What is Low FODMAP? What is Not?
As a Monash University FODMAP trained RD, curator of several low FODMAP grocery lists and low FODMAP support group moderator, I am often asked about natural flavors, artificial flavors, spices and flavorings (flavourings) that are commonplace on food labels.This article, How To Decipher Natural Flavors & Spices on Food Labels for the Low FODMAP Diet, will hopefully shed light on this confusing, and sometimes debatable subject.
A Global View
I have included an international perspective since food label regulations vary from country to country. The following FODMAP trained dietitians helped contribute to this article and reviewed my interpretation of the international food labels to ensure they were accurately represented:

USDA & the FDA
Let’s first review the two governing agencies of the United States (US) Food Label – the FDA and the USDA.
The USDA regulates meat, poultry and eggs, which also includes products that contain 2% or more of a cooked meat or 3% or more of a raw meat. The FDA oversees all other food products.Fun Fact: Once the egg is broken out of the shell it falls under the FDA, therefore cake mixes, cookies, and egg whites all fall under the FDA. Click To Tweet
Let’s Discuss Natural Flavors/Flavoring/Flavouring
The USDA guidelines per the Code of Federal Regulations Title 9. 317.2 state that whole, broken, or ground garlic, celery, and onion must be declared on the food label and cannot be hidden under the word “spices” or “natural flavorings”.
However, garlic powder, onion powder, and celery powder can be hidden under the term “natural flavors”, “natural flavorings”, and “flavoring” on the food label.
Note: I am not concerned with celery powder from a FODMAP perspective since it is unlikely that this equals more than ¼ (10 g) of a celery stalk.
Based on the FDA guidelines CFR – Code of Federal Regulations Title 21, the term natural flavor or natural flavoring means the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional. Natural flavors, include the natural essence or extractives obtained from plants listed in subpart A of part 582 of this chapter, and the substances listed in 172.510 of this chapter.
By definition the term natural flavors is a bit ambiguous and may possibly include a high FODMAP fruit or juice, garlic powder, onion powder, inulin or chicory root.
Based on multiple conversations with food manufacturers garlic and onion are often hidden under natural flavors in processed meats, broths, and other savory foods.
Let’s say the natural flavors do in fact contain a high FODMAP ingredient; it is impossible to determine how much of this ingredient was added and whether or not the amount is high enough to induce a symptom – especially since Monash also has very small Green Light serving size of many high FODMAP items (such as the garlic in Worcestershire sauce and ketchup).
Let’s Talk About Inulin & Chicory Root
On a rare occasion I have heard that inulin and chicory root were present in the natural flavors (these ingredients yield a sweet taste) however, the quantity present is likely very small and unlikely to trigger an IBS symptom.
I frequently see inulin and chicory root added to yogurts, kefirs, herbal teas, gluten free breads, and cereal, however these are typically declared on the food label.
What Does “Less Than 2%” Mean on a Food Label?
As you look more closely at many US food labels you may notices some foods are present in quantities less than 2%. The US food labels list food ingredients in order from greatest to smallest amount. The ingredients listed towards the end of the food label are only present in minute amounts.
If they are less than 2%, this will be identified as such. Natural flavors found on the food label in quantities less than 2% are unlikely to trigger IBS symptom and do not need to be avoided.
It would be advised to avoid a prepared food item if garlic or onion is listed anywhere on the label, even in quantities less than 2% during the Elimination Phase since even this small dose can trigger an IBS symptom in some sensitive individuals.
On the other hand, many individuals with IBS can tolerate high FODMAP foods that are present in such small amounts.
Work with your health professionals to determine your best approach.
The Australian Food Label
This information provided was obtained from the document, “Standards Australia and New Zealand Ingredient Labelling of Foods User Guide to Standard 1.2.4 – Labelling of Ingredients”.
An Australian ingredient list contains percentages of the main ingredients, also called “characterizing ingredients”, which are listed in descending order based on their weight.
Garlic & Onion and Compound Ingreditents
Garlic and onion are often declared on the food label, however this is not the case if they are used in a compound ingredient (an ingredient that is made up of two or more ingredients) that makes up less than 5% of the total weight of the food.
For example, if curry paste is contained in a food in a quantity less than 5% it can in fact contain onions, garlic, tomatoes, etc. and these ingredients do not need to be declared since they fall under a compound ingredient.
An exception to this is a food allergen – neither garlic or onion are considered as such. The allergens that must be listed include peanuts, tree nuts, milk, eggs, sesame seeds, fish and shellfish, soy, wheat and lupins.
Natural Flavourings & Spices
The term “Natural flavourings” or “flavour” can be used on a food label without having to declare the specific content or food additives present.
If “spices” or “natural flavouring” or “flavourings” are listed on the label in quantities less than 5% it is very unlikely that this trace amount of a high FODMAP ingredient, if actually present, would NOT be enough to trigger an IBS symptom.
If “spices” or “natural flavouring” or “flavourings” are listed on the label in quantities greater than 5% read the label and avoid if high FODMAP ingredients are present since they are often declared.
Joanna Baker ADP/AN/RN from Everyday Nutrition states, “The only exception I tend to suggest avoiding is “vegetable powder” or “dehydrated vegetables”, which are almost certainly onion and garlic. I do recommend avoiding these completely in the Elimination Phase of the low FODMAP diet.”
The United Kingdom & European Food Label
Labeling requirements for the UK and Europe fall under the EU Food Information to Consumers Regulations and the Food Information Regulations.
In the European Union (EU) all food additives must be identified on the food label with the specific additive name or an E code/number such as E967 or xylitol. The E stands for Europe.
While there may be some food additives that trigger symptoms in sensitive individuals, polyols or sugar alcohols are confirmed high FODMAP ingredients that are to be avoided in the Elimination Phase. Here is a list of polyols and their corresponding E numbers to look out for when reading the food label.
- E 420i – Sorbitol
- E 420ii – Sorbitol syrup
- E 421i – Mannitol
- E 953 – Isomalt
- E 965i – Maltitol
- E 965ii – Maltitol syrup
- E 966 – Lactitol
- E 967 – Xylitol
- E 968 – Erythritol
(Note that while erythritol is indeed a polyol, Monash University has determined that both erythritol and glycerol do not typically trigger IBS symptoms as they are more easily absorbed in the small intestine than other polyols).
Allergens such as nuts, gluten, soy, and lactose must be declared on the food label.
However, it is not always necessary to avoid foods with lactose since a low FODMAP diet is not a lactose free diet. If the label contains 1 gram of lactose or less, it is suitable for the Elimination Phase. Also, if a lactase enzyme is present among the ingredients, the product is considered lactose free.
So What About Natural Flavors and Spices in the UK & EU?
Natural flavors are defined in the EU in regulation (EC) 1334/200: Flavouring preparations are flavourings other than defined chemical substances obtained from materials of vegetable, animal or microbiological origin, by appropriate physical, enzymatic or microbiological processes, either in the raw state of the material or after processing for human consumption. Natural flavouring substances correspond to substances that are naturally present and have been identified in nature.
If a specific ingredient or a category of ingredients such as flavorings makes up less than 2% of the total food weight it does not need to be declared on the food label, the QUID (Quantitative Ingredient Declaration) does not apply in these circumstances.
Basically, garlic, onion, or any other high FODMAP ingredient may be present in amounts less than 2% of total ingredients are NOT declared on the food label.
This trace of a high FODMAP food is very unlikely to trigger an IBS symptom, so need not to worry if you see the word spices or natural flavors in quantities less than 2%.
The Canadian Food Label
Food labels are regulated by the Canadian Food Inspection Agency. In Canada the terms, “flavoring”, “spices”, “seasoning” or “herbs” are all exempt from having to declare their specific ingredients, which may contain garlic and onion.
When these terms are listed as the last ingredient, it is unlikely that if the product contained onions or garlic, the amount would trigger IBS symptoms, per Canadian based RD, Audrey Inouye.
It is best to avoid foods containing glucose-fructose (also known as high fructose corn syrup) and fructose during the Elimination Phase.
Seasonings that are found in a seasoning preparation in quantities less than 2% of the total weight are exempt from declaring specific ingredients, however, if present in quantities greater than 2% they must declare the included ingredients.
Take Home Notes Regarding the Term “Spices”
- Per FDA and USDA guidelines, the word “spices” on the US Food Label – cannot contain garlic or onion, however this is not true for other countries.
- If a food product in Australia, UK, or Europe (and outside of the USA) contains the word“spices” please contact the manufacturer to inquire if garlic or onion are in fact present or avoid during Elimination.
- If a food product in Canada contains the word “spices” it is not necessary to avoid if it is listed as the last ingredient. When the word “spices” is NOT the last ingredient please contact the manufacturer to inquire if garlic or onion are in fact present or avoid in Elimination.
- If a food product lists garlic and onion on the food label in any quantity, even when less than 2% or 5%, it is advised to avoid this food item during the Elimination Phase unless it is low FODMAP certified or has a Green Light portion as listed per the Monash app, such as in the case of ketchup.
Take Home Points Regarding the Term “Natural Flavors, Flavors, Flavoring & Flavouring
First and foremost, ALWAYS listen to your dietitian or health care provider if they have made recommendations on how to treat “natural flavors”.
- It is not necessary to avoid food products in the US when natural flavors are present in quantities less than 2%.
- It is not necessary to avoid natural flavors in Australia if present in quantities less than 5%.
- It is not necessary to avoid natural flavors in the UK and Europe if present in quantities less than 2%.
- It is not necessary to avoid natural flavors in Canada if listed as the last ingredient.
In these situations if an actual high FODMAP ingredient is in fact present, this minute portion is unlikely to trigger an IBS response. It is important to remember that several foods containing garlic and onion have a Green Light pass from Monash. I would like to also quote Joanna Baker APD/AN/RN from Everyday Nutrition:
When natural flavors are present higher up on the food label in a savory food you may want to avoid during the Elimination Phase or call the manufacturer since these are more likely to contain garlic and onion. I would be less concerned about avoiding natural flavors in a sweet food, such as candy.
It is probably best to avoid ALL foods with natural flavors in amounts greater than 2% to 5% if you have been unable to achieve adequate symptom control. You can also always call or email the food company to ensure no high FODMAP ingredients are present if you have concerns.
What About Artificial Flavors?
Now let’s quickly review artificial flavors. Here is how the FDA defines artificial flavoring:
“The term artificial flavor or artificial flavoring means any substance, the function of which is to impart flavor, which is not derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, fish, poultry, eggs, dairy products, or fermentation products thereof.” Basically, artificial flavors impart the flavor of a food, such as an apple without using a real apple. By definition, I consider artificial flavors low FODMAP, across the globe.
