Study Links Britain’s Sugar Rationing to 69% Lower Liver Cancer Risk and 2.2 Years Slower Aging

Summary
More time under Britain’s postwar sugar rationing during the first 1,000 days of life was linked to lower rates of five cancers decades later, in a study of more than 64,000 people born between 1951 and 1956.
September 1953 ended rationing and nearly doubled sugar consumption, creating a natural experiment in which children born months apart had sharply different sugar exposure in the womb and before age 2.
Liver cancer showed the biggest effect at about 69% lower incidence, while breast cancer was 36% lower; researchers said the gaps emerged only decades after rationing ended.
Telomere data and lower Granzyme B levels also pointed to slower biological aging, with the difference equivalent to roughly 2.2 years.
Around age 50, those exposed to more rationing still ate less sugar and had healthier diets, suggesting early sweetness exposure may shape lifelong taste preferences and later disease risk.
