Scientific explanation
Research-backedBrussels Sprouts provides approximately 43 kcal per 100g with 3.38g protein, 8.95g carbohydrates, and 0.3g fat. Dietary fiber is 3.8g per 100g, while total sugars stand at 2.2g. The glycemic index of Brussels Sprouts is estimated at 15 (low), meaning glucose rises at a slow, stable rate after consumption. These values are sourced from USDA FoodData Central and reviewed for editorial accuracy. Beyond basic macronutrients, Brussels Sprouts is an exceptional source of micronutrients, particularly Vitamin K (177 mcg per 100g, or 148% of the Daily Value) and Vitamin C (85 mg per 100g, or 94% of the Daily Value). Vitamin K is essential for blood coagulation and bone mineralization, while Vitamin C acts as a powerful antioxidant that supports immune function and collagen synthesis. Additionally, Brussels Sprouts contains 389 mg of potassium per 100g, which helps regulate fluid balance, nerve signals, and muscle contractions.

Community insights
Community insightAmong Victura meal logs, Brussels Sprouts appears frequently as a versatile side dish, meal-prep staple, and air-fried snack. Users pairing it with healthy fats—such as olive oil, avocado oil, or a sprinkle of parmesan cheese—report significantly higher satisfaction and steadier energy levels than eating it steamed or plain. This culinary practice is scientifically sound, as the fat-soluble vitamins in Brussels Sprouts, particularly Vitamin K, require dietary lipids for optimal absorption in the digestive tract. Many users also note that roasting Brussels Sprouts at high temperatures reduces the bitter compounds (glucosinolates) by caramelizing the natural sugars, making them highly palatable even for those who typically avoid cruciferous vegetables.
