Blueberries
Blueberries are often described as a superfood. High in vitamin C and antioxidants, they can help keep our bones, skin, heart and even our minds healthy. They contain the antioxidant compound anthocyanin, which makes blueberries blue. Surprisingly you can increase this little fruit’s nutritional benefits by freezing it. Studies show that ice crystals on the frozen fruit’s skin makes anthocyanin even more concentrated. Blueberries grow well in a big barrel or tub in slightly acidic soil. Don’t forget to feed them!
