Have you ever felt like even the healthiest foods don’t agree with your gut? Or are you on a ketogenic diet and still feeling bloated or dealing with digestive issues? Enter FODMAP. These specific types of carbohydrates ferment in the intestines and can cause indigestion, especially in people with irritable bowel syndrome or sensitive stomachs. But here’s the twist. Keto and low FODMAP diets overlap more than you might think.
Let’s break down the basics, discuss FODMAPs regarding the ketogenic diet, and discuss how tension, discomfort, and digestive disruption can occur while maintaining ketosis.
What are FODMAPs?
Abbreviation for FODMAP Fermentable oligosaccharides, disaccharides, monosaccharides, polyol–It’s a mouthful, right? These are short-chain carbohydrates found in many foods that are difficult to absorb properly in the intestines and can cause symptoms such as gas, bloating, diarrhea, and abdominal pain.
Decomposition of FODMAPs
oligosaccharide – Found in wheat, onions, garlic, and legumes.
disaccharide – The most common is lactose. teeth Found With dairy products.
monosaccharides – Fructose is found in high amounts in fruits such as apples, honey, and mangoes.
polyol – Sugar alcohols such as sorbitol and mannitol teeth often found Found in “sugar-free” products and some fruits and vegetables.
These FODMAP foods ferment rapidly in the gastrointestinal tract, which can be harsh on people with sensitive guts. This is why some people require a low FODMAP diet to manage their symptoms.
What are FODMAPs on Keto?
The keto diet is high in fat and low in carbohydrates. Naturally reduces some FODMAPs, especially carbohydrates. But even on a keto diet, you can still come across high FODMAP foods, which can affect your digestion and keep you from feeling your best. Achieving low FODMAPs on a keto diet isn’t as difficult as you might think, since the keto diet already restricts a lot of carbohydrates, but it does take a little strategy.
Why is the keto diet low FODMAP?
People with IBS and other digestive issues often find the keto diet helpful because it cuts down on carbohydrate-rich foods that can cause bloating and discomfort. But keto doesn’t automatically eliminate all FODMAPs. So if you’re experiencing stomach issues even on a keto diet, it may be worth taking a low-FODMAP approach to avoid common high-FODMAP foods that may be sneaking into your diet.
Benefits of low FODMAP on a ketogenic diet:
Reduces bloating and gas – Less fermentation means more comfort for your intestines.
improved digestion – Easily digestible foods reduce inflammation and discomfort.
more energy – Many people feel lighter and more energetic when the bloating goes away.
High FODMAP Foods to Avoid During the Keto Diet
Even keto foods can contain high FODMAP ingredients. Below is a quick list of common high FODMAP foods that can interfere with a keto diet.
Avocado (large amount) – Avocados are suitable for keto, but the more you consume them (1/8 or more), the more polyols they contain.
cauliflower – Popular keto alternative, but high in FODMAPs.
onion and garlic – Keto friendly but rich in oligosaccharides.
Dairy products (lactose) – Heavy cream, milk, and soft cheeses can cause problems.
mushroom – High in mannitol, a polyol that contributes to FODMAPs.
some kind of nuts – Cashews and pistachios are high FODMAPs, so stick to macadamia or pecans.
