Several years ago, I wrote a page about the use of honey for treating allergies. However, (and especially if you suffer from allergy to pollen) you may be wondering whether it is possible to be allergic to honey.
This is a legitimate concern, given that honey is made from nectar gathered by bees from flowers.
The short answer is:
Yes – it is possible to be allergic to honey and to experience typical symptoms of allergic reaction (even anaphylaxis in extreme cases) after eating honey. However, allergic reactions caused by eating honey are very rare.
There are a number of case studies describing such incidences.
It is thought that allergy to honey can
be caused by two things:
A study by Bauer2 in 1996 of 23 patients who exhibited allergic reaction to honey consumption ranging from mild itching to anaphylaxis demonstrated this quite clearly – proteins secreted by honey bees (from the pharyngeal and salivary glands in the head) and proteins from any pollen within the honey were the causes of allergy to honey.
Yes. Vezir et al3 in 2014 described 6 patients who had systemic allergic reactions after eating honey – three of them suffering anaphylaxis.
Honey-specific immunoglobulins (specifically IgE – the primary protein produced by the body that leads to the allergic reaction symptoms) were found in all six patients – so the honey was producing a genuine allergic response.
The allergic response to honey can vary from very mild to very severe.
At the mild end of the spectrum, symptoms might include mild itching within the mouth, or mild itching of the skin.
Some people have experienced more severe skin reactions after eating honey – urticaria or pruritis, for example.
In the event of anaphylaxis after eating honey, this is an emergency, and immediate medical intervention is required. Anaphylactic reaction is a potentially life-threatening condition. Seek emergency assistance if any of the following symptoms occur:
Yes, particularly if unfiltered to remove pollen. Di Costanzo et al1 reported a case of anaphylaxis in a five-year-old boy after eating an ‘artisanal’ honey.
The vast majority of commercial honey offered for sale at the average retail store is filtered and pasteurized so that most of the pollen is reduced, but this would not be the case with an artisan honey.
A study by Helbling4 in 1992 of 22 patients with a history
of systemic allergic symptoms after eating honey, showed that pollens in the
honey were responsible for a high proportion of the allergies.
For example, 75% of the sample were allergic to dandelion pollens, and 59% allergic to pollens from the Compositae family – a family of plants that includes over 32,000 flowering plant species.
So the suggestion is that subjects with a known allergy to a wide range of plant pollens have a higher likelihood of suffering an allergic reaction after eating honey.
There have been case reports of allergic reactions after eating royal jelly. Katayama et al5, Takahama6, and Harada7 have all reported cases of anaphylaxis caused by royal jelly.
So the answer is: yes – eating royal jelly can cause allergy and anaphylaxis.
