Ultra-processed foods make up nearly half of US grocery purchases, raising public health concerns

A 2025 study of nearly 60,000 US households found that almost half of grocery purchases were ultra-processed foods (UPFs), with major disparities based on income, education, and race. Non-Hispanic white households led in UPF purchases, especially in beverages, reversing earlier trends.

Heart failure patients benefit from medically tailored meals after discharge

A new study, published in BMC Nutrition, demonstrates that providing medically tailored meals (MTM) to patients with heart failure (HF) and malnutrition risk following hospital discharge significantly improves their nutritional status and keeps hospital readmission rates well below local and national averages.

Chitosan clears microplastics from the gut in rats within days

A study in rats found that ingesting chitosan, a dietary fiber from shells, significantly increased the fecal excretion rate and decreased the gut retention time of polyethylene microplastics. This suggests chitosan could potentially help mitigate microplastic accumulation in the digestive system.

Mediterranean diet helps manage rheumatoid arthritis and Hashimoto’s, study shows

The Mediterranean diet shows promise in managing both systemic and organ-specific autoimmune diseases, including rheumatoid arthritis and autoimmune thyroiditis. Its anti-inflammatory and microbiota-modulating properties may reduce disease activity and improve metabolic outcomes.

New study questions poultry's health halo amid rising cancer risks

A new analysis from Italian cohort studies found that consuming over 300 g of poultry per week is linked to significantly increased risk of death from gastrointestinal cancers, especially in men. Moderate meat intake, particularly red meat in controlled quantities, was paradoxically associated with reduced all-cause mortality.

Do edible insects deliver on protein and sustainability? New study gives answers

Researchers from the University of Pisa analyzed 523 insect-based food products sold online in Europe, evaluating their species, formulations, and nutritional profiles. They found that these products, though diverse and protein-rich, face cultural resistance and high prices, limiting their dietary integration.

Metabolic syndrome in midlife linked to higher dementia risk

Having a larger waistline, high blood pressure and other risk factors that make up metabolic syndrome is associated with an increased risk of young-onset dementia, according to a study published on April 23, 2025, online in Neurology®, the medical journal of the American Academy of Neurology.

What links dust mites, shellfish, and insect food allergies?

A study of 634 allergy patients in Tenerife found that 22% were sensitized to edible insects—often without ever consuming them, due to cross-reactivity with house dust mites. Tropomyosin and arginine kinase were key shared allergens, but a subset reacted to unknown insect proteins, raising new concerns about emerging food allergies.

UK public backs food tax, if it makes healthy food more affordable

A nationally representative UK survey found that 48% of adults support taxing unhealthy foods, with support rising to 72% if revenues make healthy foods cheaper. Public backing was strongest among non-manual workers and Londoners, and weakest among lower-income and unemployed groups.
