Sodium is also called salt.
What Is Sodium?
Table salt is a combination of two minerals – sodium and chloride.
What Does Sodium Do to Your Body?
Your body needs some sodium to work properly. It helps with the function of nerves and muscles. It also helps to keep the right balance of fluids in your body.
Why Is Too Much Sodium Bad for You?
Your kidneys control how much sodium is in your body. If you have too much and your kidneys can’t get rid it, sodium builds up in your blood. This can lead to high blood pressure.
High blood pressure can lead to other health problems.
How Much Sodium Should You Have a Day?
Most people in the U.S. get more sodium in their diets than they need. A key to healthy eating is choosing foods low in sodium.
The Dietary Guidelines recommend that most adults eat less than 2.3 grams per day. That equals about 1 teaspoon of table salt a day.
Some people are more sensitive to the effects of salt than others and should eat less. This includes people who:
- Have high blood pressure
- Have diabetes
- Have kidney problems
- Are African American
- Are over age 50
How Do You Know How Much Sodium Is in Food?
Reading food labels can help you see how much sodium is in prepared foods.
