The harm of excessive salt to human body

Salt is one of the essential seasonings in people's kitchens, because no matter what kind of dishes are cooked, salt is essential. However, it should be noted that although salt can improve the taste of food, if excessive salt is consumed for a long time, it will have a great impact on human health. Below, I will introduce to you in detail the dangers of excessive salt consumption!

1. Increased risk of respiratory infections

Large amounts of salt entering the human body will inhibit the activity of respiratory cells and reduce oral saliva secretion. Greatly reduces the disease resistance of the respiratory system and increases the chances of viral and bacterial infections in the respiratory tract. The most typical manifestation is persistent cold symptoms.

2. Cause freckles to grow

Adding too much salt when cooking, especially at night, will lead to a significant increase in the body's demand for water. The human body's ability to absorb water is very poor during sleep, and salt will cause this ability to continue to decline. When water cannot be absorbed, the body will experience edema. Generally, when women suffer from edema, freckles will grow on their faces.

3. Cause osteoporosis

Eating too much sodium salt will cause the sodium ions contained in the sodium salt to be deposited in the human body. Sodium ions and calcium ions have a repulsive reaction. Excessive sodium ions will promote the excretion of calcium ions from the body. At the same time, sodium ions will stimulate the parathyroid glands, increase the secretion of parathyroid hormone, thereby activating adenylate cyclase on the osteoclast membrane and destroying the dynamic balance of bone metabolism. The loss of calcium in the human body and the disruption of bone metabolism balance are the main culprits leading to osteoporosis.

4. Cause gastritis

Excessive consumption of salt can damage the gastric mucosa, leading to gastritis and even gastric cancer. Scientific experiments have shown that a large amount of salt entering the stomach will cause diffuse congestion, edema, erosion, bleeding and necrosis of the gastric mucosa, making the gastric mucosa susceptible to damage and causing gastritis or gastric ulcers.

4. Induce asthma

A high-salt diet can cause changes in the permeability of the glomeruli, increasing the burden on the kidneys. Excessive salt intake can also increase the responsiveness of bronchial smooth muscles, thereby exacerbating the occurrence of asthma.

5. Aggravate diabetes

The sodium content in food has a direct relationship with starch digestion, absorption rate and blood sugar response. Salt can accelerate the digestion of starch by stimulating the activity of amylase and accelerate the absorption of glucose released by digestion in the small intestine. People with diabetes and those at risk of developing diabetes should limit their salt intake in their lives.
