Abstract: Background: Gum Arabic (acacia Senegal) is a safe dietary fiber indigestible to both humans and animals. Lipid lowering effect of Gum Arabic (GA) was extensively studied in animals; on the other hand a paucity of data regarding the effects of GA on metabolic elements in patients with Type 2 Diabetes Mellitus (T2DM), this study was conducted to determine the effects of regular (GA) ingestion on control of metabolic elements among T2DM. Methods: A two-arm randomised, placebo controlled, double-blind trial was conducted at Academy Charity Teaching Hospital, Khartoum. Total number 91 patients with T2DM completed the study. They were divided to two groups: A test group of 46 patients were received oral GA (30 gm /day) for 3 months and a group of 45 patients were received oral pectin (5 gm/day) as a placebo for the same period of time considering taking their anti-diabetic drugs. Weight, height, waist circumference, blood pressure, triglyceride, cholesterol, LDL, FBG and HDL, were measured before and after intervention. Results: Pre and post intervention results were compared to the control group (mean ± SD) showed significant decrease of FBG (145.61±38.82 mg/dl vs. 197.43±62.09 mg/dl pre- intervention, p<0.05), decrease of systolic and diastolic blood pressure by 7.6% and 6.8% respectively within GA group. Lipid profile was decreased by 5.9% for LDL-Cholesterol and 8.3% for Total Cholesterol. Triglycerides significantly decreased (121.22±52.10 mg/dl vs. 136.15±55.74 mg/dl pre-intervention, p<0.05). HDL-Cholesterol showed boarder line increase by 19.9% within GA group with insignificant increase compared to placebo group. Waist circumference significantly decreased by 1.4% within GA group and decrease of BMI (27.09±5.49 vs. 27.66±5.37 pre-intervention, p<0.05) Also another visceral fat distribution indicator is the visceral adiposity index (VAI) has shown significant decrease (2.43±1.82 vs. 3.17±2.29 pre-intervention, p<0.05). Conclusions: GA decrease risk of diabetes mellitus complications by strict control of metabolic elements in patients with type 2 diabetes mellitus. Key words: Gum Arabic, T2DM, BMI, LDL, HDL, Cholesterol, Triglycerides.
