I get an itchy face when i eat peanut butter but not normal peanuts?

Some thing in: peanut butter. You may be allergic to an additive in peanut butter that is not normally present in peanuts per se. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine.

Interesting: I don't see the few extra agents present in peanut butter being the likely allergens and thus suspect that you may be allergic to a tree nut which has contaminated the processing equipment-most manufacturers process several nuts in the same equipment. Consider getting tested to tree nuts.
