Xerophagy
Xerophagy ("dry eating", from Greek ξηρός "dry" and φαγεῖν "eat") is a form of ancient Christian fasting in which a believer fasts from food and water until sunset, as well as abstains from meat, alcohol and succulent fruits for the one meal that is consumed after sunset; the early Church's Apostolic Constitutions enjoin for the meal eaten after sundown: bread, salt, water, nuts, as well as vegetables cooked with water and salt. The early Christian apologist Tertullian references this manner of fasting in his works.
