I would consider stopping the nuts because in time you could be allergic to these as well. The main reason is because they contain molds. The best way to avoid eating molds on nuts is to soak them in water for a few hours, then roast them in the oven.
The beef can cause too much ammonia production (gas) when compared to other meats, so I would stop this if possible. I eat chicken, lamb, turkey, and soon I want to try out buffalo!
