Pickled radish is healthy as long as it is consumed in small portions. In terms of nutritional value, some experts will argue that pickling liquid is unhealthy, but it is fine in moderation. Radish on its own is full of good bacteria, calcium, vitamin C, fiber, and folates. These benefits are only increased by pickling.  In general, radishes are good for improving digestion, protecting against infections, and promoting beautiful skin and hair. They are a great low-calorie food that is high in nutritional value.
