During the study, three groups of studies using computer simulations and models to quantify the benefits of three different strategies for salt reduction.
In one model, the researchers examined the effect of gradually reducing salt intake by 40 percent over the 10 years to 2200 milligrams per day, or approximately one teaspoon. In the second scenario, the researchers calculated the direct impact of reducing sodium intake by 40 percent. For the third model, the researchers examined the direct benefits of cutting salt intake to 1,500 mg per day, about half a teaspoon, as quoted by FoxNews.
The researchers found that by gradually lowering salt intake by 40 percent over the past 10 years could save 280-500 thousand lives. But if people cut their salt intake about 60 percent, more lives are approximately 500 -850 thousand will be saved.
Eating too much salt give you opportunities for developing hypertension, or high blood pressure, which in turn increases the risk of heart attack and stroke. That’s why reducing salt intake can prolong life because it can prevent many deadly diseases.
