The formation of kidney stones is associated with calcium and uric acid in the urine. It is not related to sodium ions.To eat too much salt can not cause kidney stones.
one of the harmful effects of salt:
Cationic and anionic body potassium deficiency in human blood and cells must be equal in order to maintain the balance of electrolyte. If we eat the salt (sodium ion is a cation) too much at this time in order to balance the electrolyte will cause potassium (also a cation) with urine discharge, if insufficient intake of vegetables and fruits, body it is prone to potassium deficiency. The body can make some limp muscle potassium deficiency, intestinal wall muscle potassium can slow down peristalsis caused by potassium deficiency can cause bladder distension, urinary retention, intracellular potassium deficiency can cause low blood sugar, and cause fatigue, inattention, anxiety and so on.
too much salt two：
High blood pressure can cause the body to eat too much salt, water and sodium retention, increased blood pressure. Someone with a high salt diet fed rats after 4 months will form a fatal hypertension. Before Japanese eat salted and dried salty dried radish and pickled food, due to excessive intake of sodium, so a lot of suffering from hypertension, stroke people. Epidemiological investigation before 1997 deaths in China city residents suffering from cerebrovascular disease in the total number of deaths accounted for the first, the reason is also associated with a high salt diet.
too much salt three:
Digestive tract cancer incidence in salt itself is not carcinogenic, but long-term high salt diet may damage the gastric mucosa, the carcinogenic nitrosamines formation increased in the stomach, and gastric mucosal epithelial invasion, the cause of cancer.
Epidemiological statistics show that gastric cancer, the incidence of esophageal cancer and also eat too much salt, similar incidence this case with hypertension and stroke. According to the data survey of 574 counties in 8 provinces in China, the mortality of gastric cancer was positively associated with per capita consumption of salt. There are 127 counties in Henan investigation and analysis, the annual sales of 7.8 kilograms of salt in residents of the area are esophageal cancer, gastric cancer incidence area, and sales in the 5 kg area of esophageal cancer, gastric cancer mortality is low. The corresponding previous statistics show that Japan, Finland and most of Eastern Europe, residents of the daily salt intake more than 15 grams, the incidence of gastric cancer is very high in the 60.20 After the 1990s, the Japanese diet gradually westernized, eat less salt, milk products increased, the death rate of gastric cancer has declined. Eat every day how much salt for our health care sector advocate people diet not too salty, eat salt best in 6 ~ 8 grams, it will remind the most areas of our country the northern residents to change the habit of eating salty, advocate eat more fresh vegetables, fruits, a prevention of hypokalemia, two foods containing vitamin C can block the synthesis of nitrosamines in the stomach, has anti-cancer effect. Despite the low salt diet on human health benefits, but also can not limit the intake to limit salt, sodium chloride intake is necessary to maintain life activities, the lack of body salt will cause fatigue, sweating and organ dysfunction. Many doctors of cardiovascular specialist by a large number of clinical data also found that although people with low salt intake Blood pressure is not necessarily high, but still can be suffering from atherosclerosis and coronary heart disease, and the incidence of myocardial infarction is not low, so that you can not avoid the salty and do not eat salt, should be based on physiological needs.
