Hypertension and sodium in salt have a greater relationship. When it comes to hypertension, it is often thought that patients should eat less salt, not knowing that the purpose of eating less salt is not the salt itself, but to reduce the intake of sodium in salt, or more precisely, to reduce the intake of sodium ions in it. Although sodium ions have a role in maintaining the body’s osmotic pressure and acid-base balance, excessive intake may cause many problems. First, the relationship between sodium ions and hypertension: hypertension may occur due to genetics, the environment, lifestyle habits and drug stimulation factors, and some people are caused by secondary diseases. Excessive sodium intake can, on the one hand, cause water and sodium retention in the body, increased blood volume, resulting in an increased burden on the heart. On the other hand, chronic high sodium in the body can also lead to edema of vascular smooth muscle cells, thinning of blood vessel lumens, and increased resistance to blood flow. Both of these factors can contribute to an increase in blood pressure, which in turn aggravates the symptoms of hypertension, and patients may subsequently experience adverse reactions such as dizziness and headache. Second, the harm of excessive sodium intake: even normal people on a long-term high-sodium diet will cause some harm to the body, excessive sodium ions may affect the human cardiovascular system, digestive system and even bone. 1, cardiovascular system: long-term consumption of food containing high sodium ions will make the heart overwhelmed, resulting in increased workload of the heart, thus affecting blood pressure, the body’s blood supply and other normal Physiological activities; 2, the digestive system: a large amount of sodium ions will stimulate the gastric mucosa, resulting in excessive secretion of gastric acid, which in the long run may corrode the stomach wall, increasing the chances of gastric disease, and may lead to gastric cancer; 3, the movement system: excess sodium ions in the body, will be excreted, while calcium ions will also be lost along with the sodium ions, increasing the risk of osteoporosis. Third, daily diet advice: daily diet contains more sodium ions in various condiments, sauces, pickled, smoked and baked goods. In order to avoid the above-mentioned hazards, it is recommended that the general population, especially those with high blood pressure, adopt the right habits to reduce the intake of sodium ions, supplement potassium ions and improve their lifestyle to protect their health.1. Low sodium diet: control the daily intake of sodium ions, you can choose foods with low sodium ion content, such as potatoes, celery, cabbage, apples, etc. At the same time, reduce the intake of high sugar, high salt food, so as to reduce the intake of sodium ions; 2, change the use of salt: the World Health Organization recommended that each person can consume 5g of salt per day, reduce the use of salt, can change the intake of sodium ions, for the “heavy” people, need to try to adapt to such seasoning. In addition, low-sodium salt can be used for seasoning, which can also help reduce sodium intake to some extent. You can also use other condiments to replace salt to achieve the purpose of a healthy diet; 3, supplemental potassium ions: appropriate intake of some potassium ions can play a role in helping the sodium ion discharge, so in the choice of condiments or daily meals, you can consciously choose foods containing potassium, such as high potassium salt, kelp, peanuts, bananas, etc..
