An apple a day: the impact of healthier school meals on children in Jordan

Poor nutritional choices and unhealthy behaviors are considered responsible for the rise in childhood overweight and obesity and may reinforce each other, creating a vicious cycle. This paper studies a primary school intervention designed to break the cycle early in life by replacing date bars with calorie-equivalent meals lower in sugar and fat. Leveraging the randomized pilot of a menu change in Jordan’s national school feeding program, the study shows that children consuming the alternative meals spend 8 percent less money to buy processed snacks, are more physically active (0.1 standard deviation), and go to school one extra day per year.
