How much is 5g salt?
Recently, researchers surveyed 2657 people around the age of 60. The results showed that the high sodium diet group with daily sodium intake of more than 4g (10g salt) was significantly higher than the low sodium diet group with daily sodium intake of less than 1g (4g salt). Moreover, the high sodium diet group suffered from hypertension, and the daily sodium intake increased by 0.5. Therefore, the researchers concluded that high salt intake would increase the risk of hypertension.
