Childhood sugar intake may impact mental health later, UK study finds

A British study has uncovered a potential link between sugar consumption during a child's first 1,000 days and mental health issues in adulthood, with notable gender differences. Researchers from the University of Surrey examined health data from over 46,000 individuals born in Britain during post-World War II sugar rationing. The study, published in Translational Psychiatry, revealed that limited sugar intake from pregnancy until a child's second birthday correlated with a reduced risk of anxiety disorders later in life.

Conversely, women who consumed high levels of sugar during early childhood faced a greater risk of developing anxiety disorders in adulthood. To investigate further, the researchers conducted MRI scans on around 6,000 participants and found differences in brain structure based on sugar consumption patterns. Notably, early-life sugar intake appeared to influence the volume of grey matter in the brain, with significant variations observed in 11 brain regions, including the cerebellum, which plays a crucial role in mental health.

The study concluded that early-life diet may significantly impact mental health in later life stages.
