> Animal protein is often refered to be "complete" and > plant protein as > "incomplete". This is misleading so far as all > proteins from plants contain > all of the essential amino acids. > Plants do not contain all of the non-essential amino > acids. I believe the "complete" vs. "incomplete" labels refer to whether a single food has all of the essential amino acids in proper proportions. Generally, A SINGLE animal food (meat, egg, etc.) DOES have all the essentials, while A SINGLE plant food does NOT. It is true that plants, in certain COMBINATIONS, CAN provide all of the essentials. I do not believe these labels address the non-essential amino acid issue at all.
