What is Jicama?
Jicama (pronounced HEE-kah-mah) is a crunchy root vegetable commonly used in Mexican cuisine. Jicama also goes by the names yam bean, Mexican turnip, and Mexican potato.
Jicama is a member of the Fabaceae (a bean family that counts "peas" as its main member). It grows on a vine up to 20 feet tall, however the only edible part of the plant is the bulbous root underground. Don’t consume the leaves, seeds, or flowers of the plant. The edible root can be as small as a Gala apple or grow as big as two fists put together. Harvested for centuries in Mexico and other all year round hot areas in South America, nowadays jicama is also grown in parts of southeast Asia. Traditionally, street vendors in Mexico sell peeled and sliced strips of raw jicama with lemon or lime juice and chili powder.
Taste and Texture
Unlike other root vegetables, jicama's tuberous root is "not" that starchy; although it tastes somewhat sweet, it is quite low in sugar, making it a perfect low-carb choice for people leading a ketogenic diet. Raw jicama root inside looks like a potato, is crispy, has a pleasant crunch and a refreshing juiciness to it, similar to a fresh water chestnut or a firm Asian pears (aka shinseiki).
Jicama picks up flavors well due to its porous flesh. It can be marinated with citrus juice and the spices and chunks can be added to salads. It can be sliced thinly and added to a sandwich for some crunch; it can also be used in lieu of a corn tortilla for tacos. Cooking jicama proves tasty too, though it needs a gentle touch when it comes to heat.
Storage
It is best to keep jicama whole and unpeeled in the refrigerator for up to two weeks, or for about a week on your counter as long as it's not in sunlight or the kitchen gets too hot. Once peeled, you can slice the vegetable and keep it in water in the refrigerator for a few days. Cover any exposed areas with plastic wrap to minimize air exposure.
It's best to eat it fresh, soon after peeling and cutting.

Jicama Health Benefits
The most significant advantages of including jicama in your diet come from its high fiber content and its concentration of vitamin C.
Jicama has a low glycemic index. This means that eating jicama may help to prevent spikes in blood sugar levels, which may make it a good choice for people with diabetes.
Fiber supports digestion and regularity, lowers the risk of some types of cancer, obesity, cardiovascular disease, and diabetes.
Low in calories but with plenty of vital nutrients, jicama is high in a fiber known as oligofructose inulin (with its zero calories). Inulin promotes good bone health by enhancing absorption of calcium from other foods, protecting against osteoporosis.
Inulin acts as a probiotic role in the intestine, promoting good bacteria growth to maintain both a healthy colon and balanced immunity.
The prebiotic, fermentable fiber in jicama contributes to a healthy gut microbiome, the colony of "good" bacteria in the digestive tract.
Vitamin C is an antioxidant, and regenerates other antioxidants within the body, including vitamin E.
Antioxidants may help to prevent or delay the development of certain cancers and cardiovascular disease.
