For decades fruit juice has been seen as a healthy option. Then this week a primary school banned it after claims that it's as bad for you as Coca-Cola. But how big a health risk does it pose?

his week, it looked as if fruit juice might finally lose its claim to healthiness and be put into the same category as fizzy drinks.
