or add grilled salmon to your greens. At snack time, reach for a handful of almonds, a hard-boiled egg, or guacamole with cucumber slices. 7. Optimize Sleep & Stress Management—Tame the Hormones Why it works: Poor sleep elevates ghrelin (the “hunger hormone”) and lowers leptin (the “I’m full” hormone), driving carb cravings by up to 30% (Spiegel et al., 2004). Chronic stress spikes cortisol, which also promotes sugar-seeking behavior. Dr. Colbert’s tip: Aim for 7–8 hours of shut-eye nightly. Wind down with a tech-free ritual (reading, gentle yoga, magnesium bath). When stress hits, try a 5-minute breathing break (inhale for 4 counts, exhale for 6)—research shows it can drop cortisol by 20% in under 10 minutes (Jerath et al., 2006). Wrapping Up Summertime shouldn’t mean submitting to carb cravings. By staying hydrated, loading up on fiber, using smart supplements, eating mindfully, planning ahead with if-then strategies, prioritizing protein/fats, and safeguarding your sleep and stress levels, you’ll not only beat cravings but also sustain energy, focus, and overall well-being. Fun fact: Americans, on average, eat just 16 g of fiber daily—far below the recommended 25–30 g. Boosting even 5 g can dramatically improve appetite control and gut health (USDA, 2020). Ready to take control? Pick one strategy this week, track your progress, and savor the health (and confidence) that comes with powering through summer—carb cravings and all.

An Ideal BMI

The AHA! Team — Fri, 18 Jul 2025 05:15:35 +0000

Michael Greger M.D. FACLM via Nutrition Facts – Is there a unisex chart for optimal weight based on height? We seem to have become inured to the mortal threat of obesity. If you go back in the medical literature almost a quarter of a century ago when obesity wasn’t run-of-the-mill, the descriptions are much grimmer: “Obesity is always tragic, and its hazards are terrifying.” Not just obesity, though. Of the four million deaths attributed to excess body fat each year, nearly 40 percent of the victims are overweight, not obese. According to two famous Harvard studies, weight gain of as little as 11 pounds (5 kg) from early adulthood through middle age increases the risk of major chronic diseases, such as diabetes, cardiovascular disease, and cancer. The flip side, though, is that even modest weight loss can have major health benefits. What is the optimal body mass index, commonly known as BMI? The largest studies in the United States and around the world found that having a BMI of 20 to 25 is associated with the longest lifespan. Put all the best available studies with the longest follow-up together, and that can be narrowed down even further to a BMI of 20 to 22. That would be about 124 to 136 pounds (56 to 62 kg) for someone who’s five-foot-six (168 cm), as you can see below and at 1:22 in my video What’s the Ideal BMI?. Even within a “normal” BMI range, the risk of developing chronic diseases, such as type 2 diabetes, heart disease, and several types of cancer, starts to rise towards the upper end—starting as low as a BMI of 21. BMIs of 18.5 and 24.5 are both considered to be within the “normal” range, but a BMI of 24.5 may be associated with twice the risk of heart disease compared to a BMI of 18.5. Below and at 2:05 in my video is a graph of diabetes risk and BMI among women. There is a fivefold difference in diabetes rates within the so-called ideal range with a BMI under 25. Just as there are gradations of risk within a normal BMI range, there is a spectrum within obesity. Class III obesity (BMI over 40) can be associated with the loss of a decade or more of life. At a BMI above 45, for example, a person standing at 5’6″ (168 cm) and weighing 280 pounds (127 kg), life expectancy may shrink to that of a cigarette smoker. Skeptics have argued However, “skeptics have argued that the consequences of rising obesity levels have either been greatly exaggerated or are unclear.” A “motley crew,” “obesity skeptics are made up of a kaleidoscope of interest groups…includ[ing] feminists, queer theorists, libertarians, far right-wing conspiracy types and new ageists.” It “has also been popular on far right-wing, pro-gun, pro-America websites where the idea that obesity alarmists are nanny-state communists who simply want to stop us from having fun plays well….” Less treatment of the problem Unlike activists who organized to raise consciousness and stamp out the AIDS epidemic, for example, some in the size acceptance movement appear to have the opposite goal and “have called for less public awareness and intervention regarding obesity,” less treatment of the problem. I’m all for fighting size stigma and discrimination—I have a whole section on weight stigma in my book How Not to Diet—but the adverse health consequences of obesity are an established scientific fact. Can’t you be fat but fit? In a study of more than 600 centenarians, only about 1 percent of the women and not a single one of the men were obese. There does appear to be a rare subgroup of individuals who are obese and do not suffer the typical metabolic costs, such as high blood pressure and cholesterol. This raises the possibility that there may be such a thing as “benign obesity” or “metabolically healthy obesity.” It may just be a matter of time, though, before the risk factors develop. Even if they don’t, though, when followed long enough, even “metabolically healthy obese adults” are at increased risk of diabetes, as well as increased risk of fatty liver disease. They are also at greater risk of cardiovascular events, such as heart attacks, and/or premature death, as shown below and at 4:20. Bottom line? There is “strong evidence that ‘healthy obesity’ is a myth.” Many “fat activists” try to downplay the risks of obesity, even as they may be among “the greatest victims” of the epidemic. “Leading fat acceptance activist Lynn McAfee, who is director of medical advocacy for the Council on Size and Weight Discrimination and takes part in obesity conferences and government panels on obesity,” is quoted as saying, “‘I’m not actually particularly that interested in [health] and God I hate science….” If you missed the previous blog posts in this series on obesity, see related posts below. The final video in this series is What’s the Ideal Waist Size?. Key Takeaways Nearly 40 percent of the four million deaths linked to excess body fat annually are among people who are overweight, not just obese, showing the widespread health risks. Even small reductions in body weight can significantly improve health outcomes, reducing the risk of chronic diseases like diabetes, heart disease, and cancer. The optimal BMI for longevity is between 20 and 22, with risks for diseases increasing even within the “normal” BMI range, especially towards the upper end. Some groups, including far-right and size acceptance activists, downplay or deny the health risks of obesity, despite overwhelming scientific evidence linking it to serious health issues. Although some individuals may appear metabolically healthy while obese, long-term studies show that they still face heightened risks of conditions like diabetes, fatty liver disease, and heart attacks, debunking the idea of “healthy obesity.” To read the original article click here.

Sip Your Way to Better Health: The Secret Drink that Could Transform Your Metabolism

The AHA! Team — Mon, 14 Jul 2025 05:56:45 +0000

Patrick Tims via NaturalHealth365 – Think your metabolism is just about the genes you inherited? New research suggests otherwise. Scientists at Washington State University recently published findings in Nutrients that challenge this common belief. Their study points to something interesting: elderberry juice might help rev up your metabolism. While it might sound surprising, this dark purple juice does more than just taste good – it seems to boost your metabolism and could even help you maintain a healthy body weight. The research behind the surprising benefits of elderberry juice This wasn’t just any quick study – researchers at Washington State University conducted a carefully controlled, 5-week crossover trial to understand what elderberry juice could do. The findings are particularly interesting because obesity affects over 70% of adults in the United States, and we’re always looking for natural ways to help. Here’s how they did it: They gathered 18 adults with higher BMIs (over 25 kg/m²) who were otherwise healthy and had them drink either elderberry juice or a matching placebo for a week, took a break, and then switched drinks. What makes this study solid is that they controlled participants’ diets (40% fat diet) for 4 days during each test period to ensure accurate comparisons. Each participant drank about 12 ounces (177.5 grams) of elderberry juice daily, which delivered about 720 mg of beneficial compounds called cyanidin-3-glucoside equivalents. How elderberry juice improves your metabolism The study revealed some fascinating changes in participants’ bodies. At the most basic level, the juice shifted their gut bacteria, increasing helpful bacteria like Bifidobacterium and Faecalibacterium while reducing less beneficial types. This matters because gut bacteria are crucial in how the body processes nutrients. Most notably, the elderberry juice improved how participants’ bodies handled sugar and fat. When testing blood sugar levels after meals, researchers saw significant improvements in glucose control. Participants’ insulin levels dropped by nearly 10%, suggesting their bodies were becoming more efficient at processing sugar. Perhaps most impressively, the juice enhanced participants’ ability to burn fat – a process called fat oxidation after meals and during exercise. The data showed a remarkable 27% increase in fat burning among those drinking elderberry juice. Tips to implement elderberry juice into your daily meals While elderberry juice, native to Europe, might not be available at your local store, you can likely find it at a nearby health food store. You can also purchase it online. Many enjoy elderberry juice “straight” in a glass or mixed with water, seltzer, or tonic. It also works well blended into smoothies for a metabolic boost.

Exploring the Obesity Paradox

The AHA! Team — Fri, 11 Jul 2025 05:24:39 +0000

Michael Greger M.D. FACLM via Nutrition Facts – How do we explain studies that suggest overweight individuals live longer? Martin Luther King Jr. warned that human progress is neither automatic nor inevitable, and the same may be true of the human lifespan. In the 1800s, life expectancy was less than 40 years, but it has been “advancing steadily” over the last two centuries, “increasing at approximately 2 years per decade”—until recently. Longevity gains appear “to be faltering or even being reversed.” Thanks to the obesity epidemic, we may now be raising the first generation to live shorter lives than their parents. A downward trend in longevity “This downward trend in longevity will almost certainly accelerate as the current generation of children—with higher body weights from earlier in life than ever before—reaches adulthood.” Current trends “potentially signal a looming social and economic catastrophe” if the obesity epidemic continues unchecked. In the coming decades, some predict we may lose two to five years or more of life expectancy in the United States. To put that into perspective, a miracle cure for all forms of cancer would only add three and a half years to the average U.S. life expectancy. In other words, reversing the obesity epidemic might save more lives than curing cancer. The evidence that being overweight increases our risk for debilitating diseases like diabetes is considered “indisputable.” However, surprisingly, there is controversy surrounding body weight and overall mortality. In 2013, scientists with the Centers for Disease Control and Prevention (CDC) published a meta-analysis in the Journal of the American Medical Association suggesting that being overweight was advantageous. Grades 2 and 3 obesity, such as being an average height of 5’6″ and weighing about 216 pounds (98 kg) or more, were associated with living a shorter life, but grade 1 obesity, weighing about 185 to 215 pounds (84 to 97 kg) at that height, was not. Being overweight (about 155 to 185 pounds/70 to 83 kg at 5’6″) appeared to be protective compared to those who were a “normal weight” of 115 to 155 pounds (52 to 69 kg). The overweight individuals, those with a body mass index (BMI) of 25 to 30, appeared to live the longest. Headline writers were giddy. “Being overweight can extend your life rather than shorten it,” read one. “Dreading your diet? Don’t worry—plump people live LONGER than their skinnier counterparts…” read another. “Extra pounds mean a lower chance of death.” Not surprisingly, the study ignited a firestorm of controversy in the public health community. The study was called “ludicrous,” “flawed,” and “misleading.” The chair of nutrition at Harvard lost his cool, calling the study “really a pile of rubbish” and fearing the food industry might exploit the study in the same way the petroleum industry misuses “controversy” over climate change. Public health advocates can’t just dismiss data they find inconvenient, though. Science is science. But how could being overweight increase the risk of life-threatening diseases, yet, at the same time, make you live longer? This became known as “The Obesity Paradox,” the subject of my video Is the Obesity Paradox Real or a Myth?. The solution to the puzzle appears to lie with two major sources of bias, the first being “confounding by smoking.” The nicotine in tobacco can lead to weight loss. So, if you’re skinnier because you smoke, then no wonder you’d live a shorter life, albeit with a slimmer waist. The failure to control for the effect of smoking in studies purporting to show an “obesity paradox” leads to the dangers of obesity being “grossly underestimated.” The second major source of bias is reverse causality. Instead of lower weight leading to life-threatening diseases, isn’t it more likely that life-threatening diseases lead to lower weight? Conditions such as hidden tumors, chronic heart or lung disease, alcoholism, and depression can all cause unintentional weight loss for months or even years before they are even diagnosed. It’s normal to be overweight in the United States, for example. So, people who are “abnormally” thin—in other words, at an ideal weight—may be taking care of themselves, but they may instead be “heavy smokers, frail and elderly, and seriously ill with weight loss due to their disease…” To put the obesity paradox to the test once and for all, The Global BMI Mortality Collaboration was formed, reviewing data from more than 10 million people from hundreds of studies in dozens of countries—the largest evaluation of BMI and mortality in history. To help eliminate bias, the researchers omitted smokers and those with known chronic disease, then excluded the first five years of follow-up to try to remove from the analysis those with undiagnosed conditions who lost weight due to an impending death. And? The results were clear: “This analysis has shown that both overweight and obesity (all grades) were associated with increased all-cause mortality”—a greater risk of dying prematurely. So, “adjusting for these biases leads to eliminating the obesity paradox.” In other words, the so-called obesity paradox appears to be “just a myth.” Indeed, when intentional weight loss is put to the test, people live longer. There are bariatric surgery studies like the SOS trial that show that weight loss reduces long-term mortality, and randomizing study participants to weight loss through lifestyle changes shows the same thing. Losing a dozen pounds through diet and exercise was found to be associated with a 15 percent drop in overall mortality. Now, exercise alone may extend lifespan even without weight loss, but there appears to be a similar longevity benefit of weight loss through dietary means alone.

Why are people obese in the first place? I have a whole series of videos on that topic. Check the videos in the related posts. Key Takeaways Rising obesity rates may lead to shorter life expectancy for future generations, reversing centuries of progress in longevity. Studies suggesting that being overweight might extend life were biased due to confounding factors like smoking and reverse causality (diseases causing weight loss), and later analysis disproved the so-called obesity paradox. A large-scale review showed that both overweight and obesity are linked to a higher risk of premature death, contradicting earlier claims of protective benefits from being overweight. Intentional weight loss, whether through lifestyle changes or bariatric surgery, is associated with lower mortality rates and improved long-term health outcomes. Tackling obesity may have a greater impact on life expectancy than even a hypothetical cure for all cancers, highlighting obesity’s significant health risks. To read the original article click here.

Top 10 Scientifically Studied Foods & Habits for Men to Live to 100

The AHA! Team — Fri, 11 Jul 2025 05:10:26 +0000

Dr. Don Colbert – Let’s explore 10 scientifically backed dietary habits and food choices that can help men live not only longer—but better. In today’s fast-paced world, many men are chasing success while unknowingly shortening their lifespan through daily choices. The good news? Science is revealing specific foods and habits that consistently promote longevity—especially for men. At DrColbert.com, we believe a long life should be filled with strength, clarity, purpose, and faith—not just extra years on a calendar. Let’s explore 10 scientifically backed dietary habits and food choices that can help men live not only longer—but better. 1. Olive Oil (Extra Virgin) A source of heart and brain protection. Extra virgin olive oil (EVOO) is one of the most studied and proven longevity foods in the world—especially for men. A 2022 study published in the Journal of the American College of Cardiology found that men who consumed just half a tablespoon of olive oil daily had a significantly lower risk of death from cardiovascular disease, neurodegenerative disease (such as Alzheimer’s and Parkinson’s), and even cancer. Why is EVOO so effective? The answer lies in its high concentration of monounsaturated fats and polyphenols—natural plant compounds with anti-inflammatory and antioxidant properties. These compounds help reduce oxidative stress, which plays a key role in aging, chronic disease, and hormone decline in men. For cardiovascular health, EVOO improves blood lipid profiles, supports flexible blood vessels, and helps prevent arterial plaque buildup. This is especially critical for men, who are statistically at higher risk of heart attacks and strokes—often earlier in life than women. But the benefits go beyond the heart. The brain thrives on healthy fats, and the polyphenols in EVOO protect neurons, reduce brain inflammation, and support memory, mood, and cognitive performance. Some studies have even suggested EVOO may reduce the risk of developing Alzheimer’s disease—conditions that disproportionately affect men in later decades. In men over 40, regular consumption of EVOO has also been linked to healthier testosterone levels and improved insulin sensitivity—both essential for energy, libido, metabolism, and weight control. How to use it: Drizzle on salads, cooked vegetables, or mix with herbs as a dipping oil. Always use cold-pressed extra virgin olive oil to preserve the polyphenols and beneficial fats. Avoid using it for high-heat cooking—opt instead to finish your dishes with it or use it in dressings, dips, and marinades. Adding just 1–2 tablespoons a day can yield long-term benefits for brain clarity, heart function, and hormone balance—making EVOO a foundational food in any man’s longevity plan. 2. Fatty Fish (Wild-Caught Salmon, Sardines, Mackerel) Omega-3 rich foods that reduce inflammation and protect the heart. The NIH Atherosclerosis Risk in Communities (ARIC) study found that men with higher blood levels of omega-3s had lower risk of death from all causes, particularly heart disease. Target: 2–3 servings per week of wild-caught fish like salmon or sardines. Omega-3 fatty acids, prominently found in wild-caught fatty fish like salmon, sardines, and mackerel, play a pivotal role in maintaining men’s overall health, particularly cardiovascular and cognitive function. Omega-3s—specifically EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid)—have been scientifically proven to reduce inflammation throughout the body, which is crucial as chronic inflammation underpins many common chronic diseases, including heart disease, arthritis, and even certain cancers. Research, such as the NIH Atherosclerosis Risk in Communities (ARIC) study, has consistently shown that men with higher blood levels of omega-3 fatty acids experience significantly reduced mortality rates from heart disease. These nutrients actively support heart health by improving cholesterol profiles, lowering blood pressure, and reducing the formation of arterial plaques, thereby protecting arteries from becoming stiff and narrowed. Additionally, omega-3 fatty acids are vital for brain health and cognitive longevity. They support neuronal function, enhance memory, improve mood stability, and have been linked to a lower risk of developing neurodegenerative diseases like Alzheimer’s and Parkinson’s. Moreover, fatty fish provides high-quality protein and vitamin D, nutrients essential for maintaining muscle mass, bone density, and hormonal balance—key factors in men’s health, particularly as they age. For optimal benefits, aim for 2–3 servings of wild-caught fish weekly, prioritizing sources known for low mercury levels, to maximize omega-3 intake without unwanted contaminants. 3. Cruciferous Vegetables (Broccoli, Kale, Brussels Sprouts) Cancer-fighting and hormone-balancing foods. A 2015 study linked regular consumption of cruciferous vegetables to a lower risk of prostate cancer. These vegetables support estrogen balance and detoxification. Tip: Lightly steam or sauté to preserve nutrients. Add lemon or olive oil to boost absorption. 4. Berries (Blueberries, Strawberries, Raspberries) Brain and cardiovascular protection through flavonoids. A 2020 Harvard study from the Framingham Heart Study found that men who consumed higher levels of flavonoids from berries had a reduced risk of cognitive decline and cardiovascular disease. Serving idea: Add to smoothies, Greek yogurt, or eat as a midday snack. 5. Nuts (Especially Walnuts, Almonds & Brazil Nuts) Heart healthy and inflammation-lowering. The Adventist Health Study showed that men who ate nuts five or more times a week lived 2–3 years longer than those who didn’t. Portion guide: 1 small handful per day (unsalted, raw or dry roasted). 6. Green Tea Lowers cardiovascular risk and supports metabolism. The Ohsaki Cohort Study involving over 40,000 men found that those who drank green tea daily had significantly lower risk of death from heart disease and stroke. Tip: Drink 2–3 cups daily. Avoid extracts in high doses. 7. Fermented Foods (Sauerkraut, Kimchi, Greek Yogurt, Kefir) Support gut health and immune resilience. A 2021 study in Cell found that a diet high in fermented foods increased microbiome diversity and lowered inflammation markers like IL-6 and CRP. Daily serving: 1–2 small servings of natural, unpasteurized fermented foods. 8. Intermittent Fasting (IF) Improves insulin sensitivity and cellular repair. A landmark study in The New England Journal of Medicine supports time-restricted eating (e.g., 16:8) for weight loss, blood sugar control, reduced inflammation, and longevity. How it works: Fast for 16 hours (e.g., 8 pm to noon) and eat within an 8-hour window. 9. Mediterranean Diet (Modified with Low-Carb Principles) The most studied longevity diet in the world. A 2018 Lancet review confirmed that men following this pattern had lower risk of premature death. Dr. Colbert recommends a modified Mediterranean-Keto Zone approach—low in carbs but high in healthy fats and greens—to maximize results. 10. Faith-Fueled Eating & Gratitude Promotes emotional well-being and digestion. Studies show that gratitude before meals lowers cortisol and improves digestion. Eating slowly, being present, and giving thanks aligns with 1 Timothy 4:4–5: “For everything God created is good, and nothing is to be rejected if it is received with thanksgiving…” To read the original article click here.

Cold Water Immersion Boosts Cellular Health & Resilience

The AHA! Team — Wed, 04 Jun 2025 05:46:52 +0000

University of Ottawa via News-Medical – Ever wondered what happens to your body when you take those trendy ice baths? Scientists at the University of Ottawa just found out, and it’s pretty fascinating. New Study A new study conducted at the Human and Environmental Physiology Research lab (HEPRU) at the University of Ottawa has unveiled significant findings on the effects of cold water acclimation on autophagic (the cells’ recycling system, which promotes cellular health) and apoptotic (the programmed cell death that gets rid of damaged cells) responses in young males. The research highlights the potential for cold exposure to enhance cellular resilience against stress. The study, conducted by Kelli King, postdoctoral fellow, and Glen Kenny, Full Professor at uOttawa’s School of Human Kinetics and Director of HEPRU, involved ten healthy young males who underwent cold-water immersion at 14°C (57.2°F) for one hour across seven consecutive days. Blood samples were collected to analyze the participants’ cellular responses before and after the acclimation period. Findings “Our findings indicate that repeated cold exposure significantly improves autophagic function, a critical cellular protective mechanism,” says Professor Kenny. “This enhancement allows cells to better manage stress and could have important implications for health and longevity.” The research revealed that while autophagy was initially dysfunctional after high-intensity cold stress, consistent exposure over a week led to increased autophagic activity and decreased cellular damage signals. By the end of the acclimation, we noted a marked improvement in the participants’ cellular cold tolerance. This suggests that cold acclimation may help the body effectively cope with extreme environmental conditions.” – Kelli King, postdoctoral fellow, study’s first author The implications of this study extend beyond athletic performance. Cold water immersion has gained popularity for its potential health benefits, and this research provides some scientific backing for its efficacy. The findings suggest that proper autophagic activity could not only extend cellular longevity but also prevent the onset of various diseases. As the use of cold exposure becomes increasingly mainstream, understanding its effects on cellular mechanisms is vital. Professor Kenny emphasizes, “This work underscores the importance of acclimation protocols in enhancing human health, especially in contexts where individuals are exposed to extreme temperatures.” “We were amazed to see how quickly the body adapted,” notes King. “Cold exposure might help prevent diseases and potentially even slow down aging at a cellular level. It’s like a tune-up for your body’s microscopic machinery.” These results apply to young males and more research is needed to see if it would also apply to other cohorts.

Obesity’s Impact on Back Pain, Blood Pressure, Cancer, & Diabetes

The AHA! Team — Wed, 04 Jun 2025 05:26:48 +0000

Michael Greger M.D. FACLM via Nutrition Facts – Losing weight can reduce sciatica, hypertension, and cancer risk, as well as reverse type 2 diabetes. A is for Arthritis In the ABCs of the health consequences of obesity, A is for Arthritis, as I discussed in my previous blog post, and B is for Back Pain. Being overweight is not just a risk factor for low back pain, but it is also a risk factor for sciatica (a radiating nerve pain), as well as degenerating lumbar discs and disc herniation. Similar to what we learned in the arthritis story, this may also be due to a combination of the excess weight, high cholesterol, and inflammation associated with being overweight. Why cholesterol? Studies of autopsies and angiographies show that the lumbar arteries that feed our spine can get clogged with atherosclerosis and starve the disks in our lower back, as you can see below and at 0:47 in my video The Effects of Obesity on Back Pain, Blood Pressure, Cancer, and Diabetes. B is also for Blood Pressure. Excess visceral fat—for example, internal abdominal fat—can physically compress our kidneys. The increased pressure can effectively squeeze sodium back into our bloodstream, increasing our blood pressure. Together, the combination of obesity and hypertension can have “disastrous health implications,” but the good news is that just a few pounds of weight loss can help take off the pressure. Losing excess weight has been described as “a vital strategy for controlling hypertension.” In fact, researchers found that losing around nine pounds (4 kg) may lower blood pressure about as much as cutting salt intake approximately in half can. C is for Cancer. As many as three-quarters of people surveyed “were unaware that being overweight or obese increased a person’s risk of cancer,” when, in fact, based on a comprehensive review of more than a thousand studies, excess body fat raises the risk of most cancers, including esophageal, stomach, colorectal, liver, gallbladder, pancreatic, breast, uterine, ovarian, kidney, brain, thyroid, and bone marrow (multiple myeloma) cancers, as you can see below and at 2:00 in my video. It could be the chronic inflammation of obesity or perhaps it is the high insulin levels due to insulin resistance. (Besides controlling blood sugars, insulin is also “a potent growth factor” that can promote tumor growth.) In women, it could also be the excess estrogen. After the ovaries shut down at menopause, fat takes over as the principal site of estrogen production. That’s why women who are obese have up to nearly twice the estrogen levels circulating in their bloodstream, which is associated with an increased risk of developing breast cancer and dying from it. The data on prostate cancer aren’t as strong, though obesity is associated with increased risk of invasive penis cancer. Cause-and-Effect One of the reasons we’re confident the link between obesity and cancer is cause-and-effect—and not just an indirect consequence of eating poorly—is that the overall risk of cancer goes down when people lose weight, even through bariatric surgery. Researchers found that those experiencing a sustained weight loss of about 40 pounds (19.9 kg) after surgery went on to develop around one-third fewer cancers over the subsequent decade, compared with matched individuals in the nonsurgical control group who continued to slowly gain weight over time. The exception, though, is colorectal cancer. Colorectal cancer “Colorectal cancer is the only known malignancy where the risk of being diagnosed with disease seems to increase after obesity surgery.” Indeed, after bariatric surgery, the rate of rectal cancer death may triple. The rearrangement of anatomy involved in one of the most common surgeries—Roux-en-Y gastric bypass—is thought to increase bile acid exposure along the intestinal lining. This causes sustained pro-inflammatory changes even years after the procedure, which is thought responsible for the increased cancer risk. In contrast, losing weight by dietary means has the potential to decrease obesity-related cancer risk across the board. D is for Diabetes. As presented in a consensus statement from the International Diabetes Federation, obesity is considered the single most important risk factor for the development of type 2 diabetes, which is the leading cause of kidney failure, lower-limb amputations, and adult-onset blindness. Ironically, many of the leading drugs used to treat diabetes (including insulin itself) cause further weight gain, creating a vicious cycle. So, again, using lifestyle medicine to treat the underlying cause is not only safer, simpler, and cheaper, but can also be most effective.

I continue the topic of weight control with these videos that may be of interest to you: Is the Obesity Paradox Real or a Myth? and Friday Favorites: What’s the Ideal BMI and Waist Size?. For more on back pain, blood pressure, cancer, and diabetes, check out their topic pages. Key Takeaways Obesity increases the risk of low back pain, sciatica, and lumbar disc degeneration due to excess weight, high cholesterol, and inflammation, which may restrict blood flow to the spine, and the loss of even a few pounds, can help reduce blood pressure and prevent related health complications. Obesity raises the risk of many cancers, including breast, liver, and colorectal cancer, due to chronic inflammation, high insulin, and, in women, increased estrogen levels post-menopause. Weight loss, including through bariatric surgery, significantly lowers cancer risk, except for colorectal cancer, where the surgery may increase the risk due to bile acid exposure. Obesity is the primary risk factor for type 2 diabetes, which can lead to severe complications. Lifestyle changes targeting obesity can be more effective than medications, which may cause further weight gain. To read the original article click here.
