Okra plant. Okra (also known as gumbo), is a tall-growing, warm-season, annual vegetable from the same family as hibiscus. The immature pods are used for soups, canning and stews or as a fried or boiled vegetable. Okra is a powerhouse of valuable nutrients. Nearly half of which is soluble fiber in the form of gums and pectins. Soluble fiber helps to lower serum cholesterol, reducing the risk of heart disease. Nearly 10% of the recommended levels of vitamin B6 and folic acid are also present in a half cup of cooked okra.
