Does Salt Cause High Blood Pressure Levels?

Virtually every doctor alive will tell you that if you want to lower your blood pressure, you need to limit the amount of salt you consume—and I’m no exception. That’s because salt promotes water retention, and excess water in the body causes high blood pressure levels.

How much should you cut back? More than you probably think. The average adult consumes the equivalent of nearly two teaspoons of salt a day. That’s practically two times the upper limit for good health!

Reversing High Blood Pressure Levels With Less Salt

Here are some things you need to know about salt consumption as you strive to lower your high blood pressure levels.

  • Don’t go cold turkey and eliminate all salt. Your body requires sodium (a component of salt) to regulate fluid balance and distribution, as well as nerve and muscle cell function. Although you need some sodium, the standard diet includes way too much.

  • Aim for less than 2.5 grams of sodium a day. Two important tips: Don’t use salt from a shaker, and read labels to add up the amount of salt you’re taking in. The majority of the excess salt we eat is hidden in processed foods, such as canned spaghetti sauces, soups and sauerkraut. For a full run-down, check out my list of salt-heavy foods.

  • Keep the proper sodium-potassium balance in mind. Sodium and potassium are essential for numerous biochemical processes in the body. However, whereas sodium increases water retention and drives up high blood pressure levels, potassium helps keep blood vessels relaxed and blood pressure low. For optimum health, you should consume sodium and potassium in a specific ratio. Strive to consume more potassium than sodium, with 3 grams of potassium your minimum daily goal. Learn more about the proper sodium-potassium balance.

  • Avoid fast food. Many fast-food menu items are high in salt, so you can easily exceed the recommended level with just one serving. For example, a flame-broiled chicken sandwich at a fast-food restaurant can contain 1,200–1,400 mg of sodium.

  • Make up for the reduced salt in your diet by cooking with fresh herbs and spices. Basil, garlic, oregano, rosemary, chives, parsley and onion are great sources of flavor, and all of them contain natural substances that are good for your health. Learn more about the four heart-healthy seasonings that I recommend to help lower blood pressure.
