Dietary restriction boosts antitumour immunity by rewiring T cell metabolism

Dietary restriction reshapes CD8+ T cell metabolism by increasing ketone body–driven acetyl-CoA production, preventing terminal exhaustion and enhancing tumour control in mice. This metabolic reprogramming also boosts responsiveness to PD-1 blockade, suggesting a potential strategy to improve cancer immunotherapy.

Why the form of vitamin B12 you take may matter more than your intake

This comprehensive review examines vitamin B12 absorption, physiological roles, deficiency states, and dietary sources, with particular attention to differences between natural and synthetic forms. The authors conclude that while all B12 forms raise circulating levels, methylcobalamin may offer advantages in specific clinical contexts, especially where absorption or metabolic conversion is impaired.

Anxiety and insomnia linked to reduced natural killer cell levels in young women

Natural killer (NK) cells are the bodyguards of our immune system. As a first line of defense, they destroy invading pathogens, foreign bodies, and infected cells in early stages, thereby preventing them from spreading.

Filtered coffee shows a causal link to healthier HbA1c levels

Genetically predicted filtered coffee consumption is causally associated with lower HbA1c levels, while other coffee preparation methods show no such benefit. This effect appears to be partly mediated by increases in propionate producing gut bacteria, particularly Veillonella.

Home-delivered, medically tailored groceries benefit people with diabetes facing food insecurity

A new study in the Journal of Nutrition Education and Behavior (JNEB), published by Elsevier, evaluated a 12-week home-delivered food and education program among adults in Northwest Arkansas.

National study maps where food additives come from in children’s and adults’ diets

By analysing nationally representative diet data, researchers show that food additives rarely occur alone, with children and teenagers experiencing the highest exposure to complex additive mixtures largely driven by ultra-processed foods.

Sterilized fermented beverage targets obesity and type 2 diabetes pathways in computational study

Researchers profiled a terminally sterilized probiotic-fermented MFH beverage and identified aporphine alkaloids and flavonoids with favorable predicted ADMET properties. Integrated network pharmacology, molecular docking, and 100-ns MD simulations suggest multi-target engagement of metabolic-inflammatory pathways relevant to obesity and type 2 diabetes.

Researchers discover new biomarker of "complicated" mild- to severe-pediatric traumatic brain injury

Researchers at the University of Pittsburgh and UPMC Children's Hospital of Pittsburgh discovered a promising new biomarker of "complicated" mild- to severe-pediatric traumatic brain injury, or TBI.

Gut microbe metabolite TMA improves blood sugar by shutting down a key inflammatory switch

Researchers identified trimethylamine (TMA) as a gut microbe–derived metabolite that directly inhibits IRAK4 to reduce metabolic inflammation and improve glycaemic control in high-fat-diet-fed mice. Choline-driven increases in TMA production replicated these benefits, revealing a host–microbe signaling axis with therapeutic potential for obesity-associated insulin resistance.

Dietary restriction reprograms cancer-fighting immune cells to enhance anti-tumour immunity

Reducing calorie intake helps cancer-fighting immune cells do their jobs more effectively, reports a study by Van Andel Institute scientists and collaborators.

Routine blood test may flag hidden osteoporosis risk, study finds

A large hospital-based cross-sectional study examined whether routinely measured serum alkaline phosphatase can indicate osteoporosis risk in adults undergoing health checks. Higher ALP levels, even within the normal range, were associated with greater osteoporosis likelihood, particularly in younger, female, and metabolically healthy individuals.

Poor dietary iron weakens lung memory T cells after flu infection

Dietary iron deficiency in mice alters lung T cell activation during influenza infection and leads to memory T cells that are present in normal or increased numbers but have impaired antiviral cytokine responses. These functional deficits are most pronounced in lung CD8-positive memory T cells and persist even under optimal recall conditions.

Insufficient sleep may decrease life expectancy

A good night's sleep is more than a luxury: New research from Oregon Health & Science University suggests that insufficient sleep may shorten your life.

Researchers discover a surprising ally in the fight against insulin resistance and type 2 diabetes

An international research team led by Professor Marc-Emmanuel Dumas at Imperial College London & CNRS together with Prof. Patrice Cani (Imperial & University of Louvain, UCLouvain), Dr. Dominique Gauguier (Imperial & INSERM, Paris) and Prof. Peter Liu (University of Ottawa Heart Institute) has uncovered a surprising ally in the fight against insulin resistance and type 2 diabetes: a microbial metabolite called trimethylamine (TMA).

Virtual diet and exercise program shows promise in reducing lymphoma treatment side effects

Patients undergoing treatment for lymphoma often experience adverse side effects that can be so severe that they stop or slow treatment.

Kiwifruit intake boosts vitamin C in skin and supports dermal structure

Study shows that increasing dietary vitamin C intake with kiwifruit raises vitamin C levels in both the dermis and epidermis through active transport from the bloodstream. Higher skin vitamin C levels were associated with increased skin density and epidermal cell proliferation, but not with improved UV protection or measurable increases in new collagen markers.

Early exposure to fat-related food smells increases lifelong obesity risk

Early exposure to fat-related food odors during development alters central sensory processing and metabolic regulation, independently of maternal obesity or nutrient intake. These sensory cues program long-term susceptibility to obesity, impaired thermogenesis, and altered brain responses to dietary fat in adulthood.
