Salt is an essential seasoning in daily life. If the human body lacks of salt, people not only will suffer from the loss of appetite, but also will feel weak and feeble. However, long-term taking in too much salt is easy to affect human health, and even may induce some kinds of diseases.

First, cause damage on the stomach.
If human body takes in too much salt, the excessive sodium ions will compete with calcium ions, which will increase the excretion of calcium. Meanwhile, the sodium salt will also promote the dissolution of the gastric salt, and destroy the dynamic balance of bone metabolism, so it will easily lead to osteoporosis.

Second, make people easily suffer from cold
Modern medical study found out that, when there is too much sodium chloride in the body, the sodium ions can inhibit the activity of the respiratory cells, which will decrease the capacity of the immunity cells. At the same time, as the concentration of sodium chloride in the blood is increasing, it can also reduce the content of interferon in the body, so that the resistibility of the body will weaken. All the above reasons make people easily suffer from cold.

Third, cause gastritis and gastric cancer
When people take in too much high-salt foods, the high osmotic pressure of the salt will cause direct damage to the gastric mucosa. High-salt foods can also reduce the gastric acid and inhibit the synthesis of prostaglandin E, which has the effect of enhancing the immunity of the gastric mucosa. In such a case, it is easy to cause damage to the gastric mucosa, leading to gastritis or gastric cancer. At the same time, high-salt foods contain a large number of nitrate. It will combine with the amine in the food and form ammonium nitrate, which is a strong carcinogenic substance.

Fourth, aggravate diabetes
Foreign experts recently found out that, the sodium content in food has a direct relationship with the digestion and absorption rate of starch, as well as the blood glucose. Salt can accelerate digestion of starch by stimulating the activity of starch enzyme, or accelerate the absorption of glucose in the small intestine. As a result, scholars suggest that people who suffer from diabetes should pay attention to limit the salt intake, as a supplementary measure to prevent and treat diabetes.

In addition to the above hazards, too much salt intake will also make people easily suffer from high blood pressure, increase the burden on the heart, lead to heart failure, systemic edema and ascites, and so on.
