Daikon (literally “big root”), also known by many other names depending on context, is a mild-flavored winter radish (Raphanus sativus) usually characterized by fast-growing leaves and a long, white, napiform root. Originally native to Southeast or continental East Asia, daikon is harvested and consumed throughout the region (as well as in South Asia).

Daikon Radish refers to Japanese Radish or Chinese Radish. They are both the same except that Japanese Radish is thinner and longer, compared to Chinese Radish. It looks like a white carrot and has a crisp texture with a mild taste compared to normal radish. It is used mainly in Oriental dishes, but can also be eaten raw in a salad.

There are several types of radishes available in the market, but daikon radish is the most popular from the medicinal point of view. Another popular radish for its healing properties is the black radish, which is common in the West. Daikon radish is of course, common in the East.

Besides its medicinal and healing properties, the high nutritional content including Vitamin A, C, E and B-6, potassium, magnesium, calcium, iron and fiber are some of the reasons why daikon radish or Chinese radish should be part of your diet.

Raw daikon is used throughout Japan to complement the taste of oily or raw foods and, more importantly, to aid in their digestion. Laboratory analysis has shown that the juice of raw daikon is abundant in digestive enzymes similar to those found in the human digestive tract. These enzymes – diastase, amylase, and esterase – help transform complex carbohydrates, fats, and proteins into their readily assimilable components. Traditional Japanese restaurants serve grated daikon (daikon oroshi) in tempura dip to help digest oils, or shredded daikon with raw fish to help digest the protein. Grated daikon is a wonderful aid to people with a weak digestive system. It is important, however, to use grated daikon immediately. In just thirty minutes nearly 50 percent of its enzymes are lost.

Daikon and radish sprouts contain high levels of glucoraphenin, a glucosinolate which hydrolyses to form sulphoraphene. Sulphoraphene, like sulphoraphane from broccoli, is a potent inducer of phase 2 detoxification enzymes and consequently has potential anti-cancer action. Unlike broccoli however, daikon and radish do not possess epithiospecifier protein, a protein that inhibits conversion of glucosinolates to isothiocyanates, and consequently they may represent more suitable sources of phytochemicals with anti-cancer potential.
