Is salt unhealthy?

20 18 18 American scientists published papers in the well-known academic journal nature, and studied mice fed with high salt. The results show that high-salt diet may lead to brain development, cognitive impairment and slow response. Mainly because salt enters the intestine after intake, and the intestine communicates with the brain through the brain-intestine axis. High-salt eating habits easily affect the normal development of the brain, leading to mental decline and slow response.

Although the research object is mice, which is quite different from human beings, and the salt intake is 8- 16 times higher than that of daily diet, it is hard to say whether the conclusion can also be applied to humans. However, it is undeniable that high salt and sodium do cause some diseases.

Salt is a very important condiment in our daily life. If there is no salt, food will have no taste. Like hot pot, barbecue, smoking and so on all depend on salt to a great extent. However, if the intake of salt is too much, it is easy to produce edema and rough skin, increase the risk of chronic diseases such as hypertension, arteriosclerosis, gastric cancer, kidney disease and osteoporosis, and bring serious harm to the body. According to the dietary guidelines of China residents, the daily salt intake of each person is less than 6 grams, which includes not only the salt in the daily diet, but also the salt intake in biscuits, potato chips and other processed foods. How to reduce the daily salt intake?

1, select low sodium salt. The main component of salt is sodium chloride, and the low sodium salt contains about 70% sodium chloride and 30% potassium chloride. If you choose to consume the same weight of low sodium salt, it will reduce the sodium ion intake by about 30%. The most important thing is that the salty taste of low-sodium salt is not much different from that of ordinary refined salt, and the effect of reducing sodium and supplementing potassium can be achieved without reducing salt.

2. Switch to other seasonings. Add some pepper, pepper, pepper and other seasonings to increase flavor instead of salt.

3. Change the way you eat salt. Use a spoon to take salt, and when putting salt-containing condiments such as soy sauce, dip it in, and don't pour it all at once.

4. Put salt before cooking. Putting salt before taking out the pot can prevent the salt from becoming weak during heating, thus avoiding releasing more salt to some extent.

5. Reject invisible salt. In addition to putting less salt in daily cooking, we should also reduce pickled and smoked foods such as pickles and bacon. In addition, snacks such as potato chips and candied fruit also contain a lot of invisible salt, so these foods should not be eaten more.
