Reducing Disease Activity of Inflammatory Bowel Disease by Consumption of Plant-Based Foods and Nutrients

Abstract: Inflammatory bowel disease is a chronic and recurring inflammatory condition of the gastrointestinal tract encompassing ulcerative colitis and Crohn's disease. Although the pathogenesis of inflammatory bowel disease remains to be fully elucidated, environmental factors such as diet are believed to play a pivotal role in the onset and management of inflammatory bowel disease. Diet is thought to play an essential role in intestinal inflammation due to its regulatory effects on the microbiota, gut immune system, … Show more

“…It is important to highlight that flavonoid compounds are poorly absorbed in the gut and their concentrations in target tissues are often too low to perform an effective antioxidant defense as reviewed by Surai [ 105 ]. For humans, consumption of various plant foods provides many phytochemicals that may significantly impact intestinal health, however, at present, no dietary recommendation for humans for phytochemicals or polyphenols exists [ 106 , 107 ].…”

“…It has been shown that anti-TNF therapy shifted the diversity of fecal microbiota in patients with IBD toward that of healthy individuals, but levels of butyrate and substrates involved in butyrate synthesis in fecal samples were significantly reduced in non-responders, which suggested the insufficient consumption of dietary fiber in non-responders [ 165 ]. Plant-based diets, low in animal protein and fat and rich in dietary fiber and polyphenols, increase microbial diversity, enhance the abundance of beneficial bacteria such as Bifidobacterium , Lactobacillus , and Faecalibacterium prausnitzii and produce beneficial microbial metabolites such as SCFAs, while inhibiting the proliferation of pathogen-associated bacteria [ 126 ], which may help to decrease the rate of nonresponse. However, plant-based diets may result in an inadequate intake of vitamin B12 and other micronutrients depending on the strictness of the diet, seasonal effects (vitamin D status) and the nutritional status of the patients, which may affect the effectiveness of plant-based diets on IBD.…”

“…The destruction of colonic epithelial barrier function is an essential factor leading to the occurrence and aggravation of inflammation ( 22 , 23 ). The tight junction (TJ) between colonic epithelial cells is an important structure to maintain intestinal barrier function.…”
