Gut bacteria patterns differ in autism and siblings and link to social symptoms

This sibling-controlled East Asian study found that autistic individuals, their unaffected siblings, and typically developing controls differ in gut microbiota diversity and composition, with the clearest separation between autism and typical development. Specific taxa, particularly the butyrate-producing genus Anaerostipes, were modestly associated with social communication and internalising symptoms, supporting a gut–behaviour link without implying causality.

Many parents struggle to navigate conversations about nutrition with teens

As teens gain more independence in their food choices, many parents struggle to navigate conversations about nutrition -which could be especially important during the holidays, when celebrations often center around meals.

A new trial investigates whether the MIND diet can be scaled for obesity management

This study protocol outlines a 12-week randomized trial testing whether a MIND diet intervention is feasible, acceptable, and sustainable for adults with obesity in Sweden. It will generate preliminary evidence on adherence, mental well-being, and gut microbiota changes to inform larger efficacy trials.

Swapping high-carb snacks for tree nuts cuts food cravings in young adults at metabolic risk

Daily replacement of typical high-carbohydrate snacks with mixed tree nuts for 16 weeks reduced cravings for sweets and fast foods in young adults with early metabolic syndrome risk. This dietary swap improved overall diet quality, measured by the Healthy Eating Index, without increasing body weight or altering short-term glycaemic markers.

Single-cell RNA-seq reveals FBLN7's role in adipose tissue fibrosis

Fibrosis, resulting from excess extracellular matrix (ECM) deposition, is a feature of adipose tissue (AT) dysfunction and obesity-related insulin resistance.

Glycation stress drives aortic stiffening through oxidative stress and senescence

A new research paper was published in Volume 17, Issue 11 of Aging-US on November 14, 2025, titled "Methylglyoxal-induced glycation stress promotes aortic stiffening: putative mechanistic roles of oxidative stress and cellular senescence."

How ultra-processed foods shape Crohn’s disease risk and what dietary strategies can really help

This narrative review synthesizes evidence showing that higher intake of ultra-processed foods is consistently associated with increased Crohn’s disease risk, with mechanistic pathways implicating emulsifiers, carrageenan, maltodextrin, titanium dioxide, sweeteners and salt. It also highlights that minimally processed dietary strategies, including EEN and CDED, show therapeutic promise, particularly in pediatric Crohn’s disease.

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.

What happens to your body when you eat takeaway food too often?

This study of 8,556 US adults shows that frequent takeaway food consumption is associated with a higher energy-adjusted Dietary Inflammatory Index and adverse cardiometabolic markers. The findings suggest that reducing takeaway intake and lowering dietary inflammatory potential may improve long-term cardiometabolic health.

TikTok videos about gout often contain misleading information

A new paper in Rheumatology Advances in Practice, published by Oxford University Press, indicates that TikTok videos about gout are commonly misleading, inconsistent, or inaccurate.

White bread vs wholegrain: which one is actually better for your health?

This review dispels common myths about white and wholegrain bread by examining their composition processing and health effects. It concludes that while wholegrain breads offer added benefits white bread remains a safe affordable and nutritionally meaningful staple when fortified.

What happens to your body during an ultramarathon? New study reveals key metabolic changes

This study tracked ultramarathon runners across 100 km, 160.9 km, and 230 km events to examine real-world metabolic, hormonal, and muscle stress responses. Severe energy deficits, muscle damage, and heterogeneous hormonal shifts were observed, with the greatest strain seen in the 230 km distance.

How much omega-3 do you need daily? New global review reveals DHA and EPA requirements

Global and national guidelines for long-chain omega-3 intake vary widely across life stages, with many countries lacking clear recommendations. Most authorities advise at least 250 mg/day of EPA and DHA, yet population intakes remain far below optimal levels.

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.
