Avoid breaded, fried foods; try to avoid the prepared foods aisles in the grocery store, i.e., buy mostly fresh fruits, veggies, meats and seasonings such as ginger and garlic, and prepare simple meals using those ingredients with spices and lots of fresh herbs.
Instead of white bread, pasta and rice, try whole wheat bread and pasta and brown rice. HTH.
Anyplace where people argue about food is a good place.
