About this food

Understanding this nutrition reference

Radishes are a crisp, peppery root vegetable with a bright red skin and white flesh. They are most often eaten raw, sliced into salads or served whole as a crunchy snack, though they can also be roasted or pickled. Their peppery bite comes from natural compounds that mellow when the radish is cooked.

Nutritionally, radishes are very low in calories and provide dietary fiber, vitamin C, and small amounts of minerals such as potassium. Because they add crunch and flavor for very few calories, they are a popular choice in calorie-conscious and vegetable-forward eating plans.
