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 and lead to edema (water retention). A high-sodium diet can also increase your risk of ]]>stroke]]> . Reducing your sodium intake can help:

  • Lower blood pressure
  • Reduce complications of ]]>heart failure]]> and kidney disease
