| 抄録 | 本研究採用化學分析法與計算法分別評量雜食與素食飲食之總鐵含量,以比較兩種方法之差異;並採用計算法根據兩種飲食之血原素與非血原素鐵含量,和肉類與維生素C之供應量，以估計其鐵質之生體可用量. 雜食與素食飲食乃分別收自台北國防醫學院與中壢圓光佛學院之學生餐廳. 飲食評估共執行兩次,每次連續三天,對每天早，中，晚餐每道菜餚之供應量以稱重法記錄,並且蒐集樣品,經冷凍乾燥與磨碎後供化學分析測定其營養組成. 飲食之鐵含量分別以食品組成分表估算與耦合電漿激發光譜儀分析定量,以為比較. 所得鐵含量之計算值是雜食19. 8mg/day，素食17. 5mg/day ;分析值是雜食16. 1mg/day，素食11. 6mg/day. 含鐵密度之計算值每1000大卡為雜食7. 7mg，素食7. 5mg;分析值則為雜食6. 2mg，素食5. 0mg. 兩種飲食中鐵的形式均以非血原素鐵為主. 化學分析法與計算法所得之結果有顯著的相關性. 不過,對素食飲食而言,分析值顯著低於計算值. 可利用之鐵量在雜食組為0. 65mg/1000kcal;素食組若含維生素C效應時為0. 39mg/1000kcal,若不含維生素C效應時為 0. 22mg/1000kcal,分別佔總鐵供應量之8. 4%，5. 3%與 3. 0%. 素食飲食之含鐵密度與鐵質生體可用率均較低,可能無法滿足生育年齡之女性之需要. The iron content in vegetarian and omnivorous diets was quantified by both chemical analysis and by calculation from food composition tables. The bioavailability of iron from these diets was estimated on a meal basis of the amount of heme iron，non-heme iron and enhancing factors including ascorbic acid，meat，fish and poultry. Foods from vegetarian and omnivorous diets were collected from the student dining service in Yuan-Guan Buddhist College，Chungli，and the National Defense Medical School，Taipei，respectively. Three servings of every dish provided at breakfast，lunch and dinner were collected，weighed，combined，freeze-dried，ground up，and used for chemical analysis. By calculation，the iron supply averaged 19. 8mg/day and 17. 5mg/day，and the iron density was 7. 7 and 7. 5mg/1000kcal，in omnivorous and vegetarian diets, respectively. By chemical analysis, the iron supply was 16. 1 and 11. 6mg/day，and the iron density was 6. 2 and 5. 0mg/1000kcal in omnivorous and vegetarian diets, respectively. Non-heme iron was the major dietary iron form. Correlation between calculated and analyzed values was significant for both types of diets, but in the vegetarian diets, the analyzed value was significantly less than the calculated value. Estimated amount of bioavailable iron was 0. 65mg/1000kcal from the omnivorous diets, and it was 0. 39 and 0. 22mg/day in the vegetarian diets with or without the vitamin C effect，respectively. The estimated bioavailability was 8. 4% in the omnivorous diet，and it was 5. 3% and 3. 0% in the vegetarian diets with and without the vitamin C effect，respectively. The vegetarian diets were low in both iron content and availability，and may not provide adequate iron for women of child-bearing age. |
