UK wartime sugar rationing data links limited early sugar intake to lower dementia and cancer risk

Scientists analysed health outcomes of people born in the UK during wartime sugar rationing, which ended in September 1953, comparing them with those born shortly after. The data suggest that limited sugar intake early in life is associated with a lower risk of dementia and cancer in later years. The rationing period provided a rare natural experiment for studying the long-term effects of diet on health.
