It is naturally low in calories while providing vitamin C, fiber, antioxidants, and plant compounds that support overall health.

This guide explores the nutrition, science-backed health benefits, possible side effects, best ways to eat radish, storage tips, precautions, and more.

What is Radish?

Radish (Raphanus sativus) is a root vegetable that belongs to the Brassicaceae (cruciferous) family, the same family as cabbage, broccoli, cauliflower, kale, and mustard greens. It is grown worldwide and comes in various colors, including white, red, pink, purple, black, and green.

The edible parts include both the crunchy root and the nutrient-rich green leaves. Radishes are commonly eaten raw but can also be cooked in soups, stir-fries, curries, roasted dishes, and pickles.

Because radish contains antioxidants, fiber, vitamins, minerals, and naturally occurring sulfur compounds called glucosinolates, it has long been valued in traditional diets as well as modern nutrition.
