Do I have to salt the food?
Argued that three tablespoons of salt - lethal dose for humans, capable to cause irreversible processes in his body.We can not say that, having used such amount of this product, you can die, but to harm the body, and quite serious, - it easily.And to avoid such disastrous consequences, it is necessary to know the normal dose of salt to it.It is considered that such a - 1 teaspoon of salt per day (about 11 grams of sodium chloride).In countries where the climate is much hotter and less humidity, sweating from local residents increased, the need for a daily dose of salt increases significantly, almost 2 times (25-30 grams per day).Well, now think about it, how many actually edible salt in the day you eat exactly.Most likely, this figure is significantly higher than the norm, and it may even be referred to as the lethal dose of salt on the condition that you suffer from any illness in which the product is contraindicated.In other words, the person in this case, just slowly kills himself by himself.By the way, have salt reduced calorie, it is close to zero.
Children's bodies and salt.Pregnancy and salt
We have found that salt is essential to the human body.She is involved in its metabolic processes and vital functions.Therefore, a child and a pregnant woman needs enough salt.But there is a small clarification:
- When streamlined breastfed baby with mother's milk fed the right amount of salt along with other nutrients and vitamins.Therefore, the first solid foods does not necessarily add some salt.Of course, with the growth of the child, with increasing demand for minerals in his food salt added need, but in moderate amounts.
- Pregnancy - a special state in which the body for nine months is responsible for the growth and development of the baby.Therefore, the need for salt in women interesting position is greatly increased.Of course, the measure is necessary to know, that is. E. In the event of the amount of alcohol to reduce the swelling of sodium chloride.But completely excluded from their daily diet salt to pregnant women prohibited.

How much salt is detrimental to an adult?
This question is raised by scientists and doctors around the world for many years, trying to find the exact answer.So, let's discuss how many spoons of salt - lethal dose for one person?After a day we eat it in large quantities.Still, to talk about grams of salt, which can harm the human body, and they are 3 g / kg body weight.That is, if the average person to eat the fourth part of a pack of salt (250 g), he will die.Yes it is.Especially if he did not use the proper amount of liquid.And ate it in one sitting.As soon as the pressure rises, there will be edema, pulmonary edema, and happen to the brain, in short, death is provided to you.
salt poisoning
Of course, in this case we are talking about the daily violation in the amount of consumed sodium chloride.People say that the 3 tablespoons of salt - lethal dose.But is it?It is difficult to apply this rule for each particular individual, because we all have different weights and growth, and the distribution of all common substances in the body of a single person is different.Therefore, scientists are inclined to believe that the lethal dose of salt for human - 3 g / kg body weight.These standards were prepared by carrying out the necessary experiments on rats.Of course, animals and humans is difficult to compare.Usually, the first of them is much easier poisoned salt, since it does not use the proper amount of water per day.This only worsens the current disastrous situation for their bodies.How to understand what is happening in the body when there gets too much salt?As soon as the pressure increases dramatically due to changes in blood composition.The person feels very bad.Comes dehydration, impaired nervous system.The result of the irreversible consequences: the death of the human body due to lack of revenue in its tissues and organs of the right amount of oxygen.
Sol as a habit, a deadly life
turns out that the statement "3 tablespoons salt - lethal dose" is not quite correct.Therefore, you must calculate the number specifically for themselves, based on their weight: 3 g per 1 kg of body weight.Get used to eat salt in moderation, and if overweight, edema, high blood pressure does not bother you.
Remember that in any case it is important to know when to stop.It concerns and the use of salt.It is very important for your body, it can be said is vital.But its use in excess eventually able to destroy human.
