GUARANA ALLERGY
Key Allergens
Guarana is a plant in the Sapindaceae family of plants. Other plants in this family include ackee fruit, lychee and maple trees.
The seed from the fruit is used as a dietary supplement and additive as it contains more caffeine than coffee beans. It also has theobromine and theophylline which are also stimulants.
Food Intolerances

Guarana is usually consumed in such small doses that it is not associated with any food intolerances.
Caffeine is a low FODMAP food, but is not recommended for those eating a FODMAP diet due to IBS as it can also be an irritant.
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.
