Bok choy is a low-sugar leafy green, but its sugar content varies by serving size and preparation. Whether you're tracking carbs for a keto diet, managing blood sugar, or simply curious about your vegetable intake, this calculator gives you a quick, accurate estimate of the total sugar in bok choy based on the amount you plan to eat.
Simply enter the weight of raw or cooked bok choy, select the unit (grams or ounces), and optionally adjust for cooking method (raw vs. boiled). The tool accounts for standard USDA nutrition data and provides a breakdown of sugar per serving, plus a comparison to daily recommended limits. Perfect for meal planners, diabetics, and anyone following a low-sugar or whole-foods diet.

How to Use This Tool
Using the Bok Sugar Calculator is straightforward. Start by entering the amount of bok choy you plan to eat — either in grams or ounces. Then select whether the bok choy is raw or boiled (drained). Click "Calculate Sugar" to see the total sugar content, the sugar per 100 grams, and how that compares to the World Health Organization's recommended daily limit of 25 grams of added sugar. The tool uses standard USDA nutrition data for accuracy.
Tip: For meal prep, weigh bok choy before cooking. Boiling reduces sugar content slightly because some sugars leach into the water. If you're tracking net carbs, remember that bok choy's sugar is naturally occurring and comes with fiber, vitamins, and minerals.
Formula Explained
The calculation is based on the sugar density of bok choy per 100 grams. According to the USDA FoodData Central database, raw bok choy contains approximately 1.18 g of sugar per 100 g, while boiled bok choy (drained) contains about 0.80 g per 100 g. The formula is:
Total Sugar (g) = (Weight in grams / 100) × Sugar per 100g
For ounce inputs, the tool first converts to grams using the factor 1 oz = 28.3495 g. The result is then compared to the WHO's recommended maximum daily intake of 25 g of added sugar for adults. Note that this is a guideline for added sugars, not naturally occurring sugars in whole vegetables — but it provides a useful benchmark for overall sugar awareness.
Worked Examples
Example 1: You eat 150 g of raw bok choy in a stir-fry. Sugar = (150 / 100) × 1.18 = 1.77 g. That's just 7.1% of the 25 g daily limit.
Example 2: You have 4 oz (about 113 g) of boiled bok choy. First convert: 4 × 28.3495 = 113.4 g. Sugar = (113.4 / 100) × 0.80 = 0.91 g. That's only 3.6% of the daily limit.
Example 3: A large serving of 300 g raw bok choy yields 3.54 g sugar — still well under 15% of the daily limit, making bok choy an excellent low-sugar vegetable for any diet.
Tips & Best Practices
- Weigh bok choy raw for the most consistent tracking, as water loss during cooking can concentrate nutrients.
- If you're on a very low-carb or keto diet (under 20 g net carbs), bok choy is a great choice — its net carbs are roughly 1–2 g per 100 g after subtracting fiber.
- Pair bok choy with a source of fat (like sesame oil or avocado) to enhance absorption of fat-soluble vitamins A and K.
- For blood sugar management, the glycemic load of bok choy is negligible (under 1), so it won't spike glucose.
Frequently Asked Questions
Is bok choy high in sugar? No. Bok choy is very low in sugar — less than 1.2 g per 100 g raw, which is lower than many other vegetables like carrots or bell peppers.
Does cooking change the sugar content? Boiling can reduce sugar slightly because some sugars dissolve into the cooking water. Steaming or stir-frying without water will retain more sugar.
Can I use this for baby bok choy? Yes. Baby bok choy has a similar sugar profile; the difference is minimal. Use the same values.
How does bok choy compare to other greens? Bok choy has about the same sugar as spinach (0.4 g per 100 g) and less than kale (1.0 g per 100 g). It's one of the lowest-sugar leafy greens.
