This evaluation aims to describe the quantity and quality of dietary fat, carbohydrate and fiber intake in both German cohorts participating in the European Prospective Investigation into Cancer and Nutrition (EPIC).
Estimates are based on standardized computer-guided 24-hour dietary recalls from 1,078 women and 1,013 men in Heidelberg and 898 women and 1,032 men in Potsdam. In a subsample, plasma phospholipid (PL) fatty acids were analyzed as well.
Adjusted mean dietary intake estimates demonstrated that the contribution of fat as well as n-6 and n-3 polyunsaturated fatty acids (PUFA) to the total daily energy intake was higher in both women and men of EPIC-Potsdam compared to EPIC-Heidelberg. Surprisingly, the dietary n-6/n-3 PUFA ratio was lower in the Potsdam cohort. These results were confirmed by means of the PL fatty acid pattern. Besides the higher contribution of polysaccharides to total energy intake in EPIC-Heidelberg, women of the Heidelberg cohort revealed a significantly lower contribution of mono- and disaccharides (sucrose) to total energy intake. Although total fiber intake data were similar in both cohorts, analysis by food groups showed differences in dietary fiber intake originating from the food groups cereals, fruits and potatoes.
The results demonstrate distinct differences in the dietary fat, carbohydrate and fiber intake between both German EPIC cohorts, which contribute to the exposure variation in the whole of EPIC.
本评估旨在描述参与欧洲癌症与营养前瞻性调查（EPIC）的两个德国队列中膳食脂肪、碳水化合物和纤维摄入的数量与质量。
评估基于海德堡1078名女性和1013名男性以及波茨坦898名女性和1032名男性的标准化计算机辅助24小时膳食回顾。在一个子样本中，还对血浆磷脂（PL）脂肪酸进行了分析。
调整后的平均膳食摄入量评估表明，与EPIC-海德堡队列相比，EPIC-波茨坦队列的男性和女性中，脂肪以及n-6和n-3多不饱和脂肪酸（PUFA）对每日总能量摄入的贡献更高。令人惊讶的是，波茨坦队列中的膳食n-6/n-3 PUFA比值更低。这些结果通过PL脂肪酸模式得到了证实。除了EPIC-海德堡队列中多糖对总能量摄入的贡献更高外，海德堡队列的女性单糖和双糖（蔗糖）对总能量摄入的贡献显著更低。尽管两个队列的总纤维摄入量数据相似，但按食物组分析显示，谷物、水果和土豆等食物组的膳食纤维摄入量存在差异。
结果表明，两个德国EPIC队列在膳食脂肪、碳水化合物和纤维摄入方面存在明显差异，这导致了整个EPIC研究中暴露情况的差异。
