    Effects of gum Arabic ingestion on body mass index and body fat percentage in healthy adult females: two-arm randomized, placebo controlled, double-blind trial
    (Nutrition Journal, 2012) Babiker,Rasha; Merghani,Tarig H; Elmusharaf,Khalifa; Badi,Rehab M; Lang,Florian; Saeed,Amal M
    Background: Gum Arabic (acacia Senegal) is a complex polysaccharide indigestible to both humans and animals. It has been considered as a safe dietary fiber by the United States, Food and Drug Administration (FDA) since the 1970s. Although its effects were extensively studied in animals, there is paucity of data regarding its quantified use in humans. This study was conducted to determine effects of regular Gum Arabic (GA) ingestion on body mass index and body fat percentage among healthy adult females. Methods: A two-arm randomized, placebo controlled, double-blind trial was conducted in the Department of Physiology at the Khartoum University. A total of 120 healthy females completed the study. They were divided to two groups: A test group of 60 volunteers receiving GA (30 gm /day) for 6 weeks and a placebo group of 60 volunteers receiving pectin (1 gm/day) for the same period of time. Weight and height were measured before and after intervention using standardized height and weight scales. Skin fold thickness was measured using Harpenden Skin fold caliper. Fat percentage was calculated using Jackson and Pollock 7 caliper method and Siri equation. Results: Pre and post analysis among the study group showed significant reduction in BMI by 0.32 (95% CI: 0.17 to 0.47; P<0.0001) and body fat percentage by 2.18% (95% CI: 1.54 to 2.83; P<0.0001) following regular intake of 30 gm /day Gum Arabic for six weeks. Side effects caused by GA ingestion were experienced only in the first week. They included unfavorable viscous sensation in the mouth, early morning nausea, mild diarrhea and bloating abdomen. Conclusions: GA ingestion causes significant reduction in BMI and body fat percentage among healthy adult females. The effect could be exploited in the treatment of obesity.

    Metabolic effects of Gum Arabic (Acacia Senegal) in patients with Type 2 Diabetes Mellitus (T2DM): Randomized, placebo controlled double blind trial
    (2017) Babiker,Rasha; Elmusharaf,Khalifa; Keogh,Michael B; Banaga,Amin S. I; Saeed,Amal M
    Background: Gum Arabic (GA) is a water-soluble dietary fiber, indigestible to both humans and animals. While GA currently does not have any therapeutic potential, it has nutritional value and some effects on metabolism of glucose and lipids. Thus, the aim of this study is to assess the effect of GA on serum level of glucose, lipids, and the BMI in type 2 diabetic patients. Methods: A double-blind randomized placebo-controlled trial took place at Academy Charity Teaching Hospital (ACTH) in Sudan between August 2014 to February 2015. The trial was conducted in type 2 diabetic patients who were on regular oral hypoglycemic drugs and had HbA1C ≥ 6.5%. Patients excluded from the study included those on insulin, any patient with a metabolic or gastrointestinal disease, and any patient with history of drug addiction and alcoholism. Other patients excluded were patients who had previous allergic reactions to GA in addition to patients who were pregnant or planned for conception within 6 months. 120 patients were invited to participate in this trial. 100 patients gave consent and were randomized to GA and placebo groups. The GA group was given 30 g of Acacia Senegal and the placebo group was given 5 g of placebo daily for 3 months. The outcomes assessed were primarily the effect of GA on glucose levels in addition to the effects on levels of lipids and BMI in type 2 diabetic patients. Results: The GA group showed significant reduction in fasting plasma glucose (FPG) and HbA1c (P<0.05) within the GA group. Moreover, GA supplementation improved lipid profiles; decreased LDL-Cholesterol by 5.95%, total Cholesterol by 8.28% and triglyceride by 10.95% from baseline levels. HDL-Cholesterol showed significant increase by 19.89% within GA group (P<0.05), BMI was decreased significantly by 2.06% (95% CI: −0.98; −0.16), P<0.05). Conclusions: Gum Arabic is a dietary supplement for improving nutrition of type 2 diabetic patients; it has demonstrated a good effect on improving their poor glycemic control. It has also shown improvement in the levels of the lipids and the BMI. Further studies are needed in obese and pre-diabetic patients to evaluate GA therapeutic potentials.
