people live on food. Everyone needs to eat food every day to provide nutrition and energy to the body, so as to maintain the normal physiological activities of the body. In addition to these two typical cuisines, most of the eating habits in southwest and central China are mainly salty. Let’s take a look with you.
But too much salt, okay? We can tell you a positive answer. Whether for people with chronic diseases or healthy people, limiting salt consumption is more conducive to the body to control blood pressure and prevent gastrointestinal diseases and cardiovascular and cerebrovascular diseases.
but why do some people say that regular low salt diet will affect gastrointestinal digestion? The reason is that whenever we eat food, gastric acid will be secreted. It can be used as a raw material for salt. Eating salt can also make the intestines and stomach digest normally. If it is a low sodium diet, it will destroy the environment. People often suffer from dehydration under high temperature, especially if they keep their diet low.
in fact, this idea is wrong. The main component of gastric acid in the stomach is hydrochloric acid. Although the component of salt is sodium chloride, it can maintain a person’s normal physiological activities. When eaten in an appropriate amount, it can promote appetite and maintain a person’s physical strength. According to its physiological function, salt can also help us maintain the acid-base balance in the body and promote the secretion of digestive juice.
for people in large salt countries in China, it is almost difficult to have too much salt loss due to excessive sweat loss, resulting in salt induced heatstroke. Moreover, eating an appropriate amount of salt will be beneficial to gastrointestinal health. Especially for people with poor stomach digestion, the amount of salt they eat can be controlled to less than 6G every day, which will not bring trouble to their health.
therefore, we should no longer believe the rumor that regular low salt diet is easy to affect gastrointestinal digestion. Most people are suitable to eat like this.
in addition, the low sodium salt sold on the market is actually more suitable for patients with hypertension. Compared with ordinary table salt, some of the sodium is still 35% higher than potassium. Hypertension
argument 1: gastric acid uses salt as raw material. Can salt promote digestion?
the production of gastric acid requires salt. Without salt, the main cells in the stomach cannot produce gastric acid. If there is not enough stomach acid, reflux will occur.
[truth]
the main component of gastric acid is hydrogen chloride. Many daily foods contain chlorine, & ldquo; No stomach acid without salt & rdquo; My statement is not accurate. On the other hand, gastric acid is not secreted by salt intake. The data show that after the human body ingests food, the expanding effect of food on the stomach jointly stimulates the vagus nerve in the stomach and a series of cells on the gastric wall, prompting the secretory vesicles on the gastric wall to secrete gastric acid.
therefore, it is a fallacy that salt is necessary for the production of gastric acid, and the argument that eating salt promotes digestion is untenable.
Argument 2: in the heat stroke in Chicago, low salt diet caused 750 deaths?
experts in the video said that in 1995, there was an extreme high-end weather in Chicago for two weeks. When heatstroke patients are sent to hospital, doctors will give them normal saline. However, 750 people died from the high temperature, mostly the elderly who have been strictly following a low salt diet.
[truth]
in fact, there is no evidence that low salt diet will lead to heatstroke, and the emergency measures after heatstroke have little to do with daily diet. Zhang Jing pointed out that heatstroke refers to a series of symptoms caused by sweat gland failure and excessive electrolyte loss under high temperature. In terms of treatment, intravenous infusion of normal saline is a formal medical operation to save patients with severe heatstroke, and electrolytes other than salt should be supplemented according to the loss of electrolytes. Blindly emphasize & ldquo; Salt & rdquo; It is not correct to prevent and treat heatstroke.
data show that there was & ldquo; Chicago heatstroke & rdquo; The incident resulted in 750 deaths. According to the verification of relevant experts, the main reason is that the body regulation function of the elderly is poor and there is no condition to use cooling equipment. It is impossible to conclude that these people are people who strictly implement a low salt diet. The statement given by the expert in the video is obviously groundless.
