The one thing you get a lot of in fruit juices is sugar. There is nearly as much sugar in a glass of orange juice (8 grams/100 mls or 8 per cent) and apple juice (10 per cent) as there is in Coca-Cola (10.6 per cent). However, surely the fact that the sugar in juice is ‘natural’, coming as it has from fruit, means it is better for you then the refined stuff added to soda? Absolutely not true. The vast majority of sugar in juice and in soda is sucrose, which is a disaccharide formed of one molecule of glucose and one molecule of fructose.
