- 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 an excellent source of vitamins, minerals, and plant derived micronutrients.
- The beans are a very rich source of dietary fiber (9% per 100g RDA) which acts as a bulk laxative. Fiber helps to protect colon mucosa by decreasing its exposure time to toxic substances as well as by binding to cancer-causing chemicals in the gut. An adequate amount of fiber in the diet has also been shown to reduce blood cholesterol levels by decreasing reabsorption of cholesterol-binding bile acids in the colon.
- Green beans contain excellent levels of vitamin-A, and health promoting flavonoid poly phenolic antioxidants such as lutein, zeaxanthin, and β -carotene in right 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.
