Dietary question (allergy/sinus related, see details)

I just went for acupuncture for the first time to hopefully alleviate my allergy issues and she said that I am extremely congested. She could tell that I had poor circulation in my upper body by looking at my tongue, and also could feel in my face that everything is very “full.” Her suggestion to me was to change my diet – cut out pasta, pizza, cow dairy products (goat cheese is fine though), orange juice and tomato sauce because of the sugar, etc…

The problem is that these are things I eat all the time! She basically told me I can eat meat, veggies, and brown rice.

So, hoping that this will help me be able to breathe (and maybe drop a few pounds too), I am going to try it!

What do you suggest I cook at home? Order in? I am uncomfortable cooking meat (it just isn’t my thing and always comes out dry) and I’m highly addicted to flavor and condiments.
Any inexpensive, easy recipes or ideas would be great!
