Women face higher depression risk from unhealthy food

A cross-sectional study of over 15,000 adults across multiple countries found that ultra-processed food (UPF) consumption was linked to higher odds of depression, especially in women across all age groups. Healthy dietary patterns were protective in women aged 18–54, but showed no benefit for men.

TM6SF2 gut-specific knockout aggravates liver lipid accumulation in MASLD mice

Metabolic dysfunction-associated steatotic liver disease (MASLD), is the most common form of chronic liver disease worldwide. This study aimed to explore the role of TM6SF2 in high-fat diet (HFD)-induced MASLD through the gut-liver axis.

Can your diet affect fertility? Gut-linked dietary score reveals surprising risk pattern

A cross-sectional study of over 3,000 U.S. women found a non-linear link between a gut microbiota-based dietary index (DI-GM) and infertility. Risk decreased with healthier diets but unexpectedly rose beyond a certain threshold score.

Black coffee improves insulin sensitivity in women, study finds

Two daily cups of coffee, especially black, are linked to lower insulin resistance and fasting insulin levels in Korean women, suggesting coffee may improve glucose metabolism. The effect was not observed with coffee containing sugar or cream.

Phthalates in plastics linked to over 350,000 heart deaths worldwide

A global modeling study in eBioMedicine links phthalate exposure from plastics, especially DEHP metabolites, to over 356,000 cardiovascular deaths in 2018. Exposure was highest in Asia, the Middle East, and Africa, disproportionately affecting lower-income countries.

Are one-year-olds in Australia eating right? New study reveals nutrient gaps

A study from the ORIGINS cohort in Western Australia assessed the diets of one-year-old children, comparing intake to national guidelines. While most nutrient targets were met, key shortfalls in iodine and excessive sodium intake raised concerns, especially for breastfed infants.

HO-1 regulates liver fibrosis in NAFLD through the SIRT1 TGF-β Smad3 pathway

Heme oxygenase 1 (HO-1) has an influential yet insufficiently investigated effect on Sirtuin 1 (SIRT1), a histone deacetylase activated by nicotinamide adenine dinucleotide, which may impact the transforming growth factor-β (TGF-ß)/Smad3 pathway in nonalcoholic fatty liver disease (NAFLD)-related liver fibrosis.

Researchers tie childhood vitamin D shortfalls to adult heart disease

Low childhood levels of 25-hydroxyvitamin D were linked to a significantly higher risk of early adult-onset atherosclerotic cardiovascular disease (ASCVD). The association remained even after accounting for conventional childhood risk factors and persisted across multiple analyses.

What’s missing in plant-based nutrition research? A new review explains

A new scoping review reveals major inconsistencies in how plant-based diet diversity is defined, measured, and linked to health outcomes in high-income countries. The findings highlight a critical need for standard definitions and validated assessment tools in future research.

Extreme temperatures drive people toward high-fat diets, study finds

Short-term exposure to extreme temperatures alters dietary patterns by increasing fat intake, even when total calorie consumption remains stable. This shift, driven by physiological appetite regulation, raises the risk of high-fat diets and diet-related diseases, especially among vulnerable groups.

Higher biological age linked to increased dementia risk

People whose biological age is higher than their chronological age may be more likely to develop dementia than people whose biological age matches or is lower than their chronological age, according to a study published on April 30, 2025, online in Neurology, the medical journal of the American Academy of Neurology.

Better sleep, BMI, and glucose control lower female infertility odds

A new study using NHANES data found that higher Life’s Crucial 9 (LC9) scores, reflecting better cardiovascular and mental health, were linked to lower odds of female infertility. However, adding depression to the LE8 framework did not significantly improve its predictive value.

Gut bacteria and metabolites reveal depression-linked patterns in older adults

A cross-sectional study of 400 older adults with metabolic syndrome reveals that individuals with depression have distinct gut microbiota and metabolite profiles. Eight bacterial genera and 15 fecal metabolites were significantly associated with depression, suggesting a gut-brain axis link.
