Can camel milk improve health? Review highlights benefits but warns against drinking it raw

A narrative review in Food Science & Nutrition examined studies published from 2000 to 2025 and found that camel milk contains bioactive compounds with potential glycemic, anti-inflammatory, gut, and other health benefits. It also stressed that raw, unpasteurized camel milk poses microbial and zoonotic risks, underscoring that safety remains a key part of the story.

Nepal and Afghanistan show how abrupt aid cuts can unravel essential care

Abrupt cuts to external health aid can destabilize multiple essential services simultaneously in fragile, donor-dependent settings, as illustrated by Nepal and Afghanistan. The paper argues that donor withdrawal is not just a resilience test, but also an ethical and governance issue that should be managed through “transition discipline.”

Moderate coffee intake may lower heart failure risk

A systematic review and dose-response meta-analysis of seven prospective cohorts found that drinking 2 to 4 cups of coffee a day was associated with a modestly lower risk of incident heart failure. The lowest estimated risk appeared at 1 to 2 cups daily, although the evidence for a true non-linear J-shaped pattern was suggestive rather than definitive.

Wholegrain rye changes gut bacteria and lowers inflammation in obesity trial

In a 12-week randomized trial, replacing refined wheat with wholegrain rye in a calorie-restricted diet did not produce greater weight loss in adults with overweight or obesity. Wholegrain rye did, however, lower C-reactive protein and alter gut microbiota and short-chain fatty acids in ways that may have positive cardiometabolic implications.

Mediterranean diet may protect health through mitochondrial microproteins

A new study led by researchers at the USC Leonard Davis School of Gerontology suggests that the benefits of the Mediterranean diet may be driven, in part, by tiny proteins hidden within our mitochondria, opening a new window into how diet shapes aging and disease risk.

Leaving home may worsen diet quality in young adults, Australian study finds

Australian longitudinal data suggest that leaving the parental home is associated with a small decline in overall diet quality and a short-term rise in discretionary food intake during the transition from adolescence to adulthood. The study also found that diet quality tended to worsen most among those moving in with a partner, while the discretionary-food gap narrowed over time.

Lab-grown food pipe offers hope for children with esophageal conditions

Scientists from Great Ormond Street Hospital (GOSH) and University College London (UCL) have created the first lab‑grown esophagus - the food pipe - shown to safely replace a full section of the organ and restore normal function, including swallowing, in a growing animal without the need for immunosuppression.

Early adulthood hypertension linked to heart and kidney disease later in life

Higher blood pressure during young adulthood is likely linked to a higher risk of heart disease and kidney disease later in life, reinforcing the importance of maintaining healthy blood pressure at younger ages, according to preliminary research presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026.

Replacing sedentary time improves insulin resistance in adolescents

Adolescents who replaced just half an hour of sedentary behaviors, such as sitting on the couch or spending time at the computer, each day for moderate-to-vigorous physical activity or sleep may lower their insulin resistance, a key factor in preventing the development of Type 2 diabetes, according to preliminary research presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026.

Higher meat intake may slow cognitive decline in older adults with APOE ε4

In older Swedish adults, higher meat intake was associated with slower cognitive decline and lower dementia risk among people carrying APOE ε3/ε4 or ε4/ε4, but not among other genotype groups. A higher processed-to-total meat ratio was linked to worse dementia outcomes, while unprocessed red meat and poultry showed no substantial difference.

U.S. study links ultra-processed foods to lower odds of fertility

A cross-sectional NHANES study of 2,582 U.S. women found that higher ultra-processed food intake was associated with lower odds of being classified as fertile based on self-reported infertility history. Greater Mediterranean diet adherence was linked to higher odds of fertility in adjusted models, but that association was no longer significant after accounting for obesity.
