Red Pepper

Low FODMAP

Serving sizes

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

  • About ½ cup (45g) Low
  • Larger portions Moderate
  • Much larger portions High

Red pepper is Low FODMAP at about ½ cup (45g), with Excess Fructose building at larger portions.

  • About ½ cup (45g) of red pepper is low.
  • Excess Fructose builds with the amount, so larger portions are moderate and much larger portions are high.

Enjoy it raw, roasted or sautéed in salads and stir-fries, keeping to about ½ cup (45g) per serve.

Why red pepper is rated low

Red pepper is low at about ½ cup (45g), a modest handful of strips. Larger portions move it to moderate and much larger portions to high, as the excess fructose builds with a bigger serve. Nothing changes about the pepper across those serves. It is the amount, in one sitting, that adds up. Roasted peppers in particular pack down enough that reaching a large serving is easier than it sounds, so red pepper works best as one vegetable among several on the plate rather than the whole of it.

What changes your risk

  • Serving size About ½ cup (45g) is low, larger portions are moderate and much larger portions are high. A whole stuffed pepper or a big pile of strips goes well past the low serve.
  • Roasting and chargrilling Heat does not destroy FODMAPs, so roasting does not lower what is in the pepper. It does drive off water, so a cup of roasted strips started out as considerably more raw pepper than a cup of raw ones. Portion it raw if you want the serving to match.
  • Jarred and marinated peppers These are the ones to check. Antipasto peppers, roasted pepper jars and marinated strips are frequently packed with garlic, and pepper pastes and dips are usually built on onion and garlic. Draining the jar does not remove flavourings that have soaked in, so read the ingredient list.
  • What it is cooked with Red pepper rarely arrives alone. Stir fries, fajitas, sauces and sofrito style bases nearly always start with onion and garlic, which is where much of the load in a pepper dish comes from. Garlic infused oil carries that flavour without the troublesome part of the garlic.
  • Dried and powdered forms Drying removes water and concentrates everything left behind, so dried peppers and pepper powders are not the same food as fresh, and spice blends built on them commonly include onion and garlic powder too.

What else works

Because the low serve is modest, variety on the plate is the useful move. Cucumber, carrot, zucchini, green beans and bok choy all work in the same salads and stir fries, so a mix of those with a little red pepper gives you volume and colour without leaning on one vegetable. The forms to treat separately are the processed ones: shop bought roasted pepper dips, antipasto jars and pepper pastes are usually made with garlic and onion, and a chilli or paprika seasoning blend is usually more than just ground pepper. If you want the sweet roasted flavour, roasting your own and storing them in plain oil gets you there without the marinade.

How to keep it low

Look for peppers that feel heavy and firm with taut, glossy skin, and store them whole in the fridge rather than cut, since cut peppers soften quickly. Slice and portion about ½ cup (45g) before anything goes in the pan, especially if you plan to roast, because the volume falls sharply once they cook down. It works raw in salads, roasted, or sauteed into stir fries. When you are cooking a stir fry or a traybake, start the pan with garlic infused oil, bulk it out with other vegetables, and finish with the green tops of spring onions or chives. Eating out, fajitas, stir fries and pepper sauces are usually built on an onion and garlic base and tend to carry generous amounts of pepper, so ask what is in the sauce and how much pepper the dish carries.

Common questions

how much red pepper is low fodmap

About ½ cup (45g) is low. It is moderate at larger portions and high at much larger portions, so keep it to a modest handful.

can you eat too much red pepper on a low fodmap diet

Yes. Larger portions are moderate and much larger portions are high, so a big helping in one sitting adds up quickly. Keep to about ½ cup (45g) and fill the rest of the plate with other vegetables.

are roasted red peppers from a jar low fodmap

The pepper itself follows the same serves, since cooking does not change the FODMAP content, and roasted strips pack down so a spoonful holds more pepper than it looks. The jar is the other problem: marinated and antipasto peppers are commonly packed with garlic, and draining them does not undo that.

is red pepper ok during the elimination phase

Yes, at about ½ cup (45g). Portion it rather than adding by eye, since a bigger helping moves it out of the low range.

Where this rating comes from

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