As more Americans embrace anxiety treatment, MAHA derides medications

After a grueling year of chemotherapy, surgery, and radiation to treat breast cancer, Sadia Zapp was anxious — not the manageable hum that had long been part of her life, but something deeper, more distracting.

Researchers show red blood cells drive better glucose tolerance at high altitude

Chronic hypoxia improves glucose tolerance in mice through insulin-independent mechanisms, with red blood cells acting as a major systemic glucose sink. Increased erythrocyte production and altered glycolytic flux help reduce circulating glucose while supporting oxygen delivery to tissues.

Study reveals unexpected role of TMC proteins in deafness

Proteins long known to be essential for hearing have been hiding a talent: they also act as gatekeepers that shuffle fatty molecules across cell membranes.

Single prenatal exposure to fungicide linked to disease across 20 generations

A single exposure to a toxic fungicide during pregnancy can increase the risk of disease for 20 subsequent generations - with inherited health problems worsening many generations after exposure.

Short anti-junk food ads cut adult cravings

Research reveals how ad length and framing impact junk food cravings, offering insights for effective public health campaigns targeting different BMI groups.

Low-fiber diets quickly impair emotional memory in aging brains

Past studies in animals have shown that a highly processed diet is linked to memory problems and inflammation in the aged brain – and the effect can happen fast, after just three days of poor eating.

Hypoxia rewires red blood cells to clear excess glucose

In a 2023 paper on hypoxia and glucose metabolism, our lab showed how organisms rewire their metabolism to adapt to low oxygen levels-such as those found at high altitudes.

Gut microbiome may shape response to GLP-1 drugs, new review suggests

This review examines how GLP-1 receptor agonists and the gut microbiome influence one another through bile acid signaling, short-chain fatty acids, and inflammatory pathways. It explores how microbial composition may shape treatment response and highlights the need for controlled human studies to enable microbiome-informed precision therapy.

Gut bacteria patterns help predict insulin resistance in type 2 diabetes, study finds

Researchers used 16S rRNA sequencing and machine learning to identify gut microbiome patterns associated with insulin resistance severity in people with type 2 diabetes. XGBoost models showed that specific bacterial genera, including Bacteroides and Faecalibacterium, help distinguish individuals with higher insulin resistance from healthy controls.

Prenatal infection increases risk of alcohol misuse in adulthood

Exposure to infection and other immune stress in the womb increases the likelihood of alcohol misuse in adulthood, a risk that may be reduced through prenatal antioxidant treatment, a new Washington State University study shows.

Monthly produce prescriptions do not improve blood sugar

Findings from a study on produce prescriptions show no significant improvement in blood sugar control, emphasizing the importance of addressing food insecurity.

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.

Can mobile apps change how we eat?

Evaluating digital tools for sustainable eating, the review highlights initial positive impacts but stresses the importance of long-term effectiveness research.

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.
