Key Takeaways

Consuming less sugar before birth and during the first 1 to 2 years of life was tied to a lower risk of dementia decades later, U.K. Biobank data showed.

The study used the abrupt end of World War II rationing as a natural experiment to test whether early-life sugar exposure was associated with late-life dementia.

Previous research has linked early-life sugar rationing to less risk of diabetes and hypertension in adults and better cardiovascular outcomes.
