Understanding Honey and FODMAPs
For individuals following a low FODMAP diet, understanding which foods can trigger symptoms is crucial. FODMAPs, which stands for Fermentable Oligo-, Di-, Mono-saccharides And Polyols, are a group of short-chain carbohydrates that can cause digestive issues like bloating, gas, and abdominal pain in sensitive people. Honey, a popular natural sweetener, contains a high concentration of fructose, specifically in excess of glucose, which is the primary FODMAP of concern.
When fructose is present in a higher amount than glucose, it is poorly absorbed by the small intestine in some individuals. This unabsorbed fructose then travels to the large intestine, where it is fermented by gut bacteria, leading to the production of gas and other symptoms. While all honey is high in excess fructose, the exact FODMAP content can vary significantly depending on the nectar source. This variability is why different types of honey have different low FODMAP serving sizes.
Specific Honeys and Their FODMAP Content
Monash University, the leading authority on the low FODMAP diet, has lab-tested various types of honey to determine their FODMAP content and establish safe serving sizes. The results show that some varieties are better tolerated in small quantities than others, but it is important to remember that 'low FODMAP' does not mean 'fructose-free'.
Generic Honey
According to Monash University, a standard, store-bought 'generic' honey is considered low FODMAP at a serving size of 1 teaspoon (7g). This is the most common variety tested and serves as a baseline for many individuals starting to test their tolerance.
Clover Honey
Made from the nectar of clover plants, this variety has a different fructose-to-glucose ratio than generic honey. Monash testing found that clover honey is low FODMAP at a smaller serving size: ½ teaspoon (3g). This lower tolerance threshold suggests that it contains a higher concentration of fermentable fructose per serving compared to generic honey.
Avocado Honey
This type of honey is made from the nectar of avocado blossoms and has a much darker color and richer flavor. Lab tests revealed that avocado honey has an extremely limited safe serving size, with a low FODMAP designation at just 1g. Any amount above this tiny portion would likely trigger symptoms in sensitive individuals.
Manuka Honey
Despite claims of significant health benefits, including potential anti-inflammatory and gut-supportive properties, Manuka honey is not a low FODMAP option. It contains high levels of excess fructose, just like other honeys. Additionally, the compound methylglyoxal (MGO), responsible for its unique antimicrobial effects, may even worsen symptoms like diarrhea in some sensitive individuals. Therefore, Manuka honey offers no advantage for managing IBS symptoms and may be more likely to cause distress.
Comparison of Low FODMAP Honeys
| Honey Type | Low FODMAP Serving (Monash) | High FODMAP Threshold (Monash) | Notes |
|---|---|---|---|
| Generic Honey | 1 teaspoon (7g) | Above 1 teaspoon | Most common variety tested. |
| Clover Honey | ½ teaspoon (3g) | Above ½ teaspoon | Lower tolerance threshold. |
| Avocado Honey | 1g only | Above 1g | Very limited safe serving. |
| Manuka Honey | No tested low FODMAP serving | High FODMAP | Avoid if sensitive to excess fructose. |
FODMAP Stacking: A Critical Consideration
Even when consuming a 'low FODMAP' serving of honey, it is important to be aware of a concept called FODMAP stacking. This occurs when a person consumes multiple low FODMAP servings of high-fructose foods throughout the day, and the cumulative effect exceeds their tolerance threshold. For example, having a half-teaspoon of clover honey in your tea in the morning and later eating a low FODMAP portion of a fructose-containing fruit could trigger symptoms. Tracking your intake and waiting several hours between fructose-containing foods can help prevent stacking and manage digestive symptoms effectively.
Low FODMAP Alternatives to Honey
If you find that even the small, tested amounts of honey trigger your symptoms, or you prefer a safer alternative, several low FODMAP sweeteners can provide the sweetness you crave without the digestive risk.
- Pure Maple Syrup: Derived from the sap of maple trees, pure maple syrup is low FODMAP in generous serving sizes, making it a reliable substitute for honey in many recipes.
- Rice Malt Syrup: This sweetener is made from fermented rice and contains no fructose, making it a gut-friendly option. It has a milder flavor than honey and works well in baking.
- Table Sugar (Sucrose): As a combination of glucose and fructose, table sugar can be low FODMAP in moderate quantities, typically up to 1 tablespoon, because the glucose helps facilitate the absorption of the fructose.
- Brown Sugar: Similar to table sugar, brown sugar is low FODMAP in moderate amounts and adds a richer, molasses-like flavor to dishes.
- Stevia and Monk Fruit Sweeteners: These non-caloric sweeteners are derived from plants and are generally considered safe on a low FODMAP diet.
The Final Word on Honey
Ultimately, the relationship between honey and the low FODMAP diet is not black and white; it is about individual tolerance. While Monash University has identified very small low FODMAP serving sizes for certain types of honey, many individuals with severe fructose malabsorption may not tolerate any amount. Therefore, the safest approach for those in the elimination phase of the low FODMAP diet is to avoid honey entirely. For those who have completed the reintroduction phase and have identified their tolerance to fructose, carefully measured, small servings of generic or clover honey might be acceptable.
For most people managing IBS, focusing on reliable, low FODMAP alternatives like pure maple syrup or rice malt syrup provides sweetness without the risk of triggering symptoms. Always listen to your body and consult with a registered dietitian to determine the best approach for your individual needs. The goal is to find a sustainable and satisfying way of eating that supports your digestive health.

Conclusion
In summary, while no honey is truly 'lowest in FODMAPs' due to its high excess fructose content, specific types have been tested and found to be low FODMAP in tiny, carefully measured servings. Generic honey has a low FODMAP serving of 1 teaspoon, while clover honey is limited to ½ teaspoon, and avocado honey to a mere 1g. Manuka honey is not low FODMAP and should be avoided. For a completely safe and symptom-free sweetening experience, low FODMAP alternatives like pure maple syrup, rice malt syrup, and table sugar are the best choice, especially during the elimination phase of the diet. Always consider your individual tolerance and the risk of FODMAP stacking when incorporating any amount of honey into your diet.
