Frozen blueberries may be even healthier than fresh ones. This is because they retain more substances that help the body protect itself from disease.
When blueberries are frozen, they retain more antioxidants, which are lost over time in fresh fruit that sits on the shelf for too long. These substances help the heart and brain function better.
Studies show that freezing increases a compound called anthocyanin, which gives blueberries their blue color and makes them very beneficial for health.
So, if you can't always find fresh blueberries, frozen ones are an equally good, even healthier, choice.
