A recent study showed that not only did cutting dietary sodium reduce blood pressure in those with existing hypertension, it also reduced blood pressure in people who were not yet at risk.
What's the leading cause of heart disease? High blood pressure, which is often triggered by high sodium intake in the food we eat. Hypertension is also the leading cause of stroke, heart failure and kidney disease. Yet even if we never salted another dish again in our lives, we would likely still be eating too much sodium every day. That's because it's added to manufactured foods for flavor, texture and color as well as a preservative.
That's especially significant considering the revised guidelines from the American Heart Association, Fergus said. Hypertension used to be diagnosed when the top number was 140 and the bottom number was 90. Now you're considered hypertensive if your blood pressure is 130/80."At 130/90 you already begin to see changes in the vasculature of the kidneys and some hardening of the arteries," Fergus said."So having blood pressure in the lower range is beneficial.
