Hugh is surprised to learn bottles of fruit juice and smoothies can contain as much sugar as a can of fizzy pop. He is also confused that the labels on the bottles seem to suggest that anything up to 330ml is a single portion size, when, in fact, the government recommends not drinking any more than 150ml of juice or smoothie a day.
