Eggplant is a low-calorie, high-moisture vegetable that adds bulk and texture to meals without pushing your sugar count up. If you are tracking natural sugar for a low-sugar diet, keeping an eye on fruit and vegetable carbohydrates, or simply comparing ingredients for a healthier plate, this calculator gives you a clear answer in seconds. Raw eggplant contains roughly 3.53 g of sugar per 100 g, while boiled eggplant contains about 3.20 g per 100 g.
Use the fields below to enter your serving size, choose the unit and preparation state, and adjust the daily sugar budget if you want a personalized percentage. The calculator will estimate the total sugar, convert it to teaspoons, and show how much of a typical daily allowance that serving represents.
🍆 Eggplant Sugar Calculator
Find the natural sugar in a serving of eggplant — shown in grams, teaspoons, and as a share of your daily sugar budget.
How to Use This Tool
Start by entering the amount of eggplant you plan to eat in the first field. Choose the unit that matches how you measure it: grams, ounces, chopped cups, or whole medium eggplants. Next, select whether the eggplant is raw or cooked and boiled, because heat and water changes affect the sugar concentration. The daily sugar budget field is optional; if you leave it blank or keep the pre-filled 50 grams, the calculator will use 50 grams as a general reference point. Press Calculate sugar to see the total sugar in your serving, its equivalent in teaspoons, and the percentage of your daily budget.

How the Sugar Estimate Is Calculated
The calculator uses standard nutrition data for eggplant. Raw eggplant contains about 3.53 g of total sugars per 100 g, while boiled, drained eggplant contains about 3.20 g per 100 g. Once your serving is converted to grams, the math is simple:
For volume and whole-vegetable units, this tool applies approximate conversions: 1 cup of raw chopped eggplant weighs about 82 g; 1 cup of cooked diced eggplant weighs about 99 g; one medium raw eggplant provides about 300 g of edible flesh, or roughly 220 g after boiling and draining. These figures vary with variety, moisture, and how finely the eggplant is chopped, so treat them as helpful estimates rather than laboratory measurements.
Worked Examples
Example 1 — 150 g raw eggplant. A side portion of raw cubed eggplant weighing 150 g contains 150 × 3.53 ÷ 100 = 5.30 g of sugar. That is about 1.26 teaspoons, and it would use 10.6% of a 50 g daily sugar budget.
Example 2 — 2 cups cooked eggplant. Two cups of boiled eggplant weigh about 198 g. The sugar total is 198 × 3.20 ÷ 100 = 6.34 g, which is close to 1.51 teaspoons and about 12.7% of a 50 g budget.

Tips for Tracking Eggplant Sugar
- Weigh the part you actually cook. Trimming the stem and peeling can reduce the usable weight by 15–25%.
- Choose raw or boiled values depending on your recipe. Boiling leaches some sugar into the water; roasting can concentrate sugar because moisture evaporates.
- Account for cooking oil, breading, and sauces. They add calories and often sugar, even when the eggplant itself stays low.
- If you are comparing eggplant with other vegetables, use calculators like the onion sugar calculator or the nectarine sugar calculator to check whether another ingredient fits your daily target.
Frequently Asked Questions
Is eggplant considered a high-sugar vegetable? No. At about 3.5 g of sugar per 100 g, eggplant is low compared with many fruits and some vegetables such as onions. If you are comparing, the onion sugar calculator shows how a sweet vegetable compares, while the nectarine sugar calculator demonstrates typical fruit sugar levels.
Does cooking remove sugar from eggplant? Boiling can remove a small amount of sugar because some natural sugars dissolve into the cooking water. Roasting or grilling, by contrast, evaporates water and can make the remaining sugar more concentrated gram-for-gram. The practical difference is usually small for a single serving.
Should I count eggplant sugar on a keto or diabetic diet? Many people include eggplant on low-carb and diabetes-friendly eating plans because its total carbohydrate is moderate and its fiber content helps slow digestion. Still, serving size matters, and any added breading or sweet sauce can change the meal completely.
