In popular thought, disputing sodium's link to high blood pressure is equivalent to questioning whether the earth is round. However, some experts now believe that salt will not raise blood pressure in everyone, just in people who are "salt sensitive." Only 10 percent of the population is salt sensitive, according to BioMarkers by Professor William Evans and Dr. Irwin H. Rosenberg.

Of course, far more than 10 percent of us suffer from hypertension, meaning that if these experts are correct, salt intake cannot be the only factor contributing to America's high blood pressure epidemic. In fact, according to Gayle Reichler's book, Active Wellness, only half the people with hypertension have high blood pressure because of their salt intake, making cutting down on the amount of salt you eat a good step toward lower blood pressure, but not a cure-all.

Scientists are still unsure why some people's bodies respond to salt more drastically than others; however, most theories focus on sodium's in vivo interaction with potassium, magnesium and calcium. In fact, some experts believe that these nutrients play more of a role in these individuals' salt sensitivity than sodium itself. Deficiencies in these complementary minerals may actually be the larger culprit in hypertension. Read more…
