In a group of 19 patients with inflammation, and an exaggerated immune response characterized active UC (mild-moderate disease severity) administered inulin by imbalanced anti-inflammatory and proinflammatory cytokines. for 2 weeks in addition to the 3g/daily of mesalamine, a significant Proinflammatory cytokines such as IL-1, IL-6, IL-12, IFN-gamma reduction in calprotectin (a fecal inflammatory marker increased and TNF-alpha are increased with lowered anti-inflammatory in IBD) compared with the placebo control group was observed and regulatory cytokines like IL-10 and TGF-beta.

UC in general shows more diagnosed with IBD later in life, aside from regular check-ups with significant benefit from prebiotic support compared with CD. gastroenterologists between procedures and to monitor efficacy of pharmaceutical interventions, many adults have questions about Probiotic support is widely considered a gold-standard intervention their specific needs and are looking for additional support. However, in both conventional and integrative medicine for both active many patients are reluctant to seek out integrative healthcare as they and remission phases of IBD, with benefits of the most popular are concerned they will be encouraged not to take their medications investigated strains summarized in Table 1.

Prebiotic supports (i.e. oligofructosaccharides and/or inulin found for diarrhea-control and initiating remission (Ewaschuk 2010). in chicory, wheat, onions, bananas) encourage growth of beneficial
bacteria and have the capability of skewing directional growth of
probiotic strains which confer specific host benefits (Bouhnik 2004,

benefits include providing energy sources for intestinal bacteria to
ferment into short chain fatty acids (SCFA) (Looijer-van Langen

While patients with IBD have steatorrhea and microbes in the intestines and food consumption (Asakura 2008). fat-soluble vitamin malabsorption, fish oil supplementation should be a top priority in integrative support of IBD (Hartman Along the same vein, lactose intolerance and lactose malabsorption 2009). A selection of research groups in comparison of N-3, have a strong amount of research support with correlations to N-6 and N-9 oil usage for IBD across 10 years has been quickly worsening IBD, especially CD compared with controls (Szilagyi summarized in Table 3 to further confirm the absolute necessity 1998).
