Background Chronic kidney disease (CKD) poses significant health challenges worldwide, with limited effective natural therapies targeting its progression through antioxidant mechanisms. Although gum acacia (GA) has shown general metabolic benefits, its dose-dependent therapeutic efficacy in CKD and its effects on key antioxidant pathways remain unclear. This study aimed to evaluate the therapeutic potential of gum acacia (GA) in an adenine (AD)-induced CKD rat model. Methods Rats were randomly assigned to five groups (n = 7 per group): Group I (control), Group II (GA at 600 mg/kg for 14 days), Group III (AD at 600 mg/kg for 10 days), and Groups IV and V (AD for 10 days followed by GA at 300 mg/kg or 600 mg/kg for 14 days). All treatments were administered daily by oral gavage. Results AD treatment led to significant reductions in body weight, increased relative kidney weight, and disrupted kidney and liver function markers, including elevated urea, creatinine, ALT, GGT, and glucose levels. AD also increased oxidative stress, altered blood parameters, and caused downregulation of APRT mRNA expression and upregulation of FGF-23 expression. GA treatment at both doses (300 and 600 mg/kg) mitigated these abnormalities, significantly improving kidney and liver function, enhancing antioxidant status, and ameliorating hematological and metabolic disturbances. The most pronounced effects were observed with the 600 mg/kg dose. Conclusions Building on prior indications of GA’s benefits, our findings offer new and comprehensive evidence of its dose-dependent therapeutic effects in adenine-induced CKD, particularly through the modulation of oxidative stress pathways and regulation of APRT and FGF-23 expression. These insights lay the groundwork for future clinical translation.

Commercial acacia gum (AG) used in this study is a premium-grade free-flowing powder. It is a gummy exudate composed of arabinogalactan branched polysaccharide, a biopolymer of arabinose and galactose. Also known as food additive, acacia gum (E414), which is presently marketed as a functional dietary fiber to improve overall human gut health. The health effects may be related to the luminal pH regulation from the short-chain fatty acids (SCFA) production. Studies suggested that amylolytic and butyrogenic pathways are the major factors determining the SCFA outcome of AG in the lower gut. However, the primary bacteria involved in the fermentation have not been studied. This study aimed to investigate the putative primary degraders of acacia gum in the gut ecosystem. Isolation and identification of gum-fermenting bacteria were performed through enrichment culture fermentation. The experiment was conducted in an anaerobic chamber for 144 h in three stages. The study was conducted in triplicate using an anaerobic chamber system. This culture system allows specific responses to support only bacteria that are responsible for gum fermentation among the gut microbiota. Five bacterial strains were isolated and found to be gum-fermenting bacteria. Based on the 16s RNA sequence, the isolates matched to butyrate-producing Escherichia fergusonii, ATCC 35469.

Gum Arabic (Acacia Senegal) Augmented Total Antioxidant Capacity and Reduced C-Reactive Protein among Haemodialysis Patients in Phase II Trial

Acacia senegal (Linn) Wild a member of Mimosaceae is a small tree of 3-6m in height with umbrella-shaped crown. It is a typical tree of Sahel in Africa from Senegal to red sea and essentially limited to the area between 110 and 160 North, with a wide range of rainfall 100 to 800mm. It spread widely in tropical Africa from Mozambique, Zambia to Somalia, Sudan, Ethiopia, Kenya, Tanzania and Nigeria, and in South Asia in India and Pakistan. In India it is a typical tree of arid regions with a low rainfall of 100-250mm. It is drought resistant and tolerates prolonged dry period of 10-11 months, with maximum temperature reaching 500C with strong winds, but susceptible to frost. It occurs mostly on sand stones and skeletal soils and widely distributed as interspersed species in most of the rangelands and grasslands in arid and semi-arid regions of India. World’s 90% gum Arabic is produced from Acacia senegal. The quality of gum is very superior as compared to gum from any other species of Acacia (Andreson, 1990). Nearly 90% of gum Arabic is produced by Republic of Sudan especially from (Kordafan). Production of gum Arabic is meagre in India, and contribution to the world production is negligible. The total annual output of gum Arabic is only 800 Mt compared to world production and consumption of 60,000-70,000 Mt. The domestic production is insufficient even for domestic consumption and more of it is imported from Sudan and Nigeria to meet India's requirements. Gum exudes from cracks in bark of trees, mostly in the dry season. In Sudan the annual yields from young trees ranges from 188 to 2856 g (av. 0.9 kg), and from older trees, 379 to 6754 g (av. 2.0 kg). In India, however, the productivity is low varying from 175 to 550g tree-1 year-1. The main gum producing regions of India where natural as well as planted stands of A. senegal occur are in desert and arid region of Rajasthan, Gujarat, Haryana, and Punjab. The gum yield from various Acacia trees in their natural habitat is very poor. In arid and semi-arid region of India, particularly in Rajasthan, Gujarat, Haryana, Punjab and Bundelkahand, there is a good scope for extending area for large- scale plantation for production of gum Arabic. The area covered under forest, barren and uncultivable, pasture, oren (temple lands) and community grazing land etc, can be used for

The use of ionizing radiation exposure increases oxidative stress especially for cancer patients. Therefore, there is a critical need to develop antioxidants that prevent oxidative stress damage. Arabic gum is an antioxidant and anti-inflammatory mediator. The function of Arabic gum (Acacia arabica) in protecting against injury to the liver tissue caused by 5 Gy whole-body γ-irradiation was studied using histopathological and ultrastructure techniques.Materials and Methods: Forty-eight male albino Sprague–Dawley rats were divided into four groups: control (C), irradiated (R): rats were exposed to 5 Gy gamma-radiation as a single dose for 10 min., Arabic gum (AG) : rats were treated orally with 25 mg/kg/day AG for 3 weeks and AG + R. Experimental rats were treated orally with 25 mg/kg/day AG for one week before, and three weeks after irradiation, and were sacrificed after 7 and 21 days of irradiation. Results: Gamma radiation was observed to affect the histopathology and ultrastructure of liver tissues, such as distorting the central vein with a highly dilated and delaminated endothelial lining, lymphocytic infiltration, many vacuolated hepatocytes with increased signs of karyolysis and pyknosis in hepatocytes nuclei, faint electron outer and inner membranes of mitochondria and increases in collagen fibers. On the other hand, treatment with AG ameliorated all of the previous histological and ultrastructure changes. Arabic gum showed a radio-protective effect and improved liver structure indicating that pre-treatment with Arabic gum is effective in lowering the incidence of the hepatic histopathological changes induced by gamma-radiation with remarkable restoration of normal hepatocytes structure.

Lipid emulsification is a technique that is being explored for improving the bioavailability of omega 3 (n-3) long chain (LC) fatty acid (FA). The nature of the emulsifiers can differently impact the lipid bioavailability via a modification of the lipolysis step. Among natural emulsifiers, gum acacia (GA), an indigestible polysaccharide, provides protective encapsulation of n-3 by forming a specifically crown-like shape around lipid drops, which could also impact the digestion step. Despite the interest in lipolysis rate, the impact of GA on lipid bioavailability has never been explored in a complete physiological context. Thus, we followed in a kinetics study the n-3 bioavailability in rat lymph, orally administered DHA-rich oil, formulated based on GA compared to the bulk phase form of the oil. The AUC values were significantly improved by +121% for total TG and by 321% for n-3 PUFA, specifically for EPA (+244%) and for DHA (+345%). Benefits of GA have also been related to the transport of FA in lymph, which was 2 h earlier (Tmax = 4 h), compared to the Tmax (6 h) obtained with the bulk phase oil. All the data showed that GA is one of the most favorable candidates of natural emulsifiers to improve n-3 bioavailability and their rate of absorption for health targets.

This double-blind, controlled, randomized, three-way cross-over study evaluates the effect of 40 g (D1 group) and 20 g (D2 group) of acacia gum (AG) versus no treatment (NT group) on post-prandial glucose (PPG) levels in normal-weight and overweight subjects. Additionally, post-prandial insulin (PPI) levels as well as the safety and tolerability of gum acacia were assessed. 35 healthy subjects aged 25 - 60 years, body mass index 18.5 kg/m2 - 29.9 kg/m2, received one treatment of 20 g, 40 g, or 0 g of AG each. Glucose and insulin values were determined at -15 min and prior to the intake (time “0”) as well as 15, 30, 45, 60, 90 120, and 180 min after the “0 min” blood draw. The mean PPG levels were lower (34% in D1 group, p = 0.003; 35% in D2 group, p = 0.005) than in the NT group. PPI concentration was statistically significantly lower at all time points except baseline in both treatment groups compared to NT groups. Global benefit and tolerability were rated as “very good” or “good” by 100% of subjects in the treatment groups. This study provides robust evidence of the significant benefits of AG consumption on PPG and PPI levels in healthy subjects. Moreover, very good tolerability was demonstrated.

Acacia gum (AG) is a branched-polysaccharide gummy exudate that consists of arabinose and galactose. The traditional practice in African-Middle Eastern countries uses this gum as medicine. Traditional use of AG is to treat stomach disease, which can be a potential functional food. In this research, commercially available AG from Acacia senegal and Acacia seyal was investigated as the prebiotic. The experiment employed a pH-controlled in vitro colon model inoculated with human fecal microbiota to mimic the human colon. Fermentation samples at 0, 6, 12, and 24 h were brought for short-chain fatty acid (SCFA) analysis using high-performance liquid chromatography and bacterial enumeration via fluorescent in situ hybridization. Results showed that AG significantly promotes Bifidobacteria proliferation similar to fructo-oligosaccharides (FOS) while inhibiting the Clostridium histolyticum group, commonly associated with gut dysbiosis. Acetate, propionate, and butyrate showed a similar trend to FOS (p > 0.05). The AG shows potential against gut dysbiosis, as it promotes gut-probiotics, through modulation of microbial population and SCFA production, especially butyrate.
