I am reading Charles Darwin recounting of his travel on the Beagle, and in Argentina he mentions the Gaucho diet that is essentially only eating beef and drinking mate.

From wikipedia [0]

>The gaucho diet was composed almost entirely of beef while on the range, supplemented by yerba mate (erva-mate in Portuguese), an herbal infusion made from the leaves of a South American tree, a type of holly rich in caffeine and nutrients.
