Frequently Asked Questions
What are the main nutritional benefits of eating green beans?
Green beans are rich in vitamins K, C, and A, folate, fiber, and minerals like potassium and iron. They're low in calories but high in nutrients, making them an excellent addition to a healthy diet. The combination of fiber and nutrients supports overall health while helping maintain healthy weight.
