Effect of oral salt loading on blood pressure and lymphocyte sodium metabolism in borderline hypertension.
A randomized double-blind cross-over trial was performed to test the effects of oral salt loading (normal diet + 200 mmol NaCl/day for 4 weeks followed by normal diet + 400 mmol/day for 1 week) against placebo on blood pressure and lymphocyte sodium homeostasis in 10 young borderline hypertensive men, genetically predisposed for essential hypertension. Salt loading caused no significant changes in blood pressure levels, lymphocyte sodium content and efflux. In conclusion, our subjects seem insensitive to a few weeks of excessive salt intake.
