It is easy to make blueberry crumble when you keep blueberries on hand, so if you have some kicking around your freezer, you probably already have all the ingredients you need without having to take a trip to the store!

These sweet berries are a kidney superfood because they contain anthocyanins, antioxidants that may protect against cardiovascular disease, certain types of cancer, cognitive decline, and diabetes. Additionally, they are low in sodium, phosphorus, and potassium, so they are a great addition to a kidney-friendly diet, which is why we’re here. Just remember, it’s ok to keep blueberries frozen but do not buy frozen blueberries and keep them. Frozen fruit tends to be high in sodium.

The benefits of blueberries for kidney disease include: 

  1. Low in potassium
  2. High in antioxidants
  3. Anti-inflammatory food

Blueberries are one of the low potassium fruit choices, as they contain less than 150 milligrams of potassium per serving. A kidney-friendly diet can benefit from blueberries' low sodium and phosphorus content.

They are safe to eat for most kidney conditions or treatments, including:

  • Chronic kidney disease/transplantation
  • Hemodialysis (three times a week)
  • Daily peritoneal dialysis and nocturnal hemodialysis
  • Kidney stones

And now, what you’re really here for - the recipe for this superfood dessert:

Kidney Healthy Blueberry Cobbler


  • 4 cups blueberries
  • 1 tsp lemon juice
  • 1 cup all-purpose flour
  • 1/3 cup sugar
  • 1 tsp baking powder
  • 1/2 tsp ground cinnamon
  • 1/4 tsp ground nutmeg
  • 1 tbsp sunflower oil
  • 1/2 tsp vanilla extract
  • 2 eggs


In a large bowl, put blueberries with lemon juice until evenly coated. Coat an 8×8 baking pan with sunflower oil. Pour berries into the baking dish.

In a medium bowl, combine flour, sugar, baking powder, cinnamon, and nutmeg. Mix to combine.

In a small bowl, whisk together oil, vanilla, and eggs. Pour egg mixture into the flour mixture and mix, just until combined.

Dollop dough over berries, covering as evenly as possible. Bake at 350'F until dough is golden brown and cooked through, 40-50 minutes. 

A warmed blueberry cobbler is the best way to serve this healthy dessert. Try it with a little ice cream! The cobbler can be kept in the refrigerator for 2-3 days. If you don't eat it right away.
