The consumption of healthy foods can lead to positive externalities by improving public health and lowering healthcare costs for everyone. When people eat nutritious meals, they are more likely to stay healthy, which means fewer visits to the doctor and less spending on medical treatments. This has a ripple effect, as a healthier population can contribute to a more productive workforce and reduced insurance costs for businesses. For example, if a community promotes the consumption of fruits and vegetables, it may see a decrease in obesity rates and related diseases. Overall, when individuals choose healthy foods, society benefits in many ways, including better health and lower healthcare expenses.
