The Finnish national food composition database Fineli was updated with recent analytical values for plant sterols (PS) (sitosterol, campesterol, stigmasterol, avenasterol, brassicasterols and stanols) and cholesterol. The quality of the new analytical data was assessed. The aims of the present study were: (1) to compare the effect of old and new database values on PS and cholesterol intakes based on average per capita food consumption data; (2) to estimate the current intake and major sources of these compounds in various population groups according to the national FINDIET 1997 survey data. The intake of total PS was 305 mg/d for men and 237 mg/d for women. The respective intakes for cholesterol were 284 mg/d and 201 mg/d. Women had a higher density of PS in their diets than men, whereas the cholesterol density in the diets did not differ between genders. Cereals, margarine, vegetables and vegetable oils were the main food sources of PS. Meat, meat products and eggs were the main sources of cholesterol. A 9 % greater PS intake estimate was obtained with the new PS database compared with the old PS database, probably due to minor methodological differences between the new and old analyses. Notable changes in analytical methods suggest a lower value (-19 %) for cholesterol intake calculated from the new database compared with the old one. We conclude that researchers can have confidence in the new values for PS and cholesterol, because systematic evaluation of the new analytical values showed them to be of high quality.
芬兰国家食品成分数据库Fineli更新了植物甾醇(PS)(包括谷甾醇、菜油甾醇、豆甾醇、燕麦甾醇、油菜甾醇和甾烷醇)和胆固醇的最新分析值。对新分析数据的质量进行了评估。本研究的目的是:(1)根据人均食物消费数据,比较新旧数据库值对PS和胆固醇摄入量的影响;(2)根据1997年全国FINDIET调查数据,估计不同人群中这些化合物的当前摄入量及其主要来源。男性的总PS摄入量为305毫克/天,女性为237毫克/天。胆固醇的相应摄入量分别为284毫克/天和201毫克/天。女性饮食中PS的密度高于男性,而饮食中胆固醇的密度在性别之间没有差异。谷物、人造黄油、蔬菜和植物油是PS的主要食物来源。肉类、肉制品和蛋类是胆固醇的主要来源。与旧的PS数据库相比,新的PS数据库得出的PS摄入量估计值高9%,这可能是由于新旧分析方法存在细微差异。分析方法的显著变化表明,与旧数据库相比,新数据库计算出的胆固醇摄入量值较低(-19%)。我们得出结论,研究人员可以信赖PS和胆固醇的新值,因为对新分析值的系统评估表明它们具有很高的质量。
