Rapeseed is a low FODMAP food. 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.
Rapeseed is a food low in histamine, so is suitable for people following low histamine diets.
Rapeseed contains a moderate amount of lectins
, another cause of food intolerance. Cooking foods with lectins makes them more digestible and can reduce the symptoms of food intolerance. As canola/rapeseed oil is highly processed it is unlikely to cause a problem with people who suffer with lectin intolerance.
