Diet & Nutrition

Food and beverages provide the energy and nutrients you need to improve health, manage disease, and reduce the risk of disease. Complete nutrition requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity.

Fast answers and extra research drive AI healthcare use in America

One in four U.S. adults - the equivalent of over 66 million Americans - report having used artificial intelligence tools or chatbots for physical or mental healthcare information or advice, according to new research released today from the West Health-Gallup Center on Healthcare in America.

Researchers debunk the existence of the childhood "adiposity rebound" phenomenon

In new research to be presented at this year's European Congress on Obesity in Istanbul, Turkey (12-15 May) and published in The Journal of Nutrition, a 42-year old theory as to why children's body mass index (BMI) decreases post-infancy before then rising continuously from age six years –'the adiposity rebound' is refuted using new analyses – rather than decreasing body fat, the real reason is proposed as increasing muscle mass.

Scientists link poor sleep to decreased chemotherapy response via the gut

Sleep deprivation has long been known to weaken the immune system. Now UF Health Cancer Institute researchers have made a startling discovery: The gut microbiota drives changes to the immune system caused by chronic sleep loss. These changes promote cancer progression, disrupt circadian rhythm and weaken the effectiveness of chemotherapy.

Study explains the link between NDMA-contaminated water and childhood cancer

A new study from MIT suggests that a carcinogen that has been found in medications and in drinking water contaminated by chemical plants may have a much more severe impact on children than adults.

Psychedelic use is associated with major life changes across 10 domains

Researchers created a new questionnaire to measure major life changes linked to psychedelic use and found that most surveyed adults reporting naturalistic psychedelic use said psychedelics had influenced at least one major change in their lives. These changes most often involved goals, values, and spirituality, were usually rated positively, and were more commonly reported by people with more frequent use.

Study finds popular AI chatbots often give problematic health advice

Researchers audited five popular public-facing AI chatbots across 250 health prompts and found that 49.6% of responses were problematic, with especially weak performance on open-ended questions and in nutrition and athletic performance. The study also found poor citation quality, difficult readability, and very few refusals to answer, raising concerns about the reliability of chatbots for everyday health information.

Researchers discover a molecular signature to flag dysfunctional aging cells

UCLA researchers have identified a rogue population of immune cells that quietly accumulates in aging tissues and in the livers of people with fatty liver disease. Clearing these cells, they found, dramatically reduced inflammation and reversed liver damage in mice - even while the animals remained on an unhealthy diet.

BMI increases in early childhood may reflect muscle growth, not fat

A new study published in The Journal of Nutrition, a peer-reviewed journal of the American Society for Nutrition, offers new insights into a decades-old puzzle in childhood obesity. The study found that while body mass index (BMI) starts to rise in early childhood during a stage known as adiposity rebound, when BMI increases after an initial decline, the waist-to-height ratio, a measure that better reflects body fat, continues to drop. This suggests that the BMI increase at this age mainly reflects growth in lean tissues such as muscle and bone, rather than extra body fat.

New findings explain why eccentric training prevents common sprinting injuries

Hamstring injuries are among the most common injuries in sports, particularly in activities involving sprinting and rapid acceleration. They account for roughly 10 % of injuries in field-based sports and often result in significant time away from competition. Despite their frequency, the mechanisms underlying the effectiveness of certain training programs in preventing these injuries remain poorly understood.

Study links ultra-processed food intake to poorer thigh muscle quality

A Radiology study of 615 adults at risk for knee osteoarthritis found that higher ultra-processed food intake was associated with greater fat infiltration in thigh muscles on MRI, a marker of poorer muscle quality. The association remained after adjustment for BMI, was stronger in models using abdominal circumference, and did not differ significantly by sex.

Can processed meats fit into a healthy diet?

This perspective-style review argues that processed meats remain valuable sources of high-quality protein, essential amino acids, and bioavailable micronutrients despite concerns about sodium, fat, and chronic disease links. It also contends that much of the evidence tying processed meat to adverse health outcomes is observational and potentially confounded, while emphasizing the role of processing in safety, shelf life, and food security.

Are healthy foods really healthy? Nutrition researchers say context matters

This Clinical Nutrition opinion paper argues that nutrition research should stop asking whether a food is simply “healthy” and instead ask what it is being compared with. Because diets are compositional, the health effects of foods depend on the specific substitution, and the authors argue that causal inference and network meta-analysis can improve how evidence is interpreted.

Lower-protein toddler formula does not reduce BMI at age 2, trial finds

A large randomized trial in Germany and Spain found that lowering milk protein intake during the second year of life did not reduce BMI z-score at 24 months, though it did produce a temporary BMI reduction at 18 months. Lower protein intake also led to more stable weight and length trajectories, while higher protein intake pushed growth upward relative to WHO standards.

Older adults show high willingness for Alzheimer’s blood tests

Northwestern University psychologist Andrea Russell sees older adults with early cognitive impairment riddled with anxiety. Some worry a missed word or forgotten appointment could signal Alzheimer's disease.

Ultra-processed foods linked to higher obesity risk in adolescents

Adolescents who consume more ultra-processed foods (UPFs) have significantly higher odds of being overweight or obese, according to a new systematic review and meta-analysis published in the open-access journal PLOS One by Mekuriaw Nibret Aweke of the University of Gondar, Ethiopia, and colleagues.

Popular chatbots often provide inaccurate and incomplete medical information

A substantial amount of medical information provided by 5 popular chatbots is inaccurate and incomplete, with half of the answers to clear evidence based questions "somewhat" or "highly" problematic, show the results of a study published in the open access journal BMJ Open.
