If you accidentally ingest some food that you are intolerant to and there is no danger of a severe reaction, some of the following may help.
Digestive enzymes can help the body break down all foods and some people find that buffered vitamin c helps after a reaction. Quercetin can also reduce the symptoms of a reaction and can also prevent them.
I'll include links to three amazing products we have in the store here that can help when exposure to allergens is inevitable or has already happened. I don't recommend eating allergens if you can help it and sometimes, depending on your energy and blood sugar levels, waiting to eat may be less destructive to our health than eating an allergen but this is very individual.
Below are links to enzymes and Smooth Operator and to buffered vitamin C.
I hope this is helpful.
In good health,
