How Many Calories Are in a Green Onion? Unveiling the Nutritional Profile
A single green onion, also known as a scallion, contains a negligible amount of calories. Typically, one medium green onion, including both the white bulb and green stalks, contains approximately 5 calories, making them a fantastic, low-calorie addition to any meal.
Understanding Green Onions and Their Nutritional Value
Green onions, or scallions, are young onions harvested before the bulb fully develops. They are characterized by their mild onion flavor and versatility in culinary applications. While low in calories, they offer a surprising range of health benefits and contribute to a balanced diet.
The Calorie Count: Breakdown by Portion
While the overall calorie count for a single green onion is low, it’s helpful to understand the approximate calorie contribution from different parts of the plant.
- White Bulb: The bulb portion contains slightly more calories per gram compared to the green stalks, but the difference is minimal.
- Green Stalks: The green stalks are mostly water and fiber, resulting in a very low calorie count.
A common serving size for chopped green onions is about 1/4 cup, which would still only contain around 2-3 calories. This underscores their minimal caloric impact on a meal.
Nutritional Benefits Beyond Calories
Green onions are more than just a low-calorie ingredient. They are packed with essential vitamins and minerals that contribute to overall health.
- Vitamin K: Important for blood clotting and bone health.
