Diet & Nutrition

Food and beverages provide the energy and nutrients you need to improve health, manage disease, and reduce the risk of disease. Complete nutrition requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity.

Traditional Inuit Diet: Foods, Nutrition, and Health Effects

Traditional Inuit diets combine nutrient-dense marine and terrestrial country foods that remain important sources of protein, vitamin D, vitamin B12, iron, and other essential nutrients. The transition toward market foods is occurring alongside changes in cardiometabolic health, micronutrient intake, and gut microbiome patterns, while food insecurity, socioeconomic conditions, physical activity, colonial processes, and environmental change complicate the relationship between diet and health.

Why a shorter eating window may not mean better metabolic health

In a nationally representative cross-sectional study of 16,973 Korean adults, researchers identified three distinct eating patterns based on the timing and distribution of daily energy intake. Eating later within a shorter daily window was associated with higher odds of metabolic syndrome, elevated blood pressure, triglycerides, and fasting glucose, while frequent grazing showed a mixed metabolic profile.

Cognitive behavioral therapy for insomnia may slow biological aging in older adults

A new UCLA Health study found that treatment of insomnia using cognitive behavioral therapy slowed the pace of biological aging in older adults.

Stevia tastes sweet, but does your body react as if sugar is coming?

In a randomized, double-blind crossover study, researchers tested stevia alone and with glucose in adults with normal weight, overweight, or type 2 diabetes to assess acute effects on blood glucose, insulin, gut hormones, appetite, and subsequent food intake. Stevia produced no significant changes in the measured glycemic or hormonal responses compared with water and did not significantly modify responses to glucose, while appetite and subsequent energy intake were also generally unchanged.

Helicobacter pylori exposure linked to one in five cases of bowel cancer

Exposure to the stomach microbe Helicobacter pylori may be associated with more than 1 in 5 cases of bowel cancer worldwide, suggests an exploratory risk attribution study, published in the open access journal eGastroenterology.

Teens can now order lunch from almost anywhere. Schools are facing a new dilemma

A national survey of 1,027 US adolescents aged 13 to 17 found that nearly one in four reported using mobile food delivery services during school hours, while almost half used them after school. Fast food and sugar-sweetened beverages were among the most commonly ordered items through delivery apps overall, while students also raised concerns about cost, inequality, safety, and disruption at school.

Working shifts may change more than your sleep schedule

A cross-sectional analysis of 1,814 Japanese workers found that shift work was associated with lower raw seafood intake and shorter sleep patterns in both sexes, while female shift workers also consumed less milk and dairy products. Total energy intake was similar between work groups, but male shift workers were more likely to consider preference and convenience when choosing foods, highlighting potentially important differences in dietary quality and lifestyle rather than calorie intake.

A common drink pattern was linked to less sleep and more fatigue in soldiers

A cross-sectional study of 1,155 active-duty Spanish Army personnel identified three distinct co-consumption profiles based on the frequency of caffeinated beverage, energy drink, and sugar-sweetened beverage use. Compared with the lower-frequency profile, the higher-frequency profile was associated with about 14 minutes less sleep per night, lower sleep efficiency, and greater habitual physical fatigue, although the study cannot establish causality or quantify caffeine or sugar exposure.

Could scorpion venom inspire new treatments for liver disease?

Scorpion venom peptides show promising anti-inflammatory, antiviral, analgesic, and immunomodulatory effects, with experimental evidence suggesting that some candidates could target pathways involved in chronic liver disease and viral hepatitis. The review highlights Kv1.3-blocking peptides and antiviral compounds as potential therapeutic leads, while emphasizing that limited hepatic efficacy data, poor pharmacokinetics, immunogenicity, and manufacturing challenges must be overcome before clinical translation.

Could one amino acid help explain why men tend to live shorter lives?

A UK Biobank cohort and Mendelian randomization study involving 272,475 participants linked higher circulating tyrosine with greater all-cause mortality and genetically predicted higher tyrosine with shorter lifespan. After accounting for phenylalanine, the relationship with shorter lifespan was clearest in men, while findings in women were less consistent, suggesting a potential sex-specific role for tyrosine in longevity.

What mothers eat in pregnancy may shape a child’s weight years later

A prospective study of 252 mother-child pairs found that higher combined maternal fruit and vegetable intake during pregnancy was associated with lower odds of overweight or obesity in children at age four. Total and natural fruit juice showed no association, whereas higher commercial fruit juice intake was associated with increased odds, though the authors emphasized that this finding was exploratory.

What four pregnancy eating patterns revealed about mothers and newborns

Researchers analyzing 1,404 pregnant women in Germany identified four distinct dietary patterns that differed substantially in maternal BMI, socioeconomic status, age, and gestational weight gain. A vegetable-rich pattern was also associated with selected neonatal measures, including greater birth length, but most newborn associations were modest or nonsignificant, and the observational study cannot establish causality.

Dual-drug microneedle patch targets inflammation and fat browning

The worldwide obesity crisis has become a dominant public health crisis across the globe. Over 3 billion people worldwide currently suffer from obesity, and forecasts warn the number will rise above 4 billion by 2035, accounting for more than half the global population.

What your gut microbes may have to do with how your brain ages

This review examines how diet-driven changes in the gut microbiota and microbial metabolites may influence cognitive aging through immune, metabolic, neural, endocrine, and barrier-related pathways. It highlights SCFAs, tryptophan-derived metabolites, and bile acids as key signaling mediators while emphasizing that much of the mechanistic evidence remains preclinical and human evidence is largely associative.

What 107 professional MMA fighters actually ate before and after weigh-in

Professional UFC fighters followed highly structured dietary patterns around competition, sharply restricting carbohydrates, fiber, fluids, and sodium before weigh-in before rapidly increasing carbohydrate, fluid, and sodium intake afterward. Despite aggressive post-weigh-in refueling, carbohydrate intake fell again on fight day, suggesting that some fighters may not fully restore glycogen stores before competition.

The obesity-microbiome story is more complicated than ‘good’ and ‘bad’ bacteria

This review finds that obesity is linked to reciprocal interactions between diet, the gut microbiome, microbial metabolites, and host metabolic pathways that influence appetite, insulin sensitivity, inflammation, and energy balance across the lifespan. It highlights diet as a particularly tractable way to influence this system, while emphasizing that microbiome changes associated with GLP-1 therapies remain difficult to separate from weight loss and that functional multi-omics approaches may help enable more personalized interventions.

Coffee, tea and dementia risk: Why the amount you drink could matter

A targeted perspective synthesizes epidemiological and mechanistic evidence examining how caffeine consumption during midlife may influence dementia risk later in life. The authors highlight potential roles for dose, age, CYP1A2 genotype, adenosine signaling and cultural drinking practices, while stressing that current observational evidence cannot establish causality.
