LUNA LOPEZ, Victoria; LOPEZ MEDINA, José Antonio; VAZQUEZ GUTIERREZ, Mercedes  and  FERNANDEZ SOTO, M.ª Luisa. Carbohydrate: current role in diabetes mellitus and metabolic disease. Nutr. Hosp. [online]. 2014, vol.30, n.5, pp.1020-1031. ISSN 1699-5198.  https://dx.doi.org/10.3305/nh.2014.30.5.7475.

Background: There is a prevalence of diabetes mellitus (DM), unknown DM and stress hyperglycemia among hospital patients, and the nutritional treatment is a key part of care, where carbohydrates (CH) intake is a controversial issue. There is also a discussion on the increase of prevalence for DM, obesity and metabolic disease with refined CH or sugar. Objectives: This review examines the recommendations from different scientific societies about the percentage of CH in the total calorie intake of the diabetic patient, the CH value in the glycemic index and glycemic load, the new CH included in enteral formulae and the association of refined CH with the high prevalence of DM and metabolic disease. Methods: Systematic review of literature using the electronic scientific databases Pubmed, Science Direct, Scielo, Scopus and Medline. Conclusions: Scientific societies are flexible about the CH intake in the diet of diabetic patients, suggesting to customize it according to each metabolic profile. Using the glycemic index and glycemic load can provide an extra benefit in the postprandial glycemic control. The new diabetes-specific enteral formulae, with fructooligosaccharides, resistant maltodextrins and fructose-free show efficacy in improving the glycemic control, although more controlled and long-term studies are needed. There is still some controversy about the links between sugar intake and DM, obesity and metabolic disease, although this relationship would be more linked to an increase of the total calorie intake than to a specific nutrient.
