Adults have 30 grams of oil and 6 grams of salt every day.
Long-term intake of too much salt is harmful to human health, which will lead to hypertension and osteoporosis. It is reported that the World Health Organization proposes to change the daily salt intake of adults from 6 grams to 5 grams.

3.5 grams of salt can fill a beer bottle cap. However, even if you know that beer caps can be measured, few people can really abide by them. In this regard, Meng Xiangzhong, chief physician of the Department of Gastroenterology, Li Huili Hospital, specially reminded that a long-term high-salt diet is one of the inducing factors of diseases such as hypertension and gastric cancer. Try to use less salt in your life to make your taste fade.
Salt is an essential substance in the human body, which can adjust the balanced distribution of water in the human body, maintain the osmotic pressure inside and outside the cell, ensure the pH value necessary for the action of pepsin, maintain the balance of pH value in the body and maintain the normal circulation of body fluids.

The influence of salt intake on human health should not be underestimated. Eating too little salt can lead to low sodium content in the body, loss of appetite, weakness of limbs and dizziness. However, too much salt intake will do more harm to the body.
First, excessive salt intake can lead to high blood pressure. The main component of salt is sodium chloride. Once sodium ions enter the body, it will increase the osmotic pressure of crystals in plasma. In order to maintain the balance of osmotic pressure inside and outside blood vessels, a lot of water will remain in blood vessels, which will lead to the increase of blood volume, the increase of blood vessel burden, the decrease of blood vessel elasticity and the increase of blood pressure.
Second, excessive salt intake can cause edema. Excessive salt intake will change the osmotic pressure inside and outside cells in human tissue fluid, so that water will flow out from inside cells, leading to water and sodium retention in the body. At the same time, eating too much salt will make people feel thirsty and need to drink a lot of water to relieve it, thus further increasing the water retention in the body and leading to local edema in the human body, especially those with renal insufficiency.

In addition, eating too much salt will make people feel thirsty and need to drink a lot of water to relieve it. Long-term intake of salt will lead to edema and increase the burden on the kidneys. ? For salt intake, "adding salt at meals" is the best method. Don't add salt when cooking. Add salt to the pot after serving. At this time, the salt only adheres to the surface of the dish and cannot penetrate into the interior, but the salty taste is not reduced, but the salt consumption can be reduced by nearly half.
