The best cold cereal for kidney disease is a question that comes up for my patients for a number of reasons. It can be a great low protein breakfast option or snack when it feels like they can’t eat anything else. Kidney disease (CKD) is a complex condition and it can feel like food options are limited. 

Low FODMAP Breakfast Cereal

How do you choose the best cold cereal? 

Choosing the best cold cereal for kidney disease is not necessarily a straightforward question though. It depends on the person. The nutritional considerations for the cereal include:

  • sodium
  • protein
  • phosphorus
  • potassium


For most of my clients, I’m going to recommend low sodium options. Across the board, if you have kidney disease, a low sodium diet is recommended. 1500-1800 mg of sodium per day is appropriate for most patients with CKD. That being said, most cold cereals are relatively low in sodium, as I would consider under 300 mg per serving to be decent. If you are having trouble with your sodium intake, you may want to opt for something with less than 180 mg. Some cereals like Post Original Shredded Wheat and Kashi Organic Cinnamon Harvest have 0 mg of sodium. 


Protein is a nutrient that needs to be limited when it comes to CKD (non-dialysis). The more protein you consume, the harder your kidneys have to work to excrete the byproducts urea and nitrogen. I like to recommend cold cereal as a breakfast or snack option because it is low in protein. I don’t usually recommend products that are fortified in protein like Premier Protein cereal or Magic Spoon. I also recommend using a plant-based milk like almond milk to reduce protein. While protein is necessary for our bodies to function, ask your doctor or dietitian how much protein is right for you. 


Another nutrient that can be a concern is phosphorus. If you have elevated phosphorus in your labs, I first suggest reducing phosphorus additives from your diet. We absorb much more phosphorus from additives than we do from naturally occurring phosphorus. Phosphorus additives would be listed on the ingredient label as any word containing “phos”, like trisodium phosphate.  If phosphorus continues to be a problem, then you may need to limit naturally occurring phosphorus in foods like nuts, bran, and oats (thus affecting your cereal options). 

Some individuals don’t have elevated phosphorus in their labs, so I’m less concerned about phosphorus for them, but it does not hurt to limit foods with phosphorus additives in general. 

Cereals that have “phos” in the ingredient label: Frosted Flakes, Lucky Charms, Rice Krispies, Reese’s Puffs, Oreo O’s, Cinnamon Toast Crunch, Cheerios, Life Cereal 


Potassium (K) is a confusing mineral when it comes to CKD. Oftentimes, people are told they have to limit all high potassium foods. However, you only need to limit potassium if you have high potassium in your bloodwork. In fact, potassium can actually be beneficial for your blood pressure, so if there is no need to limit potassium (ie high potassium in blood work), then incorporating it could be health-promoting. 

High Potassium Cereals (more than 200 mg K) 

  • Kellogg’s Raisin Bran (280 mg K)
  • Kashi GO Crunch (350 mg K)
  • Grape Nuts (260 mg K)
  • Kashi Autumn Wheat (200 mg K)
  • Post Shredded Wheat (250 mg K)
  • Post Bran Flakes (210 mg K)
  • Quaker Brown Sugar Oatmeal Squares (200 mg K)

What about low potassium cereals?

We’ll cover that in our “best cereal” list below.

How can I make cold cereal into a filling meal?

Cold cereal can be a great part of a renal friendly breakfast but it isn’t always satisfying enough for a meal. Choosing a higher fiber cereal will keep you fuller longer. If you have the option to add nuts or seeds, that can had fat and fiber to be more filling. You can also add fruit, but if your potassium is elevated, choose low potassium fruit like berries.
