Do you know the importance of salt to people?

In addition to increasing blood pressure and indirectly accelerating the risk of arteriosclerosis and cardiovascular disease, salt intake has also been found in people without high blood pressure to directly affect the function of blood vessels. ‍‍

If high blood pressure is not controlled in a timely and effective manner, the three important vital organs of the heart, brain and kidneys will be fatally hit, resulting in serious complications, such as hypertensive heart disease and coronary heart disease.

A low-salt diet is very beneficial for people with high blood pressure, but not everyone needs a low-salt diet. Patients with kidney disease, chronic gastric disease, and osteoporosis should limit their salt intake, and it is advisable to eat less salt. ‍‍

Salt restriction is healthy, but it's not better to be healthier without salt. Because the composition of table salt is sodium chloride, sodium can maintain the body's osmotic pressure and acid-base balance, and chloride ions are also involved in the production of gastric acid, which helps digestion, which are extremely important minerals.

Therefore, advocating a light and low-salt diet can avoid excessive loss of urinary calcium, prevent osteoporosis, and also help prevent and treat hypertension. Therefore, a low intake of salt can ensure good health to a certain extent.

Of course, less salt is better, but in nutrition, low salt is not simply "eat less salt", and light taste is not necessarily the same as "low salt". And, not everyone needs a low-salt diet.

First of all, we should take total control of salt intake every day, measure it with a measuring tool, and add it according to the amount of each meal. If sodium-rich foods are added, salt intake should be reduced accordingly. ‍‍

Salt is really important to people, and in nutrition, a low-salt diet is very popular. Long-term heavy food consumption can easily lead to a series of physical health problems. ‍‍
