Boost Up Immune System
Komatsuna (Japanese mustard spinach) contains a lot of vitamin E and carotenoid which elevate the activity of immune cells. Vitamin E in Komatsuna is 9 times more than cabbage which is also said to boost up the immune system and carotenoid in Komatsuna is 60 times more than cabbage. Komatsuna also contains isothiocyanate a lot, which increases the number of immune cells.
Isothiocyanate is only found in cruciferous vegetables such as cabbage, broccoli, daikon or cauliflower.
Isothiocyanate is weak at heat so it is more effective to eat them raw. When the vegetable is cut into small pieces, more isothiocyanate is produced. So smoothie is recommended. Blend Komatsuna (50 grams), apple (a half) and water (100 cc) for 2 persons.
Another recommended recipe is pickled Komatsuna.
Mix Komatsuna (1 stem) with salt (appropriate amount), sugar (1 tea spoon), vinegar (1 tea spoon), kelp (appropriate amount) and red pepper (appropriate amount).
Eating 1 stem of komatsuna (50 grams) a day is effective. It is important to eat every day continuously because nutrition doesn’t remain in the body. It is good to eat other kinds of cruciferous vegetables not to become tired of eating them.
