Blackberries are fruits in the Rosaceae family of plants. Other plants in this family include cherry, peach, pear, plum, almonds, apples, raspberries and strawberries.

They are not currently associated with food allergy. To date there are no recorded allergens for blackberries by the World Health Organization (WHO), because there have not been enough study into allergic effects from this food. If you are interested in what is needed by the WHO before they add an allergen to their allergen database you can check that out HERE.

Blackberries contain a lot of vitamin C, so if eaten in large quantities can cause gastrointestinal issues. This is a problem more commonly seen in babies and children as their vitamin C requirements are much smaller than adults.

Blackberries are a food high 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.

Blackberries are a high FODMAP food. FODMAP stands for Fermentable oligosaccharides, disaccharides, monosaccharides and polyols. 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.
