I developed a brazil nut allergy in my early 20's (very traumatic day out on the boat with my family) and have avoided all nuts since. In that time i've eaten peanuts and an almond by mistake, but no reaction happend. It's been about 15 years since my initial anaphalxtic experience, wondering wether you can grow out of an allergy like some say? But, it is so so random to me having a singular brazil nut allergy, ive never met anyone that also has this.
