Nicotinic acid protects the liver from ischemia-reperfusion injury

In a new study published in Liver Research, a team of researchers in China discovered that nicotinic acid-a common form of vitamin B3-can dramatically reduce liver damage caused by ischemia-reperfusion injury (IRI), a major complication in liver surgery and transplantation.

Vitamin A derivative suppresses immune response and cancer vaccine efficacy

Scientists at the Princeton University Branch of the Ludwig Institute for Cancer Research have identified novel mechanisms by which a metabolic derivative of vitamin A-all-trans retinoic acid-compromises both the body's normal anti-cancer immune response and, in a different context, the efficacy of a promising type of cancer vaccine.

Periodontal bacterial load associated with disease severity in multiple sclerosis

Increasing evidence suggests that the severe gum disease, periodontitis, may contribute to central nervous system disorders through chronic inflammation.

Blood metabolite profiling outperforms BMI in predicting pregnancy complications

This study shows that a blood-based metabolomic signature linked to maternal BMI predicts gestational diabetes and preeclampsia more strongly than BMI alone, particularly in late pregnancy. A subset of 16 metabolites statistically mediates the BMI–gestational diabetes association, highlighting metabolic pathways that may improve prenatal risk stratification.

Folate deficiency drives genetic changes linked to lung cancer

Genetic alterations lie at the heart of cancer development, but scientists may have been overlooking a powerful driver of these changes—the everyday nutrients that feed our cells.

Strong heart health lowers long-term death risk in cancer survivors

Higher Life’s Simple 7 cardiovascular health scores were associated with lower long-term all-cause and cancer mortality in cancer survivors from a large Italian cohort. Inflammation, resting heart rate, and vitamin D statistically explained a substantial share of these associations, supporting shared cardiometabolic pathways across cancer and cardiovascular disease.

Sitting harms blood vessel function, but cocoa flavanols can stop it

This study shows that cocoa flavanols can preserve endothelial function during sitting, suggesting dietary strategies to mitigate cardiovascular risks.

Early life gut microbiome crucial for immune system development

Antibiotics are powerful treatments that have saved countless lives over the course of decades. New findings from Scripps Research have identified a way to preserve healthy immune development even when infants need antibiotic treatment.

What Americans eat is driving global nutrition research

WWEIA data, a cornerstone of national dietary surveillance, drives nutrition research and policy, enhancing understanding of dietary trends and health outcomes.

Mediterranean diet and healthy habits improve cancer survival rates

Being more physically active, following a balanced diet, not smoking, and keeping body weight and blood pressure under control: the same habits that protect the heart also prove decisive after a cancer diagnosis.

Plant-based diets support healthy growth when properly planned for children

Vegetarian and vegan diets can support healthy growth when carefully planned with appropriate supplementation, finds a major new meta-analysis – the most comprehensive study to-date of plant-based diets in children.

How specific foods reshape oxidative stress responses during and after high-intensity training

Carbohydrate-rich foods blunt acute oxidative stress during fasted high-intensity exercise, while polyphenol-rich foods accelerate early recovery by reducing post-exercise ROS. Findings highlight how nutrient timing shapes redox responses in sedentary young women undergoing resistance-circuit HIIT.

Study offers insight into how coffee and tea intake may influence bone health in older women

A new study from Flinders University offers insight into how two of the world's most popular beverages, coffee and tea, may influence bone health in older women.

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.

Triaptosis could be a promising strategy in the fight against cancer

Cancer remains one of the most critical global public health challenges, exerting profound social, economic, and clinical burdens while limiting gains in human life expectancy.

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.

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.

Why potatoes and grains can’t replace each other in a healthy diet

White potatoes are nutrient-rich, offering potassium and vitamins. Replacing grains with them may reduce essential nutrients like iron and folate.

Global data show why gut microbiomes in industrialized regions look increasingly alike

Researchers studying more than 1 000 adults across 12 countries found that industrialization is one of the strongest forces reshaping the human gut microbiome, reducing diversity and stability. Industrialized and urban populations also showed higher immune and gut stress markers, suggesting physiological consequences of these altered microbial communities.
