Where can I find a complete list of protein foods that I can eat?

You can get advice on this from yourdietitianand local health organization sites. Soy beans, peanuts, meats and fish are all good sources of proteins.

Note that all unrefined foods contain protein. Determining which foods are "high" in protein depends on how you measure it. Kale, for example, contains 6.6 grams of protein in a 100-calorie serving, whereas a 100-calorie serving of ground beef has 4.3 grams of protein.
