Flavorful Ways to Reduce Sodium in a CKD Diet

A low-sodium diet is essential for individuals with Chronic Kidney Disease (CKD), as damaged kidneys cannot effectively eliminate excess sodium and fluid. This buildup can lead to fluid retention and high blood pressure, resulting in further progression of CKD. Worry about sacrificing the taste of food? The good news is there are plenty of flavourful ways to enjoy meals while keeping sodium in check. [1]

Recommended sodium intake for CKD patient: <2400mg/day [2]

Cook it right, taste it bright

  • Steaming: Preserves nutrients 
  • Carmelization/Browning: Rich, deep flavour
  • Homemade Low-Sodium Broth: *avoid high potassium tomatoes

Reading labels, smart shopping

  • Know your daily sodium limit
  • Check nutrition labels: Compare the sodium content per serving with your daily limit.
  • Avoid products contains 240 mg or more sodium per serving
  • Compare similar products: Choose the one with the lowest sodium content for the same serving size
  • Prioritise products labeled as ‘sodium-free,’ ‘very low,’ ‘low,’ ‘lower,’ or ‘reduced sodium’

Dining out smartly

Eating out is always challenging to control sodium intake as many restaurant and hawker foods are prepared with high-sodium ingredients like sauces, seasoning powders, and processed items, making it difficult to estimate or limit your intake. Here are some tips to help you make healthier, lower-sodium choices when dining out: [2,4] 

  • Watch for hidden sodium: belacan, budu, tempoyak, cincalok, sambal, gravy/sauces (kuah)
  • Avoid processed and cured food such as bacon, sausage and ham
  • Make special request for your meal to be prepared without added salt, MSG, or seasoning powders, and ask for sauces, gravies, and condiments to be served on the side
