Salt has been around long enough, longer than some of us have been around, our parents, grandparents, great grandparents or even ancestors. There is so much that has been said about salt that a lot of people do not know about, yet we still end up using salt in the kitchen oblivious to the important facts about it. Why is it that we keep using salt from time to time without caring to learn something useful about it? Salt is important of course to our diet, and to the meals that we prepare. In as much as to most of us salt is just another component that we use to make sure that our food is sweet, salt has a lot more benefits than most of us can conceive.

Basically salt is one of the nutrients that the body needs because it is not able to manufacture sodium and chloride on its own. Therefore the only way through which you can be able to get these minerals into the body is through eating salt, at least in the right amounts and proportions. As a matter of fact the body does have a special receptor just for salt in the digestive system, and this is one of the common components of taste. As an electrolyte salt has a minute charge. When it comes to the issue of using salt as a preservative, its action is rather basic. Salt generally makes life harder for microorganisms to survive and this is how preservation works. When you sprinkle salt on to these microorganisms, salt will simply drain any of the water that is available in their cells. In the process the microorganisms will be dehydrated and die off naturally, keeping the food well preserved.

Besides preservation salt also has the special role inside the body of making sure that the blood pressure and volume are balanced. Salt and blood pressure have coexisted in a peaceful relationship from as early as the time when salt was first discovered, more than 4000 years back. According to scientific research, when you increase or decrease the level of salt that you take on a daily basis, this can have an impact on your blood pressure especially if you are the kind of individual who is sensitive to salt. Therefore this is why those who have issues with their blood pressure are normally advised to be cautious when it comes to their salt intake or their intake of foods that are rich in the salt content.

Once it is inside the body salt will basically turn into an ion pump. Its action inside the body is more or less the same way that it acts on microorganisms outside the body. It makes it harder for dangerous microorganisms to survive inside the body system. Within the body it controls the water balance inside the body system, and this is why electrolytes are considered to be an important part of the human body system. However, it is important to also take note of the fact that too much salt is dangerous to the body.
