There has been a long ongoing controversy about whether fruit juices are healthy or not. Most people consider them to be a great option to complete their daily fruit requirement since they are much easier to consume.
Lots of people replace soda and carbonated drinks with fruit juices thinking that they are moving towards an healthier option. There are even detox diets which claim to help you lose weight by just drinking fruit juices. They might help you in the short run but the fact is there is not much difference between a tall glass of fruit juice and a bottle of any carbonated drink minus the fizz.
