Researchers found that combining regular exercise with omega-3 supplements can make a big difference for oral health. The duo helps the immune system fight off chronic tooth root infections and reduces bone loss around the teeth. In animal studies, those that both exercised and took omega-3s had much lower inflammation and healthier bone structure.

A new study shows that eating more fruits and vegetables during the day can significantly improve sleep that same night. Researchers found a clear link between diet quality and sleep depth, with participants who met the CDC’s daily produce recommendations seeing a 16% boost in sleep quality. The findings suggest that small dietary changes could […]

Scientists have identified mutations in the CPD gene as a key cause of a rare congenital hearing loss, revealing how disruptions in arginine and nitric oxide signaling damage sensory cells in the ear. Using mouse and fruit fly models, the team showed that restoring arginine levels or using sildenafil improved cell survival and hearing function.

ASU scientists found that people whose gut microbes make more methane extract more calories from fiber-rich foods. Methanogens help the microbiome turn fiber into energy by consuming hydrogen and producing methane. Using advanced metabolic chambers, researchers measured how diet and gut chemistry interact, showing that methane may signal efficient digestion. The work could lead to […]

MIT scientists have found that an amino acid called cysteine can help the gut heal itself. In mouse studies, a cysteine-rich diet activated immune cells that release a molecule speeding up tissue repair in the small intestine. This process helped regenerate the gut lining after damage from radiation or chemotherapy.

McMaster researchers found that deep abdominal and liver fat can quietly damage arteries, even in people who appear fit. Their MRI-based study of over 33,000 adults shows these fats are closely linked to artery thickening and stroke risk, regardless of cholesterol or blood pressure. The findings challenge BMI as a reliable indicator of health and […]

Researchers at King’s College London have created the first evidence-based dietary guidelines for chronic constipation, finding real relief may come from kiwifruit, rye bread, and mineral water. Psyllium, probiotics, and magnesium oxide also showed benefits, while common fiber and senna advice fell short. The guidelines emphasize self-management and high-quality evidence, offering practical tools for patients […]

A study found that daily vitamin D supplements helped slow telomere shortening—the cellular process linked to aging and disease. Researchers believe its anti-inflammatory effects may protect DNA. While results are promising, the ideal dose remains unclear, and experts stress that lifestyle choices still matter most for longevity.

New research reveals that exercise counteracts the mood-damaging effects of a Western-style diet through specific gut and hormonal mechanisms. Running restored metabolites tied to mental well-being and balanced key hormones like insulin and leptin. However, poor diet limited the brain’s ability to generate new neurons, showing diet still matters for full brain benefits.

Mizzou scientists are exploring how a ketogenic diet may protect the brain and prevent Alzheimer’s in people genetically predisposed to it. Their study found that female mice with the APOE4 gene benefited most, showing improved gut and brain health on a high-fat, low-carb diet. The findings highlight the value of personalized nutrition and early intervention […]
