New pill cuts "bad" cholesterol by 60% in major trial
A new pill, enlicitide, reduced LDL ("bad") cholesterol by about 60% in a large clinical trial, matching the power of injectable therapies. Because it's taken orally, it could overcome one of the biggest barriers keeping patients from using current treatments. Researchers say many people still don't...
Huge study finds no evidence cannabis helps anxiety, depression, or PTSD
The largest review of medicinal cannabis to date found it doesn't effectively treat anxiety, depression, or PTSD-despite millions using it for those reasons. Researchers warn it could even make mental health worse, raising risks like psychosis and addiction while delaying proven treatments. Some lim...
What happens after Ozempic shocked researchers
Stopping popular weight-loss injections like Ozempic or Mounjaro might not trigger the dramatic rebound many fear. A large real-world study of nearly 8,000 patients found that most people who discontinue these drugs manage to keep the weight off-or even continue losing-by restarting treatment, switc...
Ultra-processed foods linked to 67% higher risk of heart attack and stroke
Eating large amounts of ultra-processed foods like chips, frozen meals, sugary drinks, and packaged snacks may significantly raise the risk of serious heart problems. In a major U.S. study, people consuming around nine servings per day had a 67% higher risk of heart attacks, strokes, or death from h...
Belly fat linked to heart failure risk even in people with normal weight
Carrying extra fat around the waist may be more dangerous than the number on the scale suggests. Researchers found that belly fat was more strongly linked to heart failure risk than BMI, even in people with normal weight. Inflammation seems to play a key role, helping explain why this type of fat is...
Cutting sweet foods doesn't reduce cravings or improve health
A new study suggests that eating less sweet food doesn't make people crave it any less-or improve their health markers. Participants who increased or decreased sweetness in their diets showed no changes in preferences, weight, or disease risk. Many even returned to their old eating habits over time....
You don't need to lose weight to reverse prediabetes, study finds
For years, people with prediabetes have been told the same thing: lose weight or risk developing diabetes. But new research flips that idea on its head, showing that blood sugar can return to normal even without shedding pounds. The key isn't just how much fat you carry-it's where it's stored. Harmf...
Your daily coffee may be protecting your brain, 43-year study finds
Your morning coffee or tea could be quietly supporting your brain health. A long-term study found that moderate consumption of caffeinated coffee or tea was linked to an 18% lower risk of dementia and better cognitive performance over time. The benefits appeared strongest at 2-3 cups of coffee or 1-...
Millions of kids take melatonin but doctors are raising red flags
Melatonin is now widely used to help children sleep, but scientists say the enthusiasm may be getting ahead of the evidence. A major review found clear benefits for children with conditions like autism and ADHD, yet far less data exists for typical childhood insomnia. Researchers also warn about mis...
Scientists tested vitamin D for COVID and found an unexpected long COVID clue
A major clinical trial has delivered an unexpected twist in the search for ways to fight COVID-19 and its lingering effects. Researchers at Mass General Brigham found that taking high doses of vitamin D3 did not make COVID-19 infections less severe or reduce hospital visits. However, the study uncov...
The financial crisis that quietly stunted a generation
When the Asian financial crisis sent rice prices soaring in Indonesia in the late 1990s, the shock didn't just strain household budgets-it left lasting marks on children's bodies. Researchers from the University of Bonn found that kids exposed to the food price surge were more likely to experience s...
How often do people really fart? Scientists built smart underwear to find out
Researchers have created "Smart Underwear," a wearable device that measures flatulence by detecting hydrogen produced by gut microbes. Early tests suggest people may pass gas about 32 times a day-much higher than previous estimates. The device gives scientists a new way to track gut microbial activi...
Microplastics may be quietly damaging your brain and fueling Alzheimer's and Parkinson's
Tiny plastic particles may be quietly threatening brain health. New research suggests microplastics-now widely found in food, water, and even household dust-could trigger inflammation and damage in the brain through multiple biological pathways. Scientists estimate adults may consume about 250 grams...
Scientists solve the mystery of a vitamin B5 molecule that powers your cells
Coenzyme A, a molecule derived from vitamin B5, is vital for metabolism throughout the body. Scientists discovered that most of it resides inside mitochondria, yet how it reached these cellular powerhouses was unclear. Yale researchers have now identified the transport system that moves CoA into mit...
Scientists found a surprising way to make exercise work better
Exercise normally boosts the body's ability to use oxygen, a key marker of health and longevity - but high blood sugar can block that benefit. Researchers found that a ketogenic diet helped mice normalize blood sugar and dramatically improved how their muscles responded to exercise. Their muscles be...
Popular pre-workout supplements linked to dangerous sleep loss
Pre-workout supplements promising extra energy for workouts may come with a hidden cost: severely reduced sleep. A study of people aged 16-30 found users were more than twice as likely to sleep five hours or less per night. Many of these products pack huge doses of caffeine and stimulants that can l...
Parents' stress may be quietly driving childhood obesity, Yale study finds
A Yale study found that lowering parent stress can help protect young children from obesity. When parents practiced mindfulness and stress-management skills, their kids showed healthier eating patterns and avoided the weight gain seen in families that only focused on diet and exercise.
Scientists say this simple diet change could transform your gut health
A growing trend called "fibermaxxing" is putting dietary fiber in the spotlight-and for good reason. Fiber plays a powerful role in keeping the body healthy, from supporting digestion and feeding beneficial gut microbes to helping regulate blood sugar and cholesterol. Researchers say getting enough ...
Popular fruits and vegetables linked to higher pesticide levels
A sweeping new study reveals that what's on your plate may directly shape the pesticides circulating in your body. Researchers found that people who eat more fruits and vegetables known to carry higher pesticide residues-such as strawberries, spinach, and bell peppers-also have significantly higher ...
Scientists just created chocolate honey packed with surprising health perks
Scientists in Brazil have transformed cocoa waste into a functional chocolate-infused honey packed with antioxidants and natural stimulants. Using ultrasound waves, they enhanced honey's ability to pull beneficial compounds from cocoa shells-no synthetic solvents required. The process is considered ...
