title: [Salt restriction in people with hypertension and patients with cardiovascular disease : meaningfulness and extent].
abstract: The association between high salt (NaCl) intake and increased blood pressure has been demonstrated in a multitude of studies. Clear evidence for a blood pressure lowering effect of a reduction in dietary NaCl has also been reported. In contrast to the antihypertensive effect of NaCl reduction, from a clinical scientific perspective a positive effect on cardiovascular mortality has not been sufficiently demonstrated. Often the proven blood pressure lowering effect of reduced NaCl intake was extrapolated to an effect on the cardiovascular risk. This article describes the current data situation and discusses the effects of NaCl restriction in people with hypertension and patients with cardiovascular diseases in detail.
  
  
  CONCLUSIONS
  moderate restriction of NaCl to 6 g/day is recommended for patients with hypertension or cardiovascular comorbidities, intensive reduction to ≤3 g/day is not recommended and for patients with few comorbidities an NaCl intake of up to 10 g/day has no obvious disadvantages.
