TL;DR: A 2026 longitudinal study in Appetite following 491 Quebec children found that infants breastfed for at least three to six months showed better inhibitory control — the ability to suppress an automatic response — at age three and a half than infants who were never breastfed, with the largest behavioral benefits in those breastfed …
How Five-Animal Play Matched Probiotics in Prediabetes TL;DR: 4 weeks of Huatuo Five-Animal Play improved glucose control and insulin resistance about as much as bifidobacterium capsules, outperforming low-intensity cycling on several metabolic markers, including Wnt5a. Key Findings Exercise shifted glucose and GLP-1: Researchers randomized 90 people with impaired glucose tolerance to bifidobacterium triple viable capsules, …
Meat Intake Linked to Lower Dementia Risk in APOE4 Carriers TL;DR: In APOE4 carriers, higher total meat intake tracked with lower observed dementia risk over 15 years, while a higher processed-to-total meat ratio moved in the unfavorable direction. Key Findings 2,157 dementia-free adults: The study used the Swedish National Study on Aging and Care-Kungsholmen cohort …
FGF21 Hindbrain Neurons Controlled Protein Hunger TL;DR: During protein restriction, liver-derived FGF21 acted through glutamatergic beta-klotho neurons in the nucleus of the solitary tract to change food intake, food choice, and energy expenditure in mice. Key Findings NTS-KLB neurons responded directly: Klb-expressing glutamatergic neurons in the nucleus of the solitary tract were activated by FGF21. …
EPA Rewired Brain Vessels After Repetitive Brain Injury TL;DR: Fish-oil-derived EPA looked less like a simple neuroprotective supplement and more like a lipid signal that changed brain-vessel repair after repetitive mild traumatic brain injury. Key Findings EPA accumulated before injury: In a fish-oil diet model, eicosapentaenoic acid built up in the brain at baseline rather …
Mediterranean Diet Linked Mitochondrial Microproteins TL;DR: Mediterranean diet adherence tracked with higher mitochondrial microproteins Humanin and SHMOOSE in older adults, pointing to a possible mitochondrial route for healthy-aging benefits. Key Findings Higher adherence tracked with SHMOOSE: Patients with stronger Mediterranean diet adherence showed higher circulating SHMOOSE levels. Humanin moved with diet and Nox2: Humanin was …
Caffeinated Coffee Linked to Lower Dementia Risk Over 43 Years TL;DR: Caffeinated coffee drinkers had 141 vs 330 dementia cases per 100,000 person-years in the highest versus lowest intake quartiles — across 131,821 adults followed up to 43 years. Decaf showed no comparable signal. Key Findings Caffeinated coffee: 141 vs 330 dementia cases per 100,000 …
Krill Oil vs Fish Oil: Which Omega-3 Source Wins Against Inflammation and Oxidative Stress? TL;DR: Krill oil has a slight edge for inflammation due to astaxanthin, but fish oil wins for raising blood omega-3 levels and long-term cardiovascular outcomes. Fish oil has dominated the omega-3 supplement market for decades. But a smaller crustacean from Antarctic …
Fish Oil Supplements Aren’t the Villain TL;DR: A comprehensive review of the UK Biobank found that fish oil supplements show favorable associations with health outcomes—not harmful ones—contradicting recent alarming headlines about atrial fibrillation risk. When a major study claims fish oil supplements increase heart arrhythmia risk, the headlines scream. But what happens when researchers dig …
Obesity and Depression Share Five Converging Biological Pathways Obesity and depression represent two of the world’s fastest-growing epidemics. By 2030, over 1 billion people will have obesity, while depression will affect more than 350 million. Yet they are rarely treated together despite overwhelming evidence they are mechanistically linked. Epidemiological data reveal a striking bidirectional relationship: …
