Sugar Rationing Became a Natural Experiment
Exposure before birth and through infancy was associated with 21% to 23% lower dementia risk decades later.
Summary
Exposure before birth and through infancy was associated with 21% to 23% lower dementia risk decades later.
A Neurology study compared 64,737 people born around the end of UK sugar rationing and found lower dementia risk and an average 2.6-year delay among exposed groups. The historical analysis is observational and does not prove that early-life sugar directly prevents dementia.
Why it matters
