Investigating of Moringa Oleifera Role on Gut Microbiota Composition and Inflammation Associated with Obesity Following High Fat Diet Feeding

Abstract

AIM:The alteration in the gut microbial community has been regarded as one of the main factors related to obesity and metabolic disorders. To date, little is known about Moringa oleifera as a nutritional intervention to modulate the microbiota imbalance associated with obesity. Therefore we aim to explore the role of aqueous Moringa oleiferous leaf extract on Lactobacilli and Bifidobacteria in high-fat diet-induced obesity and to investigate whether any restoration in the number of caecal Lactobacilli and Bifidobacteria could modulate obesity-induced inflammation.METHODS:Young Swiss albino mice were divided into three groups according to their diet. Two of them were fed on either high fat diet or high fat diet+aqueous extract of Moringa oleifera leaf, while the third group was fed on the control diet. Bacterial DNAs were isolated from the mice digesta samples for bacteria level estimation using Quantitative real-time polymerase chain reaction along with serum interleukin-6 and lipid profileRESULTS:Compared to the normal control mice, high-fat diet feeding mice showed significantly reduced intestinal levels of Bifidobacteria, and increased body weight, interleukin 6, and levels of Lactobacilli. Upon treatment with Moringa oleifera, body weight, interleukin 6, and both bacteria levels were significantly restoredCONCLUSIONS:Our findings suggest that Moringa oliefera aqueous leaf extract may contribute towards the pathophysiological regulation of weight gain, inflammation associated with high-fat-induced-obesity through gut bacteria modulation.

Mediterranean Diet to Prevent the Development of Colon Diseases: A Meta-Analysis of Gut Microbiota Studies

“…The Proteobacteria phylum is a marker of gut dysbiosis [ 68 ], and one of the phyla increased along the axis. It has been associated with a high-fat diet and obesity in mice [ 69 ], with consumption of animal fat [ 70 ], and most importantly, with a colonic mucosa more easily penetrated by other bacteria [ 71 ]. This may explain the low abundance observed in MD, where animal fat consumption is greatly diminished, but not in PD, which includes several animal-derived products.…”

Therapeutic influence of some dietary articles on gut microbiota in the pathogenesis of rheumatoid arthritis (Amavata) – A review

“…Moringa oleifera leaf extract in a study showed that it could serve as a gut modulator in obesity‑induced dysbiosis, thus proving a significant correlation between increased levels of bifidobacteria and reduced leakiness in the gut. [ 23 ]…”

Gut Microbiota and Atherosclerosis—Focusing on the Plaque Stability

“…Diet ( 139 , 140 ) has shown to be closely associated with the composition and diversity of gut microbiota ( Figure 2 ). De Filippo et al once conducted a study that aimed to find whether there are some differences between the gut microbiota of children (BF) fed with traditional rural African diet, characterized with low in fat and animal protein and rich in starch, fiber, and plant polysaccharide and children (EU) eating a typical western diet high in animal protein, sugar, starch, and fat and low in fiber.…”
