W. Warde Fowler, Social life at Rome in the Age of Cicero
“ The ancients were fully alive to the value of vegetable food and of fruit as a healthy diet in warm climates, and the wonderfully full information we have on this subject comes from medical writers like Galen, as well as from Pliny's Natural History, and from the writers on agriculture. The very names of some Roman families, e.g. the Fabii and Caepiones, carry us back to a time when beans and onions, which later on were not so much in favour, were a regular part of the diet of the Roman people. ”
