Childhood junk food may rewire the brain for life
A recent study indicates that consuming junk food during childhood can lead to lasting changes in brain function related to appetite control. These changes may persist even after switching to a healthier diet, potentially increasing the risk of obesity later in life. However, the research suggests that certain gut bacteria and prebiotic fibers could help mitigate these long-term effects.
- ▪Children who consume high-fat, high-sugar foods may experience lasting brain changes that affect appetite control.
- ▪The study found that beneficial gut bacteria and prebiotic fibers can help reduce some of the negative impacts of early unhealthy diets.
- ▪Researchers linked changes in feeding behavior to disruptions in the hypothalamus, a brain region responsible for regulating appetite.

Science News from research organizations Childhood junk food may rewire the brain for life Date: May 21, 2026 Source: University College Cork Summary: Eating too much junk food early in life may rewire the brain in ways that last into adulthood, even after switching to a healthier diet. Scientists found that high-fat, high-sugar diets changed feeding behavior and disrupted appetite-control regions in the brain. Excitingly, certain gut-friendly bacteria and prebiotic fibers appeared to help undo some of the damage.
