Do you remember when the price of fizzy drinks in the UK went up slightly a few years ago? Well, this was because the UK government introduced a sugar tax (or the Soft Drinks Industrial Levy, to be precise), requiring manufacturers to pay a tax on sugary drinks - a cost which was then passed on to the customer. Following the success of this tax (perhaps not for your pocket, but fizzy drinks now contain less sugar) we're asking public health nutritionist Dr Lauren Bandy - is a snack tax on the horizon?
