1, quality. First of all, the mineral salt relative to the sea salt is more pure, good quality, because the mineral salt raw materials are extracted from thousands of meters deep wells below the Jurassic geological era of natural brine and rock salt deposits, rich in various types of natural mineral elements, impurities, mineral salt in color and shape are better than sea salt.

2. Safety. With the development of modern industry, harmful chemical substances on the raw material of sea salt - seawater pollution is becoming increasingly serious, while the raw material of mineral salt is not affected in any way.

Overall, in terms of quality and safety, mineral salt is better than sea salt.

The dangers of eating too much salt:

1, a long-term high-salt diet is easy to trigger high blood pressure. Studies show that people who eat 15 grams of salt a day, the incidence of hypertension is about 10%, high salt diet is an important risk factor for hypertension. Because the salt in the sodium ion is absorbed into the blood, causing the body of water and sodium storage, resulting in an increase in blood volume, hypertension, but also cause vascular smooth muscle cell edema, narrowing the lumen of the blood vessels, aggravating high blood pressure.

2, high salt diet easily induced atherosclerosis. Eat more salt will make the plasma cholesterol significantly higher, long-term cholesterol risk factors stimulate the inner wall of blood vessels, inducing the formation of atherosclerosis.

3, high salt diet is easy to cause stomach cancer. After consuming excessive high salt food, the osmotic pressure of salt is high, causing direct damage to the gastric mucosa. High-salt food will also reduce the secretion of gastric acid, inhibit the synthesis of gastric mucosal protective factor prostaglandin E2, easy to produce gastritis or gastric ulcer. At the same time, high salt food contains nitrate, in the stomach to form carcinogenic substances ammonium nitrite.

4, long-term high salt diet prone to colds. High salt concentration will inhibit the activity of respiratory cells, inhibit their ability to fight disease; at the same time will also reduce saliva, so that the oral lysozyme reduction, increase the virus and germs in the upper respiratory tract infection opportunities.

5, high salt diet accelerate bone calcium loss, leading to osteoporosis. Dietary sodium salt is too much, in the renal tubular reabsorption of excessive sodium ions and calcium ions competition, so that the excretion of calcium increased, leading to a reduction in the utilization of calcium in the body. At the same time, sodium salt stimulates the parathyroid glands, increasing the secretion of calcitonin, leading to hypocalcemia and inducing osteoporosis.
