Are you partial to blueberry muffins? If you are, did you ever stop and think that just one could contain more than your entire recommended daily sugar allowance? According to an analysis in January by Action on Sugar and the Obesity Health Alliance, a single blueberry muffin can contain as much as eight teaspoons of sugar. The recommended daily intake for adults in the UK is just seven and it’s even less for children. The analysis highlights just how easy it is for people to exceed the recommended daily intake without even knowing it. For the analysis, Action on Sugar and the Obesity Health Alliance looked at 28 different muffins sold in a variety of locations, such as train stations and supermarkets. It found that 61% contained at least six teaspoons of sugar. Furthermore, muffins purchased at train station retailers had 19% more sugar per portion and were 32% bigger than those found in supermarkets. Caroline Cerny, from the Obesity Health Alliance, said: "We may think grabbing a blueberry muffin is a reasonably healthy option for a snack on the go compared to other cakes or a chocolate bar - yet the figures suggest otherwise. "There is huge variation in both the size of muffins and the sugar content, and with limited nutrition labelling, it's all too easy to eat a huge amount of sugar in just one serving."
