Consumer tips
- 1
If buying Cranberry juice, look for 100% pure unsweetened juice and mix it with sparkling water to make the tartness palatable.
- 2
Frozen Bilberries are often more nutritious and affordable than fresh, since they are picked at peak ripeness.
- 3
Avoid dried Cranberries in trail mix—they are essentially candy coated in fruit skin.
- 4
If taking blood thinners like Warfarin, consult your doctor before loading up on either berry, as they can affect clotting.
