New research indicates that the period of sugar rationing in the UK following the Second World War may have had long-term health benefits for those born during that time. Scientists are now examining the health of individuals who spent their first 1,000 days of life under these restrictions, suggesting a lasting impact more than seven decades later.
Dr. Tadeja Gračner and colleagues, using UK Biobank data, found that the longer people were exposed to rationing, the lower their risk of developing type 2 diabetes and high blood pressure in mid- to later life. Those exposed throughout their first 1,000 days had a 35% lower risk of type 2 diabetes and a 20% lower risk of high blood pressure compared to those who never experienced rationing.
Further studies, including work by Dr. Jiazhen Zheng, have linked reduced early sugar exposure to lower risks of cardiovascular disease, liver disease, respiratory health, dementia, and improved measures of ageing. Additionally, Professor Nophar Geifman and her team reported a 33% lower risk of anxiety diagnosis for those who experienced the full first 1,000 days under sugar rationing.
The exact mechanisms behind these long-term effects remain uncertain. Researchers are exploring whether the impact is through sugar itself, early-formed taste preferences, or metabolic responses set in early life. One hypothesis suggests that growing up under rationing may weaken the influence of genes predisposing individuals to higher body weight.
