Jicama, also known as Mexican yam bean or Mexican turnip, has gained popularity in recent years due to its crisp texture and mild, slightly sweet taste.
But for people managing blood sugar levels, especially those with diabetes or prediabetes, the most pressing question is: Does jicama raise blood sugar?
In this article, we’ll talk about what’s in jicama, how it affects blood sugar, and why it might actually help keep blood sugar steady. We’ll also check out some studies and expert opinions to give you the full picture.
What Is Jicama?
Jicama is a root vegetable native to Mexico and Central America. It has a thin brown skin and white, juicy flesh. Unlike many starchy vegetables, jicama is low in calories and carbohydrates. It is commonly eaten raw in salads, used in stir-fries, or enjoyed as a snack with lime and chili powder.
This tuber belongs to the legume family but is unique because only the root is edible; the rest of the plant, including the seeds, is toxic.

Does Jicama Raise Blood Sugar?
The short answer is no, jicama does not significantly raise blood sugar levels in most individuals. In fact, its nutritional composition may help stabilize blood glucose due to its high fiber content, particularly inulin, a type of prebiotic fiber.
Inulin slows the digestion of carbohydrates and improves insulin sensitivity, which can contribute to better glycemic control. According to a study published in the British Journal of Nutrition, inulin supplementation was linked to reduced fasting blood sugar levels in individuals with type 2 diabetes.
Furthermore, jicama has a low glycemic index (GI), which means it causes a slow and gradual increase in blood sugar rather than a spike. Low-GI foods are recommended for individuals managing diabetes or insulin resistance.
So, does jicama raise blood sugar? Not likely, and it may even support better glucose regulation when included as part of a balanced diet.

Why Jicama Is a Smart Carb Choice
According to Food Research, 2020, here are several reasons why jicama can be a smart choice for anyone watching their blood sugar:
1. High in Soluble Fiber
Soluble fiber, like inulin, helps slow the absorption of sugar in the bloodstream. This reduces insulin spikes and supports metabolic health.
2. Supports Gut Health
Inulin acts as a prebiotic, feeding the good bacteria in your gut. A healthier gut microbiome has been linked to improved insulin sensitivity, according to research published in the Journal of Diabetes Investigation.

3. Low in Net Carbs
Net carbs (total carbs minus fiber) are what count most for blood sugar impact. Jicama has about 5 grams of net carbs per cup, making it a low-carb option suitable even for ketogenic diets.
4. Rich in Antioxidants
Jicama is a good source of vitamin C, which plays a role in reducing oxidative stress, a factor that contributes to insulin resistance.
