Beneficial Effects of High Dietary Fiber Intake in Patients with Type 2 Diabetes Mellitus

Abstract

A high intake of dietary fiber, particularly of the soluble type, above the level recommended by the ADA, improves glycemic control, decreases hyperinsulinemia, and lowers plasma lipid concentrations in patients with type 2 diabetes.

Impact of sugar beet pectin and polydextrose on fasting and postprandial glycemia and fasting concentrations of serum total and lipoprotein lipids in middle-aged subjects with abnormal glucose metabolism

“…In previous studies, guar gum (Aro et al, 1981;Fuessl et al, 1987;Groop et al, 1993) as well as other sources of soluble fiber (Vuksan et al, 1999;Chandalia et al, 2000;Pins et al, 2002) have been reported to result in either a significant or a nonsignificant decrease in blood or plasma glucose concentrations. There were no significant differences in GHbA1c between the groups.…”

“…Previous studies have shown a small decrease by soluble fiber in serum total and LDL-cholesterol concentrations without a decreasing effect on HDL-cholesterol (Brown et al, 1999;Knopp et al, 1999;Anderson et al, 2000;Vuksan et al, 2000). Regarding concentrations of serum triglycerides, the results are controversial; in some studies dietary fiber has been shown to have no effect on the concentration of serum triglycerides (Vuksan et al, 1999(Vuksan et al, , 2000, whereas in some other studies a decreasing effect of dietary fiber has been reported (Chandalia et al, 2000). The most commonly reported negative effect of fructose on serum lipid profile has been the increased concentration of serum triglycerides ( Bantle et al, 2000).…”

“…The study by Chandalia et al (2000) showed a beneficial effect of dietary fiber on glucose homeostasis in subjects with DM2. Intake of soluble fiber has been shown to improve postprandial glucose metabolism, and guar gum, a soluble fiber, has been shown to improve glucose concentrations in DM2 patients (Aro et al, 1981;Fuessl et al, 1987;Groop et al, 1993).…”

Arabinoxylan consumption decreases postprandial serum glucose, serum insulin and plasma total ghrelin response in subjects with impaired glucose tolerance

“…Well-balanced diets rich in dietary fibre have beneficial effects on risk markers of the metabolic syndrome (Chandalia et al, 2000;Jang et al, 2001;McKeown et al, 2002;Pereira et al, 2002;Liese et al, 2003). Dietary fibre can be classified according to its viscosity (Fernandez, 2001).…”

Long-term effect of dietary fibre intake on glycosylated haemoglobin A1c level and glycaemic control status among Chinese patients with type 2 diabetes mellitus

“…As a biomarker reflecting an individual's average level of blood glucose over past 2-3 months, glycosylated haemoglobin A1c (HbA1c) has been associated with the risk of long-term diabetes complications (5) and used as the main indicator of glycaemic control status among diabetes patients (6) . The American Diabetes Association recommends an HbA1c level below 7?0 % as the goal of glycaemic control for diabetes patients (6) .There is sufficient evidence to support the role of dietary fibre in improving glycaemic control status in diabetes patients (7)(8)(9) . Evidence is also available for its beneficial effect on prevention of diabetes complications.…”
