Nutrition, Functions & Cooking Tips


It is an annual plant of the Chenopodiaceae family native to Siberia, China, and Japan, and is in season from summer to early autumn.
It got its name from its resemblance to the seaweed hijiki.
In Japan, it grows wild on sandy coasts and has been eaten since the Edo period.
○ Nutritional value: Rich in carotene, vitamin C, and potassium, and also contains a balanced amount of minerals such as calcium and magnesium.
It contains 680mg of potassium, 150mg of calcium, and 51mg of magnesium per 100g, making it an effective source of minerals. Potassium helps excrete unnecessary sodium, which helps prevent and improve high blood pressure.
Calcium is a component that strengthens bones. When cooking, it is recommended to simmer it with dried small sardines. Vitamin D helps increase calcium absorption.
The carotene content is similar to that of komatsuna, which suppresses active oxygen and boosts immunity. Its synergistic effect with chlorophyll also strengthens the skin, making it less likely to catch a cold.
