Does anyone know why peanut butter makes me break out?

Slight allergy to peanuts.

Are you serious??? that sucks!!!

No he's Shirley....

Yes, It happened to my mom, then to my brother & sister a few years apart....thought it had skipped me, but alas, about 6 months ago it started to do the same to me...sad, cause I really like peanuts.

It's because you are young.

And don't call me Shirley.

I'm not so young anymore, I'm 27
It's always been this way, even when I used to be overweight. Am I really allergic?

it's probably a bit toxic to your body... Fruitopia made me break out around my butt and groin until I figured out there was something about grapes/strawberries/watermelon

This really sucks. I really wanted a PB and Jelly sandwich right now. I stopped eating it for years, but recently I bought two different brands. One has chunks of peanut in it. That's been the worse one, it makes me break out with HUGE pimples, the size of Texas.

People's allergies can change over time...usually on a seven year cycle and there are varying degrees of allergenic reactions.

Your reaction to PB seems mild at the time...might even be that peanut oil is not a friend to your skin. however, that being said...allergies could become more deadly at any time...the next time you eat a peanut product my very well put you into anaphalaxis.

You should see a dermatologist to get a clear cut answer...until you see one...avoid all peanut products altogether.
