Fish and marine resources are a primary food source. Only the most hardy plants can grow there. Local crops include coconut, giant swamp taro, breadfruit, pandanus, and a native fig. Coconut is central to the diet and is especially valued for the sweet rich toddy (sap) cut from the flower spathe. Toddy is used as a children’s drink or as a base for syrup. It can also be soured into vinegar and fermented into an alcoholic drink. Drunkenness is a widespread problem that is dealt with on some islands by the prohibition of alcohol. Imported goods such as rice, flour, canned butter, and canned fish and meat, are becoming increasingly important in the daily diet.
