Those are some bad nuts.

I love NCBI ROFL. It’s one of the Discovery Blogs and every day they publish a humorous or absurd study. It’s like a mini-Ig Noble award to my Google Reader every day.

Yesterday there was a case of a woman who had an allergic reaction after having sexual intercourse with her boyfriend:

“Brazil nuts are the second most frequent cause of nut allergy in the United Kingdom. We report the case of a 20-year-old woman with documented Brazil nut allergy who developed widespread urticaria and mild dyspnea after intercourse with her boyfriend who had earlier consumed Brazil nuts. Skin prick testing with the boyfriend’s semen after Brazil nut consumption confirmed significant reactivity whereas a sample before nut consumption was negative. We believe this to be the first case of a sexually transmitted allergic reaction.”

Bad nuts, indeed.

Those are some bad nuts.
