Frequently Asked Questions (FAQ)
How many calories are in a radish?
A single medium radish weighing about 4.5 grams contains approximately 1 calorie. Even a generous serving of 10 radishes only adds about 7 calories, making radishes one of the lowest-calorie whole foods available.
Are radishes good for weight loss?
Radishes are an excellent food for weight loss due to their extremely low calorie density. At only 16 calories per 100 grams, they are mostly water and fiber. Their crunchy texture also provides satisfying volume and can be used as a low-calorie substitute for crackers or chips when eaten with dips.
Are radishes a good source of vitamin C?
Radishes provide a decent amount of vitamin C relative to their calorie content. A cup of sliced radishes delivers about 17 mg of vitamin C, which is roughly 19% of the daily recommended intake. While not as rich in vitamin C as citrus fruits, radishes contribute meaningful amounts as part of a varied diet.
Can you eat radish greens?
Yes, radish greens are edible and highly nutritious. They contain significantly more vitamin C, calcium, and iron than the radish root itself. Radish greens can be sauteed, added to soups, blended into pesto, or eaten raw in salads. They have a slightly peppery flavor similar to arugula.
What gives radishes their spicy flavor?
The peppery, slightly spicy taste of radishes comes from naturally occurring compounds called isothiocyanates, which are produced when the vegetable's cells are broken during biting or cutting. These same compounds have been studied for their potential anti-cancer properties. The spiciness tends to mellow when radishes are cooked or roasted.
