High-Fiber Diet Outperformed Metformin in a Small Trial—but Don’t Replace Medication
A small randomized trial found better short-term HbA1c and BMI results with a prescribed high-fiber intervention than metformin alone, but important design limits prevent treatment conclusions.
Late-Night Eating Was Linked to Fatty Liver Disease—Not Proven to Cause It
A large observational analysis links habitual late-night eating with higher relative rates of fatty liver disease and cirrhosis, but it cannot establish cause and effect.
Peanuts Changed a Brain Insulin Signal—but Did Not Prove Dementia Protection
A small randomized crossover trial found a regional brain blood-flow response to insulin after 16 weeks of daily peanuts, but it did not establish dementia prevention or clinical…
Olive Oil Before Carbohydrates Slowed an Early Glucose Spike—in Mice
A new mouse study found that giving fat before glucose delayed gastric emptying and softened the early blood-sugar rise, but it does not establish a human treatment.
Potassium-Rich DASH Diet Appeared Safe With Common Blood-Pressure Medicines
A preliminary analysis of 356 adults found no dangerous potassium increase after three months of DASH-patterned groceries, but the result is not yet peer reviewed.
Nutrient-Dense Meals Lowered LDL—but Missed the Trial’s Main Outcomes
A 300-person randomized trial found no advantage on its primary endpoints, while LDL, blood-pressure and microbiome findings remained exploratory.
Nutrient-Matched Ultraprocessed Meal Triggered a Larger Insulin Response
A randomized crossover study found different short-term insulin, energy-use and brain responses after nutrient-matched ultraprocessed and non-ultraprocessed meals.
Walnuts and visceral fat: what a 12-week randomized trial found
A 12-week randomized trial found faster changes in abdominal-fat measures with a walnut-based lower-carbohydrate diet, but no significant between-group differences at the endpoint.
High-polyphenol olive oil: what the small HEVOOC trial actually shows
A small randomized crossover trial confirms greater phenolic exposure, while metabolic benefits remain exploratory.
Mediterranean diet and the microbiome: a randomized trial found no clear shift
A 24-week randomized trial found no clear group-level microbiome or stool-metabolite change after a Mediterranean-diet intervention.
Sugar, antibiotics, and the microbiome: what a new Nature study found
A new human cohort study, supported by mouse experiments, links sugar-rich eating during antibiotics with deeper gut-microbiome disruption.
Can early type 2 diabetes enter remission? What the RESET trial found
A randomized trial found 54% remission after an intensive supervised diet-and-exercise program, versus 4% with usual care.
