Lupin is a legume from the same family as peanuts. Its high protein, high fiber, low fat composition makes it an ideal ingredient for many new gluten-free products. People with a peanut or soy allergy may react similarly to lupin, but may be unaware of its risk. Potential reactions include hives, lip swelling, vomiting, breathing difficulties or even anaphylactic shock.
PositiveTip: Read labels and avoid any products that contain lupin if you have a peanut or soy allergy.
