Is it me or is there something very strange with the Carb content of some food? I enjoy snacking on a bag of Macadamia Nuts every now and then but am confused by the variance in Carbs from different stores. If I buy a 100g bag in Sainsburys, the carb content is listed clearly as 4.7g per bag. However, an almost identically looking bag in Tesco (also 100g) states that the carb content is only 2.6g per bag. Can anyone explain why they differ so much when they are both supposed to be just an ordinary bag of Nuts and taste exactly the same?

Happy Cooking!
