What is Salt/Sodium, and Why it is important for IgAN Patients

Sodium is a mineral that keeps the right amount of fluid in our bodies, controls our blood pressure, and helps our nerves and muscles function. However, too much sodium can cause problems. The most common form of sodium is salt. Salt is found in many of the foods we eat. Too much sodium can increase blood pressure and swelling. 

Guidelines for Salt/Sodium Restrictions

The general guideline limits sodium to <2300mg daily (1). Some people will be asked to limit their sodium intake to 1500-2300mg daily. Generally, people with IgAN are advised to limit their sodium intake. Here are some tips to help. 

  • Read food labels: Look at the nutrition facts on packaged foods. Check the “sodium” amount. Choose foods with lower sodium.
  • Cook at home more often: Restaurant food and fast food usually have a lot of salt. When you cook at home, you control how much salt goes in.
  • Use herbs and spices: Instead of adding salt, use herbs and spices to flavor your food.
  • Avoid processed foods: Things like chips, bread, wraps, canned soups, and deli meats are often high in sodium.
  • Choose natural, low-sodium foods: Fresh fruits, vegetables, and lean meats are naturally low in sodium.

Practical Tips for Reducing Salt in Your Diet (2)

  • Add veggies and fruits to your meals: Aim to fill half of your plate with these foods as they are naturally low in sodium.
  • Buy no-salt-added canned goods: when you cannot find low sodium canned options, make sure to rinse canned foods. 
  • Use herbs and spices: Try basil, oregano, garlic powder, or pepper instead of salt.
  • Avoid salty snacks: Have low-sodium snacks quickly on hand at home, like unsalted nuts, fruits, or unsalted tortilla chips.
  • Plan meals: Planning your meals ahead of time helps you choose fresh, whole foods and avoid last-minute, salty options.
  • Read nutrition labels: Check every label! Sodium can be hidden in unexpected places.
