Myth #5: Too much salt causes high blood pressure
Reality: Perhaps, but too little potassium causes high blood pressure too

Large-scale scientific reviews have determined there's no reason for people withnormal blood pressure to restrict their sodium intake. Now, if you already have high blood pressure, you may be "salt sensitive." As a result, reducing the amount of salt you eat could be helpful. However, people with high blood pressure who don't want to lower their salt intake can simply consume more potassium-containing foods—it's really the balance of the two minerals that matters. In fact, Dutch researchers determined that a low potassium intake has the same impact on your blood pressure as high salt consumption does. And it turns out, the average person consumes 3,100 milligrams (mg) of potassium a day—1,600 mg less than recommended.

Put the Truth to Work for You: Strive for a potassium-rich diet—which you can achieve by eating a wide variety of fruits, vegetables, and legumes—and your salt intake won't matter as much. For instance, spinach, broccoli, bananas, white potatoes, and most types of beans each contain more than 400 mg potassium per serving.
