Purseglove (1968), In his authoritative textbook, labeled the avocado "...the most nutritious of all fruits." Noted food writer Gaylord Hauser once said of it: "In this single delectable fruit are combined the protein of meat, the fat of butter [but much more wholesome!], the vitamins and minerals of green vegetables, the flavor of nuts, a six course dinner ". America's greatest plant explorer, David Fairchild is attributed "...the avocado is a food without rival among the fruits, the veritable fruit of paradise." And in 1959, cereal pioneer John H. Kellogg maintained that "of all edible fruits, it stands pre-eminent as a source of concentrated nutriment adapted to human use. For purity, wholesomeness, ease of digestibility, and adaptation to human needs, it has few rivals and none that can fill its place." (Quotation courtesy of J. S. Shepherd).
