salt is the first of all flavors. If you don’t have salt when eating, no matter how fragrant the food is, it will taste tasteless. Salty is the most basic taste. It can blend the sour, sweet, bitter and spicy taste and stimulate the fresh aroma of the ingredients. You can not add soy sauce, vinegar, chili, sugar and other seasonings when cooking, but you must add salt.
salt also plays a very important role in the human body. It can provide necessary sodium elements, clean up stomach fire , participate in body fluid metabolism, replenish body salt, and maintain health. In daily life, we cannot do without salt. While we enjoy the stimulation of taste buds, we are also quietly harming our health by the "sodium" in salt.
So why does excessive sodium intake increase blood pressure? How to participate in physiological activities? Let’s learn more about it below. How does the salt eaten by

How does the blood pressure increase? What harm does "eat salty" cause to the body? Eating too much salt will increase blood pressure. This is because excessive intake of water and sodium ion can lead to increased blood volume and increase blood pressure. People with a long-term high-salt diet can easily lead to increased blood pressure. This is because the main components of salt are sodium chloride . Sodium ions and chloride ion are present in cells. In the external fluid, potassium ion is present in the intracellular fluid, which can maintain sodium and potassium balance under normal circumstances. When
When you intake too much sodium ions, it is easy to cause osmotic pressure to change , causing increased extracellular fluid to increase sodium, and after water retention, blood volume increases, which may lead to increased blood pressure. Therefore, you must strictly pay attention to controlling salt intake in your daily diet, and do not consume more than three grams of salt a day.
. The main components of salt are sodium chloride. Sodium ions and chloride ions are both present in the extracellular fluid, and potassium ions are present in the intracellular fluid. Under normal circumstances, dynamic equilibrium is maintained. When the increase in sodium ions and chloride ions is due to changes in osmotic pressure, it causes the increase in extracellular fluid, which causes water and sodium to retention, increase intercellular fluid and blood volume, and at the same time, the return of the blood volume, the ventricular filling and output volume are increased, which can increase blood pressure.
. The sodium ions in the extracellular fluid increase, and the concentration gradient of sodium ions in and outside the cell increases, and the sodium ions in the cell also increase, and cell swelling occurs. After the smooth muscle cells of the small arterial wall swell, on the one hand, it can increase the peripheral resistance of the lumen stenosis, and on the other hand, it can increase the reactivity of the small arterial wall to the blood constricting substances in the blood, causing arterial spasms, increasing the resistance of the small arterial arterial walls throughout the body and increasing blood pressure.
Therefore, in daily life, you must control your intake of salt. Patients with Hypertensive cooperate with doctors to take antihypertensive drugs for treatment, relieve symptoms, pay attention to a light diet, drink appropriate water, promote excretion, and improve your own resistance. Patients with hypertensive dysfunction must pay attention to relax and avoid being too nervous, excited or too anxious. A good mood is also very helpful for controlling blood pressure.

What are the harms to the body when consumed too much salt?
. Injury to kidney function: The kidney is the most important and important metabolic organ in the human body. Most metabolic waste is excreted after the kidney produces urine. If excessive salt is consumed, the concentration of protein in the urine will increase the kidney burden, and over time, symptoms such as swelling and kidney damage will occur.
. Injury to stomach health: Eating too much salt will reduce the viscosity of stomach mucus and weaken the protective effect of the gastric mucosa on the stomach. In this way for a long time, it will damage stomach health and increase the risk of stomach disease . Data shows that the occurrence of gastric cancer is positively related to salt intake.
. Edema: The main component of salt is excessive intake of sodium, which will increase the sodium ion content in the body and promote the flow of water from plasma to tissue fluid, thereby causing symptoms of edema.
4. Prone to colds: People with excessive salt are more likely to catch colds. This is because high concentrations of salt will hinder the secretion of saliva, inhibit the activity of respiratory bacteria, and reduce the body's respiratory tract's ability to resist bacteria. They are prone to colds due to the increase in the chance of infection with bacteria.
5. Injury to the skin: After salt enters the body, it is decomposed into sodium ions and chloride ions, and it has positive significance for maintaining acid-base level balance and osmotic pressure. Excessive salt intake will increase the concentration of sodium ions and promote the loss of water. The skin becomes dry due to lack of water, and even skin problems such as dull skin and freckles.
6. Causes headache: High concentration of salt will increase the viscosity of the human body's blood, slow down the blood flow rate and increase blood pressure. Long-term intake of excessive salt will cause headache symptoms. A large amount of salt will increase the concentration of cholesterol in the plasma, reduce the rate of fat removal, and increase the risk of cardiovascular disease.
7. Causes abnormal blood pressure: Long-term intake of excessive salt will cause severe water and sodium retention in the body, and abnormal increase in blood pressure in the body.
8. Cause osteoporosis : The more salt you eat, the more urine calcium will be excreted from the body, which will increase the loss of calcium in the bones, thereby promoting the formation and onset of osteoporosis. The "Hyper Guide to Chinese Residents " reminds that daily diet should follow the dietary principle of less oil and less salt. Adults should not consume more than 5 grams of salt per day.

High blood pressure, how long will it take to take less salt?
Hypertension is mostly due to unknown primary causes, which may be caused by obesity, genetics, high-salt food intake, fatigue and other factors. Due to individual differences, it is impossible to determine the specific time for less salt to lower blood pressure. If blood pressure cannot return to normal, anti-hypertensive drugs should be used to maintain blood pressure at a normal level.
Eating less salt is helpful for lowering blood pressure, but it is only a way to control blood pressure. Eating less salt can slow down water and sodium retention, reduce blood vessel tightness, and help reduce blood pressure, but cannot cure hypertension and limit sodium salt. The most important thing is prevention and treatment measures. Recently, the daily salt intake is controlled within 6 grams, and the daily sodium intake is less than 2.4 grams.
should be vegetarian in terms of diet. Strictly control the intake of fat foods in normal times, and eating more vegetarian food can well control the reduction of blood pressure. Patients with hypertension should eat more coarse grains, mixed grains, fresh vegetables, fruits, soy products, lean meat, fish, chicken and other foods, eat less animal fat and greasy foods, eat less irritating foods, such as sugar, strong tea, and coffee, exercise in moderation, lose weight, and stay happy.
