Can dietary supplements support nutrition security as climate change disrupts food systems?

Environmental change is reshaping food availability, nutrient quality, and health risks, exposing major gaps in how nutrition science addresses climate-related stressors. This perspective argues that dietary supplements may have a context-dependent role but require rigorous, interdisciplinary research before informing public health action.

Teen girls who play organized sports show lower breast cancer risk biomarkers

This cross-sectional study of 191 adolescent girls found that ≥2 hours of organized recreational physical activity in the past week was associated with lower breast percent water content and reduced oxidative stress. These biomarkers are linked to breast cancer risk, although causality and long-term outcomes cannot be inferred.

Research suggests bamboo-based foods could support metabolic health

This systematic review synthesizes human, in vitro, and food-processing studies on bamboo consumption, finding limited but suggestive evidence for metabolic, digestive, and antioxidant benefits when products are properly prepared. It also highlights safety considerations, including potential goitrogenic effects from inadequately processed shoots, and calls for higher-quality human trials.

Sub-lethal water disinfection can unintentionally boost the spread of antibiotic resistance

The study reveals that environmental stressors do not merely kill bacteria; they can also prime surviving cells to take up resistance genes more efficiently, raising concerns about how antibiotic-resistant bacteria may spread in aquatic environments.

Parkinson’s disease may stem from iron starvation rather than iron overload

This perspective argues that Parkinson’s disease may involve functional iron deficiency, where bioavailable iron is limited despite normal or elevated total iron in the brain. The authors propose that iron sequestration, not iron toxicity alone, may impair dopamine synthesis and neuronal survival.
