If fruit juice is made from fruit, surely it contains the same goodness as whole fruit, right? Juicing extracts the sweet, sweet juice from fresh produce so fruit juices do contain most of the vitamins, minerals and good phytochemicals found in whole fruits. But however your juice comes — cold-pressed, freshly squeezed, "nothing but" juice — juicing fruit strips out the fibre. And it's the fibre which is good for gut health and has a host of other health benefits, too. Fibre also makes you feel full, which means drinking sans-fibre fruit juices, no matter how thirst-quenching, is just less satisfying than eating fruit. "This means that it is quite easy to consume a large amount of juice [and sugars] in one go without feeling very full, so they are often a significant source of energy," says Dr Carly Moores, a registered nutritionist at the University of Adelaide. Even if fruit juices contain some pulp, they are still lower in fibre and less beneficial than eating whole fruits, she adds.
