Blueberries and cranberries contain a category of antioxidants called anthocyanins. Beyond giving the berries their distinct colors, these antioxidants have been connected to several liver health benefits.

Eating blueberries and cranberries daily for 3-4 weeks has been shown to protect the liver by preventing the development of lesions, scar tissue, and fibrosis. Blueberries in particular increase immune cell response as well as antioxidant enzymes. Blueberry extract also inhibits the growth of liver cancer cells in test tube studies, but more research in humans is necessary.
