Juicing is not any healthier than eating whole fruits and vegetables.
Juicing extracts the juice from fresh fruits or vegetables. The resulting liquid contains most of the vitamins, minerals and plant chemicals (phytonutrients) found in the whole fruit. However, whole 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. They say that juicing can reduce your risk of cancer, boost your immune system, help remove toxins from your body, aid digestion and help you lose weight.
However, there's no sound scientific evidence that extracted juices are healthier than the juice you get by eating the fruit or vegetable itself.
On the other hand, if you don't enjoy eating fresh fruits and vegetables, juicing may be a fun way to add them to your diet or to try fruits and vegetables you normally wouldn't eat. You can find many juicing recipes online or mix up your own combinations of fruits and vegetables to suit your taste.
You might also consider blending instead of juicing. Blending the edible parts of fruits produces a drink that contains more healthy phytonutrients and fiber. And fiber can help you feel full.
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. If you buy commercially produced fresh juice, select a pasteurized product.
Also keep in mind that juices may contain more sugar than you realize, and if you aren't careful, these extra calories can lead to weight gain.
