While it is widely accepted that fruit and vegetables (F&V) lower
the risk of cancer, and cardiovascular disease (CVD), the role of pure
fruit and vegetable (PFV) juices is often downplayed. This review poses
two questions: Are the protective benefits of F&V dependent upon
constituents lacking in PFV juices (e.g. fibre)? Do PFV juices impact on
disease risk when considered separately from F&V? Studies comparing the
effects of fibre and antioxidants were reviewed, yielding the finding
that the impact of F&V may relate more strongly to antioxidants, than to
fibre. For the second question, high-quality published studies that
considered PFV juices were reviewed. The impact of PFV juices on cancer
risk was weakly positive, although a lack of human data and
contradictory findings hampered conclusions. For CVD, there was
convincing evidence from epidemiological and clinical studies that PFV
juices reduced risk via a number of probable mechanisms. It was
concluded that the view that PFV juices are nutritionally inferior to
F&V, in relation to chronic disease risk reduction, is unjustified.
