New research shows people born during postwar UK sugar rationing had a 35% lower risk of type 2 diabetes and 20% lower risk of high blood pressure, according to data from the UK Biobank. Studies led by Dr Jiazhen Zheng and others suggest low early sugar exposure also links to reduced risks of cardiovascular, liver, and respiratory diseases, plus dementia. The first 1,000 days under rationing appear to influence lifelong health, possibly through metabolic changes established early in life. Research continues to uncover how these early dietary differences affect ageing and mental health outcomes.

00:00Sugar rationing in post-war Britain cut type 2 diabetes risk by 35% for those exposed in their first
00:061,000 days.
00:07Researchers at Hong Kong University of Science and Technology and the University of Southern California studied health records from the
00:15UK Biobank.
00:16They found that people who grew up with limited sugar also had 20% lower risk of high blood pressure
00:22in midlife.
00:22The effects extended beyond heart health, linking to lower risks of liver disease, dementia, and even slower biological aging.
00:30Mental health also showed benefits, with a 33% lower risk of anxiety reported by those raised under rationing.
00:38Scientists say this natural experiment reveals how early nutrition shapes long-term health, but they caution it shows association, not
00:47causation.
00:47The findings suggest that keeping sugar intake near current UK guidelines could have lasting benefits decades later.
