Salt is in nearly every food consumed, but some may have a genetic variation causing them to have salt sensitivities. Salt sensitivity is estimated to be present in 51% of the hypertensive (high blood pressure) population. The ACE and AGT genes are both apart of the Renin-Angiotensin System (RAS). The ACE gene codes for the angiotensin-converting enzyme and is part of the RAS. This system controls the blood pressure by regulating the specific volume of fluids in the body.
