When you visit a coffee shop this festive season, you may be tempted by an indulgent Christmas coffee. But before you place your order at Costa, McDonald's, Starbucks or other popular high street chains, it pays to know you could be downing as much sugar as a chocolate bar.
We took a look at six takeaway caramel, toffee or nut-based lattes promoted as seasonal specials and discovered that the worst offender contained as much sugar as a full-sized Cadbury Crunchie bar.
This was despite the fact that the beverages scrutinised were all made with semi-skimmed milk and were in 12fl oz/330ml cups - the smallest size you can order in the majority of places.
When supersized, some of the worst offenders contained as much as 47.4g sugar - almost the equivalent of two full-sized Boost bars.
All nutritional data was taken from the coffee company's websites if you want to check before you buy.

Caffu00e8 Nero's festive caramel latte is a blend of coffee with salted caramel syrup, and is customisable with whipped cream, caramel sauce and marshmallows.

By adding these in, you'll be adding more sugar to those listed below.
