Do you get different reactions from different food allergies?

I get very extremely smelly gas when I eat sauerkraut or soup made of a lot of different sugar-free vegetables.

Eating brown rice (even like a few grains, so not a candida reaction) or buckwheat causes diarrhea instead.

Do you ever have different allergy reactions when you eat different allergens?

There could be a different cause of me reacting this way, but want to know if it's possible that allergies could be the cause.
