The potassium concentration in human serum is only 3.5~5.5mmol/L, but it is necessary for life activities. The main role of potassium in the human body is to maintain acid-base balance, participate in energy metabolism, and maintain normal neuromuscular function. When potassium is lacking in the body, it can cause general weakness, fatigue, weakened heartbeat, and dizziness. Severe potassium deficiency can also lead to respiratory muscle paralysis and death. In addition, low potassium can slow down gastrointestinal motility, lead to intestinal paralysis, aggravate anorexia, and cause symptoms such as nausea, vomiting, and abdominal distension. Clinical medical data also prove that people with heatstroke have reduced blood potassium.

The key to preventing and treating hypokalemia is potassium supplementation. Oral 10% potassium chloride solution can be used clinically, but the safest and most effective method is to eat more potassium-rich foods, especially fruits and vegetables. Fruits rich in potassium include bananas, strawberries, citrus, grapes, grapefruits, watermelons, etc. Vegetables such as spinach, yams, edamame, amaranth, and green onions are also rich in potassium. Soybeans, mung beans, broad beans, kelp, seaweed, yellow croaker, and chicken , milk, cornmeal, etc. also contain a certain amount of potassium. Various juices, especially orange juice, are also rich in potassium and can replenish water and energy. According to measurements, it contains 1.1% to 2.3% potassium, so tea is the best summer drink.

Potassium is an essential substance that is indispensable for maintaining life. It works together with sodium to regulate the balance of water in the body and regularize the heartbeat. Potassium is important for chemical reactions within cells and plays a very important role in helping to maintain stable blood pressure and conduction of nerve activity.

Potassium deficiency will reduce muscle excitability, prevent muscle contraction and relaxation from proceeding smoothly, and lead to fatigue. In addition, it will hinder intestinal peristalsis and cause constipation; it can also lead to edema, hemiplegia and heart attack. When the body's potassium intake is insufficient, sodium will bring a lot of water into the cells, causing cell rupture and edema. A lack of potassium in the blood can cause high blood sugar levels, leading to hyperglycemia. In addition, potassium deficiency causes the most serious damage to the heart, and potassium deficiency may be the main cause of death from heart disease in humans.

The main symptoms of potassium deficiency in the human body are: tachycardia and irregular heartbeat, muscle weakness, numbness, irritability, nausea, vomiting, diarrhea, hypotension, mental confusion, and psychological apathy.

Children should consume 1,600 mg of potassium per day, and adults should consume 2,000 mg per day. Foods containing potassium include dairy products, fish, fruits, legumes, meat, poultry, unprocessed grains, green leafy vegetables, etc. For example, apricots, bananas, brewer's yeast, brown rice, figs, garlic, raisins, sweet potatoes, etc.

Magnesium helps maintain potassium in cells, but excessive intake of sodium, alcohol, and sugar; taking diuretics, light doses, corticosteroids, and excessive psychological stress will hinder the absorption of potassium. Please accept, thank you
