MAPLE SYRUP ALLERGY
Maple syrup is collected from the sap of maple trees. Maples are in the Sapindaceae
family of plants. Other edible plants in this family include gurana, ackee fruit and lychee.
foods contain Profilin proteins
, the way that maple syrup is processed by boiling would mean that these are unlikely to be found in maple syrup as these proteins are easily broken down by heat and processing.
Most recorded reactions for maple syrup have been from people who already suffer from a pollen allergy to maple pollen
Outside of Canada there are a lot of 'fake' maple syrups, you should check ingredients, those that are not genuine will contain multiple ingredients and these should be considered if you think you are allergic to maple syrup.
Genuine maple syrup is a food low in histamine
, so is not suitable for people following a low histamine diet.
Fake maple syrups may be high in sulphites
, but the genuine article is not. Sulphites are inorganic salts used in preservations and have the potential to cause symptoms of food intolerance to those sensitive to sulphites, this food intolerance is more common in asthmatics. An improvement in symptoms can be made with a change to a low sulphite diet.
Maple syrup is a low FODMAP food when eaten in normal portions. FODMAP
stands for F
olyols. Foods high in FODMAPs can cause symptoms of food intolerance, affecting the gastro intestinal system and this can be mistaken for a true IgE food allergy.
Maple syrup is also low in salicylates
. Salicylates have the potential to cause worsening of asthma, swelling, itching and hives as well as food intolerance symptoms in people who are sensitive to salicylates.
