High sodium intake (>5 g/d) increases cardiovascular risk primarily in individuals with hypertension, whereas in normotensive individuals, the risk increase is less prominent or occurs only at much higher levels.

If you have high blood pressure, keeping your sodium intake below 5 grams per day is crucial to avoid increased cardiovascular risk. For those with normal blood pressure, the risk from high sodium may be lower, but moderation is still advised.
