A low-sugar diet in utero and in the first two years of life can meaningfully reduce the risk of chronic diseases in adulthood, a new study has found, providing compelling new evidence of the lifelong health effects of early-life sugar consumption. Published in Science , the study finds that children who experienced sugar restrictions during their first 1,000 days after conception had up to 35% lower risk of developing type 2 diabetes and as much as 20% less risk of hypertension as adults. Low sugar intake by the mother prior to birth was enough to lower risks, but continued sugar restriction after birth increased the benefits.
Taking advantage of an unintended "natural experiment" from World War II, researchers at the USC Dornsife College of Letters, Arts and Sciences, McGill University in Montreal, and the University of California, Berkeley, examined how sugar rationing during the war influenced long-term health outcomes. The United Kingdom introduced limits on sugar distribution in 1942 as part of its wartime food rationing program. Rationing ended in September 1953.
The researchers used contemporary data from the U.K. Biobank, a database of medical histories and genetic, lifestyle and other disease risk factors, to study the effect of those early-life sugar restrictions on health outcomes of adults conceived in the U.
K. just before and after the end of wartime sugar rationing. "Studying the long-term effects of added sugar on health is challenging," says study correspondi.
