Garlic has been praised for centuries as one of those humble kitchen staples that seems to do more than simply flavor food. It shows up in family recipes, old home remedies, and now, increasingly, scientific studies looking at how natural compounds may affect the body as it ages. A new study suggests one particular compound found in aged garlic extract may have a surprising relationship with muscle health — and the path may run through fat cells. The research, summarized by StudyFinds and published in Cell Metabolism, focuses on a sulfur-containing compound called S-1-propenyl-L-cysteine, or S1PC. In laboratory and animal...

Creatine is often linked to gym performance, but its real impact goes much deeper. Creatine is widely recognized as a supplement used by athletes and fitness enthusiasts to improve performance. But its effects extend beyond the gym. Scientists have been studying how this naturally occurring compound influences both physical and mental function, revealing a more complex picture than many people expect. From supporting energy production to its possible role in future medical treatments, creatine continues to attract attention from researchers. Dr. Mehdi Boroujerdi, a pharmaceutical researcher and former professor, conducted a detailed review of creatine in the Handbook of Creatine...

(Photo credit: Exclusive Image for Unsplash+) Research Shows That Avoiding Eggs Entirely Linked To 22% Higher Risk Of Memory-Stealing Disease In A Nutshell People who ate eggs regularly had lower Alzheimer’s diagnosis rates over 15 years. The lowest risk appeared in those eating eggs five or more times per week. Eggs provide nutrients linked to brain health, including choline and vitamin B12. The study shows a connection, not proof that eggs prevent Alzheimer’s disease. Eggs have spent decades bouncing between dietary hero and villain, praised for their protein one year and vilified for their cholesterol the next. A new study...

Omega-3 supplements are popular among many older adults to help combat age-related issues. They are often marketed as supporting cardiovascular health and reducing the risk of cognitive decline and dementia. However, a new study published in The Journal of Prevention of Alzheimer's Disease suggests that these oral capsules may actually be linked to a faster decline in cognitive function. Many senior citizens swear by oral supplements and the benefits they bring. However, the scientific evidence is mixed. While animal and observational studies have indicated possible protective effects on the aging brain, controlled trials with humans have not shown such cognitive...

New research led by University College Cork scientists suggests that both caffeinated and decaf coffee reshape the gut microbiome in ways tied to lower stress and improved psychological well-being, offering clues to the drink’s long-suspected health effects. Coffee is a plant-derived beverage produced from processed coffee beans, with its flavor and chemical profile shaped by factors such as bean variety, ripeness, processing techniques, roasting, and brewing methods. It contains a range of bioactive compounds, including alkaloids like caffeine, polyphenols such as phenolic acids, diterpenes, and melanoidins formed during roasting. Moderate coffee consumption has been linked to a lower risk of...

Some people reach their 80s with memories sharper than many 50-year-olds. Scientists now think they know why: Their brains never stopped growing new cells. Scientists studying a rare group of older people known as superagers—those aged 80 and over whose memory rivals someone 30 years younger—have found that their brains produce new neurons at twice the rate of typical older adults. “For most of the last century, the prevailing belief was that brain cells only die as you age—you were born with what you had, and that was that,” Jordan Weiss, professor at the Optimal Aging Institute at NYU Grossman...

For years, turning 65 with a blood pressure reading above 130 meant one thing: medication. A new analysis of the 2025 American Heart Association guidelines shows that this practice is changing, finding that roughly 10 percent of older adults previously flagged for treatment may no longer meet the criteria, a move experts say prevents overtreatment, but one that carries its own risks. The 2025 guidelines marked a significant departure from the 2017 AHA guidelines, which recommended treatment for all adults over 65 with blood pressure at or above 130/80 mmHg. The updated 2025 guidelines replace that blanket approach with one...

Research suggests compounds in foods like blackberries and kale can influence brain chemistry tied to motivation and activity — another reminder that what we eat affects more than we realize.Key Takeaways: -A 2025 study suggests that astringent, flavanol-rich foods like berries and red wine may stimulate the nervous system through their puckering taste, potentially triggering physiological responses similar to moderate exercise. -In the study, mice given oral doses of flavanols exhibited increased physical activity, greater exploration, and improved learning and memory compared to a control group. -Researchers also observed elevated levels of dopamine, norepinephrine, and related compounds associated with motivation,...

A nasty new influenza variant — dubbed the “super flu” — is sweeping across the US, fueling a sharp rise in illnesses. So far this season, the CDC has logged 4.6 million flu cases, 49,000 hospitalizations and 1,900 deaths. SNIP In mainstream medicine, NAC’s uses are already well established. The FDA has approved it as the antidote for acetaminophen poisoning, helping prevent or reduce liver damage when given after an overdose. SNIP In an Italian study, researchers gave participants either a placebo or 600 milligrams of NAC twice daily for six months. By the end of the trial, 79% of...

Researchers tracked what happens when the vegetable’s natural compounds are activated during digestion, offering new insight into glucose metabolism.Key points: -Broccoli sprouts may be small, but they’re loaded with glucoraphanin — a nutrient that converts to sulforaphane, known for its antioxidant and anti-inflammatory effects. -Research shows they may help support healthy blood sugar levels, particularly in people with certain beneficial gut bacteria, such as Bacteroides and Bifidobacterium. -Since broccoli sprouts are usually eaten raw, they retain their active enzymes, allowing your body to fully activate their beneficial compounds. Wandering through the produce department, you might stumble upon broccoli sprouts —...

A paper published today in the journal Cell Reports Medicine offers new hope for an Alzheimer’s drug that doesn’t just slow cognitive decline but may reverse it. The study, by researchers at the University of Colorado Anschutz, found that Leukine or GM-CSF, a drug long-approved to treat other conditions, was able to stop brain cells from dying in Alzheimer’s patients when measured in a blood test. Brain cell death is a hallmark of Alzheimer’s disease. “The main thing that we found…is that the people who were treated with Leukine or GM-CSF actually lost the ability to kill their nerve cells…to...

Myocarditis from COVID-19 vaccines is caused by two chemicals acting together, according to a new Stanford study published on Wednesday. “As a cardiologist, we get asked all the time, ‘How exactly does [the vaccine cause myocarditis?]’” Dr. Joseph Wu, the study’s lead author and director of the Stanford Cardiovascular Institute, told The Epoch Times. “We thought it was a very important scientific and clinical question to spend resources [on] and tackle.” When an mRNA vaccine is given, immune cells release a surge of cytokines called CXCL10 and IFN-gamma, which damage heart muscles and cause immune cells to enter the injury...

Research in mice shows limited intakes of one particular essential amino acid can slow the impacts of aging and even lengthen their lifespan. Scientists are now wondering if these findings could help people improve their longevity and quality of life. Isoleucine is one of three branched-chain amino acids we use to build proteins in our bodies. It is essential for our survival, but since our cells can't produce it from scratch, we have to get it from sources like eggs, dairy, soy protein and meats. But there can always be too much of a good thing. Earlier research using data...

Human clinical trials reveal that black cumin has anti-obesity and heart-protective effects. Nigella sativa (black cumin) is best known as a flavorful spice used in dishes like korma and paneer, but it also has a long history in traditional medicine across South Asia, the Middle East, and North Africa. Practitioners have relied on the seeds for centuries, believing they support health through their antioxidant and anti-inflammatory properties. Modern science has begun to revisit these traditional claims, examining whether the plant’s bioactive compounds can meaningfully influence human metabolism. A team from Osaka Metropolitan University, led by Associate Professor Akiko Kojima-Yuasa of...

Skin cancer can be confusing…Firstly, any type of skin cancer is concerning. That’s why it’s important to pay attention to your skin and see a dermatologist at least once a year to see if any moles, freckles or growths are of concern.But some skin cancers have a much higher degree of risk for metastasizing, like melanoma. While melanoma is rare, accounting for only 1 percent of skin cancer cases, it represents the majority of skin cancer deaths.Then there are non-melanoma skin cancers, like basal cell carcinomas (BCC) and squamous cell carcinomas (SCC), the two most common types of skin cancer.Both...

A new study explores a radical idea: instead of killing cancer, what if we could heal it? In glioblastoma patients, a simple nutraceutical combination of resveratrol and copper appeared to reduce tumor aggressiveness and key cancer hallmarks without side effects. A new study indicates that glioblastoma becomes less aggressive after treatment with resveratrol and copper, a potentially game-changing finding that could pave the way for a radically new approach to cancer therapy. Treatments such as chemotherapy, radiotherapy and immunotherapy are all designed with a single goal in mind: to destroy cancer. However, what if this long-standing approach is wrong, and...

Certain bitter plant compounds — the kind found naturally in cocoa, apples, berries and red wine — may temporarily boost memory by activating the brain's internal "alarm system," a new study suggests. Researchers at the Shibaura Institute of Technology in Japan found that when mice consumed flavanols — plant-based compounds known for their antioxidant properties — their brains released a surge of noradrenaline, a chemical linked to alertness and focus. Within an hour, the animals performed about 30% better on a memory test compared with untreated mice, according to the findings, which were published in October in the journal Current...

New research suggests that drinking coffee may actually help protect against atrial fibrillation (AFib), a common heart rhythm disorder that causes the heart to beat too quickly and irregularly, sometimes leading to stroke or heart failure. For years, doctors have advised people with AFib and other heart issues to stay away from caffeine, fearing it could worsen symptoms. But a new study from UC San Francisco and the University of Adelaide has found the opposite: participants who drank one cup of caffeinated coffee a day had a 39% lower risk of developing AFib. Why Coffee May Help the Heart"Coffee increases...

A microbial risk score could help identify people at greater riskKey Takeaways Oral bacteria and fungi may help reshape the pancreatic microbiome and promote carcinogenesis. Earlier research has connected periodontal disease and clinical candidiasis with greater pancreatic cancer risk. Altogether, the study identified a more than threefold increase in cancer risk for every one standard deviation rise in a microbial risk score comprised of 27 bacteria and fungi. More than two dozen bacteria and fungi in the mouth may be linked to pancreatic cancer risk, according to an analysis of two large cohorts. Analysis of oral-wash samples from over 120,000...

Up to 10% of pediatric hematologic malignancies attributed to imaging-related radiation exposureKey Takeaways: One in 10 childhood blood cancers may result from medical imaging-associated radiation exposure. Cancer risk increased with cumulative radiation dose, ranging from 1.41 times higher to 3.59 times higher. Children exposed to at least 30 mGy had 25.6 excess blood cancers per 10,000 by age 21. One of every 10 blood cancers in children may result from radiation exposure associated with medical imaging, according to a large retrospective analysis. The risk of hematologic malignancy increased with cumulative radiation exposure versus none, ranging from 1.41 times higher for...
