Many people with IBD restrict foods when in a flare-up, but more calories are needed to prevent losing too much weight. A physician can help you understand weight loss and how much is too much. One important part of an IBD flare-up diet is protein. Sources of protein to eat during an IBD flare-up include lean meats, fish, eggs, and nut butters. It's important to avoid fattier cuts of meat, as well as meats that are low-quality or are heavily spiced. Nut butters should be smooth and free of pieces of nuts "crunchy" and eggs should be cooked without adding fats not fried.
Fruits with a lot of seeds might be difficult during a flare-up and should be avoided in most cases, which includes a lot of berries. Melons, however, are going to be a good choice for a fruit that is easy to digest. Some of the fruits that are going to be more friendly for people in an IBD flare-up include bananas, watermelon, cantaloupe, papayas, and honeydew.
Eat these fruits when they're quite ripe and with all the seeds removed. Herbal teas are comforting during a flare-up and can break up the monotony of drinking plain water. Teas should be naturally caffeine-free and without any additives. Artificial sweeteners can cause diarrhea or stomach upset in some people, so those should be avoided if that's the case.
There are a variety of nutritional supplements on the market that can be found in grocery and drug stores. They do tend to be pricey, but they can add much-needed nutrients to the diet during a flare-up. A gastroenterologist can recommend a particular brand and offer advice on how often they should be used. Liquid nutritional supplements shouldn't be used as the sole source of calories, however, as they are only meant to augment the diet until more foods can be added. Coffee has a reputation for making people "go. Foods made with cow's milk can cause problems for some people, which is why it's often recommended that people with IBD avoid them.
A gastroenterologist can help in diagnosing lactose intolerance , and for those who do have an intolerance and find milk products cause gas and pain or other symptoms, avoiding those foods is the best idea. This includes foods like a glass of milk, cheeses, ice cream, pudding, and yogurt. Some foods will have a lower lactose content, or may even contain only traces of lactose, such as yogurt and aged cheeses such as cheddar, Colby, Parmesan, and Swiss. IBD-associated gut dysbiosis is accompanied by functional changes in the gut microbiota that affect its ability to ferment dietary fibers.
The abundance of butyrate-producing bacteria, such as Roseburia hominis and Faecalibacterium prausnitzii , is decreased in IBD patients 11 , , and, therefore, fecal SCFAs levels are lower in IBD patients compared to controls On the other hand, recent clinical trials did not demonstrate overt therapeutic benefits associated with butyrate enemas in UC patients , These results suggest that IBD patients might have functional impairments involving butyrate utilization in addition to its impaired generation, likely due to gut dysbiosis.
For instance, several studies have reported that butyrate oxidation and the expression of genes involved in butyrate oxidation are diminished in the intestinal mucosa of IBD patients — , indicating that butyrate cannot be used properly in the inflamed gut. Moreover, butyrate uptake by colonocytes is impaired in IBD patients. Although numerous animal studies have reported that dietary fiber supplementation attenuates intestinal inflammation — , only limited evidence is available from clinical trials involving IBD patients Prebiotic fibers might promote the growth of protective members of the gut microbiota.
However, there is no study that provides statistically significant evidence for the efficacy of prebiotic fibers as treatment for IBD It implies that fiber treatment is not effective for active IBD. Regarding this notion, it has been reported that intestinal inflammation down-regulates carbohydrate metabolism in the gut microbiota 11 , Thus, it is possible that gut microbes are not able to utilize supplied fibers efficiently in the inflamed gut.
Consistently, consumption of a high fiber diet does not attenuate colitis, while pretreatment with the same diet can prevent the development of colitis Thus, metabolic activities of the microbiota, which might be altered as a result of disease, may determine the usefulness of administrating prebiotic fibers to IBD patients. In addition to disease status, the initial composition of the microbiota may influence the efficacy of dietary fiber treatment.
For example, dietary fiber can improve postprandial glucose metabolism in healthy individuals, but they are divided into responders and non-responders The abundance of Prevotella , a bacterial genus capable of digesting fibers, is higher in responders compared to non-responders. In other words, a high fiber diet is not beneficial in individuals who do not have sufficient numbers of fiber-degrading bacteria in their gut microbiota.

Taken together, personalized nutritional management will likely be a key component of any successful therapeutic approach for IBD since intestinal inflammation results in both compositional and functional changes of the gut microbiota. Several dietary therapies that eliminate specific carbohydrates have been developed and evaluated for induction of remission, maintenance and improvement of functional symptoms in IBD.
Symptoms of IBD commonly include abdominal pain, discomfort, rectal bleeding, and a change in stool consistency and frequency during active periods. However, similar gastrointestinal symptoms can also be observed during periods of remission, even in the absence of clinical inflammation These functional-like gastrointestinal symptoms are negatively correlated with the quality of life QOL experienced by IBD patients Naturally, a more effective control of functional-like gastrointestinal symptoms is needed to improve the QOL of IBD patients.
Dietary therapies for these functional-like gastrointestinal symptoms have recently been developed. A randomized, double-blind, placebo-controlled, cross-over study has revealed that the administration of fructans, unlike galacto-oligosaccharides or sorbitol, exacerbates functional-like gastrointestinal symptoms in quiescent IBD Whereas, most carbohydrates are completely digested and absorbed in the small intestine, some carbohydrates are not. Unabsorbed carbohydrates, such as fructose, polyols, and lactose, alter intestinal osmolality and increase water content in the small intestine.
Other unabsorbed carbohydrates, including fructans and galacto-oligosaccharides, are fermented by the bacteria in the colon, leading to gas production. High levels of luminal water and gas result in luminal distension, thereby causing functional-like gastrointestinal symptoms. In an animal study, a high FODMAP diet increased intestinal permeability and altered the composition of microbial communities, leading to increased luminal levels of LPS Dietary intervention is an exciting topic in the current IBD research.
Bowel Disease: Changing Your Diet | Kaiser Permanente
The Western diet is characterized by high intake of fats. There is evidence that links increased fat intake to the pathogenesis of IBD. Most fatty acids, except for linoleic acid and alpha-linolenic acid which are essential fatty acids, can synthesize in the body. Fatty acids are important energy sources and membrane constituents, and their biological activities influence both the immune system and the gut microbiota.
A number of studies have revealed that high-fat diets change the composition of the gut microbiota and impair intestinal barrier function, resulting in intestinal and systemic inflammation — Furthermore, consumption of a diet containing high levels of fat and sugar promotes the colonization of adherent-invasive E. A recent systematic literature review of epidemiological data has shown that high dietary intakes of total fats, SFAs, omega-6 n-6 and PUFAs are associated with an increased risk of both CD and UC Similar to amino acids and carbohydrates, abnormal fatty acid profiles and metabolism are observed in the blood and intestinal mucosa of IBD patients On the other hand, dietary supplementation with specific fatty acids can improve perturbed fatty acids profiles and intestinal inflammation We summarize the roles of fatty acids in the pathogenesis and treatment of IBD.
SFAs, mainly myristic acid, palmitic acid, and stearic acid, are found in animal fat-containing products, such as meat, butter, whole milk, and other dairy products. Although a connection between saturated fats and the risk of IBD has been uncovered by small case—control studies, prospective cohorts have not identified a statistical association, suggesting the relationship is more complex.
In animal studies, a diet high in SFAs induces colonic inflammation, including increased expression of pro-inflammatory cytokines and enhanced intestinal permeability in a microbiota- or TLR4-dependent manner — Similarly, a diet high in SFAs exacerbates intestinal inflammation in experimental models of colitis , A milk-derived diet high in saturated fats, unlike a diet high in polyunsaturated fats, promotes the expansion of a sulphite-reducing pathobiont, Bilophila wadsworthia , and aggravates Th1-mediated colitis in IL deficient mice Milk-derived fat promotes taurine conjugation of hepatic bile acids, thereby leading to the accumulation of sulfur that aids the growth of B.
In a murine model of DSS-induced colitis, the level of a saturated fat 1-stearoyl-sn-glycerophosphorylcholine stearoyl-LPC in the blood is increased compared to control mice, whereas the unsaturated fat 1-oleoyl-sn-glycerophosphorylcholine oleoyl-LPC is decreased following DSS treatment. The perturbation of the lipid serum profile is caused by decreased expression of stearoyl-CoA desaturase 1 SCD1 in the liver.
SCD1 is an enzyme found in the endoplasmic reticulum. It is responsible for the biosynthesis of oleic acid and palmitoleic acid from stearic acid , and palmitic acid , respectively Consistently, SCD1-deficient mice are more susceptible to DSS and exacerbated colitis can be ameliorated by means of oleic acid supplementation MUFAs are classified as fatty acids containing a single double bond.
Oleic acid, the most common omega-9 MUFA, is found in various vegetable oils, such as olive oil and canola oil. The levels of MUFAs, including oleic acid, are significantly reduced in IBD patients compared to control subjects, both systemically blood and locally intestinal mucosa , Epidemiologically, the Mediterranean diet containing high levels of MUFAs, especially oleic acid, is well-recognized for its beneficial effects on metabolic syndrome and cardiovascular health A large prospective cohort study has demonstrated that dietary oleic acid intake is inversely associated with UC development Several animal studies have consistently demonstrated that supplementation of oleic acid or olive oil attenuates intestinal inflammation in DSS-induced colitis , PUFAs are classified into omega-3 n-3 and n-6 families.
These two families are thought to have different effects on inflammation. Conventionally, n-6 PUFAs are considered to be pro-inflammatory.
Linoleic acid, the major PUFA in the diet, is converted to arachidonic acid, a precursor of inflammatory mediators such as prostaglandins and leukotrienes N-6 PUFAs are incorporated into phospholipids found in cellular membranes. Arachidonic acid is a primary target for PLA2 and is converted to inflammatory mediators involved in pro-inflammatory cell signaling events. The levels of PLA2 are elevated in the mucosal biopsies of CD and UC patients , resulting in increased hydrolysis of arachidonic acid and the subsequent generation of inflammatory mediators.
In contrast, n-3 PUFAs appear to be critical for the suppression of inflammation. Likewise, pro-resolving mediators are generated from n-3 fatty acids via several enzymatic reactions RvE1 inhibits leukocyte infiltration and IL production by dendritic cells and macrophages , Although previous studies have examined the effect of n-3 fatty acid supplementation in prevention and treatment of IBD, the outcomes were inconsistent in both human IBD and animal models of colitis.
In the animal studies, supplementation with n-3 fatty acids found in fish oil attenuated intestinal inflammation , , whereas another study showed that n-3 fatty acids exacerbated colitis This disparity may have been caused by various confounding factors, such as control diet, administration period and sensitivity to oxidation. Another report demonstrated that fat-1 transgenic mice are protected against DSS-induced colitis Since fat-1 transgenic mice have increased endogenous levels of n-3 PUFAs, the protective phenotype observed in this mouse strain may be due to n-3 PUFAs In human IBD, a systematic review does not support the notion that supplementation of n-3 fatty acids can induce and maintain remission of IBD The latest Cochrane review has reached a similar conclusion Interestingly, several studies have demonstrated that different genotypes may be associated with the variable response to nutritional intervention with n-3 PUFAs.
Since fatty acid utilization may vary depending on the genetic background, personalized nutritional management is likely required to maximize the efficacy of n-3 PUFAs supplementation in IBD. Phytochemicals are a wide range of natural compounds found in plants. Accumulating evidence suggest that phytochemicals have beneficial effect on several chronic diseases A number of polyphenols, including flavonoids, phenolic acids, stilbenes, and lignans, have been shown to influence the gut microbiota and intestinal immunity. For example, curcumin, a hydrophobic polyphenol derived from Curcuma longa , displays a wide variety of biological functions, such as anti-inflammatory, anti-cancer, and anti-oxidant activities Polyphenols including curcumin are not efficiently absorbed from the small intestine, and therefore polyphenol complexes contained in diet have limited bioavailability Given this evidence, a large portion of unabsorbed polyphenols are likely transported to the large intestine where they interact with the colonic gut microbiota.
Of note, the gut resident bacteria are capable of catabolizing polyphenols and degrading them into small fragments For instance, curcumin is converted into tetrahydrocurcumin by curcumin-converting enzyme purified from E. Curcumin-derived tetrahydrocurcumin can prevent colitis and colitis-associated colon cancer in mice , Recent epidemiological study reported a potential association of polyphenol in CD Moreover, clinical trials show that curcumin supplementation is effective for the induction and maintenance of remission in UC patients , Recent widespread use of processed food increases consumption of food additives.
Emulsifiers are complex molecules that are incorporated into most processed foods to enhance texture and stability. It has been implied that the increased consumption of emulsifier is associated with IBD pathogenesis In recent studies, the consumption of dietary emulsifier disrupted host-microbiota interaction and promoted intestinal inflammation and colon carcinogenesis , Although precise mechanism remains incompletely understood, dietary emulsifiers foster the blooms of mucolytic bacteria, such as Ruminococcus gnavus and Akkermansia muciniphila Importantly, the negative impact of dietary emulsifiers is not observed in GF mice, suggesting that the compositional and functional modulation of the gut microbiota by emulsifiers play a key role in their adverse effect Other food additives, for example artificial sweeteners, also induce gut dysbiosis , The consumption of artificial sweeteners promotes the expansion of Proteobacteria and increases the infiltration of bacteria into the ileal lamina propria in CD-like ileitis model mice These studies suggest that many food additives may be associated with the risk of IBD.
In fact, epidemiological and clinical studies reported that processed meats and beverages are risk factors for the onset and relapse of IBD , However, it is difficult to ascertain whether food additives are risk factors for developing IBD, because most food frequency questionnaires cannot fully evaluate the consumption of food additives. The relationship between dietary nutrients and intestinal homeostasis is complex. It is influenced by a myriad of interactions between host immunity, the intestinal epithelium and the gut microbiota.
Moreover, intestinal inflammation changes cellular and microbial metabolisms, adding another layer of complexity to an already complex system Table 2. The demand for certain nutrients necessary for the maintenance of intestinal homeostasis is likely altered in IBD. The scarcity or overabundance of some nutrients can disturb intestinal homeostasis even further, thus exacerbating the disease. Genetic polymorphisms also influence the efficacy of nutritional intervention.
Thus, an in-depth knowledge of a patient's genetic predispositions, gut microbial compositions, disease activity and type i. Table 2. Changes of dietary nutrient availavility in the host and gut microbiota of IBD.

If you are considering altering your diet, we recommend that you do so under the guidance of a qualified dietitian. Locate your nearest Accredited Practising Dietitian at www. However, adjusting your diet can help manage some of your symptoms, and can help IBD medications work better.
During flare-ups of disease, some people find that a bland, low-fibre diet is easier to tolerate than one that contains high-fibre or spicy foods. Low-fibre diets are those that avoid fruits and vegetables, nuts, raisins, seeds, bran and whole grains. These diets tend to stimulate less secretion of intestinal fluids and cause less contraction in the small and large intestines and may help to control symptoms such as abdominal cramps and diarrhoea.
A dietitian is a vital member of your clinical team and will assist you to work out a dietary plan that is just right for you.
