Oatmeal can often be overlooked as a great kidney-friendly and gut-friendly meal option. Many think of oatmeal as a bland and boring breakfast option. This is so far from the truth! Oatmeal can be turned into a delicious lunch or dinner meal by adding more flavor and a few extra ingredients. It can also be a powerhouse of fiber and prebiotics! 

Oat Origins 

Resources show that oats were first consumed about 30,000 years ago. Oats were first eaten as a porridge-type meal, similar to how oatmeal is eaten today. It was not until the 1900s that oatmeal became a popular breakfast food in the U.S. Nowadays, oatmeal is eaten for breakfast and is often a more sweet meal. 

Nutrition Information

What makes oats so popular? Oatmeal can also be a quick and easy meal when you’re busy and on the go. Not only are oats easy to cook, but oats also contain powerful health benefits. Oats are a great source of fiber, prebiotics, and beta-glucan, which have been shown to help lower cholesterol, modulate the gut microbiome, and protect against heart disease (3,4). For a full look at the nutrition information for oats, see below. Oats are a naturally low-fat, low-protein, low-potassium, and low-sodium food. Because of these health benefits and the nutrition profile of oats, they are a kidney and gut-friendly food option for those with CKD.

Now, if making a bowl of plain oatmeal each morning doesn’t appeal to you, try savory oatmeal instead! Savory oatmeal can be a quick, lower protein, and fiber-rich option if you have CKD. My savory tomato oatmeal contains a few extra ingredients to add fiber and prebiotic benefits. It’s also a great alternative to risotto or pasta. Check out my favorite recipe for savory tomato oatmeal below, and let me know what you think. 

Savory Tomato Oatmeal


  • 1/2 cup dry oats
  • 1-2 cups water

  1. Cook oatmeal according to the package. 
  2. While the oatmeal is cooking, in another pan, sauté garlic in olive oil for 2 minutes or until slightly fragrant. 
  3. Next, add cherry tomatoes and cook until the tomatoes have burst. Add arugula until wilted.
  4. Once the oatmeal is cooked, turn off the heat and add tomatoes, garlic, and arugula to oatmeal. Mix well.
