A 20-year study of 90,000 adults suggests the type of fish you eat matters

A Japanese study following 90,944 adults for an average of 20.8 years found that associations between seafood consumption and mortality varied by fish type and sex. Moderate seafood consumption was linked to lower overall mortality among women, while higher intake of omega-3-rich fish in women and unsalted seafood in men was associated with lower cerebrovascular disease mortality.

Not all ultra-processed foods show the same cancer risk

Ultra-processed foods show varied associations with colorectal cancer, underscoring the need for precise research on diet quality and cancer risk factors.

Could eating whey protein before meals help reduce blood sugar spikes?

A narrative review of 57 randomized trials found that milk and dairy products have inconsistent effects on long-term blood sugar control in adults with type 2 diabetes or prediabetes. Whey protein consumed before meals more consistently reduced short-term blood sugar spikes, but further research is needed to establish whether these benefits persist over time.

Australians trust dietary advice. But few know how much fat is recommended

Australian adults show low awareness and adherence to national dietary fat guidelines.

Overall dietary patterns matter more for heart health than nutrients

A healthy, balanced dietary pattern, rather than one focused on individual nutrients or foods is key to maintaining heart health, according to a Scientific Statement issued by the American College of Cardiology and published in JACC, its flagship journal.

Shatavari may affect more than hormones, and the gut could help explain why

A review in Nutrients examined how bioactive compounds in Asparagus racemosus (Shatavari) may influence cognitive health through the microbiota-gut-brain axis, estrogen-related signaling, neuroinflammation, oxidative stress, and neurotransmitter regulation. Evidence from computational, cellular, animal, and limited human studies suggests several plausible biological pathways, but key questions remain about bioavailability, brain exposure, dosing, and clinical efficacy.

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.

Plant-based fats improve long-term survival for prostate cancer patients

Men diagnosed with nonmetastatic prostate cancer can generally expect to live for many years after their diagnosis. However, cardiovascular disease and other cancers remain important threats to their long-term health.

The diet-Alzheimer’s connection is more complicated than “eat this, avoid that”

A mini-review finds that dietary patterns may influence Alzheimer’s disease through interconnected pathways involving neuroinflammation, insulin resistance, oxidative stress, blood-brain barrier dysfunction, homocysteine, and the gut-brain axis. The authors argue that genetics, sex, age, physical activity, and socioeconomic context may modify these relationships, supporting more individualized approaches to nutrition research and dementia prevention.

Gut microbiome shifts may begin before Alzheimer’s symptoms appear

A narrative review links reduced SCFA-producing gut bacteria and altered microbial metabolism with Alzheimer’s disease, while early evidence suggests similar changes may appear before cognitive symptoms. Mediterranean, DASH, MIND, and prudent diets are associated with beneficial microbial profiles, but direct evidence connecting diet, the microbiome, and amyloid pathology remains limited.

Planetary Health Diet lowers cardiovascular risk in older women

A 20-year study of more than 65,000 postmenopausal women found that higher adherence to the Planetary Health Diet was associated with a lower risk of overall cardiovascular disease, coronary heart disease, stroke and heart failure.

Maternal diets high in UPFs may influence children’s health years later

A narrative review of 84 publications links higher ultra-processed food intake during pregnancy and early childhood with poorer diet quality, maternal complications, childhood obesity, and potential immune, metabolic, and neurodevelopmental effects. The authors identify possible microbiome and biopsychosocial pathways but emphasize that the predominantly observational evidence cannot establish causality.

Fear of new foods may affect more than dietary variety

Higher food neophobia was associated with poorer self-reported physical and mental health among 4,537 adults in Australia, the United Kingdom, and the United States. The relationship remained after accounting for age, gender, education, and country, although the cross-sectional study could not establish causation.

Comprehensive food regulations lower obesity risk among children

Chile's complementary set of policies targeting food products high in fat, salt and sugar plausibly reduces the risk of school age children being overweight or having obesity, finds a study published in The Lancet.

Western diet weakens the gut’s nervous system through iron-dependent damage

A JCI study found that exposure to a Western diet in mice and to palmitic acid in murine and ex vivo human enteric nervous system models triggered ferroptosis, characterized by iron loading, lipid peroxidation, mitochondrial stress, and enteric neuronal loss. Boosting Nrf2 signaling protected enteric neurons and prevented Western diet-induced delayed colonic transit in mice, pointing to a potential pathway linking dietary fat exposure to gut motility dysfunction.

Chia seeds may boost fetal brain DHA during obesity-linked pregnancy

Chia seed supplementation during pregnancy increased maternal omega-3 long-chain fatty acids, including DHA, in a rat model of high-fat-high-sugar diet-induced obesity. The findings suggest plant-derived ALA from chia seeds may improve maternal, placental, and mid-gestation fetal brain lipid profiles, but human relevance and offspring outcomes still need testing.

Urges for cardiologists to screen patients for UPF intake

The European Society of Cardiology identifies ultra-processed foods as a key cardiovascular risk, urging a shift in dietary guidelines for better heart health.

Blue Zones longevity claims may rest on flawed records, essay argues

Essay challenges the scientific validity of the Blue Zones concept and Ancel Keys’ Lipid Hypothesis, arguing that both rest on biased data, weak records, and methodological flaws. The authors say some longevity claims may reflect clerical errors, poverty, and unreliable vital records rather than uniquely healthy lifestyles.

Scientists will probe whether processing itself makes ultra-processed foods harmful

A randomized controlled trial protocol will test whether the cardiometabolic risks linked to ultra-processed foods stem from industrial processing, poor nutrient composition, or both. Using four controlled diets, researchers will separate the effects of UPF content from saturated fat, added sugar, and sodium on LDL cholesterol, insulin resistance, and blood pressure.
