Avanzini F, Marelli G, Amodeo R, et al. - Researchers conducted this prospective pre-post intervention study to evaluate the impact on the incidence of hypoglycaemia of giving prandial insulin immediately after a meal depending on the amount of carbohydrate ingested. The oral carbohydrate intake was lower than planned on at least one occasion (median: 3 times; Q1–Q3: 2–6 times) over a median of 5 days in 83 of the first 100 people treated with the ‘brick diet’. In hospitalized people with diabetes who have been treated with subcutaneous insulin, the ‘brick diet’ offers a practical method of counting the amount of carbohydrates ingested, which is often less than planned. Prandial insulin given immediately after a meal, decreases the risk of hypoglycaemia in doses balanced with actual intake of carbohydrates.
