As an IBS dietitian I am always reading up on the latest IBS research. On Instagram @AndreaHardyRD, I talk all about fat and how it impacts the gut. Keep reading to learn more!

Fat isn’t a FODMAP but it CAN influence digestion. 😮⁠

⁠In fact, depending on your diet, you may be better off starting with a reduction in fat and other simple dietary strategies rather than jumping RIGHT to FODMAPs to manage your IBS! 💁‍♀️⁠

How does fat impact digestive symptoms?⁠

1️⃣ Fat takes longer to digest, which slows digestion. In those with constipation, this can cause more digestive distress.⁠

2️⃣ Fat limits our guts ability to clear gas. With the slowing of digestion, gas stays longer in the gut, building up and causing more digestive discomfort. In IBS patients, this effect is actually exacerbated, meaning you have an even tougher time clearing gas! ⁠

3️⃣ Many times, bile acid malabsorption is the underlying cause of diarrhea. High fat intakes trigger the release of bile into the gut. Bile helps with the digestion and uptake of fat in the intestines, but some individuals have a limited capacity to reabsorb that bile, leading to diarrhea and bloating. ⁠

I’m seeing more and more people trend toward a higher fat diet in favour of reducing carbohydrates (not my favourite dietary trend!), often triggering digestive symptoms. Many times, simply reducing intake of some of their higher fat foods can significantly reduce symptoms, without any majorly restrictive diets! ⁠
