Ultra-processed foods linked to brain changes and weight gain

Recent research highlights the neurological and metabolic risks associated with high consumption of ultra-processed foods. A study involving adults aged 35 to 69 utilized MRI scans to demonstrate that high intake of these foods correlates with increased body fat and liver fat. These metabolic changes are linked to cerebrovascular damage, including white matter lesions and small vessel disease, which may compromise neural integrity.

In children, the BrainChild study observed that higher daily intake of ultra-processed foods is linked to stronger neural activity in the dorsal striatum—a brain region responsible for reward processing—when viewing food images. This heightened reward response in children aged seven to 10 was directly correlated with increases in body fat over a one-year period. Researchers note that the developing brains of children are particularly sensitive to the food environment during this phase.
