https://en.wikipedia.org/wiki/Protein_quality#Protein_sources https://en.wikipedia.org/wiki/Protein_quality#Protein_source... Lots of sources of complete protein on there besides beef. Don't limit yourself. A combination of quinoa, buckwheat, eggs, soy, pea, milk, whey, beans, and nuts will provide all the amino acids you need. Even beef, despite being a complete protein, is deficient in tryptophan. I like meat. I'm not a militant vegetarian or vegan or anything like that. I dislike the laundering of people's love of eating meat as "essential for health", when it's anything but (special dietary needs aside). Eating meat is a mostly a choice. I'll repeat again: varied diets are essential. A single protein source won't cut it. And most people get enough protein going just by raw numbers.
