ROSON, M. Isabel  y  GRUPO DE ESTUDIO DE DIABETES DE LA AADYND et al. Does the consumption of meals rich in proteins and fats influence on the postprandial glucemia of patients with diabetes type 1 that follow carbohydrate counting?. Diaeta [online]. 2019, vol.37, n.167, pp.18-29. ISSN 1852-7337.

Introduction: the treatment of type 1 diabetes (DM1) requires the administration of exogenous insulin, being the carbohydrate (HC) content of the meal to be ingested one of the variables to be considered to calculate the insulin dose. For several years, this macronutrient has been considered responsible for the increase in postprandial glycemia (PPG). Carbohydrate Counting (CHC) is the most accepted and currently used method in the nutritional treatment, although there is enough evidence that other macronutrients, such as protein and fat, can influence on the variation of PPG. Objective: to gather the results of scientific publications which analysed the glycemic response (GR) to the consumption of high-protein and high-fat meals and to analyse de different interventions. After applying the inclusion and exclusion criteria, 24 articles were selected including those with individuals with DM1 from the past 10 years (with the exception of one) referring to the consumption of high-protein and high-fat meals. Results: there is a significant interpersonal variation in insulin requirements in response to dietary fat and protein, which can fluctuate by 65% +/- 10%. Randomized studies showed that in the high-fat meals, the peak of PPG was delayed and insulin sensitivity was lower. One of the studies showed that 100% of high-fat meals were associated with late hyperglycemia. Both systematic reviews emphasize the need to search for data to improve the intensive treatment of DM1, with the control of PPG being the main indicator, considering protein and fat intake, in addition to CHC. Conclusion: the effect on blood glucose of high-protein and high-fat meals usually occurs between 3 to 6 hours after being consumed, always considering the individual response and the insulin administration method. The task of the interdisciplinary team is essential to know the individual response in the DM1 patient to the consumption of high-protein and high-fat meals, thus being able to guide the decision-making process.
