Hyperoxaluria and Genitourinary Disorders in Children Ingesting Almond Milk Products

J Pediatr. 2015 Nov;167(5):1155-8. doi: 10.1016/j.jpeds.2015.08.029. Epub 2015 Sep 15.


We describe 3 children presenting with hematuria, dysuria or kidney stones, and hyperoxaluria believed to be related to ingestion of excessive amounts of almond milk products. Our investigation of the oxalate content of several popular plant-based milk substitutes indicates that almond milk products are a particularly rich source of dietary oxalate. All genitourinary and urinary metabolic disturbances resolved after discontinuation of almond milk ingestion. Therefore, pediatricians should be aware of this potential link.
