This perspective-style review argues that processed meats remain valuable sources of high-quality protein, essential amino acids, and bioavailable micronutrients despite concerns about sodium, fat, and chronic disease links. It also contends that much of the evidence tying processed meat to adverse health outcomes is observational and potentially confounded, while emphasizing the role of processing in safety, shelf life, and food security.

This Clinical Nutrition opinion paper argues that nutrition research should stop asking whether a food is simply “healthy” and instead ask what it is being compared with. Because diets are compositional, the health effects of foods depend on the specific substitution, and the authors argue that causal inference and network meta-analysis can improve how evidence is interpreted.

A large randomized trial in Germany and Spain found that lowering milk protein intake during the second year of life did not reduce BMI z-score at 24 months, though it did produce a temporary BMI reduction at 18 months. Lower protein intake also led to more stable weight and length trajectories, while higher protein intake pushed growth upward relative to WHO standards.

Northwestern University psychologist Andrea Russell sees older adults with early cognitive impairment riddled with anxiety. Some worry a missed word or forgotten appointment could signal Alzheimer's disease.

A University of Calgary-led study has found evidence that children with genes predisposing to migraine might have an increased risk of having more headaches after a concussion, which are known to be linked to prolonged symptoms up to six-months after the injury.

Doctors recommend getting your flu shot annually, since the specific influenza strain it targets varies from year to year. But what if the shot could be more effective while protecting against more strains?

Adolescents who consume more ultra-processed foods (UPFs) have significantly higher odds of being overweight or obese, according to a new systematic review and meta-analysis published in the open-access journal PLOS One by Mekuriaw Nibret Aweke of the University of Gondar, Ethiopia, and colleagues.

A research team led by the University of California, Irvine's Joe C. Wen School of Population & Public Health has uncovered a critical biological link explaining why individuals with metabolic dysfunction–associated steatotic liver disease (MASLD), or fatty liver disease, face significantly worse outcomes from certain foodborne infections.

Frank Infurna first started thinking about the plight of middle-aged adults 10 years ago. He conducted a monthly survey, asking about their health, well-being, relationships, and life events.

Researchers at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) show that active mitochondria maintain dendritic cells, the immune system's sentinels, in a "ready-to-respond" state, linking cellular metabolism to gene regulation and T-cell activation.

Aston University bioscientist Dr John Reynolds has won a £125,000 Springboard grant from the Academy of Medical Sciences (AMS) for research into neurodegeneration caused by a rare genetic disease.

Timing exercise to match body clock chronotype-the natural predisposition to morning or evening alertness-may lower cardiovascular disease risk among those who are already vulnerable, suggests research published in the open access journal Open Heart.

Researchers at Toronto's Sinai Health have found that semaglutide – the active ingredient in popular weight loss drugs that mimic the gut hormone GLP-1 – acts directly on a subset of liver cells to improve organ function and does so independently of weight loss.

Left bundle branch area pacing was found to be an effective and practical strategy for cardiac resynchronization, according to a Late-Breaking Science presentation at EHRA 2026, the annual congress of the European Heart Rhythm Association (EHRA), a branch of the European Society of Cardiology (ESC).

Primary liver cancer continues to pose a major global health challenge, ranking as the third leading cause of cancer-related deaths worldwide.

What if some of the risk of anxiety and depression in children is not only about the genes they inherit, but also about their parents' genetic dispositions and how these influence the home environment?

With a new $6.2 million, five-year grant from the National Institute on Aging, researchers at Case Western Reserve University will use artificial intelligence (AI) and machine learning to identify possible genetic targets to treat Alzheimer's disease.

The growing use of electric bikes and scooters has caused a surge in brain and spine injuries among urban riders and pedestrians, a new study shows.

A long-standing mystery in cancer treatment is how tumor cells so often become resistant to drugs, even ones they have never encountered before.

Though many studies approach the developmental disorder Rett syndrome as a single condition arising from general loss of function in the gene MECP2, a new study by neuroscientists in The Picower Institute for Learning and Memory at MIT shows that two different mutations of the gene caused many distinct abnormalities in lab cultures.
