Type 1 diabetesCounting carbohydrates

Carbohydrates (carbs) are in foods like:

  • potatoes, rice, bread and pasta (starches)
  • milk, fruit and honey (sugars)

Knowing how many carbs you're eating and drinking helps you manage your blood glucose levels by matching your insulin dose to the amount of carbs in your meals and snacks.

This means you don't have to inject and eat at the same time every day (fixed dose), so your treatment is more flexible.

You can start learning about carb counting by:

  • asking your diabetes team if they run carb counting sessions
  • doing a dose adjustment for normal eating (DAFNE) course
  • doing a course online to learn how to count carbs

Diabetes UK has a series of videos giving a brief introduction to carb counting.
