Vol. 3. 0Reducing intake of foods such as apples, pears, and peaches may spell relief for individuals with irritable bowel syndrome and other conditions. Irritable bowel syndrome (IBS), functional diarrhea, and functional abdominal bloating are classified as functional gut disorders (FGDs). ![]() These conditions occur as a result of alterations in the function of the intestine and/or nervous system rather than the presence of physical abnormalities in the gut. FGDs are widespread conditions; in fact, IBS impacts about 2. American adults. 1 Although research has linked diet and symptom induction, studies have lacked evidence to support the widespread use of diet alterations for therapeutic benefit in this population. Functional gut symptoms vary from person to person, so managing them with a one- size- fits- all approach is rare. Among treatments such as modifying meal size; alcohol, fat, and fiber consumption; and lifestyle, medication use, and supplement use, the FODMAPs approach is a dietary intervention gaining attention for its potential efficacy in managing FGD symptoms.
FODMAPs is an acronym for Fermentable, Oligo- , Di- and Mono- saccharides and Polyols, used to describe a group of fermentable short- chain carbohydrates. Some evidence suggests that reducing global intake of FODMAPs to manage functional gut symptoms provides symptom relief for about 7. FGDs. 2 William Chey, MD, co–editor- in- chief of the American Journal of Gastroenterology and professor of internal medicine at the University of Michigan Health System, notes, ”It is becoming increasingly clear that the normal development and function of the GI . In fact, these two factors are linked, as the food we eat likely influences the flora that lives in our GI tract. GI symptoms like cramping, diarrhea, and particularly gas and bloating can occur as a consequence of fermentation of food by the gut bacteria. FODMAPs represent the food types that are most prone to fermentation by the gut bacteria. Taking FODMAPs out of the diet often significantly improves GI symptoms.”It’s no surprise that living with IBS can greatly impact an individual’s quality of life. Work productivity and physical well- being decline when symptoms appear. Abdominal bloating, present in 8. IBS, is one of the top reasons people seek medical care and utilize antigas medications, often to no avail. Professionals should consider a trial of the FODMAPs approach in this population to help manage symptoms. Clients who do not experience improved symptom management should continue to work in close collaboration with a dietitian and a gastroenterologist to rule out other potential dietary triggers or health issues. With the advent of sugar- free products, they found that the overuse of sugar alcohols can lead to diarrhea. The FODMAPs approach addresses the total amount of fermentable sugars consumed rather than looking at each sugar individually. This dietary intervention takes into account that there is a threshold for the amount of global FODMAPs an individual can tolerate at one time. Reiterating this key point, a leading researcher of the FODMAPs approach, Peter R. Gibson, MD, FRACP, a professor of medicine and gastroenterologist at Monash University at Box Hill Hospital in Victoria, Australia, observes, “Fructans (fructo- oligosaccharides . Those with visceral hypersensitivity or gut motility disorders appear to be more distressed by these side effects. The colonic microflora feast on the malabsorbed sugars and create gas, which contributes to abdominal bloating. Growing evidence reveals the beneficial role of minimizing FODMAPs for those with FGDs such as IBS. Meet the Family. Lactose. Lactose is the sugar found in mammalian milk such as cow’s, sheep’s, and goat’s milk. Lactose intolerance is caused by reduced or absent lactase enzyme production. Without the lactase enzyme, lactose cannot be hydrolyzed into its digestible components, glucose and galactose. Ruling out lactose intolerance with a hydrogen breath test is a desirable goal because if no intolerance is present, there is no need to modify lactose intake. Lactose intolerance presents at various thresholds from person to person. Lactose malabsorption contributes to abdominal bloating, pain, gas, and diarrhea, often occurring 3. As FODMAPs have a collective impact on GI symptoms, limiting lactose consumption (if a patient defers hydrogen breath testing or testing is not available or if a patient has documented lactose intolerance) with other fermentable short- chain carbohydrates is a good starting point with the FODMAPs approach. Encourage clients to choose low- lactose cheeses, including Swiss, Parmesan, Gouda, Colby, provolone, cheddar, Edam, Muenster, and Monterey Jack. Lactose- free milk and lactose- free cottage cheese are great sources of protein and calcium. Rice milk is another lactose- free alternative, but it contains less protein. Yogurt with live and active cultures may be easier on the intestines but, as a lactose source, should be eliminated initially and reintroduced when symptoms are better controlled to assess tolerance. Individuals should avoid lactose- rich foods such as ice cream, milk, condensed milk, and most soft cheeses (eg, cottage cheese), as they are not FODMAP friendly for those with lactose intolerance. Fructose. Fructose, most commonly known as fruit sugar, is also found in honey, high- fructose corn syrup (HFCS), agave, sucrose (table sugar) bound to glucose, and fructans. Conversely, foods with excess fructose compared with glucose, such as apples, pears, and mangoes, will likely trigger abdominal symptoms. Increased use of agave as an alternative to sugar may also contribute to FGD symptoms. Jane Muir, Ph. D, head of research in the department of medicine at Monash University and one of the prominent researchers in this area, notes, . Fructose malabsorption is defined as the incomplete absorption of fructose in the small intestine, followed by the delivery of fructose to the distal small bowel and colon, where it contributes to rapid fermentation and resultant abdominal bloating. The absorptive capacity of fructose varies from person to person. Like lactose intolerance, a hydrogen breath test can detect fructose malabsorption. Fructose is absorbed via a low- capacity, carrier- mediated facilitated diffusion GLUT5. A dietary load of 5. Differentiating fructose malabsorption from hereditary fructose intolerance is essential, as fructose intolerance requires total avoidance of fructose. Even when fructose is in the presence of glucose, individuals likely have a threshold for total fructose intake. Limiting the dietary load of fructose is another potential (yet not fully evaluated) component of the FODMAPs approach. Based on clinical observations, avoiding foods and beverages that contain greater than 0. To be prudent, patients should limit consumption to one serving of FODMAP- friendly fruit per meal. They should also consume ripe fruits, as ripeness affects the amount of fructose. Firm, less- ripe fruit tends to contain more fructose. Because HFCS is present in so many foods in the United States, fructose intake is likely at an all- time high. HFCS can be created with various amounts of fructose and glucose but most often contains 5. In many cases, individuals can tolerate small amounts of HFCS, as the amount of excess fructose is not great. Encouraging clients to eliminate or limit products made with HFCS, such as soda, barbeque sauce, and cereals, would be a conservative approach to minimizing their fructose load. Fructans. Fructans are oligosaccharides made of fructose molecule chains that are completely malabsorbed because the small intestine lacks hydrolases to break their fructose- fructose bond. For this reason, fructans can contribute to bloating, gas, and pain. Wheat accounts for the majority of people’s fructan intake. Fructan consumption of greater than 0. Inulin and FOS sources of fructans, are added to many foods to enhance their fiber content. Patsy Catsos, MS, RD, author of IBS- Free at Last, notes, . While this makes sense in general, these food additives are sometimes poorly tolerated by people with IBS. The human body lacks the enzymes to hydrolyze them into digestible components, so they are completely malabsorbed. Consequently, galactans can contribute to gas and GI distress. Dietary sources of galactans include lentils, chickpeas, kidney beans, black- eyed peas, broccoli, and soy- based products. Polyols. Polyols are also known as sugar alcohols. Most are too large for simple diffusion from the small intestine, creating a laxative effect on the GI tract. They are found naturally in some fruits and vegetables and added as sweeteners to sugar- free gums, mints, cough drops, and medications. Polyols produce osmotic diarrhea when consumed in quantities above an individual’s personal threshold or in combination with other FODMAP sources. Sugar alcohols have varying effects on the bowel. A polyol’s molecular size affects absorption. Erythritol, a four- carbon polyol, is well absorbed, while many six- carbon polyols are not. Some fiber supplements contain both sorbitol and inulin, making them a “no- go” on this diet. Others contain methylcellulose, a 1. FODMAP friendly. Vitamin water containing crystalline fructose is not FODMAP friendly, while many beverages sweetened with aspartame are well tolerated. Final Thoughts. Despite its apparent complexity, the FODMAPs approach can be effective when delivered by a dietitian skilled in its intricacies. Patient compliance with this diet is very good, likely due to quality- of- life improvements.
