What's in fruit juice?

Aside from vitamin C and calcium, fruit juice contains:

• Calories - 250ml glass of unsweetened orange juice typically contains around 100 calories, compared to the 60 calories in an actual orange
• Fructose (a form of sugar) - half a pint of fruit juice contains more sugar than the World Health Organisation recommends ideally having in a day (30g of sugar for men, 24g for women)
• A lack of fibre - juice always contains less fibre than whole fruit and highly processed juices may not contain any fiber
