First of Fat-Fighter8 lists eight essential amino acids. The usual culprits list nine (http://www.nlm.nih.gov/medlineplus/ency/a
rticle/002222.htm). Missing from Fat-Fighter8's list is histidine. I've seen at least one claim that there are eight essential amino acids, but that source (I no longer remember where I saw it) explicitly stated that methionine is not as critical as commonly thought rather than blithely listing eight and apparently not noticing that one was missing. I also have to love this opening sentence on the page FF8 linked to: "Protein is a chain of different amino acids." No, protein is a generic term for certain structural components of a living organism. A singular protein, please note the article "a," is a chain of assorted amino acids, but there's lots of different proteins, each serving a different function.
It should be noted that since proteins are necessary structural components of organisms, in addition to various other functions, all whole foods contain some protein. It's just that some foods have higher concentrations than others. Flowering plants tend to put the highest protein concentrations in their seeds (nuts, legumes, and grains are all seeds) to provide structural components necessary to the development of the next generation. The protein in eggs serves the same function for oviparous animals.
