Complete protein foods are those which contain all eight essential amino acids. Eggs, dairy products, and meats are all complete proteins. Non-animal complete protein sources are soybeans and brown rice.
Foods which contain incomplete proteins can usually be combined with each other in a tasty
manner, thus completing each other. For instance, grain
s and legume
s complement one another. Complete proteins such as dairy products can also be used to increase the quality of the incomplete protein in grains, as in macaroni and cheese
, milk and Wheaties
, grilled cheese sandwich
