How ultra-processed foods shape Crohn’s disease risk and what dietary strategies can really help

This narrative review synthesizes evidence showing that higher intake of ultra-processed foods is consistently associated with increased Crohn’s disease risk, with mechanistic pathways implicating emulsifiers, carrageenan, maltodextrin, titanium dioxide, sweeteners and salt. It also highlights that minimally processed dietary strategies, including EEN and CDED, show therapeutic promise, particularly in pediatric Crohn’s disease.

Supportive marriages may shape appetite control through oxytocin and the brain–gut axis

Supportive marital relationships are associated with lower BMI, fewer food addiction symptoms, higher oxytocin, stronger frontal brain responses to food cues, and favorable gut tryptophan metabolites. These coordinated social, neural, hormonal, and gut pathways suggest a plausible biological link between emotional support and healthier eating regulation.

Poor dietary iron weakens lung memory T cells after flu infection

Dietary iron deficiency in mice alters lung T cell activation during influenza infection and leads to memory T cells that are present in normal or increased numbers but have impaired antiviral cytokine responses. These functional deficits are most pronounced in lung CD8-positive memory T cells and persist even under optimal recall conditions.
