Southern Europe eats closest to the planetary diet, so why is diabetes so high?

Researchers comparing temperature trends, food supplies, and diabetes prevalence across Europe found that Southern Europe had the closest alignment with Planetary Health Diet recommendations, yet also recorded the highest and fastest-rising diabetes prevalence. The exploratory study found inconsistent relationships between warming, dietary composition, and diabetes across regions, suggesting that multiple environmental, lifestyle, and demographic factors warrant further investigation.

The Mediterranean diet has a modern problem, and it isn't just about food

A narrative review published in Applied Sciences examined how urbanisation, time constraints, food costs, and changing lifestyles have contributed to declining adherence to the Mediterranean diet. Drawing on 116 references, the authors identified workplace and school interventions, nutrition education, physical activity, and Mediterranean-inspired convenience foods as potential strategies for adapting this dietary pattern to modern life.

Engineered beneficial bacteria reduce bloodstream infections after stem cell transplants

Researchers at City of Hope®, one of the largest and most advanced cancer research and treatment organizations in the country, and collaborators have pioneered a new approach to preventing dangerous bloodstream infections in patients receiving donor stem cell transplants for blood cancers.

Compounds that give citrus fruits their scent may affect gut health

A review published in Food & Function found that dietary terpenoids, naturally occurring compounds in fruits, herbs, and vegetables, can suppress inflammatory signalling and improve intestinal barrier function in laboratory and animal studies. However, human evidence remains limited to two small studies of geraniol-based interventions for irritable bowel syndrome, with further research needed to establish clinical efficacy, appropriate dosing, and long-term safety.

Vitamin C supplements during pregnancy may support infant emotional health

New research from Oregon Health & Science University shows that additional vitamin C intake during pregnancy can be an effective, low-cost and accessible intervention to promote infant emotional well-being.

Eating sugary foods more than twice a week was linked to 28% higher breast cancer risk

In a prospective study of 71,264 Korean women followed for an average of 9.2 years, researchers identified 713 breast cancer cases and examined how different dietary sugar sources related to cancer risk. Women consuming high-sugar foods more than twice weekly had a 28% higher breast cancer risk than those consuming them no more than once a month, while total sugar intake and fruit consumption showed no significant association.

Two healthy diets stood out in a study of more than 7,000 adults

In a cross-sectional analysis of 7,256 adults from the Maastricht Study, researchers found that greater adherence to the DASH and Dutch Healthy Diet patterns was associated with higher very-low-frequency (VLF) heart rate variability power, particularly among participants not taking beta-blockers. No significant associations were observed across time-domain HRV measures after full adjustment, and the findings do not establish that these diets improve cardiovascular function.

The type of fiber you eat shapes how gut bacteria feed and work together

A 2021 review examined how the chemical structure and physical properties of dietary fiber influence which gut bacteria can break it down and how microbial species compete and cooperate during fermentation. The authors described how these interactions contribute to short-chain fatty acid production, while emphasizing the need for further research involving intact plant foods to understand their implications for human health.

Holistic family surroundings are essential for raising healthy children

A child's health is shaped by more than inherited genes or the food on the table. Family routines, relationships, cultural practices, and everyday conditions—from early school schedules to long commutes—also influence how children grow and thrive, according to an Ateneo de Manila University medical professor and clinician.

Why do we turn to comfort food? A survey of 1,203 adults offers clues

A cross-sectional study of 1,203 UK adults found that stronger expectations of positive emotions from high-fat, salt and/or sugar foods were weakly associated with poorer diet quality and more frequent comfort eating. Negative emotional expectations about many foods also tracked with comfort eating, but the study did not establish whether eating these foods actually changed mood.

Discarded fruit and vegetable parts offer overlooked fiber benefits

Most of us routinely discard the peels, skins, stalks, and seeds of fruits and vegetables at mealtime. But new research from King's College London suggests these scraps could be a valuable – and overlooked – source of dietary fiber, offering potential benefits for both public health and the environment.

Can broccoli sprouts help with insulin resistance? New review offers clues

A review published in the British Journal of Nutrition examines how carotenoids and bioactive compounds in Brassicaceae microgreens may influence obesity, insulin resistance, and type 2 diabetes through metabolic and inflammatory pathways. Small human trials involving broccoli sprouts have reported improvements in selected metabolic markers, but larger, longer-term studies are needed to establish their clinical benefits.

Plant and animal proteins show opposite effects on testosterone levels

Higher animal protein intake was associated with lower blood testosterone levels, while higher plant protein intake was associated with higher levels, according to a new study from the University of Eastern Finland.

High intake of saturated fat can promote favorable changes in cardiovascular risk markers

New analyses from the Norwegian randomized controlled trial CARBFUNC show that more than doubling saturated fat intake over a two-year period can promote favorable changes in several cardiovascular risk markers, without increasing apoB, the main suspected risk factor.

Fruits and vegetables may be a better option to improve kidney disease outcomes

In people with chronic kidney disease (CKD), oral sodium bicarbonate is a standard treatment for metabolic acidosis (too much acid buildup in the body), but results from a recent clinical trial indicate that dietary acid reduction with base producing fruits and vegetables may be a better option.

Nearly three in four popular comfort foods have something in common, researchers find

A US study examining 300 distinct comfort foods identified chips, ice cream, pizza, chocolate, and cookies as the most frequently nominated choices among adults. Researchers found that nearly three-quarters of the foods met hyperpalatability criteria, while approximately 43% were entirely ultra-processed under a strict classification, with relatively small nutritional differences across demographic groups.

Rice, fish and pickles: Is the traditional Japanese diet as healthy as we think?

A systematic review of 37 studies found that greater adherence to predefined Japanese-style dietary patterns was associated with lower all-cause and cardiovascular mortality, based on pooled evidence from three cohort studies. However, health associations varied according to dietary composition, suggesting that traditional Japanese diet scores alone may not adequately distinguish the potential benefits and risks of different food combinations.

Scientists found a link between Mediterranean diet blood markers and longer survival

Researchers found that a previously validated 67-metabolite blood signature of Mediterranean diet adherence was associated with lower long-term mortality across a Spanish trial population and three US cohorts. Participants with the highest signature scores had a 23% lower relative hazard of death than those with the lowest scores in both populations, although the findings do not establish a causal relationship.

Fruit and sugary drinks stood out in a three-year study of teenage mental health

A three-year study of 6,537 Australian adolescents found that higher fruit consumption was associated with a lower risk of elevated depression and anxiety symptoms, while greater sugar-sweetened beverage intake was associated with increased risk. Vegetable consumption showed no significant association with either outcome, and the observational findings cannot establish cause and effect.
