A single bunch of date palms that weighs about 8 kg may contain as many as 1000 dates. “The dried fruit is more than 50% sugar by weight and contains about 2% each of protein, fat and mineral water” (online-family-doctor.com, n.d.).

Another proof of the antiquity of this fruit is the Nile Valley in Egypt where the date palm was adopted to symbolize a year in the Egyptian hieroglyphics whereas the frond of the date palm was used as a month’s symbol. “[This information] is confirmed by history, and corroborated by the archaeological research into ancient historical remains of the Sumerians, Akadians and Babylonians…Houses of these very ancient people were roofed with palm tree trunks and fronds. The uses of date for medicinal purposes, in addition to its food value, were also documented” (Zaid and Wet, n.d.). Date palms are believed to originate in Babel, Iraq, though there are also evidences of its origination in Harqan, and Dareen.
