Christmas time is full of food when most of us simply have to worry about our expanding waist lines but new research says that people with diabetes need to pay attention to the dangers of a neglected post meal peak in blood glucose. Indeed the research shows that this post meal peak can do even more damage than a more sustained rise in blood sugar. Until recently, the main focus of therapy for people with diabetes has been on lowering blood sugar or glycated haemoglobin (HbA1c) levels, with a strong emphasis on fasting plasma glucose.
