1, hypertension. A high-salt diet is harmful to high blood pressure.
2. Liver and kidney diseases. Sodium is mainly excreted through the kidneys, and eating too much salt will increase the metabolic burden of the liver and kidney.
3. Cardiovascular diseases. It can cause ischemia or bleeding in the heart, brain and whole body tissues.
4. obesity. A study by University of London found that a high-salt diet can easily lead to obesity. Every increase in 1 g salt increases the risk of obesity by 25%. Moreover, eating salty food will inevitably lead to overweight.
5, calcium loss. The intake of sodium is closely related to the excretion of calcium in urine. The main component of salt is sodium. The more sodium the human body excretes, the more calcium it loses. In the long run, it is easy to lose calcium, and then osteoporosis occurs.
6, hurt the stomach. Gastropathy is closely related to bad diet. High-salt food can damage gastric mucosa and cause gastritis or gastric ulcer. In particular, pickled food or processed food contains more salt, and a large amount of nitrite will be produced during its processing, which is easy to induce gastric cancer after long-term consumption.
7. Brain injury. American studies have found that too much salt in the daily diet will accelerate the deterioration of cognitive ability, leading to a decline in memory.
