Protein can be supplied from animal food sources, such as lean meat, poultry, fish, eggs, milk, and cheese, or vegetable food sources such as dried beans and peas, peanut butter, nuts, seeds, and tofu.

Vegetable protein sources, in combination, can complement one another to provide a high-quality protein.
Protein is an important part of wellness and nutrition.
