Sunflower Seeds

Low FODMAP

Serving sizes

Sunflower Seeds changes rating with portion size. These are the amounts tested in the literature behind our ratings.

  • About 1 tablespoon (15g) Low
  • Larger portions Moderate
  • Much larger portions High

Sunflower seeds are Low FODMAP at about 1 tablespoon (15g), with the level climbing at bigger handfuls.

  • At about 1 tablespoon (15g) sunflower seeds are low.
  • Fructans and GOS build at larger portions, which are moderate, and much larger portions are high.

Sprinkle them over salads or yogurt for crunch, and watch handful size if you snack straight from the bag.

Why sunflower seeds is rated low

Sunflower seeds are mostly fat and protein, and they are low at about 1 tablespoon (15g). At larger portions they move to moderate and at much larger portions they are high, as fructans and GOS build with a bigger helping. That climb matters more here than it does for most foods, because sunflower seeds are a snack that is eaten absent mindedly. Sprinkled over a salad or a bowl of porridge they stay comfortably low. Eaten steadily out of an open bag while doing something else, the total drifts upward without any decision being made, and a second handful is all it takes.

What changes your risk

  • Serving size This is the whole story. About 1 tablespoon (15g) is low, larger portions are moderate and much larger portions are high, and raw, roasted or salted makes no difference to that climb.
  • Eating from the bag Snacking straight from the packet is how a tablespoon sprinkle quietly turns into a much larger handful. Tip them into a bowl or over food instead.
  • Seasoned and flavoured packets Barbecue, ranch and other savoury coatings usually list onion powder and garlic powder, which are high FODMAP ingredients the plain seed does not have. Plain, salted or dry roasted keeps things simple.
  • Trail mixes and seed bars Dried fruit concentrates everything left after the water goes, so raisins, dried apple and dried mango in the mix carry far more FODMAP load than the same fruit fresh, and cashews and pistachios often turn up alongside. The seeds in a mix count toward their own serve too.
  • Ground into a butter A spread made from ground sunflower seeds is far easier to eat in quantity than a sprinkle of whole seeds, so weigh a spoonful rather than assuming a thin spread stays under about 1 tablespoon (15g).

What else works

Sunflower seeds do not need replacing at about 1 tablespoon (15g), so the useful list is what else can go in the bowl. Pumpkin seeds, walnuts, macadamias, pecans and plain peanuts are all low at their own serves, and rotating between them across a day spreads the load better than leaning on one. For crunch on a salad without any seed at all, toasted gluten free breadcrumbs, sliced cucumber or carrot batons do the job. The lookalikes to leave out of the mix are cashews and pistachios, which are not low FODMAP at ordinary servings, and dried fruit, which is far more concentrated than it looks sitting next to the seeds.

How to keep it low

Buy plain, raw or dry roasted seeds rather than the flavour coated packets, and check the ingredient list on anything described as seasoned for onion and garlic powder. Store them in an airtight container somewhere cool, since the fat in them goes rancid faster than most pantry items and a bitter seed is a stale one. Portion them out before you start: measure about 1 tablespoon (15g) once to see what it looks like, tip that into a bowl or straight onto the salad, porridge or lactose free yoghurt, and put the bag away rather than keeping it open on the desk. Toasting them briefly in a dry pan brings out much more flavour, which makes a smaller sprinkle taste like more.

Common questions

are sunflower seeds low fodmap

Yes, at about 1 tablespoon (15g). Larger portions are moderate and much larger portions are high, as fructans and GOS build.

how many sunflower seeds can i eat

About 1 tablespoon (15g) is the low serve, roughly a sprinkle over food. Larger portions step up to moderate, so measure it once rather than snacking steadily from the bag.

are roasted sunflower seeds ok

Roasting does not change the FODMAP content, so plain roasted seeds behave the same as raw ones at about 1 tablespoon (15g). The catch is flavoured coatings, since barbecue and ranch style packets usually contain onion and garlic powder.

can i eat sunflower seeds on the elimination phase

Yes, keeping to about 1 tablespoon (15g). Buy them plain rather than seasoned, and watch trail mixes, where dried fruit, cashews and pistachios are usually the bigger issue.

Where this rating comes from

Sunflower Seeds is rated from published lab measurements of its FODMAP content, using the low, moderate and high cutoffs of Varney et al. (2017).
