Potassium is good, you should eat more
Some people have a heavy taste and don’t know the harm of a high-salt diet; some people know that the diet should be less salt, but it is not well controlled; others It is believed that the sodium content of potassium salt is relatively low, and you can eat more. Over time, it will cause a series of troubles and even diseases of a high-salt diet.
A high-salt diet is very unhealthy. High-potassium and low-sodium salt is a better choice among all kinds of salt, but potassium salt is also salt, so you should still pay attention to controlling the dosage.
⊙High-salt diet is harmful to health
According to the results of national nutrition and health monitoring, the average daily salt intake per person in my country is 10.5 grams, which is much higher than the recommended dietary intake (6 grams/day); 65% of adult residents have exceeded the recommended intake, and 34% of adult residents have more than 10% of the recommended intake of salt. Research evidence shows that hypertension, stroke and gastric cancer are all related to excessive salt intake.
1. High salt intake increases the risk of high blood pressure
Hypertension is an important risk factor for cardiovascular diseases such as stroke, so high salt intake can lead to the risk of cardiovascular diseases such as stroke. There are four main mechanisms for high salt intake to cause high blood pressure: too much sodium ions can cause water and sodium retention, leading to increased blood volume and blood pressure; sodium ions can cause cell edema and narrow the vascular cavity; sodium ions can increase blood vessels Sensitivity to catecholamine vasoconstrictor factors; increased intracellular sodium ions will inhibit sodium-calcium exchange, leading to an increase in calcium ion concentration in vascular smooth muscle and causing vascular smooth muscle contraction. A high-salt diet can also change the regularity of changes in blood pressure during the day and night, becoming high during the day and high at night, greatly increasing the risk of cardiovascular accidents.

2. High salt intake can increase the risk of gastric cancer
Long-term high-salt diet can cause higher osmotic pressure between gastric mucosa and the outside world, which can lead to direct damage to the gastric mucosa, causing widespread diffuse hyperemia, edema, erosion, and ulcer Such pathological changes increase the risk of gastric mucosal cells becoming cancerous; excessive intake of salt will also reduce gastric acid secretion.Thereby inhibiting the synthesis of prostaglandin e, reducing the defense ability of the gastric mucosa, increasing the risk of gastric lesions and gastric cancer.
3. High salt intake may induce kidney disease and osteoporosis
Salt is excreted by the kidneys. Relevant studies have found that a high-salt diet will increase the protein content in the urine excreted by a person, and the increase in the protein content in the urine is A red flag of kidney damage and kidney disease. More salt than the body needs will increase the burden on the kidneys. The more excess salt, the heavier the burden on the kidneys and the greater the possibility of kidney disease. When sodium ions are metabolized and excreted from the human body, some calcium ions will be lost. People on long-term high-salt diets generally have higher levels of calcium in their urine. Over time, excessive calcium loss in the body will increase the risk of osteoporosis and increase the risk of kidney stones.
