. Case example This case is a case showing that even a severe restriction in energy intake leads to improvements in the clinical signs and symptoms of Crohn’s disease, after a long-term vegetarian diet, which included an increase in protein intake, no animal products, and no cheese. The diet consisted in whole grain bread from white whole wheat bread, low-fat butter on whole wheat bread and whole milk on whole milk, and vegetable soup. An improvement in clinical symptoms was observed in 12.9 years without a remission.
. Scientific explanation Based on the aforementioned studies, we can conclude that a vegetarians diet, especially a vegetarian diet which contains a diet pattern low in animal products and high in plant foods, has positive effects on several aspects of the gut microbiome and may lead to improvement of many inflammatory indicators, including gut permeability, intestinal permeability and inflammation, inflammatory bowel disease (IBD) and colitis/ulcerative colitis. Moreover, a vegetarian diet may have beneficial effects on the liver function and may reduce oxidative stress associated with IBD and related disorders, including fatty liver, insulin resistance, hyperlipidemia, hyperglycemia and hypoglycemia, hepatic steatosis and lipid peroxidation in a variety of different organs, including the liver and the kidneys. Although the benefits of a vegetarian diet on the human gut microbiome have not been adequately studied yet, these beneficial effects may be related in part to the reduction of gut permeability through the improvement of the permeability of the small bowel.
3. Potential mechanisms of action of a vegetarian diet in the treatment of IBD The role of the gut microbiome in the etiology of several gastrointestinal diseases has not been determined. Therefore, the role of gut microbiome in IBD has not been well defined. Nevertheless, there is clear evidence that various gut diseases, even in the absence of diarrhea or a fever, are related to dysbiosis of the gut microbiome. Thus, diet-microbe interactions may play a role in the development of certain diseases. Dietary patterns that are associated with increased consumption of fruit and vegetables, fiber-rich foods, legumes, seeds and low-fat dairy products are also associated with less disease and, thus, with beneficial effects on the gut microflora through improving bacterial diversity, preventing the incidence of food poisonings, colon cancer and many other inflammatory diseases and diseases of the gastroenteric tract, with the possible protective effect of the reduced risk of colon cancer. In the intestinal mucosa, the composition and structure of both resident and non-resident bacteria in the fecal sample and the abundance of gut commensal bacteria varies according to the diet. The composition of resident fecal bacteria is significantly altered in persons with a reduced gut flora due to antibiotic treatment of the human intestine. The low-cost commercial microbiome tests measure, among other things, the abundance of Bifidobacterium in the gut microbiota by performing pyrosequencing or restriction fragment length polymorphism, which could be done at a small cost (Figure 2). However, even after taking into account these limitations, these tests give a good picture of the microbial composition of the intestinal microbiota and are a valuable tool towards diagnosis of gastrointestinal diseases.
