Daikon is widely used in Japan to soothe throat inflammations and to treat diseases of the upper respiratory tract thanks to its expectorant and mucolytic properties. For a greater effect in this sense it is sometimes used in combination with honey.

✓ Facilitates digestion

Not only does isothiocyanate stimulate the secretion of gastric juices favoring digestion, but daikon has a direct action on digestion due to the digestive enzymes amylase and esterase it contains, in fact in Japan it is often served at the end of a meal to facilitate the digestion of fatty and fried. It is therefore a good natural digestive.

✓ Cancer prevention

Thanks to the presence of glucosinolates and isothiocyanates, daikon has shown protective effects against oncological diseases, especially against cancer of the colon and organs of the digestive system, such as the pancreas

✓ Fights obesity

Studies conducted on laboratory guinea pigs affected by obesity show that daikon, thanks to the action of isothiocyanate, is able to reduce the accumulation of fat in the liver and reduce the levels of inflammation generated by the accumulation of adipose tissue, therefore it could be an aid in the management of obesity and metabolic syndrome

✓ Beneficial for the cardiovascular system

The daikon plays a role in the prevention of cardiovascular diseases because thanks to the action of trigonellin, it is able to improve the functionality of the endothelium of the blood vessels, ie the tissue that covers them internally, protecting and strengthening them

Daikon is a food with a low glycemic index, which lends itself well to being used by diabetics also because its fibers and the numerous anti-inflammatory compounds it contains help to correctly manage the glucose introduced during the meal, avoiding glycemic peaks and sudden absorption of sugars.

Vitamin C contained in good quantities also contributes to reducing oxidative stress generated by intense physical activity.

Of course, the best way to take advantage of the properties of daikon and its benefits is to eat it raw, because with cooking some of the beneficial bioactive compounds are denatured and therefore lose their effectiveness. It is not at all difficult to eat raw daikon because it is the ideal match for many dishes, it can in fact be added to salads as you would for a radish or a carrot, eat it in a pinzimonio with oil and salt and grate it raw on fish dishes. or meat.

Cleaning the daikon is simple. If we buy a daikon root supplied with leaves we must remove them and then wash it thoroughly. After that you can peel it with a knife or a potato peeler and cut it into slices, julienne, chunks or grate it with a grater depending on the use we want to make of it.

Daikon is also excellent cooked and can be added to winter soups or soups, for example as an alternative or partial replacement for potatoes. In summer we can instead add it to rice or other cereal salads, for an even fresher taste.

If you want to use it as a side dish, you can cook the daikon steamed or in a pan by adding vegetable broth or simply water, lengthening the cooking times until it is soft. Of course, fried daikon, like potatoes, is delicious! If we want to avoid frying, we can cut the daikon into thin slices and put them in the oven to make tasty chips.

Another way to taste daikon is marinated in salt, a preparation known in Japan as “namasu”: after washing and slicing the root, it is salted for about half an hour, then rinsed, dabbed and put on all in a glass jar with a marinade of water, rice vinegar and sugar. In this way it can be stored for a few days in the refrigerator.

There are many Japanese and Korean recipes that use daikon and often, unknowingly, we may have happened to eat it with sushi or in the typical Japanese miso soup.
