Is Singkamas Good for a Low-Carb Diet? The Nutritional Breakdown
Singkamas, known globally as jicama, is a versatile root vegetable popular in Filipino cuisine and Mexican dishes alike. Its reputation for being a low-carb alternative is well-founded, but what exactly does its nutritional profile look like? Understanding the difference between total carbohydrates and net carbohydrates is key to answering the question, "Is singkamas good for a low-carb diet?" Net carbs are calculated by subtracting fiber from the total carbohydrate count. Because singkamas is exceptionally high in dietary fiber, its net carb count is significantly lower than that of other starchy root vegetables like potatoes.
According to nutritional data, a 100-gram serving of raw singkamas typically contains around 8.8 grams of total carbohydrates but almost 5 grams of that comes from fiber. This leaves a net carb count of just under 4 grams. This makes it a fantastic addition to low-carb meal plans, including ketogenic diets, where counting net carbs is a common practice. The high fiber content not only reduces the carb impact but also contributes to several health benefits, making singkamas a nutrient-dense choice.
The Health Benefits of Adding Singkamas to Your Diet
Beyond its low-carb profile, singkamas offers numerous health advantages that make it a valuable dietary component. These benefits are driven by its rich fiber, vitamin, and antioxidant content.
- Promotes Digestive Health: The high fiber content in singkamas helps regulate bowel movements and can prevent constipation. The vegetable is also a rich source of inulin, a type of prebiotic fiber that feeds beneficial gut bacteria, promoting a healthy digestive system.
- Aids in Weight Management: As a low-calorie, high-fiber, and high-water food, singkamas helps increase feelings of fullness and satiety, which can help reduce overall calorie intake and support weight loss goals.
- Supports Heart Health: Singkamas contains dietary fiber, potassium, and antioxidants, which can help lower cholesterol levels, reduce blood pressure, and improve circulation, all of which are beneficial for heart health.
- Boosts Immune Function: A single cup of jicama provides a substantial amount of Vitamin C, a powerful antioxidant that helps protect against cell damage and bolsters the immune system.
- Regulates Blood Sugar: The combination of fiber and low sugar content gives singkamas a low glycemic index, meaning it causes a slower, more gradual release of sugar into the bloodstream. This makes it a suitable option for individuals managing blood sugar levels, such as those with diabetes.
Culinary Versatility: How to Enjoy Singkamas on a Low-Carb Diet
The mildly sweet, juicy, and crunchy texture of singkamas makes it a fantastic culinary ingredient. It can be enjoyed raw or cooked, and its ability to maintain its crispness even when cooked makes it a great substitute for high-carb ingredients.
Here are a few low-carb ways to incorporate singkamas into your meals:
- Crunchy Strips: Slice peeled singkamas into long, thin strips and sprinkle with lime juice, chili powder, and salt for a refreshing, spicy snack, much like the popular Mexican street food.
- Low-Carb "Rice": Grate singkamas to create a rice-like texture, then squeeze out excess moisture and sauté it for a few minutes. This serves as an excellent low-carb alternative to traditional rice.
- Salads and Slaws: Add shredded or cubed singkamas to salads and slaws for extra crunch and a hint of sweetness.
- Stir-Fries and Soups: Include singkamas in stir-fries or soups, where it adds a pleasant, water-chestnut-like texture without the starch.
- Low-Carb "Fries": Cut singkamas into fry-like shapes, season with spices, and bake or air-fry until tender-crisp for a healthier version of French fries.
Singkamas vs. Other Vegetables: A Nutritional Comparison
To put singkamas' low-carb benefits into perspective, let's compare its nutritional values to other common vegetables, highlighting the differences in total carbs and fiber.
| Vegetable | Total Carbs (per 100g) | Dietary Fiber (per 100g) | Net Carbs (per 100g) | Suitability for Low-Carb Diet |
|---|---|---|---|---|
| Singkamas (Jicama) | ~8.8g | ~4.9g | ~3.9g | Excellent |
| Potato | ~17.5g | ~2.2g | ~15.3g | Poor |
| Sweet Potato | ~20.1g | ~3.0g | ~17.1g | Poor |
| Cauliflower | ~5.0g | ~2.0g | ~3.0g | Excellent |
| Broccoli | ~6.6g | ~2.6g | ~4.0g | Excellent |
This comparison clearly illustrates that singkamas holds its own among the best low-carb vegetable options. Its high fiber content gives it a similar net carb count to cauliflower and broccoli, while being a much lower-carb choice than traditional starchy roots like potatoes.
Important Safety Note
When preparing singkamas, it is crucial to remember that only the root vegetable is safe for consumption. The rest of the plant, including the leaves, beans, and flowers, contains a natural insecticide called rotenone, which is toxic to humans. Always peel the brown, papery skin before eating and never consume any other part of the plant.

With its combination of high fiber, low net carbs, and a variety of health benefits, singkamas proves to be a valuable addition to any low-carb or keto eating plan. Its crunchy texture and mild, sweet flavor make it a versatile ingredient for snacks, salads, and cooked dishes, offering a healthy and satisfying alternative to high-starch vegetables.
