Radishes are a very good source of vitamin C – 25% of the daily recommended value – helping to rebuild tissues and blood vessels, and keeping bones and teeth strong. Vitamin C fights disease and rescues the cells from an onslaught of destructive free radicals. This is done through electrolytes and natural antioxidant action of this one vitamin, increasing immunity of the body, and helping to fight against all kinds of diseases, including cancer, heart disease, and stroke.
Folate, fiber, riboflavin, and potassium, as well as good amounts of copper, vitamin B6, magnesium, manganese, and calcium are less prominent nutrients that support the healthy properties of radishes.
It's probably no surprise that radishes contain fiber, aka indigestible carbohydrates. This keeps your system flushed and functioning with regularity and also aids in maintaining a healthy weight. Ironically, these naturally-heated veggies may help put an end to any burning sensation experienced during urination. That may be because radishes are a natural diuretic, purifying the kidney and urinary systems and relieving inflammation.
Radishes can also regulate blood pressure, relieve congestion, and prevent respiratory problems such as asthma or bronchitis. They have antibacterial, antifungal, and detoxifying properties, and contain compounds that soothe rashes, dryness, and other skin disorders.
Eating radishes can help in the removal of bilirubin, a condition evidenced by a yellow tinge in the skin, mucus membranes, or eyes, often present in newborns. This type of jaundice occurs when bilirubin builds up in bile faster than the liver can break it down and pass it through your body. Meanwhile, the beneficial properties in radishes also inhibit red blood cell damage by supplying fresh oxygen to your blood.
Another mouthful of phytochemical goodness in radishes includes detoxifying agents called indoles, and the powerful flavonoids zeaxanthin, lutein, and beta carotene. Radishes also contain an important isothiocyanate antioxidant compound called sulforaphane, a proven inhibitor of prostate, colon, breast, ovarian and other cancers.
