Blueberries are super nutritious they contain dietary fibre, vitamins (A, B, C, E), minerals (selenium, zinc, iron, and manganese), and other phytonutrients (resveratrol, beta-carotene, lutein, zeaxanthin, flavonoids (anthocyanins), flavanols, and phenolic acids (hydroxycinnamic acid))
From the phytonutrient list, a flavonoid called anthocyanin may play the biggest role in promoting health. Anthocyanins provide the colour pigment found in red, purple, blue, or black coloured fruits and vegetables. The amount of anthocyanin rise as the fruit ripens to help with the colour identification of a fully ripe compared to unripe fruit.

This superfood is so easy to include in your diet. They are my favourite fruit, but I actually prefer to consume them frozen as a treat. Other women may prefer them fresh or dried. You can eat them alone or add them to your salads, smoothie, chia seed pudding, breakfast cereals or blended frozen into a yummy sorbet. Just do it regularly!
