I've been eating Paleo for about three or so months and I'm overall pleased with the results. But I've noticed a pattern and kind of confused by it...As of late every time I eat beef (usually for dinner) I wake up the next day to an upset stomach that feels like it's on fire!!! The pain stays for the better part of the day...Sometimes I have diarrhea associated with it but not always..does this mean I'm allergic to beef? I've never had this problem before and it's only started since eating Paleo...does anyone know why this could be??
I'm allergic to beef and I get the same thing (minus the fire), but I'd suggest you first remove it from your diet and give yourself some time to heal (eat chicken, fish, pork in rotation).
Then when you feel well enough to potentially take a few steps backwards, try introducing some beef in your diet. They say you should eat it 3 times a day for 3 days (size of your palm) when introducing things back in to test for allergies.
You'll know if you get the same reaction, but it can take up to 3 days. I still try every year and I react within 12 hours to it.
Hopefully its just a digestive issue and nothing more. If thats the case, try rotating your meats so you don't eat the same protein too often.
best of luck and feel better!!!
(sometimes going paleo opens you up to undiscovered issues you didnt know you had...meaning eating clean can cause you to react to things you never reacted to before)
