Question 3

Compare and contrast incomplete and complete proteins.

Accepted Answer

A protein that does not contain all of the essential amino acids in sufficient quantities to support growth and health is called an incomplete (or low-quality) protein. Proteins that have all nine of the essential amino acids are considered complete (or high-quality) proteins. The most complete protein sources are from animal sources and include egg whites, ground beef, chicken, tuna and other fish, and milk. Soybeans are the only complete source of plant protein. In general, the Canadian diet is very high in complete proteins, as we eat proteins from a variety of food sources.
