Do you know what is going into that smoothie you are drinking? Such drinks have become big business today, and words like “healthy” and “natural” have been used in order to describe them. Yet the smoothies you purchase in your local supermarket may not be all that they seem. These products often have labels either depicting a blender full of fruit or a sunny outdoor scene to convey the image that they contain vital living ingredients. But in many cases these smoothies have been prepared on a very large scale using large industrial machines as well as vats of fruit purees that to help extend their life have been pasteurized.
