Fresh green beans are very low in calories (31 calories per 100 g of raw bean pods) and contain no saturated fat. Nevertheless, these lean
pod vegetables are a very good source of vitamins, minerals, and plant-derived micronutrients. Green beans contain excellent levels of vitamin A, and health-promoting flavonoid polyphenolic antioxidants such as lutein, zeaxanthin and ß-carotene in good amounts. These compounds help act as protective scavengers against oxygen-derived free radicals and reactive oxygen species (ROS) that play a role in aging and various disease processes.
