Does junk food in childhood leave lasting effects on the brain? Binge-eating habits persist into adulthood; published in a Nature journal, mice successfully normalized with gut bacteria: Innovative Tech

Irish researchers reported in Nature Communications that a high-fat, high-sugar diet in early life can leave lasting overeating and sugar-craving tendencies in adult mice, even after they return to a normal diet.

The effects were linked to changes in the hypothalamus, the brain region that helps regulate appetite, and showed sex-specific differences.

Two gut-based interventions — prebiotics and Bifidobacterium-related probiotics — helped improve disrupted eating behavior as well as related metabolic and neural pathways.

The findings suggest childhood diet can shape adult feeding behavior long after weight normalizes, while also pointing to the gut as a possible route for intervention.
