Problem description:
Because summer is hot and sweaty, what should we pay attention to in diet or eating?
Analysis:
Adding a little sodium chloride to drinking water can play a good preventive role.
People always think that a lot of sodium will be lost after sweating in summer, as long as sodium is replenished in time, but it is not. According to Greeny, chief physician of internal medicine of Guangzhou Friendship Hospital, people excrete sodium and necessary potassium while sweating. Potassium, like sodium, is the main cation in human cells and an important component to maintain intracellular osmotic pressure. Participate in the synthesis of sugar and protein, the energy metabolism of adenosine diphosphate into adenosine triphosphate, the normal functions of nerves and muscles, and the normal movement of myocardium. When the human body is short of potassium, it will feel tired, weak, listless, physically exhausted, and its heat resistance will also decline. Severe potassium deficiency can lead to arrhythmia, muscle weakness and even edema. Therefore, after sweating in summer, we should not only pay attention to sodium supplementation, but also pay attention to potassium supplementation from the diet.
There are many ways to supplement potassium in life. For example, oral rehydration salts (ORS) in drugs contain electrolytes needed by human body, such as sodium chloride and potassium chloride, which can be used to prevent mild diarrhea and supplement excessive sweating. More acceptable methods such as drinking tea, because tea is rich in potassium; Eat more beans rich in potassium, such as mung beans, black beans, red beans, mung beans, broad beans, etc. Potatoes, parsley, bananas and oranges in vegetables and fruits also contain more potassium; In addition, milk, chicken, carp, yellow croaker, corn, sweet potato and other foods also contain a lot of potassium. When people are sweating in hot summer, if they can selectively eat more foods rich in potassium, they can relieve fatigue and keep their energy.
