Jicama

Also indexed as: Mexican Potato

Jicama is great in salads, or cut in cubes and served with a squeeze of lime juice or a dusting of chili powder.

Sometimes called Mexican potato, this root vegetable has a mildly sweet, elusive flavor, and a crisp, moist texture. It looks something like a cross between a potato and a turnip, with a thin brown skin, a round, turnip-like form and tail, and smooth white flesh.

Varieties

Jicama varies somewhat in size.

Buying and storing tips

Jicama can be found in the produce section of most health food stores, specialty markets, and supermarkets. Look for heavy, dense roots and smooth skin. Store it in a cool, dry place; too much moisture will cause mold.

Availability

Jicama is available from November through May.

Preparation, uses, and tips

Wash and peel just before using, as the flesh darkens when exposed to air. Add sliced or grated jicama to salads, or cut it in cubes and serve it with a squeeze of lime juice and a dusting of chili powder. It’s a good substitute for water chestnuts in stir-fry dishes.

Health benefits and concerns

Asthma

Vitamin C, present in fruits and vegetables, is a powerful antioxidant and anti-inflammatory. This anti-inflammatory activity may influence the development of asthma symptoms. A large preliminary study has shown that young children with asthma experience significantly less wheezing if they eat a diet high in fruits rich in vitamin C.

Bruising

Many Americans eat insufficient amounts of foods containing vitamin C; the disease caused by vitamin C deficiency, scurvy, causes easy bruising. While very few people actually have scurvy, even minor deficiencies of vitamin C can increase the incidence of bruising. People who experience easy bruising may want to try eating more fruits and vegetables—common dietary sources of vitamin C.

Capillary fragility

Eating plenty of flavonoid- and vitamin C-rich fruits and vegetables helps to support the structure of capillaries.

High homocysteine

A controlled trial showed that eating a diet high in fruits and vegetables containing folic acid, beta-carotene, and vitamin C effectively lowered homocysteine levels. Healthy people were assigned to either a diet containing a pound of fruits and vegetables per day, or to a diet containing 3 1/2 ounces (99g) of fruits and vegetables per day. After four weeks, those eating the higher amount of fruits and vegetables had an 11 percent lower homocysteine level compared to those eating the lower amount of fruits and vegetables.

Multiple sclerosis (MS)

In one survey, researchers gathered information from nearly 400 people (half with MS) over three years. They found that consumption of vegetable protein, fruit juice, and foods rich in vitamin C, thiamine, riboflavin, calcium, and potassium correlated with a decreased MS risk.
