Childhood sugary drinks linked to adult hypertension in 25-year study

A long-term study has uncovered a connection between childhood consumption of fructose-rich drinks and adult hypertension. Researchers from the University of Toronto and Harvard University led the investigation, which tracked over 25,000 participants for nearly 25 years. Their findings highlight how early dietary habits may influence later health risks. The study used data from the Growing Up Today Study (GUTS) cohort to examine dietary patterns and health outcomes. It found that sugar-sweetened beverages, including sports drinks, raised hypertension risk in a dose-dependent way—the more consumed, the higher the risk. Fruit juice showed mixed effects: moderate intake sometimes offered cardiovascular benefits, but excessive consumption still increased hypertension risk.

Whole fruit consumption, however, showed no link to higher hypertension risk. The research also revealed that replacing sugar-sweetened drinks or fruit juice with whole fruits, milk, or water reduced the likelihood of developing hypertension. The team stressed that dietary advice should prioritise whole foods over isolated nutrients like fructose. Hypertension remains a leading cause of cardiovascular disease and death worldwide. The study suggests that cutting back on fructose-rich drinks in childhood could lower adult hypertension risk. It also reinforces the benefits of choosing whole foods and healthier beverages early in life.
