Trial finds prunes do not outperform calcium and vitamin D for male bone density

A one-year randomized trial found that daily prune supplementation did not improve total or lumbar spine bone mineral density in older men susceptible to, or with, osteopenia. Although some bone turnover biomarkers differed between prune and control groups, these changes did not translate into measurable bone density benefits beyond calcium and vitamin D3 supplementation.

Western diet weakens the gut’s nervous system through iron-dependent damage

A JCI study found that exposure to a Western diet in mice and to palmitic acid in murine and ex vivo human enteric nervous system models triggered ferroptosis, characterized by iron loading, lipid peroxidation, mitochondrial stress, and enteric neuronal loss. Boosting Nrf2 signaling protected enteric neurons and prevented Western diet-induced delayed colonic transit in mice, pointing to a potential pathway linking dietary fat exposure to gut motility dysfunction.
