HEALTH BENEFITS OF RADISH
THE INFORMATION COMPILED IS FROM NET.
Radishes come in different forms varying in size, color and duration of required cultivation time. They can be broadly categorized into four main types-summers, fall, winter, and spring while growers classify them by shapes, colors, and sizes, such as black or white colored, with round or elongated roots. Their biting pungent flavor comes from "isothiocyanate" compound in them, which ranges from mild in case of white-icicles to be very hot in red globe and other pigmented radishes. The top greens are also eaten as leafy-vegetables in some parts of the world.
Daikon or Japanese radishes are native to Asia. They are generally grown during winter months and have elongated smooth, icy-white roots.

Black Spanish radishes are peppery and more flavorful than their white counterparts.
Green radish is native to Northern China region. Its outer peel near the top stem end features leafy-green color which, gradually changes to white color near the lower tip. Inside, its flesh has beautiful jade green color, sweet and less pungent flavor.
Watermelon radishes have watermelon like flesh inside. However, they taste sweet and less peppery, something similar to that of white varieties.
When left to grow for longer than the usual root harvest period, all radish varieties bear small flowers, which subsequently develop into edible fruit pods. Podding or a
rat-tailed radish is a type of seed pod variety grown exclusively for their long rat-tail like tapering pods. The pods feature mild radish-like flavor and spiciness.

- They are are one of very low calorie root vegetables. Fresh root provides just 16 calories per 100 g., nonetheless; they are a very good source of anti-oxidants, electrolytes, minerals, vitamins and dietary fiber.
- Radish, like other cruciferous and Brassica family vegetables, contains isothiocyanate anti-oxidant compound called sulforaphane. Studies suggest that sulforaphane has proven role against prostate, breast, colon and ovarian cancers by virtue of its cancer-cell growth inhibition, and cyto-toxic effects on cancer cells.
- Fresh roots are rich in vitamin C; provide about 15 mg or 25% of DRI of vitamin C per 100 g. Vitamin C is a powerful water soluble anti-oxidant required by the body for synthesis of collagen. Vitamin C helps the body scavenge harmful free radicals, prevention from cancers, inflammation and help boost immunity.
- In addition, they contain adequate levels of folates, vitamin B-6, riboflavin, thiamin and minerals such as iron, magnesium, copper and calcium.
- Further, they contain many phytochemicals like indoles which are detoxifying agents and zea-xanthin, lutein and beta carotene, which are flavonoid antioxidants. Their total antioxidant strength, measured in terms of oxygen radical absorbance capacity (ORAC value), is 1736 µmol TE/100 g.

In general, radishes are available year-around with peak season during winter and spring. Daikons are most flavorful and juicy during winter.
Look for roots that feature fresh, stout and firm in texture. Their top greens also should be fresh, and feature crispy green without any yellow, shriveled leaves. Avoid roots that have cracks or cuts on their surface. Look carefully for the change in their texture and color. Yellowness indicated the stock is old. If the root yields to pressure and soft, the interior likely be pithy instead of crispy.
Once at home, remove the top greens as they rob nutrients of the roots. Then wash thoroughly in clean water to rid off surface dust and soil. Store them in a zip pouch or plastic bag in the refrigerator where they remain fresh for up to a week.
Preparation and serving methods
Both root and top greens are used for cooking. Peeling may be avoided as the anti-oxidant allyl-isothiocyanates, which gives a peppery pungent flavor to radish, are thickly concentrated in the peel. Just wash the root thoroughly, trim the tip ends, and if you have to peel, then gently pare away superficial thin layer only.
