Overview

Randomized trial finds reduced cancer incidence in individuals with early-life sugar restriction, suggesting lasting health benefits.

Key Points

  • To investigate whether early-life sugar exposure affects long-term cancer risk and biological ageing.
  • Analyzed data from 64,761 UK Biobank participants born between 1951 and 1956.
  • Used the end of UK sugar rationing in 1953 as a natural experiment to assess cancer incidence rates.
  • Examined the impact of early-life sugar exposure on dietary habits and biological markers decades later.
  • Participants with early-life sugar restriction showed reduced adult cancer incidence: liver (HR 0.31), rectum (HR 0.60), lung (HR 0.59), prostate (HR 0.48), breast (HR 0.64).
  • Rationed cohorts consumed less sugar and maintained healthier diets in adulthood.
  • Rationed cohorts had longer telomere length (+0.05 SD) and lower Granzyme B, indicating decreased biological ageing.
