What is the Best Cereal for Kidney Disease?

Sharing is caring!

Are you looking for a satisfying breakfast that is quick and easy, full of nutrition to give you energy for the day? Maybe you just need something to eat in order to take your morning medications or a little something before you head out the door for dialysis treatment. Then cereal may be a great option for you! But you may be wondering what is the best cereal for kidney disease. 

Why breakfast is important?

We’ve all heard that breakfast it the most important meal of the day. It breaks the fast that your body has gone though while you were sleeping for several hours and provides the initial nutrition your body will use to get started for the day.

Why cereal is a good option for breakfast?

Many of my patients and clients tell me they aren’t big breakfast eaters. They can’t eat very much before coming to dialysis treatment or just don’t have the time to make a large breakfast in the morning before going to work or doctor appointments.

In these cases, cereal makes a great option for people with kidney disease. It is quick and easy to make, very little cooking or prep is required, and there are various options to choose from.

It is important to know what to look for on the food label to help you decide if a particular cereal is the best cereal for kidney disease. Cereal doesn’t have to be limited to just breakfast, it also makes a great option for a healthy snack too!

What to look for on the food label?

So what do you need to look for on the food label to determine if it is the best cereal for kidney disease?

Serving size

Serving size is important because it determines how much nutrients you will consume in that particular portion. If you have more than the suggested serving size, then you will have more of the listed nutrients provided on the food label.

Serving sizes for cereal can vary greatly depending on the type of cereal and if it needs to be cooked or ready to eat.

I recommend measuring out the suggested serving size a couple of times in the same bowl. Then eventually you will be able to eye-ball it and have an idea what the serving size actually looks like in your cereal bowl.

You may need to go back and measure again after a while to check and make sure you are in the serving size ball park. 


Nearly everyone with kidney disease will need to limit sodium in their diet. Too much sodium increases your blood pressure and causes fluid to accumulate in the body which results in swelling. Sodium is required to be listed on the food label.

A low sodium food item will have 140 mg of sodium in one serving. Many quick cooking/instant flavored cereals will be higher in sodium than cereals that do not have any flavors added. This is particularly important with hot cereals. 


Most Americans do not consume enough fiber.(1) Fiber helps feed the good bacteria in the gut, helps with gut transit time, and keep you feeling full and satisfied after eating a meal.

For men the recommendation is 38 grams per day and for women the recommendation is 25 grams per day. If you are looking for the best cereal for kidney disease, you want to choose one that has at least 2 grams or more of fiber per serving. 


Many cereals are loaded with sugar. It’s important to make note of how much sugar is added to a food item.

Although sugar makes foods taste good, added sugar doesn’t provide nutrients only extra unwanted calories. If you have diabetes, it’s important to limit sugar as best you can to avoid spikes in your blood sugar.

When looking at the label you will see the total sugars and below that, the added sugar. You want to make sure the added sugar is as low as possible, less than 12 grams per serving. 


Depending on if you have chronic kidney disease or end-stage renal disease, your protein needs will vary greatly. Whole grains provide a good option for plant protein and this is particularly beneficial for people with chronic kidney disease.

Some cereal will add protein to make it a high protein cereal which is beneficial to people on dialysis as their protein needs are significantly higher.

Ask your dietitian about your individual protein needs as it varies from person to person. For the purpose to this blog post we will keep protein at 5 grams or less per serving.


Like protein, potassium needs will vary from person to person depending on the stage of kidney disease and lab values. Rule of thumb is to keep potassium under 300mg per serving.

Potassium is not required to be listed on the food label. Sometimes it will be listed in the nutrition facts label as grams or a percent.

If you need to limit potassium in your diet look at the ingredient section of the food label and make sure potassium is not an added ingredient. 


This is another ingredient to pay attention to if you have kidney disease.

Phosphorus is found naturally in may foods especially whole grains. If phosphorus is found naturally in foods our bodies will absorb about 40-60% of that type of phosphorus because we do not have the enzyme phytate to help with the absorption. However, if phosphorus is added to a food item, out bodies absorb 100%.(2)

Like potassium, phosphorus is not required to be listed on the food label. The best cereals for kidney disease do not have added phosphorus, so look at the ingredient section to make sure there are no ingredients that contain “phos”.

What types of cereal are the best for kidney disease?

The cereal options for you will depend on your lab work, your kidney health goals, and your food preferences. Checking the food label is always recommended because various brands can differ.

Add-in Ideas

Cereal is good by itself but to boost the nutritional content of your breakfast you want to add-in some other food groups to round out and balance your breakfast. 



Fruit will add more vitamins, minerals, antioxidants, and phytochemials to your breakfast cereal. Some fruits have a lot more potassium than others. If you are on a low potassium diet, choose low potassium fruits to add to your cereal. *indicates a high potassium fruit.
