Juicing probably is not any healthier than eating whole fruits and vegetables because fruits and vegetables also have healthy fiber, which is lost during most juicing.
Some juicing proponents say that juicing is better for you than is eating whole fruits and vegetables because your body can absorb the nutrients better and it gives your digestive system a rest from working on fiber.
However, there's no sound scientific evidence that extracted juices are healthier than the juice you get by eating the fruit or vegetable itself.
If you do try juicing, make only as much juice as you can drink at one time because fresh squeezed juice can quickly develop harmful bacteria.
