Pretzels

Low FODMAP

Serving sizes

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

  • ½ cup (21g) Low
  • ⅞ cup (36g) High

Pretzels stay Low FODMAP at a small serving, thanks to their modest FODMAP load at ½ cup (21g).

  • Pretzels are typically made from wheat, but at ½ cup (21g) the overall FODMAP load stays comfortably low with no single subgroup elevated.
  • As the handful grows, that overall FODMAP level climbs into the high range, so the portion size is really what tips the balance here.

Keep to a ½ cup (21g) serving to enjoy that satisfying crunch while staying comfortable.

Why pretzels is rated low

Pretzels are low at ½ cup (21g), and the data records no single raised subgroup for them, so what you are managing is the total FODMAP load rather than one particular trigger. The climb is short and worth knowing: by ⅞ cup (36g) the same pretzels test high. No moderate step is recorded between those two rungs, which means the amount you put in the bowl is doing almost all of the work on this page. That is a real cliff rather than a gentle slope, and it is the reason pretzels are easy to enjoy from a portioned serving and hard to enjoy from an open bag.

What changes your risk

  • Serving size, and the short climb ½ cup (21g) tests low and ⅞ cup (36g) tests high. There is no cushion between those two figures, so the serving is the whole story with this snack.
  • Eating straight from the bag Pretzels are small, crunchy and easy to keep reaching for, which is exactly how a low serving turns into a high one without anyone noticing. Portion into a bowl or a container first and close the bag.
  • Flavoured and filled versions Honey mustard pretzels bring honey, onion and garlic seasoned coatings bring their own high FODMAP ingredients, and filled pretzels count the shell plus whatever is inside toward the same serving. The plainest salted pretzel is the one this data describes.
  • Soft pretzels are a different food A bakery soft pretzel is bread rather than a crunchy snack, and it is not covered by this serving data at all. The same goes for pretzel buns and pretzel rolls.
  • Stacking through the meal A low serving is per serving, not per meal. Pretzels sitting alongside several other low servings in one sitting push the total FODMAP load of that meal up, so spreading snacks across the day is easier on the total than clustering them.

What else works

If pretzels are filling a salty and crunchy gap, plain salted potato chips and plain rice cakes both sit in the low column at their own tested servings, and peanuts, walnuts, macadamias, pecans and pumpkin seeds give you something to crunch through, each at its own tested serving rather than without limit. What does not work as a substitute is ordinary wheat crackers or bread at ordinary servings, pretzel buns and soft pretzels, or honey mustard and onion seasoned pretzel varieties. Skip the dips that usually arrive with them too, since hummus is a chickpea product and onion based dips are exactly what they sound like. Plain mustard, or a hard cheese such as cheddar on the side, does the job better.

How to keep it low

Portion before you snack rather than during. Measure out ½ cup (21g) into a bowl or a small container, then put the bag away, because pretzels are the classic food eaten past the serving while talking to someone. Check the ingredient list for honey, onion powder and garlic powder, which show up more often in flavoured and coated varieties than people expect. At a bar or a party the bowl on the counter is effectively bottomless, so take your serving onto a plate or a napkin and stand somewhere else. Keep opened bags sealed, since soft stale pretzels get eaten out of habit rather than enjoyment.

Common questions

how many pretzels can i eat on a low fodmap diet

½ cup (21g) tests low. By ⅞ cup (36g) pretzels test high, with no moderate step recorded in between, so the serving really matters here.

are pretzels high fodmap

It depends entirely on the amount. They are low at ½ cup (21g) and high at ⅞ cup (36g).

can i eat pretzels on the elimination phase

Yes, at ½ cup (21g) of plain salted pretzels. Keep to that serving and check the ingredient list, since honey mustard and onion seasoned varieties bring high FODMAP ingredients of their own.

are soft pretzels low fodmap

This serving data covers hard crunchy pretzels only. A bakery soft pretzel, a pretzel bun and a pretzel roll are bread rather than a snack food, and none of them are covered by the ½ cup (21g) figure.
