What Is a Low-Sodium Diet?
This food plan limits the amount of salt (sodium) that you take in. It is limited to no more than 2,300 mg (milligrams) per day. This is equal to about 1 teaspoon of table salt.
What Foods Are Highest in Sodium?
Sodium comes from more than just table salt. It may be sprinkled over a meal or added during cooking. However, most sodium comes from high sodium foods such as:
- Fast foods
- Preserved or processed foods
- Canned foods
- Frozen dinners
- Snack food
- Packaged starchy foods—like seasoned rice, instant mashed potatoes, macaroni and cheese
- Baking mixes
- Deli meats and cheeses
- Sausages and cured or smoked meats
Some simple swaps may help keep you at your daily sodium goal. Choose whole foods when possible. This includes fresh fruits and vegetables, and whole grains. Read package labels to see sodium levels. You may be surprised at where sodium can hide.
