PINCHEIRA, Daniela; MORGADO, Romina; ALVINA, Marcela  and  VEGA, Claudia. Quality of carbohydrates in the diet and their effect on metabolic control of type 2 diabetes. ALAN [online]. 2014, vol.64, n.4, pp.241-247. ISSN 0004-0622.

The Objective of this study was to determine the relationship between the parameters of metabolic control and quality of carbohydrates (CHO) of the diet in individuals with type 2 diabetes, controlled with diet and / or Metformin. In 108 men and women aged between 18 and 60 years, glycosylated hemoglobin A (HbA1c) between 6 % and 10 %, without sulfonylureas or insulintheraphy; were examined through two separate surveys of 24-hour recall. The CHO intake, GI, GL of diet was analyzed. Values of HbA1c were collected from medical records. Data was tabulated in SPSS version 17 software. The Pearson correlation test was used to analyze the degree of association between variables, considering significant at p < 0.05. The mean HbA1c was 7.3 ± 1.3%, CHO consumption was 219.8 ± 27.0 g / day; GI was 74.9 ± 11.3% and GL was 164.0 ± 22.04 g. A significant positive correlation was found out between the CHO intake (r = 0.290, P < 0.05), GI (r = 0.70, p < 0.001), GL (r = 0.225, p < 0.05) of diet and HbA1c levels in the individuals. In conclusion the study showed that the quality of CHO, mainly GI, are strongly associated with metabolic control of DM 2.
