Preferably, the best form of fruits would be the fruits themselves - before any form of juicing or processing at all! If you really want to give fruit juice, give those freshly made ones by reputable and credible fruit stalls (the ones that you know are certified clean and have good hygiene practices) - or make them at home yourself :) I'd stay away from any kind of packaged/processed fruit juice (eg. those in supermarkets, or sold in tetrapak packets etc) because they're usually loaded with sugar and additives!
