Reducing sodium in common foods could prevent heart disease and stroke

Lowering sodium in packaged and prepared foods could significantly improve cardiovascular health and prevent many cases of heart disease, stroke and deaths in the general population in France and the U.K., according to two new research studies published today in Hypertension, an American Heart Association journal.

Olive oil type matters for cognition and gut health in older adults

Higher intake of virgin and total olive oil was associated with modest but significant improvements in cognitive performance over two years in older adults with metabolic syndrome. These associations were partly linked to gut microbiota composition, with specific taxa such as Adlercreutzia contributing a small mediating effect.

Tiny plastic particles may interfere with brain processes implicated in Parkinson’s disease

Micro- and nanoplastics are increasingly detected in human tissues, including the brain, and experimental evidence suggests they can interact with biological pathways central to Parkinson’s disease pathology. This review synthesises mechanistic data indicating that plastic particles may influence protein aggregation, neuroinflammation, mitochondrial dysfunction, and the gut–brain axis, while emphasising the need for prospective human studies.

Three daily servings of full-fat dairy do not worsen weight or blood markers

This randomized 12-week trial examined whether adding three daily servings of full-fat dairy to diets aligned with Canada’s Food Guide affects body weight, cardiometabolic markers, and nutrient intake in adults with overweight or obesity. Full-fat dairy intake did not adversely affect weight, body composition, or metabolic health and increased calcium and protein intake, supporting dietary compatibility rather than therapeutic benefit.

New role for GLP-1 drugs: Improving survival in people with severe psychiatric disorders

This editorial argues that GLP-1 receptor agonists could substantially improve healthspan and reduce premature mortality in people with serious mental illnesses by targeting cardiometabolic risk rather than psychiatric symptoms alone. It highlights emerging evidence, safety considerations, and equity challenges that position GLP-1 RAs as a promising public health strategy for this high-risk population.

Why the age you start smoking matters as much as how much you smoke

Starting smoking at a younger age is associated with substantially higher risks of myocardial infarction, stroke, and death, even after accounting for cumulative smoking exposure. Early initiation also amplifies the cardiovascular harm of heavier smoking, indicating increased vulnerability when smoking begins in adolescence.

Structured assessment framework aims to ensure safe, ethical deployment of clinical LLMs

A new expert consensus made available online on 10 October 2025 and published in Volume 5, Issue 4 of the journal Intelligent Medicine on 1 November 2025, sets out a structured framework to assess large language models (LLMs) before they are introduced into clinical workflows.

Why medication abortion is the top target for anti-abortion groups in 2026

This week would have marked the 53rd anniversary of Roe v. Wade, the 1973 Supreme Court decision that legalized abortion nationwide — that is, until 2022, when the court overturned it. Since then, abortion has been banned in 13 states and severely limited in 10 others.

Early interventions help nonspeaking autistic children achieve speech gains

After receiving evidence-based early interventions, roughly two-thirds of non-speaking kids with autism speak single words, and approximately half develop more complex language, according to a new study led by researchers at Drexel University's A.J. Drexel Autism Institute.

Exercise variety, not just volume, is tied to longer life

Researchers analysed nearly three decades of data from more than 111,000 adults to examine whether the variety of physical activities people perform is linked to long-term survival. They found that engaging in a broader range of activity types was associated with lower all-cause mortality, independent of total exercise volume.
