Eating sugary foods more than twice a week was linked to 28% higher breast cancer risk

In a prospective study of 71,264 Korean women followed for an average of 9.2 years, researchers identified 713 breast cancer cases and examined how different dietary sugar sources related to cancer risk. Women consuming high-sugar foods more than twice weekly had a 28% higher breast cancer risk than those consuming them no more than once a month, while total sugar intake and fruit consumption showed no significant association.

Beer and liquor show more oral bacteria links than wine in a large US study

Researchers analyzed beverage intake and oral microbiome data from 5,598 adults across three US cohorts and found that alcohol consumption showed the strongest associations with oral bacterial diversity and composition among the beverages examined. Higher alcohol intake was associated with greater bacterial richness and differences in genera linked to oral health, but the cross-sectional preprint could not establish whether alcohol caused these differences or influenced disease risk.

Regular tea consumption linked to lower risk of vascular disease

In a Journal of Internal Medicine study, people who drank tea had a lower risk of vascular disease than non–tea drinkers.

Rice, fish and pickles: Is the traditional Japanese diet as healthy as we think?

A systematic review of 37 studies found that greater adherence to predefined Japanese-style dietary patterns was associated with lower all-cause and cardiovascular mortality, based on pooled evidence from three cohort studies. However, health associations varied according to dietary composition, suggesting that traditional Japanese diet scores alone may not adequately distinguish the potential benefits and risks of different food combinations.

Yoghurt, coffee and chocolate have something in common, and researchers mapped it across Europe

Researchers surveyed 12,646 adults across 53 European countries and found that fermented dairy products were widely consumed, while other fermented foods showed considerable regional differences in popularity and intake. The findings revealed that high consumer prevalence did not necessarily translate into substantial consumption, highlighting the importance of measuring both how many people eat fermented foods and the quantities they consume.

Your diet may have more to do with your sense of smell than you think

Researchers analyzed dietary patterns and odor identification in 6,690 adults in Italy, finding that healthier plant-rich diets, particularly those emphasizing fruits and vegetables, were associated with better olfactory function and lower odds of hyposmia. Diets emphasizing less healthy plant foods showed the opposite association, although the cross-sectional study could not establish whether diet influences smell or impaired smell affects food choices.

AI-powered home monitoring tracks older adults’ health while protecting privacy

Older people could be monitored safely in their own homes without the need for intrusive cameras or wearable devices thanks to new research by Nottingham Trent University (NTU).

Cranberry juice doesn’t affect every woman the same way

Cranberry juice's effectiveness against UTIs varies among women due to metabolic differences, impacting urinary anti-adhesion activity and pathogen response.

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.

Several cups of coffee a day showed no clear diabetes link over 10 years

Researchers followed 1,158 adults in Italy for 10 years, comparing those who drank at least two to three cups of coffee daily with those who drank none. They found no statistically significant difference in new cases of impaired fasting glucose or type 2 diabetes, but the small non-consumer group limits how confidently the study can rule out a difference in risk.

Could a daily glass of orange juice support heart health? Study finds citrus compounds influence genes linked to blood vessel function

Naturally occurring compounds in orange juice regulated genes involved in the control of cardiovascular and blood vessel function, according to a new clinical trial.

Like your tea or coffee very hot? A study of nearly 1 million adults found a striking cancer link

In pooled prospective data from 977,282 UK adults, preferring tea or coffee “very hot” was associated with more than threefold higher risk of esophageal squamous cell carcinoma compared with preferring drinks “warm,” while drink temperature showed no material association with adenocarcinoma risk. Consuming six or more hot drinks daily was independently associated with higher squamous cell carcinoma risk, and modeling estimated that about 440 UK cases each year could be prevented by switching from “very hot” to “hot” drinks if the association is causal.

Coffee after colorectal cancer? Decaf and caffeine show different links with mortality

In a prospective analysis of 1,098 people with colorectal cancer, researchers found no significant association between total or caffeinated coffee intake and all-cause or colorectal cancer-specific mortality in the cohort overall. Decaffeinated coffee was associated with lower all-cause mortality, while the highest quartile of caffeine intake was associated with lower all-cause and colorectal cancer-specific mortality, although the observational study cannot establish causation.

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.

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.

Coffee’s link to Parkinson’s risk may depend on how your body handles caffeine

In 435,551 UK Biobank participants followed for a median of 15.7 years, overall coffee consumption was not associated with Parkinson’s disease risk, but the relationship differed significantly according to CYP1A2 genotype. Lower risk was observed with low-to-moderate coffee intake among fast-metabolizer AA carriers, while higher intake was associated with increased risk among AC and CC carriers, although the observational findings do not establish causality and sex-specific patterns require cautious interpretation.

Tea, berries and dark chocolate featured in a diet linked to lower Parkinson’s risk

A prospective UK Biobank study of 123,655 adults found that a dietary pattern richer in flavonoid-containing foods was modestly associated with a lower incidence of hospital-recorded Parkinson’s disease. The association was strongest among those with the highest flavonoid diet scores, while exploratory proteomic and transcriptomic analyses pointed to possible neuroimmune and cell-adhesion pathways but did not establish causality or mechanism.
