What are the functions of the macroelement potassium, its lack and how to properly supplement it?

<> "Nutrition Knowledge, Popular Science, Macroelements-Potassium."

Physiological function of potassium.

Maintain the normal metabolism of sugar and protein;

Maintain normal intracellular osmotic pressure;

Maintain the normal function of the heart muscle;

Maintain normal acid-base balance inside and outside cells;

Prevent high blood pressure.

Potassium deficiency, in which a person's total amount of potassium decreases, can cause potassium deficiency.

Muscle weakness, paralysis, arrhythmia, rhabdomyolysis and renal dysfunction.

Digestive tract disorders, such as frequent vomiting, diarrhea, gastrointestinal drainage, long-term use of laxatives or laxatives, etc.

Various kidney diseases, mainly tubular dysfunction, cause large amounts of potassium to be lost in the urine.

Potassium loss can occur due to hot work or heavy physical work, and heavy sweating.

Dietary Reference Intakes.

Food comes from the source:

Most foods contain potassium, but fruits and vegetables are the best for potassium**.

Foods with potassium content higher than 800mg per 100g of food include seaweed, soybeans, mushrooms, etc. Filial piety.

Lack of potassium will suffer from "summer nap", also known as "summer burnout" in medicine, which is due to the hot summer and high temperature, which makes the human body sweat a lot, and a large amount of potassium can be discharged with sweat, and because potassium is not replenished in time, it leads to fatigue and lack of energy in summer.

1. Potassium is an indispensable element in the human body, and the potassium content in the body of ordinary adults is about 150 grams, and its role is mainly to maintain the normal function of nerves and muscles.

2. Once the human body is deficient in potassium, normal exercise will be affected.

3. Potassium deficiency in summer not only reduces energy and physical strength, but also reduces heat tolerance, making people feel tired and weak.

4. When there is severe potassium deficiency, it can lead to acid-base balance imbalance, metabolic disorders, arrhythmia, muscle weakness and laziness in the human body.

1. Promote the activation of enzymes.

The activation of enzymes is one of the most important functions of potassium in plant growth, and potassium has been found to be the activator of more than 60 enzymes. Therefore, potassium is closely related to many metabolic processes in plants, such as photosynthesis, respiration, and the synthesis of carbohydrates, fats, and proteins.

2. Promote photosynthesis and transportation of photosynthetic products.

improve photosynthetic efficiency; Adjust the opening and closing of the pores, control the inflow and exit of CO2 and water; Promotes the synthesis of carbohydrates and accelerates the flow of photosynthetic products.

3. Enhance the stress resistance of plants.

Potassium can reduce soluble amino acids and monosaccharides, increase cellulose and thicken cell walls in crops. The accumulation of potassium in the root system of crops creates an osmotic pressure gradient, which can enhance water absorption. Potassium can close the stomata of crop leaves in times of drought and water shortage, so as to prevent water loss. Therefore, potassium can enhance the resistance of crops to disease, cold, drought, lodging and salt.
