Can a Month of Diet Changes Really Make You ‘Biologically Younger?’

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.

Eating More Beans, Soy Linked to Lower High Blood Pressure Risk

A major review of long-term studies found people who ate more legumes and soy foods were less likely to develop high blood pressure, though the research cannot prove these foods alone were responsible.

Higher Egg Intake Linked to Lower Alzheimer’s Risk in Long-Term Study

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.

Weight Gain Earlier in Adulthood Linked to Higher Risk of Early Death

Timing may matter as much as total weight, with earlier gains tied to longer exposure and greater risk.

Plant-Based Diet Quality Linked to Dementia Risk, Large Study Finds

Not all plant-based diets are created equal, with whole foods linked to lower risk and refined options tied to higher risk.

Why Diabetes Risk Isn’t the Same for Everyone

A new study finds that different metabolic patterns may predict who develops diabetes and related complications, even before diagnosis

Small Daily Changes May Add Up to Big Heart Health Benefits

A new study finds that modest improvements in sleep, diet, and activity together are linked to a lower risk of heart attack and stroke

Can What You Eat Slow Brain Aging? Study Links MIND Diet to Less Brain Shrinkage

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

Scientists Grow Vitamin B12–Fortified Pea Shoots in New Indoor Farming Study

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.

Vitamin D Didn’t Reduce COVID Severity in Large Trial, but Researchers Saw Possible Link to Lower Long COVID Risk

A randomized clinical trial found high-dose vitamin D supplements did not reduce COVID hospitalizations or symptom severity, though researchers observed a small signal suggesting fewer long COVID symptoms among participants who took the vitamin.

Higher Ultraprocessed Food Intake Linked to Lower Bone Density and Higher Hip Fracture Risk

A large study of more than 160,000 adults found that people who ate more ultraprocessed foods tended to have lower bone mineral density and a modestly higher risk of hip fractures.

Can Gut Bacteria Reach the Brain? A Mouse Study Suggests Diet May Play a Role

Researchers found that changes in the gut microbiome linked to a high-fat diet allowed small numbers of bacteria to travel to the brain in mice, pointing to a possible new pathway connecting diet and neurological health.

Keto Diet Improved Exercise Response in Mice With High Blood Sugar

A study in hyperglycemic mice suggests a ketogenic diet restored aerobic adaptation to exercise, raising questions about how blood sugar may blunt training benefits.

Parental Weight Before Pregnancy Linked to Higher MASLD Risk

A UK birth cohort study suggests both maternal and paternal BMI before conception may shape a child’s long-term liver health, with childhood weight playing a major role.

Healthy Diet Patterns Linked to Lower Risk of Early Cognitive Decline

A large study found the strongest associations when people ate well in midlife, not just later on.

Binge Drinking Linked to Higher Mortality Risk in Adults 50 and Older

A large Canadian study finds frequent binge drinking is associated with increased risk of death later in life, even after accounting for health and lifestyle factors.

Cutting Back on Meat Did Not Lead to Nutrient Deficiencies

A long-running Swedish cohort study suggests a climate-friendly, plant-forward diet can support nutrient adequacy and may be linked to lower cardiometabolic risk.

Low-Carb, Low-Fat Diets Lower Heart Risk When Food Quality Is High

Large cohort analysis suggests plant-based, minimally refined foods matter more than macronutrient ratios for coronary disease risk.

A 'Hidden' Group of Gut Bacteria Is Consistently Linked to Better Health

A global analysis suggests that little-studied microbes may help keep the gut ecosystem running smoothly across diets and cultures.

Higher Ultraprocessed Food Intake Linked to Mortality Risk Among Cancer Survivors

A long-term Italian study finds cancer survivors who ate more ultraprocessed foods had higher death rates, even after accounting for overall diet quality.

Researchers Push Back on Claims That Blue Zones Longevity Data Are Flawed

A new peer-reviewed analysis finds that age records from the world’s longest-lived regions meet rigorous scientific standards, reinforcing their value for aging and nutrition research.

Heart-Healthy Eating Linked to Longer Survival After Cancer

An Italian study suggests cancer survivors who follow healthier eating patterns and other heart-protective habits may live longer than those who do not.

Cutting Saturated Fat Linked to Lower Death Risk Only in High-Risk Groups

A large analysis suggests benefits depend on cardiovascular risk and what replaces saturated fat, not simply reducing it.

Dark Chocolate Compound Linked to Signs of Slower Biological Aging

A large human study finds that higher blood levels of theobromine, a compound from cocoa, are associated with younger biological age.

Early Humans Ate More Processed Plants Than Paleo Myths Suggest

New archaeological research shows our ancestors ground, cooked and transformed plant foods long before farming began.
