When we eat carbohydrates they break down to more simple sugars which increase our blood sugar. Our body prefers this energy source to others but in diabetes the process of using this energy doesn’t work as well. That makes it really important to choose carbohydrates that make it easier on the body to use the fuel you give it. Choosing low glycaemic index foods is one great way to do this. For more details and ideas on carbohydrate swaps take a look at this British Dietetic Association factsheet.
