I have a history of allergies and food sensitivities in my family, so I had to careful with what I gave my son. Besides true food allergies, some people are also sensitive to natural chemicals in food (salicylates, amines and natural MSG) so I introduced foods high in those chemicals later too. Some other allergenic foods to consider introducing later are tomatoes, berries and citrus fruit - I waited till closer to 12 months to introduce those. My son is allergic to kiwifruit and pawpaw (papaya). Also if there is any coeliac disease (gluten intolerance) in your family you might want to consider giving gluten containing foods after 12 months too - basically almost all grains except corn and rice (and a few others I can't remember.)
The foods I introduced first were pears, apples, potatoes, pumpkin, rice, sweet potatoes, peaches, carrots, parsnips, bananas, chicken.
Foods on that list that are high in amines and salicylates are caulifower, broccoli, avocado, raisins (also need to consider any sulphite preservatives on dried fruit too) and some others too, I don't have my book with me so I'm going on memory. The book is 'Friendly Food' but I'm not sure if it's available outside of Australia.
