Green Beans / 1 kg

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.

Zea-xanthin, an important dietary carotenoid in the beans, selectively absorbed into the retinal macula lutea in the eyes where it thought to provide antioxidant and protective UV-light filtering functions. It is, therefore, green beans offer some protection in the prevention ofage-related macular disease (ARMD) in the older adults.

Snap beans are an excellent source of folates. 100 g fresh beans provide 37µg or 9% of folates. Folate along with vitamin B-12 is one of the essential components of DNA synthesis and cell division. A good folate diet, when given during preconception periods and pregnancy, may help prevent neural-tube defects in the newborn babies.

They also carry good amounts of vitamin-B6 (pyridoxine), thiamin (vitamin B-1), and vitamin-C. Consumption of foods rich in vitamin-C helps the body develop resistance against infectious agents and scavenge harmful oxygen-free radicals.

Moreover, they contain healthy amounts of minerals like iron, calcium, magnesium, manganese, and potassium, which very essential for body metabolism. Manganese is a co-factor for the antioxidant enzyme, superoxide dismutase, which is a very potent free radical scavenger. Potassium is an important component of cell and body fluids that helps controlling heart rate and blood pressure.
