Most will say the allergic reaction has to do with a mould/fungus on certain nuts, all I know is that I was born allergic to Coconut and for 40+ years it would make my throat swell and sometimes just stop breathing if I just ate a small hidden piece within a food, etc....and then after my first 40 day orange juice fast this lifelong problem faded away.............
I believe if our lymph glands are cleaned out and we are not loaded with mucus, our body can tolerate allot more not so human foods..
