Correct. The answer is 6 units.

Using: ( ICR 1: 5 )

1 units of insulin : for every 5 carbs consumed with the following snack gives us:

  • 27 grams of carbs (estimated)

  • 3g total carbs (estimated)

1 banana + 1 tablespoon of peanut butter =

27 grams of carbs + 3 grams of carbs =

30 total grams of carbs

30 divided by 5 [our ICR number] is 6 so the amount to take would be: 6 units

If you skip insulin for snacks, you may be dealing with high blood sugars later on!
