With seawater, there is a hotbed of survival. As we all know, life on earth originated from the ocean. As a primitive unicellular organism, seawater naturally becomes body fluid when it forms organisms, and the sodium content in seawater is high. Therefore, in the gradual evolution of life, sodium becomes more and more important and becomes an indispensable part of organisms.
When salt comes into people's lives, people put salt into ingredients and find that ingredients are more delicious than before. When salt comes into people's lives, people put salt into ingredients and find that ingredients are more delicious than before. At this time, people's demand for salt is increasing with the passage of time. In other words, people's tastes are getting heavier and heavier, and some people can't adapt to light food all year round.
But in fact, people only need to eat about 5 grams of salt every day, which is enough to maintain normal health (probably the beer bottle cap is slowly closed, and then they can eat three meals on average). Excessive salt intake is not only bad, but also easy to cause diseases.
All living things on the earth need salt (specifically sodium), but different animals have different metabolic rates and different food habits, so wild animals can get the sodium they need from their own food. However, after human hair degenerates, the metabolism increases, coupled with the change of eating habits (from raw food to cooked food), so that the sodium metabolism in the human body exceeds supplementation.
In fact, we will find that the reason why we eat salt is to maintain our metabolism. In fact, we will find that the reason why we eat salt is also to maintain the needs of metabolism. It is precisely because of this that we need to eat salt, and human taste is particularly developed. If the salt is not enough, it will also affect the taste of food, so it is not impossible for us not to eat salt for a day, but to meet the needs of the body.
As a result, it will be found that it is basically unnecessary to eat salt to make an animal, because they have found foods with high salt content as substitutes in nature, and they should be special animals, and they will also obtain the salt components in nature according to the moss on the rock surface. Compared with humans, the biological clock is definitely salty, and it is also to help the body regulate endocrine.
For herbivores, they usually get salt from plants or salt water in salt marshes. For herbivores, they usually get salt from plants or salt water in salt marshes, while carnivores usually get salt from the flesh and blood of hunted animals. Some animals even get salt by licking saline soil, but animals need less salt than humans.
Because human beings are creatures with a strong sense of taste, tasteless food is difficult to swallow without salt, while animals have a slow sense of taste, so long as they eat enough salt, they can maintain their normal physiological needs.
Salt plays a very important role in maintaining the acid-base balance of animal body fluids, osmotic pressure of cells and body fluids, water metabolism and feed digestion, but animals, like people, can't eat too much salt, and even lead to salt poisoning.
Cells live in extracellular fluid, the main component of which is a salt solution. Cells live in extracellular fluid, the main component of which is a salt solution, and the main components are sodium and potassium ions. Their contents can show different osmotic pressures, especially the osmotic pressure difference between intracellular fluid and extracellular fluid, which can help nutrients to be transported into cells, while metabolic wastes in cells are discharged from cells.
Life on earth originated from the primitive ocean, and the environment in which our body cells live is also an inorganic salt solution, which is very similar to seawater. Some activities of the body may lead to the consumption of inorganic salts, which are essential for the normal state of the body and the intake of salt. Both humans and animals must do this, but humans are simple and direct, and animals can only take it through food or other ways.
