Can diet influence thyroid disease? A major review points to Mediterranean-style eating

This review found that thyroid health depends on more than iodine alone, with selenium, iron, zinc, vitamins, omega-3s, and overall eating patterns all shaping thyroid function and autoimmunity. It also concluded that Mediterranean-style diets are linked to more favorable thyroid outcomes, while unnecessary restrictive diets offer little benefit without a clear medical indication.

Prickly pear may pack a surprising punch against metabolic syndrome

This narrative review examines how Opuntia ficus-indica fruit, or prickly pear, may help target multiple features of metabolic syndrome through its fiber, betalains, polyphenols, carotenoids, and other bioactive compounds. The authors conclude that the fruit shows promising mechanistic and preclinical potential, but stronger human trials are still needed before firm clinical claims can be made.

Uncovering the hidden retinal risks of modern dentistry

Dentists are exposed to intense lighting for long hours, but its long-term impact on eye health is often overlooked. This study evaluates whether chronic exposure to dental lighting, especially blue and white LEDs, can damage the retina and disrupt its normal function. By combining human data with advanced imaging and animal models, the research uncovers hidden occupational risks and highlights the need for safer lighting practices to help protect dentists' vision.

How gut imbalance may drive obesity, diabetes, and heart disease

A new review argues that gut dysbiosis is closely linked to metabolic dysfunction through intertwined effects on inflammation, oxidative stress, gut barrier integrity, microbial metabolites, and epigenetic regulation. It also highlights microbiome-targeted strategies such as high-fiber diets, probiotics, prebiotics, postbiotics, exercise, and fecal microbiota transplantation as promising ways to support metabolic health.

Higher sugar intake raises gallstone risk in adults, study finds

A cross-sectional NHANES study of 8,975 U.S. adults found that higher total dietary sugar intake was associated with higher odds of gallstones, with each 100 g/day increase linked to a 41% rise after full adjustment. The findings suggest sugar intake may be a modifiable gallstone risk factor, but the study relied on self-reported gallstones and cannot establish causation.

$Heart health linked to higher fracture risk in postmenopausal women$

Heart health linked to higher fracture risk in postmenopausal women

Postmenopausal women face a high risk of bone fractures. Due to declines in estrogen levels, which can lead to an increased risk of osteoporosis, even a low-impact fall can result in a serious hip, back or wrist injury.

Heavily processed foods may raise heart disease risk beyond poor nutrition alone

A 2026 review in Cardiology in Review reports that higher intake of ultra-processed foods is consistently associated with greater risks of cardiovascular disease, stroke, and cardiovascular mortality across cohort studies and meta-analyses. The paper also highlights plausible mechanisms involving gut dysbiosis, oxidative stress, and NF-κB-driven inflammation, with additives such as emulsifiers, preservatives, dyes, and sweeteners discussed as potential contributors.
