Am I allergic to high proteins?

Dear doctor; Growing up, I always had a problem eating eggplants or silver fish. Any food with these foodstuff mixed would be too compelling for my metabolism. Even the smell of the broth cooking would leave me nauseated. I stopped eating them. I understand it was because these eggplants and silver fish have too much protein content. But in adult life, I have it hard eating matooke (plantains) mixed with ground nut stew. Whenever I try, I get stomach upset. Are these some weird allergies?
