Is protein from meat "better" than protein you get from other sources?

Proteins are made of chains of amino acids. If you take apart the protein, you get a certain amount of each amino acid. Meat/dairy is more "efficient", because the ratios of the different acids are the same from one animal to another. Plants will usually be short on one or two amino acids, so you don't effectively get as much protein as it says on the label.

You just need to have more than one kind of grain/nut/legume in your diet, which you probably have already, unless you're a farmer going through hard times in 1400.
