A European study has revealed that 100 percent fruit and vegetable juices are as effective as their whole fruit/vegetable counterparts in reducing risk factors related to certain diseases. The conclusion is the result of the study designed to question traditional thinking that 100 percent juices play a less significant role in reducing risk for both cancer and cardiovascular disease than whole fruits and vegetables.
Juices are comparable in their ability to reduce risk compared to2 their whole fruit/vegetable counterparts， according to several researchers in the United Kingdom who conducted the literature review. The researchers analyzed a variety of studies that looked at risk reduction attributed to3 the effects of both fiber and antioxidants. As a result， they determined that the positive impact fruits and vegetables offer come not from just the fiber but also from antioxidants which are present in both juice and the whole fruits and vegetables.4
“When considering cancer and coronary heart disease5 prevention， there is no evidence that pure fruit and vegetable juices are less beneficial than whole fruit and vegetables，” the researchers said. The researchers added that the positioning of juices as being nutritionally inferior to6 whole fruits and vegetables in relationship to chronic disease development is “unjustified” and that policies， which suggest otherwise about fruit and vegetable juices， should be re-examined.

In fact， that study found that individuals who drank three or more servings of fruit and vegetable juices per week had a 76 percent lower risk of developing Alzheimer’s disease than those who drank juice less than once per week. The study was published in the International Journal of Food Science and Nutrition11 (2006).
