Intermittent calorie restriction proves as effective as daily calorie cuts for type 2 diabetes

A post-hoc analysis of two clinical trials compared continuous calorie restriction with early time-restricted eating in adults with type 2 diabetes and overweight or obesity over three months. Both approaches improved weight, body composition, and metabolic health, with no clear superiority except for lower dropout with intermittent restriction.

Post-exercise milk helps protect bone density in adults over 60

The study highlights the role of milk and resistance training in improving bone health and physical performance among older adults through nutrition education.

Study links microbe-rich diets with better insulin and cholesterol markers

This exploratory Australian study developed a database to estimate live microbe content in foods and examined associations with cardiometabolic health indicators in adults. Higher intake of foods estimated to contain live microbes was linked with favourable markers such as higher HDL cholesterol and lower BMI, insulin, and waist circumference, although causality cannot be inferred.

Healthy diets link to longer life regardless of longevity genes, large study finds

Adherence to five established healthy dietary patterns was associated with lower mortality and modestly longer life expectancy in a large UK cohort. These associations were largely independent of genetic predisposition to longevity, suggesting diet quality may influence lifespan regardless of inherited risk.

Infant bifidobacteria may protect against childhood allergies

Certain gut bacteria in infants may reduce the risk of developing allergies later in childhood. This is the finding of new research from the ALADDIN study at Karolinska Institutet, published in Nature Microbiology.

High consumption of sugary drinks linked to anxiety symptoms in adolescents

A new study has identified an association between consumption of drinks containing a high amount of sugar and anxiety symptoms in adolescents.

Big breakfast study reveals protein curbs appetite but fiber delivers stronger gut microbiome benefits

A randomized crossover weight loss trial in adults with overweight or obesity found that higher protein big breakfasts improved satiety, while higher fibre breakfasts produced slightly greater weight loss and more favourable gut microbiota markers. Both diets improved metabolic biomarkers, but microbiota changes reflected surrogate gut health indicators rather than direct clinical outcomes.

Higher red meat intake links to greater diabetes odds in large US study

Higher intakes of total, processed, and unprocessed red meat were associated with greater odds of diabetes in a nationally representative sample of US adults. Statistical substitution models suggest replacing red meat with plant proteins, poultry, dairy, or whole grains may be linked to lower diabetes odds, though causality cannot be inferred.

Eating more plant-based foods may lower breast cancer risk, major international study indicates

Greater adherence to healthful plant-based dietary patterns was associated with lower breast cancer incidence and reduced all-cause mortality among women with breast cancer in large prospective cohorts. Specific micronutrients showed differential associations with cancer risk and survival, though findings remain observational and not causal.

Role of food nutrients in reducing oxidative stress linked to micro- and nanoplastics

This narrative review examines how micro- and nanoplastics may contribute to oxidative stress, inflammation, and metabolic dysfunction, including potential links with diabetes. It highlights plant-derived nutrients that activate the Nrf2 pathway as a possible strategy to enhance cellular stress resilience, although most evidence remains preclinical.

Study explores whether a bidirectional causal link exists between MASLD and sarcopenia

Metabolic dysfunction-associated steatotic liver disease (MASLD) and sarcopenia frequently coexist, yet their causal relationship and underlying mechanisms remain poorly defined.

Study: 71% of US grocery store baby food products are ultra-processed

An alarming 71 percent of grocery store baby food products in the United States are classified as ultra-processed foods (UPFs), according to new research published today in the scientific journal Nutrients.

Breastfeeding and healthy infant diets may help lower obesity risk by age nine

nationwide Icelandic cohort study found that better alignment with infant nutrition guidelines was associated with lower odds of obesity at ages 6 and 9 years. Associations were inconsistent at younger ages, highlighting the complex and multifactorial nature of childhood weight outcomes.

Early heart disease risk factors identified in South Asian adults in the U.S.

South Asian adults in the U. S. were more likely to have risk factors for atherosclerotic cardiovascular disease (ASCVD) by age 45 when compared to white, Black, Chinese or Hispanic adults in the same age group, according to a study published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Healthy low-carbohydrate and low-fat diets may improve cardiovascular health

The quality of a low-carbohydrate or low-fat diet may matter more than the amount of carbohydrates or fat consumed when it comes to reducing heart disease risk, according to a new study published in JACC, the flagship journal of the American College of Cardiology.

South Asian adults in the U.S. have higher prevalence of risk factors for heart disease

South Asian adults in the U.S. report doing many of the right things for heart health, yet they show significantly higher rates of prediabetes, diabetes and hypertension than white and Chinese adults, and higher than or roughly similar rates to Black and Hispanic patients, according to a new study led by Northwestern Medicine.

High-fat diets cause more damage to metabolic health than carbohydrates

In recent years, many media reports and social media influencers have emphasized the dangers of eating too many carbohydrates.

Eating fewer foods of concern may protect the heart beyond pills

A prospective cohort study in adults with hypertension and or hypercholesterolemia found that lower intake of ultra processed foods or foods flagged by front of pack nutrition warnings was associated with reduced cardiovascular disease risk. These associations persisted regardless of cardioprotective medication use, suggesting dietary quality contributes independently to cardiovascular prevention.

Stress hormones rewire immune system during periods of food scarcity

When food is scarce, stress hormones direct the immune system to operate in "low power" mode to preserve immune function while conserving energy, according to researchers at Weill Cornell Medicine.
