Folic acid, also known as folate, is one of the B vitamins. Technically, folate is the natural form of B9 that occurs in food, while folic acid is the synthetic form used to enrich foods. It is important to have enough folic acid in your diet to counter heart disease, depression, age-related hearing loss, certain cancers and certain birth defects. Vitamins in the B family are water soluble and cannot be stored by the body. You need to eat enough foods rich in folate or folic acid every day to meet your body's needs. The amount of folic acid you need daily varies from 180 to 200 micrograms for most adults to 400 micrograms for women of childbearing age, according to nutritionists at Colorado State University.
Asparagus
One cup of asparagus contains between 170 and 240 micrograms of folic acid.
Black Beans
