2021 Low, Moderate, and High FODMAP Vegetable Guide


Long before you started a low FODMAP diet, you were likely told, “Eat your vegetables, they’re good for you”, over and over again. In this article, let’s take a slightly new approach to this old adage and make it, “Eat your vegetables, they’re good for you… AND your gut bacteria.”

Does knowing that you are also feeding trillions of little friends in your belly (your gut microbiota) make vegetables a more intriguing option? Our gut bacteria loves the fiber that is found in many wholesome foods, especially vegetables. This fiber has been recently redefined as microbiota-accessible carbohydrates or MACs (not to be confused with a Big Mac). Vegetables are rich in MACs, which represents a major energy source for our colonic bacteria. Let’s learn more about how you can incorporate more vegetables — and MACs — into the low FODMAP diet.

First things first: How much should we aim for?  

I recommend aiming to fill half your plate with vegetables for lunch and dinner. This is about 2 cups worth. I use the word “aim”, because it is important to have something to work towards. Some days may be closer than others and that’s okay. I also recommend eating vegetables for snacks too. Keep reading for some useful tips on how to enjoy more vegetables throughout the day. 

FODMAP Free and Low FODMAP Vegetables

As you can see below, there is a huge variety of low FODMAP vegetables to enjoy! The vegetables that are “free” can be eaten in any quantity and will never become high in FODMAPs no matter how much you eat. You can find these foods in the Monash app, with the following note:

FODMAPs were not detected in this food. Eat freely and according to appetite.

High FODMAP Vegetables

These are the high FODMAP vegetables that you should avoid during the elimination stage.  Although you may see some of your favorite vegetables here, the list is significantly smaller than the list of lows and moderates.  Keep in mind that you can test your tolerance for these vegetables in the reintroduction phase, and will likely be able to add some of them back in the long run.

  • Asparagus
  • Artichokes, pickled in oil
  • Cauliflower
  • Garlic
  • Mushroom, button, enoki, porcini, portobello, shiitake
  • Onion, shallot, Spanish, spring, white
  • Onions, pickled small
  • Peas, frozen

Tips for Eating More Vegetables

If you’re like most, you may find it difficult to fill half your plate with veggies right away. Here are a few tips I give my clients to lessen the burden when they first start out:

  1. Buy pre-washed and trimmed low FODMAP vegetables like baby carrots, green beans, and broccoli heads.
  2. Buy pre-washed bags of salad, coleslaw, and spinach (hint: you can freeze the spinach if you aren’t going to eat it in time). 
  3. Prepare a container of mixed vegetables once a week such as cherry tomatoes, baby carrots, cucumbers, red peppers, and broccoli.
  4. Serve a variety of colored vegetables to make them look more appealing. Believe me, this actually works!
  5. Munch on vegetables as your appetizer because food tastes way better at the beginning of a meal when you are hungry then at the end when you are full.

Quick and Easy Low FODMAP Vegetable Recipes

I’m a simple gal when it comes to vegetables. Most of our dinner meals have either steamed vegetables (with a pat of butter), a green salad, and/or cut veggies. I’ll sign off with some simple recipes from my favorite low FODMAP experts and wish you the best of luck adding more vegetables (and MACs) to your dinner table!
