A small randomized trial in older adults found that four weeks of dietary changes improved some biomarkers tied to biological age, but that does not mean aging itself was reversed.
A new JAMA perspective argues that while GLP-1 drugs can dramatically reduce appetite and body weight, exercise may still play a critical role in preserving muscle, supporting metabolic health and helping people maintain results long term.
A large MRI study found that fat stored inside muscle was linked to higher odds of blood pressure, blood sugar and cholesterol problems, even in adults without known disease.
A large observational study of older adults found that people who ate eggs more often were less likely to be diagnosed with Alzheimer’s disease over time, though researchers cannot say eggs themselves were the cause.
A 24-year study found that higher long-term BMI was associated with steeper cognitive decline in older adults, but BMI is only one piece of a much bigger brain health puzzle.
A small meta-analysis of randomized trials suggests plant-based eating patterns may reduce C-reactive protein, a marker linked to inflammation, though the findings do not prove that simply cutting animal products guarantees better health.
A meta-analysis of randomized trials suggests structured pre-surgery programs may help reduce complications and shorten hospital stays, though results likely depend on the type of surgery and support provided.
Higher isoflavone intake was associated with fewer symptoms in a new study.
A global analysis finds that a few common gaps in everyday eating patterns account for millions of heart-related deaths each year.
A large Nordic study finds timing matters for women taking antiseizure medications, with no benefit seen when supplements begin after pregnancy starts.
A new study links the “neuroactive potential” of gut bacteria to cognition and depression in older adults, though the findings are observational and do not show cause and effect.
A study of older adults found higher ultraprocessed food consumption was associated with more fat stored inside thigh muscles, though the research does not show cause and effect.
Timing may matter as much as total weight, with earlier gains tied to longer exposure and greater risk.
Not all plant-based diets are created equal, with whole foods linked to lower risk and refined options tied to higher risk.
A short-term study found reduced greenhouse gas emissions among participants following a structured vegan diet, though results reflect a specific intervention and population.
Research in older adults found that adding salt at the table varies by gender and lifestyle, highlighting a behavior that may contribute to overall sodium intake.
A long-term study found an association with tau protein, though not all markers of Alzheimer’s disease were affected.
A large U.S. study suggests drinking patterns, not just total alcohol intake, may influence liver health risk.
A global modeling study finds that adding vitamins and minerals to staple foods like salt and flour already reduces nutrient shortfalls at scale, with potential to expand impact at low cost.
Long-term data suggest a Mediterranean-style eating pattern may be tied to slower loss of brain volume, though researchers caution it’s not cause and effect
New data shows adolescent obesity has increased over the past decade, while weight-loss efforts have declined, raising questions about motivation, mental health, and changing norms
A mouse study suggests heavy alcohol use in early adulthood, especially alongside stress, could affect cognitive flexibility later in life—even after years of not drinking
A new study suggests fermentation and bean selection can shift both flavor and nutrient content, but more antioxidants don’t necessarily mean a healthier chocolate
Researchers say aeroponic farming techniques could help deliver vitamin B12 through plant foods, potentially offering a new option for people who eat little or no animal products.
Researchers comparing AI-generated diet plans with those created by a registered dietitian found the AI versions underestimated calorie needs and skewed macronutrient balance for adolescents trying to lose weight.
