You et al. shows that meat intake is positively associated with life expectancy at national level; the underlying reasons may be that meat not only provides energy but also complete nutrients to human body; from the evolutionary point of view, meat has arguably been an indispensable component in human diet for millions of years, which is evidenced, genetically, by meat digesting enzymes and digestive tract anatomy; the complete nutritional profile of meat and human adaptation to meat eating have enabled humans to gain many physical benefits, including greater life expectancy; meat intake, or its adequate replacement, should be incorporated into nutritional science to improve human life expectancy.
