I do get a lot of questions about IBS and peanut butter and whether there is a specific low FODMAP peanut butter that you need to look for.

This is why I’ve taken the opportunity below to answer some common questions about the key ingredients in this post – it can be so confusing knowing what to buy!

Is Peanut Butter Low FODMAP?

Yes, peanut butter is a low FODMAP ingredient! At ‘typical’ portions of 2 tablespoons, peanut butter gets the green light for the low FODMAP diet. However, if you read the Monash notes, it takes just under 6 tablespoons to hit the moderate cut offs, so you can definitely go above a ‘typical’ portion!

Many people assume that only natural peanut butter is IBS-friendly, but you can also eat the popular favourites like Kraft Original Smooth or Skippy. Although there is sugar added, it is not high FODMAP.

Be sure to avoid peanut butter varieties that have honey added, as honey is high in fructose, a type of FODMAP.

Is Almond Milk Low FODMAP?

There are so many milk alternatives these days. Almond milk is a popular one and is often easy to find at grocery stores, coffee shops, even smaller convenience stores. Almond milk is low FODMAP at portions up to 1 cup, so you can definitely use it in a lot of different ways. Try it in cereal/oats, lattes, or low FODMAP baking.

Is Oatmeal Low FODMAP?

While there are some grains that are very high FODMAP (barley, wheat, and rye for instance), oatmeal is not. However, oatmeal isn’t something we can eat endless amounts of on a low FODMAP diet. It can become high FODMAP in larger amounts – the research suggests keeping portions at 1/2 cup oats per sitting. To be clear, this measurement references the oats measured dry – they will expand after they’ve been cooked or soaked overnight. Therefore, the recommended low FODMAP portion is still quite liberal!

Are Chia Seeds Low FODMAP?

Yes, chia seeds are low FODMAP up to a 2 tablespoon portion. This recipe only calls for 2 tablespoons split between 4 portions, which means we definitely don’t exceed the low FODMAP portion. We love adding chia seeds as a fibre booster on a low FODMAP diet, like in this fibre-boosting low FODMAP drink. Keep in mind, some people with IBS find they need to take it slow when adding fibre – especially if they’re not used to having all that much.

Love this low FODMAP recipe as much as we do? Our collection of low FODMAP recipes were created to help you navigate the low FODMAP diet. Many of our patients have tried implementing the low FODMAP diet on their own. However, this diet should be conducted with the support of a registered dietitian. At Ignite Nutrition we offer one-on-one nutrition counselling to help you start on the low FODMAP diet with guidance.
