Researchers followed 3,990 Dutch children for an average of 1.6 years and found that higher healthful plant-based diet scores were associated with modestly lower blood pressure and total cholesterol. Children with higher unhealthful plant-based diet scores had lower estimated food costs and distinct metabolite profiles, while healthful scores showed no clear cost association.

A study of more than 800 fast-food customers suggests that loyalty to a brand is shaped not only by satisfaction with the product or service but also by customers' emotional experiences. The study, published in the International Journal of Internet Marketing and Advertising, focused on fast-food consumers in Peru but could have implications for fast-food brands in other emerging markets.

While the Discovery Channel's annual Shark Week event has given the public greater familiarity with sharks, much about them—from their mysterious love lives to how their eating habits bring them into conflict with recreational anglers—remains a mystery to scientists. Now, two new studies led by researchers from the University of Massachusetts Amherst peer into these important aspects of shark biology to help guide real-world conservation strategies.

More than 93,000 visible appearances of brands promoting unhealthy food and drink, alcohol, gambling and speculative products were recorded during coverage of the largest FIFA World Cup in history, new research has found. Unhealthy food and drink brands accounted for more than seven in 10, with 65,722 appearances.

Researchers assessed the nutritional quality and environmental impacts of product portfolios from 44 major UK food and beverage manufacturers, covering 51.5% of the retail market. Their modelling showed that targeted changes to existing product lines could capture a substantial share of the potential nutrition and environmental gains for some manufacturers, although broader food-system changes would still be required to meet national and societal targets.

A large Australian randomized trial of 2,137 pregnant women tested whether substantially increasing egg and peanut consumption during pregnancy and breastfeeding could prevent food allergy in infants with a strong family history of allergic disease. Higher maternal intake did not significantly reduce IgE-mediated egg or peanut allergy at 1 year, although the lower-than-expected allergy rate limited statistical power and the results could not exclude a clinically important benefit.

Leading UK food and drink manufacturers could significantly improve the overall nutrition and sustainability of their products by making changes to 10% or less of their existing product line, according to new research in Nature Food.

A simple change in when people eat may offer a promising new approach for Huntington's disease, according to research led by Oregon Health & Science University.

Australia's farm sector currently faces a double whammy from weather and nonweather-related factors: a confirmed El Niño effect and surging inflationary pressures.

A kimchi-derived bacterium can bind to nanoplastics under gut-like conditions and may help carry them out of the body. In mice, the probiotic more than doubled the amount of nanoplastics detected in feces, pointing to a surprising potential use for microbes from fermented foods.

Damage to nuclear DNA occurs constantly, and near all of it is immediately repaired. A tiny fraction lingers, however, and over time a burden of mutational damage builds up in tissues throughout the body. It is an open question as to how large a component of degenerative aging is a direct result of this damage, under normal circumstances. High rates of mutation in individuals with disabled DNA repair mechanisms shorten life span and accelerate the onset of age-related conditions, sometimes dramatically, but that doesn't necessarily mean the DNA damage is important in aging at levels exhibited in normal individuals. The best approach to firm data is to find a way to suppress or repair mutations without affecting other mechanisms, but the life-extending interventions that are […]

A ketogenic diet paired with weight loss improves liver health more than a Mediterranean or very low-fat diet with similar weight loss in people with metabolically unhealthy obesity.

An international multidisciplinary panel developed consensus-based recommendations for GLP-1 receptor agonist use in people with eating disorders, calling for screening, individualized monitoring, patient education, and further research into safety and potential therapeutic effects. The experts cautioned that current evidence remains limited and inconsistent, particularly outside binge eating disorder, and identified major gaps in understanding the risk of new or recurrent eating disorders during treatment.

Spekboom (Portulacaria afra) is an easy-to-grow succulent shrub, small tree or hedge. In the wild, it grows naturally as tall as five meters (16 feet) on steep slopes and rocky hillsides in the Karoo and Eastern Cape regions of South Africa, where it helps stabilize soil and prevent erosion. It's also a champion of carbon sequestration—removing carbon dioxide from the atmosphere.

Eating more ultra-processed foods was linked to greater fat buildup inside thigh muscles, according to MRI scans of 615 adults at risk for knee osteoarthritis. Surprisingly, the association remained even after researchers accounted for calorie intake, physical activity, and other factors. Fatty changes in these muscles may weaken support around the knee and potentially increase osteoarthritis risk.

A new species of snake that feeds exclusively on birds' eggs has been discovered in the Harenna Forest in Ethiopia, one of the last substantial tracts of natural forest left in the Horn of Africa.

A study by DZNE finds that healthy eating is associated with slower biological aging-and that there is more than one way to eat healthily.

Analysis of dietary data from 1,655 Finnish adults found that usual food intake often differed substantially from the quantitative targets later set by the Nordic Nutrition Recommendations 2023. Plant-based foods were generally underconsumed, while red and processed meat and dairy intake frequently exceeded study targets, with adherence varying by sex, education, physical activity, age, and energy intake.

Researchers analyzed 236 blood metabolites in 421 children to examine metabolic signatures associated with three dietary patterns characterized by core foods, animal protein sources, or poor-quality fats and sugars. The results identified distinct, biologically plausible metabolite patterns across dietary exposures, although most individual associations did not survive multiple-testing correction and require validation in independent cohorts.

Rice and lentils are a pairing that goes a long way back, whether as khichdi in India or mujaddara in the Middle East. On its own, each is a source of incomplete protein, short on certain essential amino acids—but paired together, they fill each other's gaps, and lentils also blunt white rice's high glycemic index.

Global consumption of fertilizer has doubled since 1980, but some regions that have historically overused fertilizer, including China and parts of Europe, have taken steps to reduce use. Those are some of the findings of a new global dataset from the University of Minnesota's Institute on the Environment.

An unhealthy Western-style diet was associated with a faster cognitive decline in people with a genetic risk of Alzheimer's disease, according to new research led by Murdoch University and Alzheimer's Research Australia.

Using data from more than 21,800 adults in two UK birth cohorts, researchers found that lifetime psilocybin and LSD use was associated with stronger pro-environmental attitudes and a greater likelihood of following a vegetarian diet, with psilocybin showing the clearer dietary pattern. Mediation analyses suggested that environmental attitudes statistically accounted for the psilocybin-vegetarianism association and part of the association with lower red meat consumption, but the observational design cannot establish causation.

In a Denver cohort of 114 healthy infants, higher ultra-processed food intake during complementary feeding was associated with greater added sugar and sodium intake at 9 and 12 months. UPF intake showed no consistent relationship with growth through 12 months, while dietary diversity was not reduced among infants consuming more UPFs.

A pooled analysis of individual data from five time-restricted eating trials involving 124 adults linked shorter eating windows with modestly greater weight loss. Eight-hour TRE was associated with greater weight loss than 12-hour TRE and controls, while cardiometabolic outcomes showed no consistent relationship with eating-window duration and several weight associations weakened after adjustment.

Across one cafeteria field experiment and three scenario-based studies, low-arousal background music was associated with a higher proportion of healthy food selections or stronger intentions to consume healthy foods than high-arousal music. In the scenario studies, perceived comprehension helped explain the relationship, while the final experiment found that both music conditions produced stronger healthy-food intentions than restaurant noise alone, with low-arousal music showing the greater benefit.

Floods, wildfires, conflicts, earthquakes, economic shocks, hurricanes or epidemics: These unexpected and often dramatic events affect people's lives and jobs, destroy crops, wipe out livestock and stored food, contaminate water, block roads, cut off communities and severely affect access to markets and food. This is a distressing picture—one expected to get much worse in the near future because of climate change and an increasingly polarized world. Yet science says no: These natural and human-made shocks do not have to lead to more hunger by default.

People who like the taste and smell of onions are more likely to have lower blood pressure and

A laboratory study tested how ultra-processed, unprocessed, and mixed diets affected survival in 127 lobster cockroaches, Nauphoeta cinerea. Cockroaches fed only ultra-processed foods had higher mortality than those given unprocessed or mixed diets, although the study could not determine whether processing, ingredients, nutrition, or differences in food intake caused the effect.

The promising findings offer the first evidence that time restricted eating could become another tool for managing the condition.

Screening for eating disorders may help clinicians identify when food avoidance in patients with allergies extends beyond necessary dietary restrictions.

A study found people who had their drinks "very hot" had around a three times higher risk of the cancer than "warm" tea or coffee drinkers.

Switching to a more sustainable diet could halve food-related emissions in cities such as Amsterdam, while in cities such as Dhaka and Delhi, the focus should be more on making food production more sustainable as they widen food access. A new database by Leiden researchers shows that different cities need different approaches to achieve a more sustainable food system.

The CAA says passengers may still have a right to food and accommodation even when flight compensation is not payable.

The human body fights staph infections by starving it of essential nutrients. Staph, it turns out, is remarkably good at changing what's on the menu. Staphylococcus aureus—the infamous agent behind MRSA and most staph infections—needs sulfur to build proteins and other materials essential for survival. In a new Michigan State University study, published in the Journal of Bacteriology, researchers found the bacterium can adjust its diet depending on what sources remain available.

Mutations are changes in the molecular "letters" that make up DNA, the genetic blueprint for cells. Mutations build up with age in every cell when DNA is damaged or when cells make mistakes in fixing or copying it.

How will global access to food, water and energy evolve in coming decades? A new study coauthored by MIT researchers suggests the answers could be very different depending on region, resource and income.

Small mammals called plateau pikas are often treated as pests because they compete with livestock for food, but research from China shows they can improve the quality of vegetation for grazing yaks.

Packaged food usually sits in plastic-lined bags designed to keep air, moisture and contaminants out. That same protection can also increase the chances of chemicals from the packaging seeping into the food. When a chemical raises health concerns, industries often swap it for a molecular cousin, a substitution that may either be genuinely safer or simply be too understudied to know whether it is harmful. With thousands of chemicals in use, one-by-one regulation can't keep pace, so untested replacements can slide through unchecked.

A breast milk diet for infants is associated with a dose-response relationship to lower triglyceride levels in mothers.

Teenagers who come from households with a lower income and lower level of education are more likely to have an eating disorder, finds a new study co-led by UCL researchers.

A prospective study of 252 mother-child pairs found that higher combined maternal fruit and vegetable intake during pregnancy was associated with lower odds of overweight or obesity in children at age four. Total and natural fruit juice showed no association, whereas higher commercial fruit juice intake was associated with increased odds, though the authors emphasized that this finding was exploratory.

Activists spearheading calls for food labelling said a government proposal to have red warnings only when two concerning nutrients are high created ⁠an "industry-friendly loophole".

Researchers analyzing 1,404 pregnant women in Germany identified four distinct dietary patterns that differed substantially in maternal BMI, socioeconomic status, age, and gestational weight gain. A vegetable-rich pattern was also associated with selected neonatal measures, including greater birth length, but most newborn associations were modest or nonsignificant, and the observational study cannot establish causality.

In a paper published in the journal Marine Pollution Bulletin, researchers at Kyushu University report on what happens when wharf roaches, a common shoreline scavenger, eat expanded polystyrene (EPS). Roaches that fed on EPS showed no significant reduction in lifespan, but their guts displayed altered expression of genes involved in chemical defense, DNA repair and digestion. Analysis of the wharf roach gut microbiome showed little change, but several rare microbes were found only in the EPS-fed specimens.

Feeding stations providing food and water for wild birds are contributing to the spread of disease-causing parasites among farmland birds, researchers have said, with birds three times more likely to catch a parasite from these resources.
