Based on a small randomized crossover trial conducted in Australia, protein should be considered when teaching meal insulin dosing. The study which aimed to quantify the insulin requirement for a high protein meal, concluded that on average, a high protein meal requires 54% more intravenous insulin than a low protein meal in a 5 hour postprandial period. Practice pearls reinforce the evidence that protein intake must be considered when calculating insulin dosing. But using what guidelines? Most of the insulin must be given within the first 2 hours to prevent the BS rise after protein consumption that begins 90-120 minutes after the meal. CDE's must teach our patients, especially those on high protein diets, the impact of protein on blood sugars and reinforce pre and post-prandial testing.
