Urban Farm DB summary
A 6-month study in northern Portugal evaluated the impact of three interventions on salt intake and blood pressure in 155 children aged 10-12. Interventions included a control, theoretical lessons on high salt intake, and theoretical lessons combined with practical school garden activities (planting, collecting herbs for salt substitution). Only the practical group showed a significant reduction in salt intake (1.1 g/day), with 50.9% of children reducing intake by at least 1g/day, suggesting that combined theoretical and practical education is more effective.
