Are you following a low FODMAP diet to improve your gut health? Some hidden FODMAPs might not show up on the popular lists. Here are some of the lesser-known FODMAPs that could be preventing you from achieving your optimal gastrointestinal function:
Chicken Wings
Chicken is generally not considered a FODMAP, but the wings might upset your gut more than the breast meat. This is because there is a higher bone and cartilage-to-meat ratio. Specific sugars (polysaccharides) leach out from the bones and cartilage into the meat, contributing to its flavor. If you are on a low FODMAP diet, abstain from chicken wings for at least a week before you add them back into your diet, and pay attention to your digestion for the next twenty-four hours. Are you experiencing loose stools, cramping, or stomach pain? If so, you may have uncovered a sensitivity to the polysaccharides in the connective tissues.
Collagen Protein Powder
When looking at a low FODMAP diet, many people overlook proteins. Unfortunately, proteins can also be fermentable (the “F” in FODMAP) and could harm your digestion. This is especially true for collagen protein, especially for people with Pseudomonas overgrowth, who should avoid collagen protein powder altogether. Consider switching to an ultra-low lactose whey protein isolate if you fall into this category.
Shellfish
Shellfish have an exoskeleton made from a material called chitin. Like chicken wings, when shellfish are cooked, compounds from the chitin leach into the meat, giving the shellfish their delicious flavor. Unfortunately, their exoskeletons, which are mostly composed of N-acetyl glucosamine, also contain glucans, which can upset your digestion if you are sensitive to high FODMAP foods. If you follow a low FODMAP diet, avoid the shrimp cocktail until your gut is optimized.
Cheese
Cheese is becoming ubiquitous in the American Standard Diet (SAD). You can find it on sandwiches, pizza, tacos, and salads. It is becoming difficult to find a fast food entre that isn’t topped with cheese, but hopefully, if you are on a low FODMAP diet, you are avoiding fast food anyway. Cheese contains proteins called caseins, which are slow to digest. Digestive enzymes have a harder time breaking down protein from cheese into peptides and amino acids, and the fat content makes it even more difficult! If protein passes through the small intestine undigested, it can be a massive issue for your digestive health. Protein fermentation in the large intestine and colon could efficiently run your day, so please avoid cheese if you are on a low FODMAP diet.
Toothpaste
More and more “natural” toothpastes use polyol (the “P” in FODMAP) called xylitol. You might think I don’t swallow my toothpaste; I spit it out in the sink. However, xylitol is highly reactive to opportunistic bacteria. For people with severe gut issues, even a small amount of xylitol left on the teeth and gums could cause a reaction. If you use a toothpaste that contains xylitol, make sure to rinse your mouth thoroughly with water.

Thank you for posting the information about bone broths! I have been trying to heal my gut, and I was wondering why my homemade soups, made with my homemade bone broth, were causing me to bloat and get gassy… This makes me sad, but in the best way, as I now know what I am dealing with.
xylitol has been shown to inhibit several opportunistic bacteria, fungi / yeast and even viruses. it has of course a prebiotic effect as well. But this can just be confused with xylitol ability to also kill several of this pathogens causing a herx reaction.
