A study of 64,737 people born in Britain between 1951 and 1956 found that those rationed for sugar during their first 1,000 days had a 21% to 23% lower dementia risk.
Researchers from The Hong Kong University of Science and Technology observed that individuals rationed through age two developed dementia an average of 2.55 years later than non-rationed peers.
Brain scans of 7,724 participants revealed that the rationed group averaged 3 cubic centimeters more gray matter, suggesting a long-term protective effect against cognitive decline.
