Juicing is no healthier than eating whole fruits and vegetables.
Juicing extracts the juice from fresh fruits or vegetables. The liquid contains most of the vitamins, minerals and plant chemicals (phytonutrients) found in the fruit. However, whole fruits and vegetables also have healthy fiber, which is lost during most juicing.
Some believe that juicing is better than eating whole fruits and vegetables because your body can absorb the nutrients better and it gives your digestive system a rest from digesting fiber. They say juicing can reduce your risk of cancer, boost your immune system, remove toxins from your body, aid digestion and help you lose weight.
However, there's no scientific evidence that extracted juices are healthier than the juice you get by eating the fruit or vegetable itself.
But if you don't enjoy eating fruits and vegetables, juicing may be a way to add them to your diet or to try fruits and vegetables you might not eat.
Consider blending instead of juicing. Blending the edible parts of fruits and vegetables produces a drink that contains more healthy phytonutrients and fiber. Fiber can help you feel full.
If you try juicing, make only as much juice as you can drink at once; harmful bacteria can grow quickly in freshly squeezed juice. If you buy commercially produced fresh juice, select a pasteurized product.
