Whether you need to snack depends on many factors, including the type of diabetes you have, your insulin-taking programme and how active you are. Young children need to snack as they can't get all the food they need from three main meals.
If you have diabetes, you'll want something that will satisfy your hunger, be low in fat and sugar, and not have a big effect on your blood sugar levels. Too many unnecessary snacks can lead to higher blood sugar levels, extra fat and unwanted calories.
If you have Type 1 diabetes and have been on a carb-counting course, such as DAFNE, you’ll know that snacks with less than 10g carbs don’t usually require extra insulin injections.
