Many of us try a vegan keto diet in an effort to improve our digestion and health. After all, sugar, meat, gluten, dairy and eggs are all pro-inflammatory foods, and so a diet that aims to reduce or even eliminate those factors must be able to drastically improve digestion, right? Well, yeah, sometimes… But then, sometimes you’ve been eating a low-inflammatory diet, and yet you’ve somehow still got those pesky IBS symptoms that flare up every so often. So, what’s the next step?
Well, for me, I decided to eliminate FODMAPS for a little bit. I was motivated to try this after months of dealing with cramps and bloating and, uh, other digestive issues every time I ate garlic or onions. It’s kind of crazy that I waited so long, but when you already eat a low carb, gluten free, vegan diet with minimal nuts, you really can be reluctant to remove anything else… If you’re curious about what I eat in a day on a low carb vegan low-FODMAP diet, check out this post!
But, enough about me. This is about vegan keto diets and FODMAPs.

What is a FODMAP?
Let’s start off by addressing the most basic question here: what is a FODMAP?
Basically, FODMAP is an acronym for a group of sugars: Fermentable Oligosaccharides, Disaccharides, Monosaccharides And Polyols. These sugars are found in fruits, vegetables, grains, nuts, sweeteners and sugar alcohols, dairy products and legumes.
These sugars can exacerbate IBS in two ways. Firstly, as they are readily digestible by our gut bacteria (hence, “fermentable”), these sugars can cause quite a bit of gas and bloating in some people. Secondly, these FODMAPs tend to draw water into the bowels, leading to loose stools and/or diarrhea. If you’re thinking that this doesn’t sound particularly fun, you are correct.
So, you can see why some people are keen to remove these sugars from their diet.
What Foods Are High in FODMAPs?

So, What Vegan Keto Foods Are Low in FODMAPs?
Now the good news for those of you who are already on a low carb or keto vegan diet, is that you’re likely avoiding many foods that are high in FODMAPs just by eating low carb and avoiding dairy. So, compared to Standard Western Diet eaters who switch to a low-FODMAP diet, you won’t have quite the hurdle to leap over.
The following lists of foods are not only low in FODMAPs, they are also low carb in general, and suitable for a vegan keto diet. These are all whole foods, so if you’re questioning a product from the grocery store, you may want to consult a more complete list.
