Mushrooms contain raffinose, a complex sugar, which passes through the small intestines into the large intestines where bacteria breaks down.
This then produces methane gas, carbon dioxide, and methane gas which leaves through the rectum.
If you have prior digestion problems or IBS, mushrooms can cause digestive distress.
The cell walls contain chitin, which can be difficult for the body to digest.
Mushrooms contain a lot of proteins that can be difficult for the stomach to digest.
There are some basic guidelines to follow when preparing mushrooms so that they aren’t difficult to digest.
Cooking is one of the best ways to enjoy mushrooms without causing digestive issues.
Steaming mushrooms helps break down the indigestible elements and is one of the best ways because it protects heat-sensitive nutrients such as vitamin C.
Other methods include sauteing, frying, and baking the mushrooms.
Some larger varieties can be grilled as they’re fairly meaty in texture.
As long as mushrooms are cooked well, they will be fairly easy to digest.
Many recommended cooking mushrooms in their own sauce and avoiding difficult-to-digest sauces such as sauces that contain cream.
Sauces that contain herbs that aid digestion also helps make them easier to digest.
Many people recommend avoiding cooking mushrooms with alcohol, this is because the protein in the mushrooms is trapped by the alcohol.
This then becomes more resistant to the digestive process and makes it harder to break down, potentially causing digestive distress.
Undigested mushrooms in stool
Mushroom cell walls contain chitin, which is fairly hard for the body to digest.
Cooking mushrooms is one way you can help break down chitin, however, you might find that there are still undigested mushrooms in your stool.
This is perfectly normal because of how durable chitin is, it needs to be broken down well in order to digest fully.
One way you can ensure that the mushroom is digested well is by chewing your food well.
You may have a habit of eating quickly or not chewing a lot, if this is the case, the mushrooms you consume may not digest fully, in fact, they may come out almost whole.
Avoid eating raw mushrooms and ensure they’re finely chopped if you want to avoid pooping out whole mushroom slices.
Humans don’t actually have the ability to digest chitin so we need to do some groundwork if we want to enjoy mushrooms fully.
Ensure you’re eating cooked mushrooms, cooking mushrooms all the way through will prevent undigested mushrooms from leaving your body as this breaks down the chitin.
Chewing your food very well will also help a lot, especially as most of us have a habit of not chewing enough as it is, so be mindful of this.
How long does it take for mushrooms to digest?
It takes around 4-6 hours for mushrooms to digest.
Digestion time depends on a few factors.
Many people notice that they will often poop out whole or undigested mushrooms.
This is mostly due to the chitin contained within the mushroom cell walls, this chitin is a complex sugar that the body finds hard to digest.

In order to ensure mushrooms are digested well, it’s best to cook mushrooms as this helps break down the chitin making it easier for your body to digest.
As well as this, you should also ensure that you’re chewing the mushrooms well.
Many people have a habit of eating quickly or swallowing food without chewing well, with mushrooms this can mean your body is unable to digest properly.
You should also consider chopping up the mushrooms into smaller pieces, this helps them digest better.
Mushrooms are FODMAP food and some varieties include the popular button mushrooms, portobello, and shiitake containing high-FODMAP.
Oyster and canned mushrooms contain low-FODMAP so are a good substitute especially if you suffer from IBS or have digestive issues.
If you have these issues, mushrooms can take much longer or quicker to digest depending on your health.
Mushrooms also contain mannitol, which pulls water into your large intestine leading to loose stools.
This causes diarrhea and could mean you digest the mushrooms much quicker.
Shiitake mushrooms have high mannitol levels whereas oyster mushrooms have a lot less.

Mushrooms are a FODMAP food, FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides and polyols.
FODMAP foods are easily fermented by bacteria found in the large intestine.
When mushrooms are fermented in the gut, they can lead to bloating, gas, and stomach pain.

A side effect of mannitol is that it can cause diarrhea as the mannitol can pull water into your large intestine and lead to loose stools.
This might mean that you poop much quicker than expected.
