String beans: Also known as green beans are high in fibre, vitamins and minerals. the good part is that they are low in carbohydrates. They contain protein, calcium, dietary fibre, Omega-3 fats and iron. The carotenoid and flavonoid content of the bean has anti-inflammatory properties.
The high Vitamin K helps the bones to take in calcium. It also regulates bone metabolism and prevents the loss of minerals. One cup of boiled string beans contains 20 mg of Vitamin K. The Vitamin C neutralises the free radicals before they can cause damage to the healthy cells. Vitamin C also protects proteins, carbohydrates and DNA from free radicals. People who want to lose weight can eat them in good amounts.
The beans are rich in carotenoids, which can prevent a decrease in vision and eye function. Including a healthy portion of green beans in the diet can also ensure that Lutein and Zeaxanthin present in them prevent any stress to the inner workings of the eye. Green beans have very few risk-factors but the phytic acid present in them can bind the important minerals like calcium and zinc and does not allow them to be absorbed by the body. If one suffers from conditions that cause a mineral deficiency, intaking beans in large quantities is a no-no.
