- High FODMAP Foods Could Be Aggravating Your Autoimmune Disease
Have you heard of the low FODMAP diet? It’s a type of elimination diet that is sometimes recommended to people with digestive problems. If you suffer with irritable bowel syndrome symptoms like bloating, gas or reflux, a low FODMAP diet can offer significant help. New research shows that even if you don’t experience any digestive problems, restricting FODMAPs in your diet can improve the outcome of autoimmune disease.
FODMAPs are a group of carbohydrates that are poorly digested by many people. FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols. Some people have a very low tolerance to these foods, and eating them causes a great deal of bloating and discomfort.
FODMAPs tend to have a cumulative effect, so that people typically find they become more and more bloated as the day progresses. If you want to try a low FODMAP diet, you may notice an improvement in bowel symptoms within a few days. Many commonly eaten foods are high in FODMAPs, including apples, pears, onion, garlic, cauliflower, asparagus and snow peas. Legumes and lentils are especially high in FODMAPs, so it’s no wonder that many people with IBS find they cause a great deal of gas.
A low FODMAP diet is often recommended to help with irritable bowel syndrome, but research shows it can help more serious bowel diseases such as Crohn’s disease and ulcerative colitis. Crohn’s disease and ulcerative colitis are both autoimmune diseases. They occur when the immune system attacks part of the intestines. Ulcerative colitis affects the large intestine (colon), whereas Crohn’s disease may affect the small and large intestine. They are both very common diseases and the symptoms they produce can significantly reduce quality of life. They also have the potential to become very serious and require strong medication or surgery. A few recent studies have shown that a low FODMAP diet may offer significant relief of symptoms.
Three observational studies and one randomised controlled trial have shown that a low FODMAP diet may improve gastrointestinal symptoms, including abdominal pain, bloating, diarrhea, flatulence, stool consistency and stool frequency. I see a large number of patients with Crohn’s disease and ulcerative colitis. I have written about the diet and supplement strategies I use in my book about autoimmune disease. Along with a low FODMAP diet, avoiding gluten, dairy products and healing leaky gut is essential.
Interestingly, some research has shown that eating too many high FODMAP foods can cause a flare up of an autoimmune disease that has been in remission for some time. It’s not only autoimmune conditions that affect the intestines; it can also be rheumatoid arthritis and multiple sclerosis, and probably others that haven’t been researched yet. Some FODMAPs can be more problematic than others; fructans and inulin can be most problematic. They are found in foods such as wheat, rye, onion, garlic, asparagus, bananas and chicory root. Inulin is found in many processed foods such as muesli bars and protein bars.
