Whether you’re meal prepping, tracking macros, or simply curious about the nutritional profile of your favorite sprouts, this calculator gives you a precise estimate of calories per slice (or per serving) based on the type of sprout and slice thickness. Sprouts like broccoli, alfalfa, mung bean, and radish vary in water content and density, which directly affects calorie density.
Simply select the sprout variety, enter the number of slices (or a weight in grams), and choose a slice thickness. The tool instantly computes total calories, calories per slice, and a macronutrient breakdown (carbs, protein, fat). Perfect for diet planning, healthy eating, and anyone following a calorie-controlled lifestyle.
🥦 Sprout Calories Per Slice
How to Use This Tool
Select your sprout type from the dropdown (broccoli, alfalfa, mung bean, radish, or clover). Enter the number of slices you plan to eat, and choose a slice thickness — thin (1 mm), medium (3 mm), or thick (5 mm). If you know the exact weight of your sprouts in grams, you can enter that instead for a more accurate calculation. Click "Calculate" to see total calories, calories per slice, and a macronutrient breakdown (carbs, protein, fat). Use the reset button to clear results and start over.
How It Works
The calculator uses average calorie densities for each sprout type, derived from USDA food composition data. For example, broccoli sprouts contain about 0.35 kcal per gram, while alfalfa sprouts are around 0.23 kcal/g. Slice thickness affects the weight per slice: a thin slice is about 70% of the medium slice weight, and a thick slice is about 140%. The tool multiplies the number of slices by the weight per slice to estimate total weight, then multiplies by the calorie density to get total calories. Macronutrients are estimated using typical sprout ratios: 50% of calories from carbs, 30% from protein, and 20% from fat.
Worked Examples
Example 1: 5 slices of medium-thick broccoli sprouts. Weight per slice = 2.5 g × 1.0 = 2.5 g. Total weight = 12.5 g. Total calories = 12.5 × 0.35 = 4.4 kcal. Calories per slice = 0.9 kcal.
Example 2: 10 slices of thin alfalfa sprouts. Weight per slice = 1.8 g × 0.7 = 1.26 g. Total weight = 12.6 g. Total calories = 12.6 × 0.23 = 2.9 kcal. Calories per slice = 0.3 kcal.
Example 3: 50 g of mung bean sprouts (weight entered directly). Total calories = 50 × 0.30 = 15.0 kcal. Carbs = 15 × 0.5 / 4 = 1.9 g, protein = 15 × 0.3 / 4 = 1.1 g, fat = 15 × 0.2 / 9 = 0.3 g.
Tips for Accurate Tracking
For best results, weigh your sprouts on a kitchen scale rather than relying on slice count — sprout density can vary. If you're meal prepping, consider that sprouts lose water when cooked, which concentrates calories slightly. Always use the same slice thickness for consistency. This tool is ideal for anyone tracking calories for weight management, athletes monitoring macros, or individuals on low-calorie diets.
Frequently Asked Questions
Are sprout calories the same for all types? No, different sprouts have different water and nutrient content. Broccoli sprouts are more calorie-dense than alfalfa, for example.
Can I use this for cooked sprouts? The calculator is based on raw sprout data. Cooking can reduce water content, so calories per gram may increase slightly. For cooked sprouts, consider using a weight-based entry and adjust density if needed.
How accurate is the macronutrient breakdown? The breakdown is an estimate based on typical sprout profiles. For precise macros, refer to the USDA FoodData Central database.
What if I eat a whole bag of sprouts? Enter the total weight from the package label for the most accurate result.
