    i don’t know ifit’s thespray theyuse,oranything buteven someapples give methis,buti still don’t know why.

  • Someallergies cantake justthetouch ofthefood tomucus membranes tostarta reaction inseconds.

  • well Mostfood algerys caneven startassoon asyouputitnear yourmouth.Anything isPossible maybe yourbody isnow getting used toeating themsinceyouhavehadthembefore.

  • i havea LOT ofallergies. i amallergic tonuts very badandi ate a chocolate witha nut inthata didn’t notice,10 seconds afterdigesting gave mea badfeeling inmythroat anda few more seconds later i wasviolently sick andcouldn’t breathe very well andneeded tocall anambulance 10 seconds later. i thinkitshowbadtheallergy,thequickeritstartstotake effect.

  • There’s noone answer. Itdepends ontoomany factors such aswhatyourallergies areandhowsevere theyaretocertaintypes offood,insect stings,andthelike. Ifyouarereally allergic tobee stings orfire ant bites (goes forsnake bites too),youhaveabout15 minutes toanhour,maybe less. Itdepends onwhereyougotstung orbitten (close toanartery ornot).Keep a steroid handy asyoumaynothavetime torecover. Peanuts cancause systems inless thanthana few minutes aftereating them. Peppers generally take 6 to12 hours forsystems toshow,but,again,itdepends onhowmuch youconsumed andhowallergic youaretothem. I’d stay away fromthepeppers.

    Youdon’t give yourage,soitispossible,ifyouareyoung,togrow out ofcertainallergies asyougetolder. Becareful!

  • Allergies aregenerally weird. One minute youcouldbeallergic tosomething andthenext minute theallergy disappears!

    Food allergies areespecially weird. I used togetsick everytime I ate crab –butnow I’m notanymore. Kiwi alsomakesmylips &tongue feel fuzzy,butthisisa recent development forme.

    Thething isthatyoucan‘outgrow’food allergies. Otherallergies canlast yourwhole life,although theymaybeless severe andmore severe atdifferent points inyourlife.

    Sounds likeyourbody islearning howtocope withyourreaction topeppers and/oryou’re becoming less sensitive!

  • Itwillreally depend onthestrength oftheallergy.
    Itwillalsodpend upon thecondition ofyourbody atthetime theallergy occurs.
    Itcoulddepend onwhatotheritems youconsumed prior to,during,orshortly aftereating theallergy food. Chemicals infood react differently witheach otheranddifferent combinations.
    Itcouldbetheamount oftheallegy food youconsumed.
    Itcouldbeinstantaneous orhours

    Sometimes people grow out ofallergies.

  • 4 hours. That’s normal. Here’s anidea;howaboutstopeating those foods thatyou’re allergic to?! lol
