Flax seed allergy in children: an emerging allergen?

Article metrics

  • 3755 Accesses

Background

Flax is a plant that is widely cultivated and has multiple uses. The seed has been increasingly used in food, and the fibers are used in textiles. Oils have also been extracted from the seed for use as a laxative and in industrial preparations. Allergic reactions to flax seed ingestion as well as linseed oil (flaxseed oil) ingestion have been described in the literature in adults (1-5), but not in children.

Material and methods

We report four cases of flax seed allergy in children.

Results

See table 1

Table 1 Table 1

Conclusions

Few cases of flax seed allergy have been described in the literature. As the use of flax seed in foods becomes more prevalent, this will likely become a more important cause of allergic reactions in the future.
