What happens if you eat too much salt, and what happens if you eat less?

Eating too much causes cancer, and eating less is dehydrated.

In life, there is a seasoning that each of us cannot live without, and that is salt. However, due to long-term heavy diets, most people actually have excessive salt intake. Long-term high-salt diet has many effects on the body and also increases the risk of many diseases.

When the body is deficient in salt, there will be weakness in the limbs, vomiting, muscle spasms, and collapse, and a long-term salt-free diet will destroy kidney function and cause proteinuria. Salt deficiency in the human body is one of the causes of kidney failure.

What are the dangers of eating too much salt?

Too much salt can increase the burden on the kidneys and cause edema. Although everyone's taste is different, and each meal may be salty, the salt concentration in the human body is always stable within a certain range under the regulation of the kidneys. If the intake of salt exceeds the required amount for a long time, especially when the kidney function is reduced, the kidneys will not be able to excrete salt according to the body's needs, and the excess salt will accumulate in the tissues, and the tissues will absorb water to dilute in order to maintain osmotic balance, resulting in the retention of water and sodium salts, and the patient will have edema symptoms.

Therefore, people with kidney disease need to severely limit their salt intake.

Eating too much salt can cause high blood pressure. Comparing Japanese and Eskimos, the prevalence of hypertension is low among Eskimos who eat less salt, while the prevalence of hypertension is high among residents of northern Japan who consume up to 20 grams of salt per day. Studies have shown a linear relationship between sodium intake and the prevalence of hypertension, meaning that the more salt you eat, the higher your blood pressure is likely to be.

This is due to the retention of water and sodium salts in the body, which leads to swelling of vascular smooth muscles, thinning of the lumen, and increased vascular resistance, thereby increasing blood pressure; At the same time, the increase in blood volume and the increase in the amount and output of blood return to the heart increase the burden on the heart and kidneys, which can further cause an increase in blood pressure.

In addition to kidney disease and high blood pressure, arteriosclerosis, coronary heart disease, gastritis, and stomach cancer may all be associated with eating too much salt. Because sodium can promote blood circulation, increase cardiac output, and directly increase the burden on the heart, a high-salt diet is not good for coronary patients with insufficient cardiac blood flow**. Due to the high osmotic pressure of table salt, excessive high-salt food can also cause direct damage to the gastric mucosa, leading to gastritis, gastric ulcer, and even inducing cancer.

Dry mouth and thirst. The impact on people is not very great.

Over time, it can induce high blood pressure.

It seems to cause high blood pressure. This is especially true for pregnant women and babies up to one year old.
