Early-Life Sugar Reduction Linked to Lower Dementia Risk Later
An observational study of 64,737 people in the UK, born around World War II sugar rationing, found that those with less sugar exposure before birth and in the first one to two years had a roughly 21–23% lower risk of developing dementia and were diagnosed later by about 2.6 years on average. Brain imaging showed greater gray matter and fewer signs of brain tissue damage in the lower-sugar group. The study shows association, not causation, and further research is needed to understand mechanisms and public health implications.
