Listen to Story A new study suggests that reducing sugar intake in early life can have a lasting impact on health, potentially cutting the risk of chronic diseases like type 2 diabetes and hypertension by as much as 35% and 20%, respectively. Type 2 diabetes is a chronic condition where the body becomes resistant to insulin (hormone) or doesn’t produce enough, causing high blood sugar levels and increasing risks of heart disease and other complications. Hypertension, or high blood pressure, on the other hand, is a condition where blood flows through arteries at higher-than-normal pressure, straining the heart and blood vessels, and raising risks for heart disease and stroke.

The research published in the journal Science reveals that sugar restrictions from conception through the first two years of life lead to significant long-term health benefits. Researchers from the USC Dornsife College, McGill University, and UC Berkeley used data from the UK Biobank to study adults who experienced rationed sugar in early childhood during World War II. In the UK, sugar rationing began in 1942 and continued until 1953, meaning children conceived or born during this period grew up in an environment with limited sugar access .

By comparing health outcomes for those born just before and just after the end of rationing, researchers could assess the impact of early sugar restriction. The findings showed that people exposed to lower sugar intake in their first 1,000 days, counting from concept.
