Why is honey not gluten-free?

Honey is a sweet, viscous food substance made by honey bees and some related insects. It is produced from the sugary secretions of plants or insects, such as floral nectar or aphid honeydew, through regurgitation, enzymatic activity, and water evaporation. Honey is a very popular food product known for its sweet taste, medicinal properties, and long shelf life. However, there is some debate around whether honey can be considered gluten-free or not.

What is gluten?

Gluten is a general name for the proteins found in wheat, rye, barley and triticale. It acts as a “glue” that helps foods maintain their shape and texture. The two main proteins that make up gluten are gliadin and glutenin. When people with celiac disease or non-celiac gluten sensitivity eat gluten, it triggers an immune response that attacks the small intestine and causes inflammation and damage. This leads to a variety of gastrointestinal and other symptoms. For people with gluten-related disorders, following a strict lifelong gluten-free diet is essential to manage symptoms and prevent further complications.

Why might honey contain gluten?

While pure honey does not naturally contain gluten, there are a few ways that gluten can inadvertently be introduced:

1. Cross-contamination during processing and handling

Most commercial honey goes through extensive processing and handling before it reaches grocery store shelves. If equipment or storage facilities are shared with gluten-containing foods like wheat, barley or rye, then cross-contamination is possible. Small amounts of gluten could be transferred into batches of honey through shared conveyor belts, mixing vats or storage tanks. Proper cleaning protocols and dedicated facilities/equipment for gluten-free foods are necessary to prevent this.

2. Addition of gluten-containing ingredients

Some honey products have additional ingredients added, like flour, wheat starch or cereal grains. These ingredient additions can introduce gluten into honey. Reading ingredient labels carefully is important to identify added sources of gluten.

3. Pollen contamination

Since bees harvest nectar and pollen from many different plants, there is a chance that gluten-containing cereal grains like wheat, barley or rye could be inadvertently introduced into honey through pollen. However, multiple studies have detected only trace amounts of pollen or gluten in raw honey, not likely enough to cause issues for most people with gluten intolerance.

Is all honey contaminated with gluten?

No, most pure, raw honey does not contain high enough levels of gluten to cause problems. Here are some pointers on selecting honey that should be gluten-free:

– Look for certified gluten-free honey. Reputable brands will often state certification or label honey as gluten-free if they follow gluten-free processing practices.

– Opt for pure, raw honey. Raw honey is less processed so there is less likelihood of cross-contamination. Raw honey also contains pollen, so you can see visible grains that show the floral sources.

– Avoid additives like malt syrup, barley malt, wheat starch, flour or cereal grains. Check the ingredients label to ensure no gluten sources have been added.

– Buy local honey from a trusted beekeeper. This has a lower risk of cross-contamination compared to mass-produced commercial honey.

– Contact the honey company. Reputable brands should be knowledgeable about their processing and be able to verify that the honey is gluten-free.

Why are some organizations/regulators hesitant to classify honey as gluten-free?

While most honey is considered gluten-free, there are a few reasons why some regulatory bodies or allergen control organizations take a cautious stance:

Possibility of cross-contamination

As mentioned, there is always a risk of gluten cross-contamination during large-scale processing of honey involving shared equipment. So even though honey does not inherently contain gluten, traces could potentially make their way in. Some organizations want to see companies implement rigorous controls and gluten-free certification processes before labeling honey definitively as “gluten-free”.

Lack of regulated standards

Currently, there are no regulated legal limits for the amount of gluten allowed in order for a food to be labeled “gluten-free”. Different countries and organizations have set advisory levels ranging from 20-100 ppm (parts per million). However, without standardized regulations, some organizations are hesitant to formally classify all honey as gluten-free when these limits are unclear.

Allergen control mindset

For facilities managing allergens like gluten, the overriding concern is safety of customers with food intolerances. Even minute amounts of allergens can trigger reactions in sensitive individuals. Therefore, some facilities take a broad approach of considering anything that has come into contact with gluten as an off-limits allergen, including honey. They want to see rigorous protocols before calling honey completely gluten-free.

Possibility of added ingredients

As mentioned, some processed honey products may contain added sources of gluten like wheat starch. So blanket classification of ALL honey as gluten-free could be inaccurate without careful label reading to check for potentially problematic ingredients.

Testing shows most honey is gluten-free

While being cautious about labeling honey as definitively gluten-free, scientific testing shows honey is highly unlikely to contain harmful levels of gluten:

– A study published in the Journal of Food Protection examined 36 raw honey samples from Canada and the United States. Gluten levels were below the detection limits of 5 parts per million for all samples.

– Researchers in Italy analyzed 45 honey samples, including some made from wheat-based crops. The highest gluten level detected was 8 ppm, well below amounts considered unsafe for those with celiac disease.

– Another study looked at 119 honey samples from Greece. The majority (105 samples) had undetectable levels of gluten, while 14 had trace amounts between 5-8 ppm.

– The United States Pharmacopeia looked at 70 different honey samples and found the average gluten content was less than 5 ppm.

So while detectable gluten may be present in some honey samples in trace quantities, testing shows these levels are far below amounts considered unsafe for consumption by those with gluten intolerance. The majority of pure, raw honey appears to be gluten-free to the limit of detection.

Should people with celiac disease or gluten sensitivity consume honey?

This depends on the individual and their sensitivity levels:

– People with confirmed celiac disease need to follow a strict gluten-free diet with no detectable gluten. Consuming honey may involve some low-level risk depending on processing. They should consult their doctor and dietitian about including honey in their diet.

– Individuals with non-celiac gluten sensitivity can often tolerate trace amounts of gluten. Pure honey containing very low levels (under 10-20ppm) is likely fine for many based on research. However, they should watch for any adverse symptoms.

– People undergoing initial testing for celiac disease need to continue eating gluten daily during the testing process. So they should avoid honey until a diagnosis is confirmed and gluten is completely eliminated.

– For those with wheat allergies, honey should be safe since it does not contain wheat proteins. But other cereal grain allergies like rye or barley may necessitate caution.

Overall, individuals need to weigh the very low risk of gluten exposure from properly sourced honey compared to the potential benefits honey can provide. People who must follow gluten-free diets should work with their healthcare teams to make informed decisions about including gluten-free labeled honey.

Precautions when selecting honey

Here are some tips for safely selecting honey if you need to avoid gluten due to celiac disease or gluten intolerance:

– Opt for honey labeled certified gluten-free, which indicates the company adheres to gluten-free processing practices and protocols to prevent cross-contamination.

– Choose raw, unpasteurized honey over processed or heat-treated honey. Raw honey is less likely to be contaminated during minimal processing.

– Avoid added ingredients like flour, malt syrup or grain-based components. Check the ingredients label to ensure no gluten sources.

– Look for smaller-batch local honey from a trusted source or beekeeper. These have less risk of gluten contamination than large commercial operations.

– Contact the company to ask about their manufacturing process and how they ensure honey is gluten-free. Reputable brands should supply this information.

– If concerned, choose lighter-colored honey varieties, which are less likely to contain pollen grains.

– Do not consume honey from bulk bins or barrels due to risk of cross-contamination from scoops. Opt for honey packaged in sealed containers.

– Children should avoid honey until at least 12 months old due to risk of infant botulism from Clostridium spores sometimes found in honey.

Potential reactions to honey

While rare, there are a few reasons someone may experience adverse reactions after consuming honey, even if the honey is gluten-free:

Fructose intolerance – Honey contains significant fructose, which some people do not properly absorb. This can lead to symptoms like bloating, gas and diarrhea.

Infant botulism – Infants under 12 months can develop botulism from Clostridium spores in honey. Honey should be avoided for the first year of life.

Bee pollen allergy – Those allergic to bee pollen may react to trace amounts in raw honey. Processed honey with pollen removed is an option.

Added sugars sensitivity – People with issues managing blood sugar levels may need to moderate honey intake due to its high sugar content.

Salicylate sensitivity – Honey contains some salicylates, compounds occurring naturally in many plants. Those with salicylate intolerances may need to avoid.

Underlying IBS/IBD – People with conditions causing intestinal inflammation may experience discomfort from any concentrated sugars, including honey.

As with most foods, there are some individuals who may not tolerate consumption of pure honey well. Allergy testing can help identify these sensitivities. Most people can safely enjoy gluten-free honey.


Honey makes a delicious sweetener and beneficial health food for most individuals following gluten-free diets. When properly sourced, raw varieties of honey contain only trace amounts of gluten far below the accepted thresholds for safety. However, those with celiac disease and marked gluten sensitivity should exercise caution and consult with their physician when adding honey to their diet. Careful label reading, choosing certified gluten-free honey, and contacting manufacturers can further minimize any risk of gluten exposure from properly processed honey. With its multitude of nutrients and health-promoting compounds, quality gluten-free honey has much to offer people avoiding gluten.
