Does Quinoa Cause Gas? And How to Stop It If It Does.

If you’re starting a healthy eating regime, you might have swapped some of your normal side dishes like rice or pasta for quinoa – but, if doing so has also led to an increase in feelings of bloating or gas you might be wondering if your new healthy addition is behind this – and if quinoa causes gas. So let us explain.

Why Can Quinoa Cause Gas?

Well, let’s start with the fact that it’s a seed (although usually referred to as a grain) – and seeds contain fibre and, pretty much any food that contains fibre can cause gas.

It’s a natural process that occurs when bacteria in the gut digest fibre in the food – but, it’s true that some fibre-containing foods can cause more gas than others, or contain other ingredients that increase gas levels – and one of these, saponins, is another reason why quinoa might make you gassy…

The Saponin Story

Saponins are bitter tasting compounds found in the exterior coating of quinoa. It’s thought that they are there as a way to protect the seeds from insect damage as they taste horrible to anything biting into the plant.

For this reason, most of the saponins in quinoa sold in supermarkets are now removed as part of the manufacturing process – it can taste quite bitter otherwise – but, some do get left behind.

Most people have no issue ingesting these (in fact, there might be some health benefits to saponins) but if you’re one of the people with a sensitivity to them, you might find that these can cause gas, bloating and/or stomach pain.

There’s no clear test to tell if saponins are behind your post-quinoa gas, but, if you also get bloating from chickpeas or soy beans, that might be a sign as they contain higher levels of saponins than quinoa does.

Other foods in the quinoa family can also contain saponins and may lead to gas if you eat lots of them. These include spinach, Swiss Chard, Rainbow chard and rhubarb – that might sound strange as they are all veggies, but remember, quinoa isn’t a grain, it’s actually a seed and a member of the grass family.

Admittedly, when you see it growing, the link between it and chard and rhubarb is a bit clearer – look.

How to Stop Quinoa Causing Gas

Quinoa is generally a very healthy food – it’s one of the few grains that also contains high levels of protein, it has all nine amino acids and includes nutrients including iron, vitamin E and magnesium – therefore, if you can keep it in your diet, you should – especially if you’re vegetarian or vegan.

The good news is, you don’t need to avoid eating quinoa to stop quinoa-bloat – there’s a really simple way to reduce any saponins left on the seeds.

Rinse the quinoa before you cook it.

This helps remove leftover saponins that might be causing problems.

All you need to do is get a sieve with very small holes, pop your portion of (uncooked) quinoa into it and run it under the tap for up to 2 minutes. That should get rid of most of the excess saponins and eliminate the problem.

What if Rinsing Doesn’t Work?

If it doesn’t, it’s possible that saponins are not your issue. It might simply be that you’ve increased fibre levels in your diet too quickly.

When you do this, it’s the gut bug equivalent of letting a kid loose in a candy shop, they eat everything, get overexcited and you can get bloated. Build things up slowly.

Or, you might be blaming quinoa, but the culprit could be something else in your diet. Especially if you’ve started googling and seen posts about saponins, you might be blaming the quinoa not realising that you always have eggplant with quinoa (and they’re another food that can trigger gas).

The only way to tell what’s really causing problems is to keep a food/symptom diary and make sure you’re not blaming the wrong food.

Is Quinoa a High Fodmap Food?

One of the reasons why many of the foods we talk about in our posts on bloating lead to excessive gas is that they contain higher levels of sugars called FODMAPs which can cause more gas than other ingredients as they’re broken down.

Chickpeas are one example of this we’ve already talked about, mushrooms are another.

However, in a normal sized serving of around 100g, quinoa is classed as a low FODMAP food which means it’s unlikely that a reaction to FODMAPs is the cause of any gas produced.

On their FODMAP tracking app, the team at Monash, who are the gurus of all things FODMAP say that FODMAPs in quinoa may cause problems at about 575g of cooked quinoa – but that’s a very large serving, around four times more than most people will be consuming in one go.

Does Quinoa Contain Gluten?

No – quinoa is gluten free, so a reaction to gluten is not on the list of reasons why quinoa may cause gas.

How Long Does Gas from Quinoa Last?

The good news is that any kind of bloating or discomfort caused by gas will pass within a few hours as the gas naturally works its way out of your system.

If you’re very uncomfortable, then you might be able to help things move faster by drinking peppermint tea. Peppermint helps relax the gut which releases gas.

Or, get into a position where your buttocks are raised – ie child pose from yoga, or simply kneeling down and poking your bum in the air – which again, can encourage the movement of gas.

You’ll also find some other suggestions on ways to release gas in this piece.

Remember though most of the time bloating and gas are totally normal and pass quickly, but we do have to just mention that if you’re getting a lot of discomfort with your bloating, if you have any other symptoms like loss of appetite or weight loss and if your bloating doesn’t come and go, it’s best to just go and see your GP to check there’s not a problem like IBS or something else going on.

So there you have it. The main reasons why quinoa might make you gassy and, a few solutions that will hopefully stop it happening to you.
