What Is a Low-Sodium Diet?

A low-sodium diet restricts the amount of sodium (salt) in your diet. On this diet, you should aim to consume no more than 2,300 milligrams (mg) of sodium per day. This is the amount in about one teaspoon of table salt.

Sodium is a mineral found in many foods. Most people consume much more sodium than they need. Diets high in sodium can increase blood pressure. A high-sodium diet may increase your risk of stroke . Reducing your sodium intake may help lower blood pressure.
