Low-Glycemic Diet Shows Greater Improvement in Glycemic Control Than High-Fiber Diet
People with type 2 diabetes, the diet rich in low glycemic foods such as nuts, beans and lentils are a greater improvement of glycemic control and risk factors for coronary heart disease, that people with a high fiber diet to focus on cereals, such as a study of the issue of 17 JAMA December.
Foods for improving the control of diabetes and cardiovascular risk factors, the use of low glycemic index, but there is disagreement about the effectiveness according to the basic information in the article.
David JA Jenkins, MD, St. Michael's Hospital and the University of Toronto and his colleagues investigated the effects of a low glycemic index compared to a system with a high proportion of dietary fiber in cereals in the diet for the control of blood glucose and risk factors for cardiovascular -210 patients with type 2 diabetes. The participants who received healing antihyperglycemic randomized 1 of 2 treatments of food and 6 months.
In the diet with low glycemic index, the following elements in foods: beans, peas, lentils, nuts, noodles, rice, cooked quickly and with a low glycemic index breads (including pumpernickel, rye bread, quinoa, flaxseed and y) and cereal for breakfast (including the largest and oats oatmeal). In the upper level for fiber cereals, participants were invited to the "brown" choice (bread, cereal, whole beans, rice, potatoes with skin, bread, biscuits and breakfast cereals). Three servings of fruit and five servings of vegetables was the two treatments.
The researchers found that Hemoglobin A1c (HbA1c, a substance in red blood cells in the test to the level of glucose in the blood) to -0.50 percent HbA1c absolute units in the diet with low glycemic index compared to a absolute terms - 0.18 percent in the HbA1c value of foods with high fiber cereal. Effects of treatment were in high-density lipoprotein (HDL-C) and low density lipoprotein cholesterol (LDL-C): HDL-C. HDL-C in the diet with low glycemic index of the group of 1.7 mg / dL and 0.2 mg / dl in the high cereal fiber diet group. LDL-C: HDL-C showed a greater reduction in the proportion of low glycemic index compared to the group of foods rich in dietary fiber from cereals group.
"The reduction of the glycemic index system improves the control of blood glucose and risk factors for coronary heart disease (CHD). These data have important implications for the treatment of diabetes, if the target has been adjusted, the control of blood glucose to avoid complications. The reduction The HbA1c value is low, but it Clinic, "the authors write." low glycemic index diet in May, as part of a strategy to improve glycemic control in diabetes type 2 patients taking antihyperglycemic drugs. "
"Pharmacological interventions to improve glycemic control in type-2-diabetes often do not show a significant reduction of cardiovascular events. In view of the 2 - to 4-times higher risk for coronary heart disease in participants with type 2 diabetes, the ability to Foods with low glycemic index, for control of blood glucose and risk factors for coronary heart disease increases the clinical relevance of this approach for patients with type 2 diabetes, as in this study, the overweight are among the statins and the risk of diseases of the heart.
