Relationship of consumption of high glycemic index food in the diet and levels of HbA1c in type 2 diabetic patients treated with diet and / or Metformin. At present there is still no clear consensus on recommendations on the use of GI of foods for the dietary management of T2DM. Rather different entities propose the use of carbohydrate counting, because there is not even enough evidence for dietary planning based on this index. The aim of this study was to relate consumption of high GI food with glycemic control of type 2 diabetes patients from the cardiovascular health program of 3 CESFAM (Family Health Centers) in Santiago, Chile. Forty individuals were selected, anthropometric measurements were conducted as well as a modified poll of frequency of food consumption of 30 days. Data from GI, GL, number of servings with high GI consumed per day and total amount of CARB consumed per day. Correlations were determined with values of HbA1c of the last 3 month obtained from the medical record. The average age was 58.6 ± 9.5 years. The percentage of obesity was 62,5% and the average BMI was 32,5. The average HbA1c value was 7.08 ± 1.6, for HbA1c <7% it was 57,5%. The total amount of CARB ingested/day was 403,8 g. The average of GI and GL was 78.5 and 317.5 respectively. The total number of servings of food with high GI ingested per day was 21,8. There was a statistically significant correlation between HbA1c and number of servings with high GI (r= 0.56 p=0.002). For the remaining variables there was no statistically significant correlation (p>0.05). For each extra serving of high GI food there was an increase of 0.9% of HbA1c. In our research population the amount of food with high GI ingested per day was significantly correlated with values of HbA1c.
