Passage　2

The　food　we　eat　seems　to　have　profound　effects　on　our　health.　Although　science　has　made　enormous　steps　inmaking　food　more　fit　to　eat,it　has,at　the　same　time,made　many　foods　unfit　to　eat.Some　research　has　shown　that　perhaps　eighty　percent　of　all　human　illnesses　are　related　to　diet　and　forty　percent　of　cancer　is　related　to　the　diet　as　well,especially　cancer　of　the　colon.Difficult　cultures　are　some　prone　to　contract　certain　illnesses　because　of　the　food　that　is　characteristic　in　these　cultures.That　food　is　related　to　illness　is　not　a　new　discovery.In　1945,government　researchers　realized　that　nitrates　and　nitrites,commonly　used　to　preserve　color　in　meats,and　other　food　additives,caused　cancer.Yet,these　carcinogenic　additives　remain　in　our　food,and　it　becomes　more　difficult　all　the　time　to　know　which　things　on　the　packaging　labels　of　processed　food　are　helpful　or　harmful.The　additives　which　we　eat　are　not　all　so　direct.Farmers　often　give　penicillin　to　beef　and　poultry　and　because　of　this,penicillin　has　been　found　in　the　milk　of　treated　cows.Sometimes　similar　drugs　are　administered(given)　to　animals　not　for　medicinal　purposes,　but　for　financial　reasons.The　farmers　are　simply　trying　to　fatten　the　animals　in　order　to　obtain　a　higher　price　on　the　market.Although　the　Food　and　Drug　Administration　has　tried　repeatedly　to　control　these　procedures,the　practices　continue.
