Each 100 grams of cucumber contains 102 mg of potassium. According to the testing data of the Chinese Food Composition Table, every 100 grams of cucumber contains 9 mg of vitamin C, 90 micrograms of beta-carotene, 102 mg of potassium, 24 mg of calcium, and 0.5 g of fiber.

1. Potassium is an essential nutrient for the human body. Potassium is contained in various body fluids. Potassium is involved in sugar and protein metabolism, and has physiological functions such as maintaining the body's acid-base balance and maintaining the normal functions of nerves, muscles, and cardiomyocytes. .

2. Potassium is easily soluble in water, and most of the potassium in food is concentrated in cereal skins, peels and muscles. Therefore, the potassium content of fine grains is lower than that of whole grains, the potassium content of peeled fruits is lower than that of peeled fruits, the potassium content of fat meat is lower than that of lean meat, and the potassium content of canned fruits or boiled fruits is lower than that of fresh fruits. Rich broths, vegetable soups and fresh juices contain more potassium.

3. When hypokalemia occurs (blood potassium concentration is less than 3.5mmol/L), a high-potassium diet should be given. You can choose lean meat, fish, shrimp and beans rich in protein. Food (except low-protein diet); whole grains, fresh fruits and vegetables; replace some staple foods with potassium-rich potatoes and taro; thick broth, vegetable soup and fresh fruit juice drinks.

4. When hyperkalemia occurs (blood potassium concentration is higher than 5.5mmol/L), a low-potassium diet should be given. Use the above-mentioned high-potassium foods as little as possible, and try to choose foods containing less than 250 mg of potassium. , you can soak food in water or boil it to remove the soup to reduce potassium content.
