What you eat before age 2 may affect your health 70 years later
A study using data from British sugar rationing after World War II suggests that low sugar consumption during the first 1,000 days of life is linked to lower cancer risk and slower biological aging in adulthood. The research highlights the long-term impact of early childhood nutrition on lifelong health.
Why it matters
Understanding the link between early-life diet and adult health outcomes can inform public health policies and dietary guidelines for infants.
Could how much sugar you consumed before your second birthday shape your health decades later - even into your 70s?
A new study that my colleagues and I conducted suggests the answer could be yes. People who had less sugar exposure during the first few years of life were much less likely to develop several different cancers later in life, and they also showed signs of slower biological ageing. We also found that even in adulthood, they continued to consume less sugar and had healthier diets overall.
This is not an easy question to study in real life. Researchers obviously can't run that experiment on real babies - split them into groups, feed one group sugar, then wait 70 years to see what happens.
