Protein isolate powder has more protein than red meat, so you should be eating that, not meat, by this measure. * The density of protein is not important at all. What is important is that you get the sufficient daily amount of protein, which is easily achievable by eating plant-based foods only. * It is a myth that the "amino acid spectrum" is not always complete. Plants contain all essential amino acids, and as long as you aren't on a strict white-rice diet, you'll get everything you need from a modest variety of foods. Please stop spreading misinformation.
