Low FODMAP nuts and seeds

I use nuts and seeds a lot in my dishes, whether that be as a garnish, in a salad or as the flour component of a cake. As such, I thought it would be handy to dive into the topic of low FODMAP nuts and seeds.

Low FODMAP nuts and seeds

Below is an alphabetically organised list of nuts and seeds and their low FODMAP thresholds. This information is the most up to date information available from Monash at the time of writing. As and when Monash update thresholds of different nuts and seeds, I will update the post.

I have also included some of my favourite low FODMAP recipes that incorporate nuts and seeds. Hopefully they will inspire you to include some in your own low FODMAP cooking.

Things to keep in mind when choosing low FODMAP nuts and seeds

Monash is an Australian institution. Although they don’t specify, I assume they use Australian cups and measures, which are larger than cups in other countries. Using the gram measures is always the most accurate.

Everyone is different and has different intolerances. If you know that a certain nut works well for you, there is absolutely no need to avoid it after the elimination phase. In fact, the whole idea is to reintroduce as many foods as possible.

This list, nor any of my recipes, are a substitute for medical advice. I am not a doctor or a dietician. I am a person who develops these recipes as I struggle with digestive issues myself. I know how hard it can be to find low FODMAP vegetarian recipes that are fun, which is why I do what I do.

What are galacto-oligosaccharides or GOS?

Many of the nuts in this list have a threshold at which they become moderate for galacto-oligosaccharides (or GOS) so it’s worth quickly discussing what this is.

Galacto-oligosaccharides are part of the oligo group of FODMAP, AKA the O in FODMAP. They are in this fun club with fructans, the other oligo. I won’t get into too much science (I am not a dietician or a doctor) but I will link this Monash article if you’d like to read more about their scientific makeup.

GOS are similar to, but separate from, fructans. Both of these groups contain sugars that humans cannot absorb, as we don’t produce an enzyme capable of breaking them down. In people with normal digestion, GOS (and fructans) move through the digestive system without too much issue regardless. In people with sensitive digestive systems, however, they can cause digestive symptoms.

Foods that are high in galacto-oligosaccharides

The main group of foods high in GOS is legumes. According to Monash, other foods include cashews and pistachios, soy milk made from whole soy beans, hummus and oat milk.

Low FODMAP thresholds for nuts and seeds

Almonds

Almonds are considered low FODMAP in servings of 12g per person, or approximately 10 almonds per serve. In 24g servings or approximately 20 nuts, they become high in GOS.

Almond meal is low FODMAP in 33g serves, which is approximately 1/3 cup. In 48g servings or approximately 1/2 cup, it becomes high in GOS.

Brazil nuts

Brazil nuts are low FODMAP in 40g serves, or approximately 10 nuts. In serves of 52g or approximately 13 nuts, they become moderate for GOS.

Chestnuts

Boiled chestnuts are low FODMAP in 168g serves, or approximately 20 chestnuts. In serves or 295g or approximately 35 boiled chestnuts, they become moderate for fructans and GOS.

Roasted chestnuts are low FODMAP in 84g serves or approximately 10 chestnuts. In serves of 134g or approximately 16 chestnuts, they become moderate for fructans and GOS.

Chia seeds

Both black and white chia seeds are low FODMAP in 24g serves, which is approximately 2 tablespoons. 48g serves or approximately 4 tablespoons contains high amounts of fructans.

Flaxseeds

Flaxseeds are low FODMAP in 15g or serves or 1 tablespoon. In 30g serves or 2 tablespoons, they become high for GOS.

Hazelnuts

Hazelnuts are low FODMAP in 15g serves or approximately 10 nuts. They become moderate for GOS in serves of 20g or approximately 20 nuts.

Monash do not currently have an entry for hazelnut meal.

Hemp seeds

Hemp seeds are low FODMAP in 20g serves or approximately 2 tablespoons. In servings of 50g, they are moderate for GOS. This suggests there is a bit of wiggle room in what constitutes a low FODMAP serve.

Macadamias

Macadamias are low FODMAP in 40g serves or approximately 40 nuts. However, Monash states that only trace amounts of FODMAPs were found, and macadamias can ‘be eaten freely and according to appetite.’

Tiger nuts

Tiger nuts are not actually nuts, but tubers. Either way, they are low FODMAP in 20g serves. In 50g serves, they contain moderate amounts of fructans and GOS.

Pecans

Pecans are low FODMAP in 20g serves, or approximately 10 pecan halves. In servings of 100g or approximately 40 pecan halves, they contain moderate amounts of fructans and GOS.

Peanuts

Peanuts are low FODMAP in 28g serves or approximately 32 nuts. However, Monash says that they contain only trace amounts of FODMAPs, and can be eaten freely and according to appetite.

I have written an extensive post on the FODMAP content of peanut butter, which you can find here.

Pepitas/pumpkin seeds

Pumpkin seeds or pepitas are low FODMAP in 23g serves, or approximately 2 tablespoons. In 100g serves, they contain high amounts of fructans. This suggests that there is a little bit of wiggle room in what constitutes a low to moderate FODMAP serve.

Pine nuts

Pine nuts are low FODMAP in 14g serves or approximately 1 tablespoon. In serves of 100g or 8 tablespoons, they contain high amounts of fructans. This suggests there is a bit of wiggle room with a low to moderate serve.

Poppy seeds

Poppy seeds are low FODMAP in 24g or 2 tablespoon serves. Monash doesn’t specify a moderate or high threshold for poppy seeds.

Sesame seeds

Sesame seeds are low FODMAP in 11g serves or approximately 1 tablespoon per person. In serves of 66g or approximately 6 tablespoons, they contain high amounts of fructans. This suggests there is a bit of wiggle room in what constitutes a low-medium FODMAP serve.

Sunflower seeds

Sunflower seeds are low FODMAP in 6g serves or approximately 2 teaspoons. In serves of 70g they contain high amounts of fructans. This suggests that there is some wiggle room in what constitutes a low-moderate FODMAP serve.

Personally, I think it would be very helpful if Monash added a moderate threshold here. 2 teaspoons is a small serving and it feels like it muddies the water as to what constistutes a low FODMAP serve.

Walnuts

Walnuts are low FODMAP in 30g serves or approximately 10 nut halves. In 135g serves (approximately 35 nut halves) they contain moderate amounts of fructans. This suggests there is wiggle room in what constitutes a low FODMAP serve.

High FODMAP nuts

Cashews

Cashews are high FODMAP in 15g serves, with high amounts of GOS and moderate amounts of fructans.

Pistachios

Pistachios contain high amounts of GOS in 10g serves, and high amounts of both GOS and fructans in 23g serves.

Recipes that use low FODMAP nuts and seeds

Roast quinoa pumpkin salad

This roasted pumpkin, quinoa, kale and feta salad uses a smattering of chopped almonds for crunch and taste. It also uses a low FODMAP quantity of (optional) raisins for a delicious flavour contrast.
