Why are blueberries considered a superfood?

Blueberries have over 80 defined nutrients, essential vitamins, fibre and antioxidants that help protect and heal your entire body. They are especially high in phytochemicals that help fight free radical damage from stress, bad diet, disease, pollution, medication and other toxins. The blue colour in blueberries is due to the phytochemical anthocyanin that not only helps prevents cellular damage but also reduces inflammation, two of most common issues that cause ill health.

Why does freezing blueberries make them better?

When fruit is frozen it changes the molecular structure and often reduces its nutritional value. However this is not the case with Blueberries, which actually improve nutritionally from being frozen. Studies show that even after 6 months of being frozen blueberries' antioxidant levels stayed the same as fresh blueberries. Even more incredible is that their anthocyanin levels increased making them even more beneficial for good health.

Are organic berries really better?
