As the saying goes, "there are seven things to do when opening the door. Firewood, rice, oil, salt, soy sauce, vinegar and tea.". Salt is an important seasoning in our cooking process. Salt is the first of the five flavors. But when salt and medicine meet each other, what should we pay attention to? Listen to the pharmacist talk about the special requirements of several drugs on daily salt consumption. Let's see if your "salt" value exceeds the standard. The main component of table salt is sodium chloride. The inorganic salt sodium ion contained in it is one of the main factors affecting the osmotic pressure of plasma crystal, and plays an important role in maintaining cell morphology and function, maintaining plasma capacity and maintaining the electrolyte balance of the body. High salt intake in diet may lead to high blood pressure; If it is too low, it may cause hyponatremia, fatigue and disturbance of homeostasis. Therefore, salt restriction mainly refers to sodium restriction. High salt and no salt are not allowed. Salt intake should be appropriate. From the perspective of nutrition, the World Health Organization recommends a daily salt intake of 5g (about 2000mg sodium); The new version of dietary guidelines for Chinese residents released in April 2022 also recommends that adults take daily salt lt; 5g (the previous recommended intake in 2016 was lt; 6g). lt; p=""gt; Low salt and limited sodium diet in this way, the sodium limited diet is generally divided into the following three types: low salt diet provides 2000 mg of sodium throughout the day. In addition to the sodium contained in the food itself, it is allowed to add 2-3 g of salt or 10-15 ml of soy sauce when cooking or eating. Do not use any high sodium or salty food in the diet, such as pickled vegetables, sweet sauce, fermented bean curd, salted eggs, sausages, sausages, etc. The salt free diet is provided with 1000 mg of sodium throughout the day. The above-mentioned high sodium or salty food should not be used. At the same time, soy sauce and salt should not be added during cooking. The daily sodium supply of low sodium diet shall be controlled within 500 mg. In addition to the requirement of salt free diet, it is also necessary to limit some foods with high sodium content, such as Songhua egg, kelp, jellyfish, alkali or baking soda, and vegetables with high sodium content, such as root vegetables, Artemisia stem, fennel, etc. The 2018 edition of China's guidelines for the prevention and treatment of hypertension pointed out that all patients with hypertension should take various measures to limit their sodium salt intake. To prevent hypertension and reduce blood pressure in hypertensive patients, sodium intake was reduced to 2400 mg / D (6 g sodium chloride). Salt restriction can also increase the antihypertensive effect of angiotensin-converting enzyme inhibitors (ACEI). Therefore, patients taking antihypertensive drugs are advised to avoid high salt diet. Diuretics diuretics promote the excretion of water and sodium to exert diuretic effect, and are widely used in the treatment of hypertension, heart failure, edema and other diseases. The intake of salt will increase the sodium level in the body, so the high salt diet will antagonize the sodium excretion effect of diuretics; Too little salt intake may increase the risk of hyponatremia caused by diuretics. Therefore, it is suggested that patients taking diuretics should not over control or increase sodium salt intake. Glucocorticoids and glucocorticoids, due to their aldosterone like effects, can maintain sodium and potassium secretion, promote water and sodium retention, and may cause adverse reactions such as urinary retention, water, electricity, water, and balance disorders. Therefore, it is recommended to take glucocorticoids during
