This is the Reason why Hypertension People are Prohibited from Eating Excess SaltWhen you eat too much salt, which contains sodium, your body holds extra water to "wash" the salt from your body. In some people, this can cause blood pressure to increase. Added water puts pressure on your heart and blood vessels.
Eating salt increases the amount of sodium in your bloodstream and damages the delicate balance, reducing your kidneys' ability to release water. The result is higher blood pressure because of extra fluid and extra pressure on the fine blood vessels that lead to the kidneys.
Salt intake is often regarded as one of the main factors behind high blood pressure. But the evidence supporting this idea is very weak, and eating less salt has a very marginal effect (and can sometimes be dangerous).
The proverb "Like vegetables without salt" turns out to be true for people who suffer from high blood pressure. In general, after a doctor diagnoses someone with hypertension, another word for high blood pressure, the doctor immediately advises you not to consume too much salt other than avoiding cigarettes and alcohol.
Surely you are wondering, what's wrong with salt? Why do people with hypertension have to reduce salt consumption in the daily menu? How dangerous is salt for the health of patients to the extent that doctors always forbid consuming these many kitchen spices. How do you actually use salt so that it can increase a person's blood pressure?
Properties of salt
Salt in sufficient quantities is really needed by the body. Salt or in its chemical language NaCl serves to release urine. Sodium is retaining fluid in the body before it will eventually be released into urine. Salt also helps the body to release sweat.
When excessive salt levels
When excess salt levels the body will try to neutralize it. That is by stimulating the brain to feel thirsty, thus encouraging humans to drink lots of water. Thus the volume of blood will increase because the nature of salt is binding on water, it will maintain water in the blood so that blood volume will increase.
Increased blood volume due to the high water content should be removed by the kidneys through urine. However, because salt is also, this water will be maintained by the body due to other salt properties, namely antidiuretic, which causes the kidneys to reabsorb most of the filtered water before being released into urine. The entry of large amounts of water into the blood vessels causes the volume of blood present in the circulatory system to increase.
If the blood volume increases automatically the blood flow will also increase. While the size of the blood vessels will remain. As a result there will be excessive blood pressure in the blood vessel wall which is the main cause of hypertension.
I eat a lot of salt, but how come it's normal?
Hypertension depends on talent. This means that each person has a specific anatomy of the body and their respective functions. Likewise with the body's response to salt. There are people who eat a lot of salt but their blood pressure is always normal. Conversely certain people will experience an increase in blood pressure even if they only consume a pinch of salt.
Therefore the term "people who are salt sensitive and salt resistant" appears. Salt sensitive people will experience a significant increase in blood pressure when in daily food contains a lot of salt. That doesn't apply to people who hold salt, where they will feel fine even though they eat a lot of salt.
Daily salt consumption limit
There are many versions in determining what limits are allowed in salt consumption every day for people who suffer from high blood pressure or who want to avoid this disease. However, the limit of salt consumption recommended by the American Heart Association is no more than 2,300 grams per day. That means that in a day you can eat salt no more than 1 teaspoon.
A study conducted by the Dietary Approaches to Stop Hypertension (DASH) in collaboration with U.S. The National Institutes of Health concludes that salt consumption is not more than 2,300 gr a day with foods that are low in fat, rich in potassium and calcium in patients with mild hypertension, will lower blood pressure with antihypertensive drugs.
You need to know, salt is not the main cause of hypertension. Limiting salt intake in an effort to avoid hypertension will be more effective if it is coupled with adequate exercise, not smoking, reducing staying up, avoiding obesity and maintaining blood cholesterol.
