Document Details : Title: Salt, the kidneys, and arterial hypertension Author(s): KRZESINSKI JM, COHEN EP Journal: Acta Clinica Belgica Volume: 62 Issue: 5 Date: 2007 Pages: 348-357 DOI: 10.2143/ACB.62.5.1002656 Abstract : The kidneys play a major role in the regulation of the salt balance and thereby regulate blood pressure. Salt sensitivity is acquired or genetically-induced and is noted in about 50% of patients with essential hypertension. This property leads to a high cardiovascular risk. In this situation, the benefit of salt restriction is significant, and this dietary change should be associated with a high potassium intake. In patients treated by antihypertensive drugs, salt restriction improves the blood pressure control, which can permit a reduction of the number of drugs required to achieve a normal blood pressure. The recommended maximal salt intake should not exceed 6 grams/day (NaCl). Because most dietary salt comes from processed foods, the help of the food industry is crucial for a long-term compliance with a reduced salt intake, which could yield an additional important benefit in the reduction of cardiovascular risk. |
