Fiber in Diet Is Associated with Improvement of Glycated Hemoglobin and Lipid Profile in Mexican Patients with Type 2 Diabetes

Abstract

Objective. To assess the association of dietary fiber on current everyday diet and other dietary components with glycated hemoglobin levels (HbA1c), glucose, lipids profile, and body weight body weight, in patients with type 2 diabetes. Methods. A cross-sectional survey of 395 patients with type 2 diabetes was performed. HbA1c, fasting glucose, triglycerides, and lipids profile were measured. Weight, waist circumference, blood pressure, and body composition were measured. Everyday diet with a semiquantitative food frequency questionnaire was evaluated. ANOVA, Kruskal-Wallis, chi-square tests and multivariate logistic regression were used in statistical analysis. Results. Higher fiber intake was associated with a low HbA1c, high HDL-c levels, low weight, and waist circumference. The highest tertile of calories consumption was associated with a higher fasting glucose level and weight. The highest tertile of carbohydrate consumption was associated with a lower weight. The lowest tertile of total fat and saturated fat was associated with the highest tertile of HDL-c levels, and lower saturated fat intake was associated with lower weight (p < 0.05). Conclusions. A higher content of fiber in the diet reduces HbA1c and triglycerides, while improving HDL-c levels. Increasing fiber consumption while lowering calorie consumption seems to be an appropriate strategy to reduce body weight and promote blood glucose control.

Sexually Dimorphic Response of Increasing Dietary Intake of High Amylose Wheat on Metabolic and Reproductive Outcomes in Male and Female Mice

“…Dietary fibre plays an important role in maintaining good health and is associated with improvement of glycaemic response and plasma lipid profile [29,30]. However, consistent with previous findings [22], the HAW diets had no effects on fasting blood glucose concentrations or plasma lipid profiles despite the higher dietary fibre content in the HAW diets compared to the SAW diet.…”

Dietary patterns of patients with chronic coronary heart disease: a cross-sectional study

“…Both dietary patterns had insufficient fiber intake, despite the significant difference found. Fiber consumption is important for adequate glycemic control in diabetic individuals 24,25 . In the current study, patients following dietary pattern I presented significantly lower levels of HbA1 than the ones from pattern II, even though for both groups the glycated hemoglobin value was outside the target (<7%).…”

Health behaviour change considerations for weight loss and type 2 diabetes: nutrition, physical activity and sedentary behaviour

“…45 Dietary fibre can delay the digestion and absorption of glucose and increase satiety, which can help with weight loss. Intake of dietary fibre is associated with improved glycaemia and a lower prevalence of hypertension, obesity and metabolic syndrome in individuals living with T2DM 46,47 and should thus be considered when making changes to dietary behaviour.…”
