And anything else that you are allergic to. Are you doing this for the purpose of losing weight? You must make a conscious effort not to do this. If part of you wants to lose weight and is using this, it might be more difficult to break.
A good step would be to clear your house of offending products. If you live with others, perhaps you or them could put all the offending products in one cupboard or something so you wouldn't reach for them. Wheat and eggs are in a lot of things, but not everything. Buy fresh meat, vegtables, and rice. If you are still problems with a good meal plan, talk to a doctor or dietician. Also take a multivitamin.
It is best to get these things under control as soon as possible. I don't know if you have an eating disorder from this post, but eating disorders can spring up from bad eating habits and get worse the longer that you do them. The weaker you get, the harder it can be to act in your best interests.
