She recommends avoiding pork, since pork tends to be more susceptible to parasites. Organ meats are also a good choice, but use caution when feeding liver. If you feed liver, make sure it's from a clean, preferably organic, source. After choosing the protein source, add vegetables. Dark green veggies and carrots are excellent choices.

Be sure to wash them to remove pesticides, dirt and other junk - if organic produce is too expensive or unavailable in your area, invest in a good produce wash like Healthy Harvest to get the surface pesticides off. Occasionally feeding eggs or small amounts of dairy products like yogurt and cottage cheese is OK too. If you decide to feed grains, brown rice, oatmeal and barley are healthy and inexpensive. Pollack doesn't recommend supplements in general, but they can be used for specific medical situations. Supplements can be expensive and are themselves processed - it's easier to get Vitamin C from an orange than a pill.
