Everyone knows that it is useful to eat fruits and vegetables. This is because they are full of important substances such as vitamins, minerals, fiber and phytonutrients that help our bodies do what they do best. Eating (or drinking) a rainbow of fruits and vegetables will help you get a lot of these smart nutrients into your diet. You only need to drink 150ml glass of innocent juice or smoothie to get a good chunk of the nutrients you need per day.
