For example, one teaspoon of salt consists of 2,300 mg of sodium. When following a low sodium diet, foods with high sodium must be reduced or completely avoid to keep the sodium consumption under the suggested level.
How Much Is Too Much?
It is important to know that how much salt is safe for consumption. The American-Heart Association suggests a limit of 1,500 mg every day. The FDA suggested a limit of 2,300 mg of sodium every day. The US dietary guidelines used to suggest a limit of 1500 mg every day for people of 51 age, and ailments like kidney disease, blood pressure, and diabetes. But now it is changed to 1500mg every day only for the individual with high blood pressure and 2,300 mg for all.
Reasons for Low Sodium Diet
Low sodium diets are some of the most used diets in hospitals. It is because research indicates that limiting sodium may help to improve or control medical conditions.
Kidney diseases like chronic kidney failure or kidney disease negatively affect kidney function. When your kidneys are compromised, they are not able to effectively release extra sodium or fluid from the body. If fluid and sodium levels become higher, pressure develops in the blood, which can cause further damage to already affected kidneys.
For these reasons, the National-Kidney-Foundation suggests that all people with CKD restrict their sodium consumption to lower than 2gm than 2,000 mg every day (Source).
High Blood Pressure
High blood pressure is one of the risk factors for different conditions, including stroke and heart disease. A high sodium diet has been connected to raised blood pressure.

Various studies have shown that lowering salt consumption may help to reduce high blood pressure in people with raised levels.
According to a review of 6-studies in more than 3,000 people, limited salt lowers the blood pressure in adults with a powerful effect observed in those with high blood pressure.
Salt sensitivity of people with high blood pressure varies widely and certain subgroups like American, African tend to be highly affected by a high salt diet.
Low sodium diets are generally suggested to people with heart problems.
When the heart is compromised, kidney functions begin to decline, which can cause water and sodium retention.
Eating high salt could cause fluid overload in individuals with heart failure and lead to risky complications, such as breath shortness. Regulatory agencies suggest that individuals with mild heart failure reduce their sodium consumption to 3,000 mg every day while those with medium to severe heart failure should lower their consumption by no more than 2,000 mg every day.
However, according to many types of research low sodium diets help those with heart malfunction, others have remarked that no restriction diets contribute to better results. For example, a study in 833 people with heart failure discovered that a sodium-restricted diet with lower than 2,500 mg every day was linked with a significantly higher risk of death or hospitalization than unrestricted sodium diets with 2,500 mg or more every day.
