Açai Berries

Açai (ah-sigh-EE) berries are small fruits that grow in clusters like grapes and have a center pit.  They have a very short shelf life, so are usually found as powders, frozen fruit puree, or pressed juice. Açai is often used in smoothies or in an açai berry bowl. It has an earthy taste with a cross between blackberry or raspberry and chocolate.

Why are açai berries a superfood?

  • Açai berries contain antioxidants, specifically anthocyanins and polyphenols. Antioxidants are substances that have been linked to preventing or delaying some types of cell damage. 
  • Anthocyanins have been linked to some potential health benefits, including decreased inflammation, reduced symptoms of arthritis, and protection against certain cancers.
  • Polyphenols, fiber, and heart-healthy fat in açai berries have been linked to possibly helping support heart health.

Açai berries and kidney disease

Açai berries are acceptable foods for chronic kidney disease (CKD), as well as for patients on dialysis. However, açai smoothies and bowls are usually prepared with fresh fruits and vegetables. Depending on the diet as a whole and potassium levels in the blood, one may need to be cautious about the potassium content of those foods.  Discuss these considerations with a kidney dietitian.


Raw açai juice has not been tested well enough to determine any possible interactions with transplant medications. Check with your transplant team for guidance.

Kidney Stones

There are no reports linking the severity of or recovery from kidney stones in people who eat açai.
