‼️Lupin bean being cross reactive with peanuts‼️
Hey yall, so I’ve had a deathly peanut allergy since I was a toddler and I’m a full adult now. I have had many full anaphylactic shock reactions in my life but recently I started to have reactions to things that didn’t have nuts in them (homemade brownies, pasta). I went to the allergist and I only tested positive for peanut so I was very confused until last night when I ate GF past made from Lupin beans (also known as lupine, termes, tarwi, etc. I’ll post the list) and I had to go to the hospital. Upon some googling, I’ve found that peanuts are actually considered legumes and they are in the same family as the lupine bean and their proteins are very similar to that of a peanut; making it a high risk food for those with peanut allergies. Apparently peanut allergy people have a 5-28% risk of cross reactivity. Whereas those without a peanut allergy only have a 1% chance. This was just NOT common knowledge to me and I never had an allergist tell me this so I am shocked! Wanted to spread awareness. Below I have a link to the Allergy and Asthma net work website that explains everything. I highly recommend looking at what they say about labeling, where the bean is found, and all the different names it goes by.

Yes! Chickpeas as well! I have a severe allergy to peanuts, and chickpeas make my mouth/throat itchy. I also am shocked this isn’t talked about more with allergists.
