As a very good source of fiber, the fennel bulb may help to reduce elevated cholesterol levels. In addition to its fiber, fennel is a very good source of folate and potassium, which helps lower high blood pressure. The vitamin C found in the fennel bulb is the body’s primary water soluble antioxidant and needed for the proper function of the immune system. Fennel is composed of a white or pale green bulb from which closely superimposed stalks are arranged. The stalks are topped with feathery green leaves near which flowers grow and produce fennel seeds.
Look for fennel with bulbs that are clean, firm and solid, without signs of splitting, bruising, or spotting. The bulbs should be whitish or pale green in color. Store fennel in the refrigerator crisper.
