Moreover, its fiber content aids in decreasing the risk of cardiovascular diseases by promoting healthier cholesterol levels.
Weight Management
Jicama is low in calories and high in water content, making it an excellent choice for weight management. The high fiber content keeps you fuller for longer periods, reducing the likelihood of overeating. Its low-calorie profile allows for a satisfying and nutritious addition to any diet without contributing to excessive caloric intake.
Safety and Risks
When eating jicama, it is important to know which parts are safe to consume and be aware of potential toxicity issues. Only the flesh is edible, and other parts of the plant carry risks. Here are the key points to consider.
Edible Parts of Jicama
Only the fleshy root portion of jicama is safe to eat. Its crunchy, juicy texture makes it popular in salads and snacks, often eaten raw or cooked.

Purchasing and Storage
Selecting quality jicama and storing it properly are crucial to ensure safety and maintain its nutritional benefits. This vegetable resembles a turnip and has a taste similar to water chestnuts.
Selecting Quality Jicama
When purchasing jicama, look for medium-sized, firm roots. The skin should appear smooth and free of blemishes or bruises. Avoid jicamas with soft spots, cracks, or shriveled areas, as these may indicate spoilage.
Check for a dry surface. Excess moisture can lead to quicker decay. A good-quality jicama will be heavy for its size, similar to how one might choose water chestnuts.
If buying pre-cut jicama, ensure it is fresh and lacks signs of drying out or discoloration. Fresh jicama has a crisp and juicy texture when cut open.
Storage Tips for Freshness
Refrigerate jicama to extend its shelf life. Whole jicamas can be stored in a cool, dry place, but it’s best to keep them refrigerated if you won't consume them within a week. Place the whole root in a plastic bag to keep it from drying out.
For cut jicama, pat the slices dry with a paper towel to remove any excess moisture. Store the pieces in an airtight container or a sealable freezer bag. This prevents the formation of ice crystals and maintains the crisp texture.
If you plan to freeze jicama, peel and slice it first. Blanch the slices in boiling water for a few minutes, then cool them in ice water. Dry thoroughly before storing in freezer bags. To ensure maximum freshness, place cut or diced jicama in the refrigerator's crisper compartment.
