Kale allergy is rare but not unheard of. Several people have reported a suspected kale allergy on this site.
It is possible to become allergic to almost anything of course, but some allergies are more common than others. Most allergies are suffered when people are highly exposed to the food. Some people report allergies to kale the first time they eat it. This does not fit the usual pattern of an allergy, but does not necessarily rule out an allergy either.
A more likely scenario is that someone became sick at the same time as trying the new food, and their body now associates that food with getting sick. This is not the same as an allergy. It is also possible that something else with the suspected food is causing the reaction.
Here are a couple of reports from people who think they have an allergy to kale:
I happen to love kale, but if I eat it, I suffer (from 8-24 hours later) severe cramps, chills, diarrhea, nausea, exhaustion….I feel like I have the flu. I get none of these symptoms from anything else in the kale family. And it doesn’t matter if it’s cooked, raw, baked, whatever. -Susie
I’ve eaten kale twice in my life. I made baked kale crisps and woofed them down one evening. Within hours I was nauseous, had stomach/intestinal cramps, achy muscles, and a fever of 101 degrees. A few weeks later I ate some kale in the school cafeteria and soon after experienced severe intestinal pains, achy muscles, and a fever of 100 degrees. Because I never get sick I was able to narrow down the reason I was sick was due to eating kale!!! Crazy. I’ve never heard of a kale allergy, but it’s good knowing others have experienced the same thing. -Jean
Kale is a member of the Brassica oleracea species. This includes the following cultivars:
- Brussels Sprouts
- Collard Greens
- Gai Lan
If you feel you are allergic to one of these but not others, it is unlikely you have an allergy.
