Low FODMAP diet

By Kirsten Jackson

Low FODMAP fast food exists! It can be a quick and convenient food choice. This is not always the case if you have IBS, as common fast food ingredients may trigger your symptoms.

In this article, we will discuss how fast food can trigger IBS symptoms and how to prevent this.

We will also share low FODMAP meals in international fast food restaurant chains like McDonald’s.

Moreover, we will give you some delicious recipes you can prepare at home.

Can you eat fast food if you have IBS?

Although you might have had bad experiences with fast food and IBS in the past, the answer is yes, you can eat fast food.

In the following sections, we will explain how fast food triggers IBS symptoms and provide instructions on avoiding the flares.

Also, you can eat fast food as part of a balanced diet. Focus that most of your meals present diverse plant-based meals; when it comes to fast food, enjoy!

Why might fast food trigger your IBS symptoms?

There are two main reasons why fast food might trigger IBS symptoms.

#1 Fat content

Fast food tends to be rich in fat (1). Although fat is not a type of FODMAP, it can trigger IBS symptoms. However, the tolerance level differs from person to person.

A high-fat meal prolongs transit time through the intestines (2). This results in impaired gas transit, which IBS patients feel like (3):

Fullness
Bloating
Nausea

Consuming a meal rich in fats can also activate the gastrocolic reflex, prompting the bowels to open.

The fat content of some typical fast food items:

‘Big King’ from Burger King: 30g
‘Pizza Margherita’ from Pizza Hut (whole, medium size): 48g
‘Chicken Sandwich’ from Burger King: 39g

#2 FODMAP content

Fast food might trigger IBS symptoms also due to the FODMAP content (4).

Sometimes, FODMAPs are hidden in so-called “natural flavors,” which contain high FODMAP ingredients, such as garlic.

Common high FODMAP ingredients in fast food:

Wheat
Milk
Onion/onion powder
Garlic/garlic powder
High fructose corn syrup

In this section, we will share some valuable tips to follow so you can enjoy fast food with fewer or no IBS symptoms.

How to check the ingredient list

Menu ingredient lists can be complicated to study in a busy fast-food restaurant as they might not be readily available.

We suggest visiting the restaurant’s website in advance. You can then check the menu and search for the ingredients list to detect FODMAPs.

Checking the ingredients of seasoning is equally important. For example, french fries are made from potatoes fried in oil, so the dish is low FODMAP.

However, commonly added ingredients include onion and garlic for seasoning.

Check your condiments

When ordering your meal, pay attention to the condiments as well. As always, check the ingredient list to see if any high FODMAP ingredient (e.g., garlic) has been added.

Suitable low FODMAP options that have been tested (5):

Mayonnaise
Mustard
Ketchup

IBS suitable drink choices at fast food restaurants

Fizzy drinks such as cola or lemonade may trigger symptoms due to carbon dioxide and high fructose corn syrup.

In IBS, drinking fizzy drinks can result in a buildup of gas in the gut, which can result in bloating or pain if you are sensitive.

If this is the case for you, try choosing low FODMAP fruit juice or water.

When drinking juice, limit its intake to 150 ml a day, which is a general recommendation for a healthy diet (6).

Is McDonald’s low FODMAP?

The only low FODMAP option in McDonald’s is fries and a 100% beef patty with a slice of American cheese (a burger without the bun and onion).

In some countries, such as Holland, McDonald’s offers a gluten-free bun, which would also be suitable, but this is not widely available worldwide.

100% beef patty is seasoned with salt and pepper, making it FODMAP-friendly. If you like burgers, bring a low FODMAP bun from home and make one.

Is Sonic low FODMAP?

The absence of a publicly available ingredient list on their website makes it difficult to ascertain whether the Sonic menu items align with a low FODMAP diet.

Without clear information, we are left in the dark about the specific ingredients in Sonic’s offerings.

Low FODMAP Taco Bell options

When navigating Taco Bell’s menu on a low FODMAP diet, it is crucial to know that most dishes incorporate onion or garlic, both high in FODMAPs.

For a safe and flavorful experience, focus on specific low FODMAP options like jalapeños, bacon, cheddar cheese, lettuce, and tomatoes.

These ingredients provide a flavorful assortment without triggering IBS symptoms.

Low FODMAP Chick-fil-A options

FODMAP-friendly options on the menu include small hash browns and waffle potato fries.

Unfortunately, most of Chick-fil-A’s offerings feature ingredients like:

Onions
Garlic
Molasses
High-lactose dairy

Low FODMAP Burger King options

At Burger King, the limited safe foods for people with IBS include a hamburger without the bun, the garden side salad, and an ‘enormous omelet sandwich with ham’ (stripped of its bun).

Most dishes contain one or more high FODMAP ingredients, which can also be hidden behind “natural flavors.”
