Jicama's Low Sugar Profile
Jicama is a low-sugar root vegetable, making it a fantastic addition to a healthy diet. A standard one-cup serving (approximately 130 grams) contains only about 2.3 to 2.34 grams of total sugar. What is perhaps more important is the ratio of sugar to fiber. Jicama contains a generous 6.4 grams of dietary fiber per cup, which significantly impacts how the body processes the small amount of sugar present. This high fiber content, particularly the prebiotic fiber inulin, slows down the digestion and absorption of carbohydrates, preventing the sharp blood sugar spikes typically associated with sugary foods. For individuals monitoring their blood glucose, such as those with diabetes, this makes jicama a much safer and more beneficial choice than other starchy vegetables.
The Impact of Fiber and Glycemic Index
The glycemic index (GI) measures how quickly a food raises blood sugar levels. Jicama's low sugar and high fiber content give it a very low GI of just 17. This low score means it has a minimal impact on blood glucose, offering a gradual and steady release of energy. In contrast, high-GI foods cause rapid blood sugar fluctuations. The prebiotic fiber, inulin, not only aids in blood sugar control but also supports a healthy gut microbiome, which further contributes to overall metabolic health.
A Complete Nutritional Breakdown
Beyond its low sugar content, jicama offers an impressive array of nutrients for very few calories. It is over 85% water, providing excellent hydration, and is an outstanding source of Vitamin C, with a single cup supplying over a third of the recommended daily intake. It also contains essential minerals that support various bodily functions.

Jicama vs. Other Common Vegetables
To put its nutritional value into perspective, especially its sugar and carbohydrate content, here is a comparison of jicama with other popular vegetables, all based on a one-cup serving:
| Vegetable | Calories | Total Carbs (g) | Fiber (g) | Sugar (g) |
|---|---|---|---|---|
| Jicama | 49 | 12 | 6.4 | 2.3 |

This comparison highlights how jicama stands out as a low-calorie, low-sugar option, particularly when compared to other starchy root vegetables like potatoes and sweet potatoes. While carrots and turnips have similar calorie and carb counts, jicama offers a superior fiber-to-sugar ratio.
Health Benefits of Jicama's Low Sugar and High Fiber
The unique nutritional profile of jicama offers numerous health advantages, including:
- Supports Digestive Health: The high fiber content, especially the prebiotic fiber inulin, promotes a healthy gut environment by feeding beneficial gut bacteria. It also adds bulk to stool, helping to prevent constipation and promote regularity.
- Aids in Weight Management: As a low-calorie and low-sugar food that is high in fiber and water, jicama helps you feel full and satiated for longer. This can reduce overall calorie intake and assist in weight loss efforts.
- Boosts Heart Health: The fiber in jicama can help lower cholesterol levels, and its potassium content helps regulate blood pressure. Both are key factors in reducing the risk of cardiovascular disease.
- Enhances Immune Function: Jicama is rich in vitamin C, a powerful antioxidant that helps protect cells from damage caused by free radicals. This boosts the immune system and reduces inflammation throughout the body.
- Regulates Blood Sugar: Due to its low glycemic index and high fiber content, jicama is an excellent choice for individuals with diabetes or those looking to prevent blood sugar spikes.
How to Incorporate Jicama Into Your Diet
Jicama is incredibly versatile and can be enjoyed in many ways, both raw and cooked. Here are a few easy ideas to get you started:

- Salads and Slaws: Shred or julienne raw jicama and add it to salads or make a crunchy, refreshing slaw.
- Stir-Fries: Cube or slice jicama and toss it into a stir-fry. It retains its crisp texture even when cooked, similar to a water chestnut.

- Appetizers: Serve jicama slices or sticks with a healthy dip like guacamole or hummus.
- Fruit Salad: Dice jicama and mix it with fruits like mango, pineapple, and oranges for added crunch and texture.
Conclusion
In summary, jicama is a nutritious and versatile root vegetable with a very low sugar content, providing approximately 2.3 grams per cup.

Its low glycemic index and rich vitamin and mineral content further cement its status as a highly beneficial food for overall health. Whether eaten raw as a crunchy snack or cooked into a meal, jicama is an excellent low-sugar and high-fiber alternative to consider for a healthier diet.
