The world has dozens of different types of radishes, each with its own unique look and flavor. As a whole, the group offers a lot of nutritional power in vitamins and particularly antioxidants. They include vitamin C, potassium, folate, vitamin B6, and more. The amount of minerals like calcium, magnesium, and iron is considerably higher for a vegetable, too. One cup has one gram of protein, and half of its carbohydrates come from fiber. Even though they grow underground, radishes are not related to carrots or potatoes very closely. Instead, they are cruciferous vegetables like cabbage. This gives them the same health benefits for fighting inflammation and helping to regulate H pylori in the gut. These delicious root vegetables also contain a compound that may help protect against cancer. [source]
