There are two ways to eat water chestnut: raw and cooked. Raw water chestnut has the functions of clearing away heat and resolving phlegm, moistening intestines and relaxing bowels, and is suitable for patients with symptoms such as yellow cough, dry throat, thirst, sore throat and hot stool. Cooked water chestnut has the functions of stimulating appetite, promoting digestion, inducing diuresis and stopping diarrhea, and is suitable for patients with anorexia, dyspepsia, dysuria, dysentery and diarrhea.
It should be noted that water chestnut is a cold food, which is not suitable for people with spleen and stomach deficiency and blood deficiency, and it is not suitable for long-term consumption in cold winter, so as not to damage the yang of human body by cold and cool qi. In addition, water chestnut contains more starch, and diabetics should also eat it carefully.
Because water chestnut grows in mire, there are a lot of bacteria and parasite eggs on its surface, especially ginger eggs, so people who like to eat raw water must pay attention to the cleaning of water chestnut. When eating raw water, rinse it with tap water, peel it, and scald it with boiling water before eating.
