肉假说声称，增加摄入肉类的营养改善人类饮食允许，在大脑和内脏和面部肌肉的萎缩增长的额外的蛋白质和氨基酸是关键。
膳食蛋白质的质量可以测量在许多方面作为时尚/谁1991的要求。但它主要是在食物或饮食中的氨基酸的比例相比，人类的基本需求。一个规模的S。我系统被用来作为比例的比例在命名。因此，百分之100或1的比例意味着饮食中的蛋白质的氨基酸存在于相同的量或多一点，比必要的氨基酸在体内只有一半是必要的。如果有人强制性的氨基酸是不存在的，一种情况可以发生实验分离蛋白作为任何食物，甚至不考虑整体的饮食，是由结合许多蛋白质；蛋白质的质量将是零（普兰，2008）。
肉制品是一种丰富的矿物质和维生素的来源。它们含有B族维生素包括核黄素、硫胺素、烟酸、维生素B12、B6、叶酸、生物素、泛酸。发现肝脏是Folacin和泛酸是人体肝脏的好。某些其他器官也在维生素A也给大量维生素K、D和E的意思是丰富的，也是一种矿物如铜、锌、铁、锰的来源，对锌是相当普遍缺乏回避的重要作用（Martin，2005）。
Meat hypothesis claims that increased intake of meat into the hominid diet allowed for improved nutrition and that the extra protein and amino acids were critical in the growth of the brain and the shrinking of guts and facial muscles.
Dietary protein’s quality may be measured in many ways as FAD/WHO 1991 requirements. But mostly it is a ratio of amino acids available in the food or diet as compared to human basic needs. A scale of S.I system is used as a percentage of ratios in the nomenclature. Therefore, a ratio of 100 per cent or 1.0 signifies that amino acids present in dietary proteins have exist in the same amount or a little more than the necessary amino acids present in the body is only half of what is needed. If anyone mandatory amino acid is not present, a situation that can take place experimentally with the isolated proteins as any food, not even considering the whole diet, is made up of a combination of many proteins; the quality of protein would be zilch (Pollan, 2008).
Meat products are a rich source of minerals and vitamins. They contain B-complex vitamins comprising of riboflavin, thiamine, niacin, vitamins B12 and B6, folacin, biotin, and pantothenic acid. Folacin and Pantothenic Acid are found in liver and are good for human liver. Certain other organs are also rich in vitamin A and also give huge amounts of vitamin K, D, and E. mean is also a source of minerals such as copper, zinc, iron, and manganese which paly an essential role in avoidance of deficiency of zinc which is quite widespread (Martin, 2005).
