Potassium and protein are two components of foods that are essential for the human body. Potassium may help lower blood pressure and reduce the risk of heart attacks and strokes, according to Selene Yeager, author of "The Doctors Book of Food Remedies." Protein is an essential building block of organs and tissues, and provides consistent energy for your body and mind to function at optimal levels. Several foods, including some fruits, vegetables and beans, contain both potassium and protein.
