Gassy Vegans Rejoice?

Okay, so, vegans aren't the only ones who suffer from gas

Okay, so, vegans aren’t the only ones who suffer from gas

As some vegans (and those that have to share their surroundings) may attest, heavy flatulence is a consequence of the vegan diet. In other words, vegans fart a lot and there are some who attribute this directly to soy intake.

Leave it up to science to step in:

Scientists in Singapore may have found a way to reduce certain carbohydrates in soybeans that have long been blamed for flatulence…

In an article in the Journal of Agricultural and Food Chemistry, researchers in Singapore said they found a way round this by mixing soybeans with the fungus, R. oligosporus, which contains enzymes that appear to be able to degrade the two culprit sugars.

Are you a vegan who suffers from (or hell, revels in) heavy flatulence? What are your thoughts? Weigh in below.

    Hmmm. Yes. These things do happen. Alot. It’s okay. I’m glad to know my food is moving through me and being used by my body. Some meat eaters only poop once every 5 days. (This is per a long conversation I had the misfortune to overhear recently between multiple omnis about how they’re always constipated and don’t poop for days on end.) That is so nasty in every way. So bring on the farts, yo!!

    Never in over eight years of being a Vegan have I had a flatulence problem… even with all the beans I eat, but like most things, this isn’t exclusively a vegan problem – no matter how much the omni would argue about it.

    Protein powder was not created out of a Vegan need.
    Multi-Vitamins weren’t created out of a Vegan need.
    Beano wasn’t created out of a Vegan need ;)

    But they also say dairy causes flatulence! Science is so confusing.

    Personally, I’m no better or worse since I went vegan.

    Gee, and just this week I was practically living on stirfry, and have come to the conclusion that too much veggies (esp. broccoli) causes…well…an embarrassment of riches. (Seriously, the effect is way too much.)

    So do vegans pass gas excessively? Wouldn’t surprise me if we do…

    oh, I’m so glad I’m not the only one! However, I am soy-sensitive and consume very little soy, so that’s definitely not the culprit at my house. I have been thinking of doing a post on this, cause I want to know if vegans poop more, on average, than *healthy* omnis (not the ones who only eat meat, cheese, and white flour all day).

    note: I have found that a daily probiotic supplement helps immensely

    When I first went vegan I was slightly more gassy but that has changed, I am no more gassy then I was as an omni. I think my body is used to the amount of fibre and ruffage I eat so it no longer responds in a gassy way. I think when an omni has beans or too much fibre they get gassy because all their tummy flora and fauna are bombarded with more than it is used to processing where as if it were a regular part of their diet their digestive system would adapt. I am not a doctor but this is my theory as to why I (and the husband) am not any gassier given my high fibre vegan diet. BUT, the exception is broccoli and brussell sprouts, sulpher-y veges have a sulpher-y effect. Actually I may be even less gassy as I no longer consume dairy and bad fats which did make me gassy. Last point, I think the food moving through my system faster makes me less gassy too, seems constipated people are gassy as they wait for that stuff to get out. So the short of it, no I am not more gassy as a vegan I am less. Another way Veganism has made me even more perfect, ha! ;)

    @ vegeater

    Based on conversations (with various healthy-eating vegans and omnis) and on logic, I think that vegans poop significantly more. When you eat only plant foods, your only sources of protein also have fiber. Animal sources of protein have no fiber at all. More fiber = higher volume of poop and faster moving bowels = healthier colon.

    Maybe my innards are ironclad, but when I switched from SAD food to veggie way back in 19-aught-73, no digestive diff except for being more regular. From veggie to vegan and no undue emissions. Everything cranks along nicely, thank you.

    My omni friends comment far more about poots.

    Including a fair amount of cumin in your diet should
    reduce flatulence — Middle eastern and latin american
    diets which contain a lot of beans also tend to contain
    a lot of cumin –so someone must have recognized this long
    ago. Cumin is also a good anti-inflammatory and has done
    wonders for my carpel tunnel syndrome

    The initial switch from veg to vegan included about a month of embarrassment for me. It was bad.
    Now – it’s all good. It might be that my body is used to it – it may be the daily probiotic… I don’t know… but I’m glad THAT’S over!

    Thanks so much for making me laugh! I went veg about 3 months ago and my husband is complaining bitterly about my.. Exhaust. I’ll try probiotics and cumin. Thank you!

    Try eating Papaya, organic pickles, Miso soup, all are great sources of enzymes

    Flatulence is a totally normal bodily process. Though it might be annoying, it happens, and it’s good for you. Stay vegan! Poop more!

    What kinds of vegan probiotics are there? Are there pills? I am a picky eater when it comes to new foods, sadly to say. I am 15.

    I’m adding a comment here because I too was searching online about what to do regarding vegan gas; every time I tried to switch from a vegetarian to a vegan diet I had HORRIBLE gas, so indescribably bad that I switched back to animal products twice. I am so relieved to have tried taking a probiotic, and now the gas is GONE! Its a miracle. And I only took one per day (instead of 2 as indicated) and then not every day (pretty sporadic, yet apparently it was enough for my body to establish equilibrium). You can also try eating probiotic foods such as non-dairy yogurts with active cultures, sauerkraut, kimchi, tempeh, etc. Don’t give up on your vegan diet… try a probiotic (or a few different kinds, until you find one that works best for you). Be sure to get a probiotic that contains guaranteed live active cultures (should be refrigerated). Good luck!

    I wa going to borrow my mom’s book, Fit For Life. I remember her making me eat only fruit in the morning. I think being a vegan now (3 weeks) has made me more gassy but I’m also mixing fruit in between regular meals. I know fruit takes longer to digest, but no concrete time per fruit or veggie because everyone’s body is different. I love being vegan, I never want to eat meat, (except fish) I just think I can’t be this gassy, it’s very rancid. Eating dairy or meat I recall the farts smelling like cows, and I thought this is gross. Didn’t expect this to be so strong when cutting out animal products. Before vegan I was cutting meat out and noticed I no longer had smelly farts, so that made me think about switching completely. I will try probiotics now that dairy is out of my diet. But has anyone noticed when they are more gassy? mixing their fruit with vegan food? Italians usually have salad, fruit after a meal, and when I was in Italy I never had a problem with so much gas.

    Okay, this is a seriously old thread, but I think I’ll post a comment anyway for all those gassy vegans out there. :) When I first went vegan, the gas was intense and constant. My husband learned to accept it and even laughed about it because there was no way I could hide it! It took about six or seven months to adjust, until one day I realized I hadn’t been gassy in a very long time. I don’t know if my digestive enzymes changed, or what, but it was a nice surprise! So, have faith if you’re a new vegan. Someday soon your gassy cloud will lift and the air will once again smell sweet around you. :)

    I dont know I’ve been mostly vegan for years now and I take vitamins and probiotics and I rarely eat soy. I only buy soy-free earth balance and veganaise – I just wish the flatulance was less frequent!
