Jicama is originally grown in Mexico, like the tomatillo. It's the root of the plant that is to be eaten, not the beans from it. It has a taste and texture that would be similar to a cross between a potato and a pear. People who are trying stabilize and regulate their blood sugar would really benefit from eating this root vegetable, since it's a prebiotic (can induce the production of good bacteria). It's a good source of fiber (which makes it helpful for treating and preventing constipation), a great source of Vitamin C, calcium, and potassium, and it's a potent antioxidant. You can cook it with some of your favorite dishes, chop them up/season to eat them as a replacement for french fries, or simply eat it fresh as a snack.
