Blueberry

  • Pesticide residue

    medium

    Blueberries are frequently on the EWG's Dirty Dozen list; buying organic significantly reduces exposure.

Cranberry

  • Added sugars in processed forms

    high

    Most dried cranberries and cranberry juice cocktails contain massive amounts of added sugar to balance the natural tartness.

  • Kidney stone risk

    low

    Cranberries contain oxalates, which could contribute to kidney stones in highly susceptible individuals if consumed in large amounts.

Who wins for whom

Your move

Decision guide

Choose Blueberry

Consumer tips

  1. 1

  4. 4

    Wash fresh blueberries thoroughly to remove pesticide residues, or buy organic.

    Add a handful of fresh cranberries to your smoothie for a tart kick without the added sugar of dried versions.
