“…Since 2003, a new procedure of using D‐W/S‐W boluses has been implemented in the Department of Paediatrics of the Medical University of Warsaw. This procedure was built based on the three main assumptions: meals containing fat and/or proteins should be covered by insulin (e.g., carbohydrate products), meal absorption depends on the type of nutrition product (e.g., rich on fat meals are absorbed during an extended period of time) and insulin dose should be programmed separately for carbohydrate products in N bolus and for fat or/and protein ingredients in the S‐W bolus (11, 12). A new, fat–protein exchange factor was added to the food counting system – defined as 100 kcal of fat and/or protein foods.…”
