This has been borne out in the data: access to high quality animal fat and amino acids is absolutely critical to achieve maximum height. You can even observe it in fossils from the early Holocene, as agriculture expanded (hunter-gatherer diet was overwhelmingly meat dominant), human stature shrank: https://ourworldindata.org/grapher/human-heights-over-the-long-run https://ourworldindata.org/grapher/human-heights-over-the-lo... Only in late 19th/early 20th did European stature begin to return to natural levels from the Mesolithic. This effect was seen in American Indians, too. When early Europeans arrived in America, the Great Plains tribes were the tallest people in the world, due to game animal (bison, elk, deer, etc)-centric diet: https://www.sciencedaily.com/releases/2001/05/010529071125.htm https://www.sciencedaily.com/releases/2001/05/010529071125.h... https://www.westonaprice.org/health-topics/traditional-diets/guts-and-grease-the-diet-of-native-americans/ https://www.westonaprice.org/health-topics/traditional-diets...
