Old English foda "food, nourishment; fuel," also figurative, from Proto-Germanic *fodon (cf. Gothic fodeins), from Germanic root *fod-, equivalent of PIE *pa- "to tend, keep, pasture, to protect, to guard, to feed" (cf. Greek pateisthai "to feed;" Latin pabulum "food, fodder," panis "bread," pasci "to feed," pascare "to graze, pasture, feed," pastor "shepherd," literally "feeder;" Avestan pitu- "food;" Old Church Slavonic pasti "feed cattle, pasture;" Russian pishcha "food").
Food chain is from 1917. Food poisoning attested by 1864; food processor in the kitchen appliance sense from 1973.
Material, usually of plant or animal origin, that contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals, and is ingested and assimilated by an organism to produce energy, stimulate growth, and maintain life.
Originally the Creator granted the use of the vegetable world for food to man (Gen. 1:29), with the exception mentioned (2:17). The use of animal food was probably not unknown to the antediluvians. There is, however, a distinct law on the subject given to Noah after the Deluge (Gen. 9:2-5). Various articles of food used in the patriarchal age are mentioned in Gen. 18:6-8; 25:34; 27:3, 4; 43:11. Regarding the food of the Israelites in Egypt, see Ex. 16:3; Num. 11:5. In the wilderness their ordinary food was miraculously supplied in the manna. They had also quails (Ex. 16:11-13; Num. 11:31). In the law of Moses there are special regulations as to the animals to be used for food (Lev. 11; Deut. 14:3-21). The Jews were also forbidden to use as food anything that had been consecrated to idols (Ex. 34:15), or animals that had died of disease or had been torn by wild beasts (Ex. 22:31; Lev. 22:8). (See also for other restrictions Ex. 23:19; 29:13-22; Lev. 3:4-9; 9:18, 19; 22:8; Deut. 14:21.) But beyond these restrictions they had a large grant from God (Deut. 14:26; 32:13, 14). Food was prepared for use in various ways. The cereals were sometimes eaten without any preparation (Lev. 23:14; Deut. 23:25; 2 Kings 4:42). Vegetables were cooked by boiling (Gen. 25:30, 34; 2 Kings 4:38, 39), and thus also other articles of food were prepared for use (Gen. 27:4; Prov. 23:3; Ezek. 24:10; Luke 24:42; John 21:9). Food was also prepared by roasting (Ex. 12:8; Lev. 2:14). (See COOK.)
