To investigate the intake of plant sterols and identify major dietary sources of plant sterols in the British diet.
A total of 24 798 men and women recruited during 1993-1997, participating in the European Prospective Investigation into Cancer (EPIC-Norfolk).
A database of the plant sterol (campesterol, beta-sitosterol, stigmasterol, campestanol and beta-sitostanol) content in foods, based on gas-liquid chromatography (GLC) analyses, was linked to nutritional intake data from food frequency questionnaires in the EPIC-Norfolk population.
The mean (s.d.) intake of total plant sterols was 300 (108) mg/d for men and 293 (100) mg/d for women. Bread and other cereals, vegetables and added fats were the three major food sources of plant sterols representing 18.6 (8.9), 18.4 (8.5) and 17.3 (10.4)% of the total plant sterol intake respectively. Women had a higher plant sterol density than men (36.4 vs 32.8 mg/1000 kJ, P<0.001) and in relation to energy intake higher intakes of plant sterols from vegetables, bread and other cereals, added fats, fruits and mixed dishes (all P<0.001), whilst men had higher intakes of plant sterols from cakes, scones and chocolate, potatoes (all P<0.001) and other foods (P<0.01).
The intake of plant sterols in UK, mainly from bread, cereals, fats and vegetables, is much higher than previously reported but comparable to recent European studies.
调查英国饮食中植物甾醇的摄入量，并确定植物甾醇的主要膳食来源。
1993年至1997年招募的总共24798名男性和女性，参与欧洲癌症前瞻性调查（EPIC-诺福克）。
基于气液色谱（GLC）分析的食物中植物甾醇（菜油甾醇、β-谷甾醇、豆甾醇、菜子甾醇和β-谷甾烷醇）含量数据库，与EPIC-诺福克人群食物频率问卷中的营养摄入数据相关联。
男性总植物甾醇的平均（标准差）摄入量为300（108）mg/天，女性为293（100）mg/天。面包和其他谷物、蔬菜以及添加脂肪是植物甾醇的三大主要食物来源，分别占植物甾醇总摄入量的18.6（8.9）%、18.4（8.5）%和17.3（10.4）%。女性的植物甾醇密度高于男性（36.4对32.8 mg/1000 kJ，P<0.001），就能量摄入而言，来自蔬菜、面包和其他谷物、添加脂肪、水果和混合菜肴的植物甾醇摄入量更高（均P<0.001），而男性从蛋糕、烤饼和巧克力、土豆（均P<0.001）及其他食物中摄入的植物甾醇更多（P<0.01）。
英国植物甾醇的摄入量主要来自面包、谷物、脂肪和蔬菜，远高于此前报道，但与近期欧洲研究结果相当。
