Salt and High Blood Pressure

By

Updated April 09, 2014

How Salt Affects Blood Pressure:

Salt (sodium) is essential to our bodies. Normally the kidneys control the level of salt. If there is too much salt, the kidneys pass it into urine. But when our salt intake levels are very high, the kidneys cannot keep up and the salt ends up in our bloodstream. Salt attracts water. When there is too much salt in the blood, the salt draws more water into the blood. More water increases the volume of blood which raises blood pressure.

Salt Sensitivity:

Some people are more sensitive to salt than others. In some people too much salt will cause their blood pressures to rise, in others there will not be as large a change. About half of people are salt sensitive. African-Americans, the elderly and people with diabetes are more often salt sensitive. If you have high blood pressure, you can always benefits from decreasing your salt intake.

The Salt Intake Recommendations:

You need about 500 milligrams of salt everyday for your body to function. Most people take in about 10 times that amount daily. The recommended amount of salt for people with high blood pressure is about 1500 milligrams a day. Any reduction in your salt intake will help.

Lowering Your Salt Intake:

Processed foods use salt as an additive. Almost 80% of the average person's daily salt intake comes from processed foods. If we ate only natural foods and limited the use of table salt, we would be able to eliminate excess salt in our diets.

Foods to Avoid:

Salt can hide in many processed foods. Try to eat mostly produce, fruits and fresh meat. Avoid condiments, pickles, ham, bacon, salsa, cheese, cold cuts, olives, broths, anything canned, and anything processed. The list can go on and on. You need to check the sodium content on food labels and think twice about anything with over 100 mg per serving. A few of these items are okay everyday, but not too many.
