改进的食物成分数据对营养摄入估计的影响是通过重新分析来自个人食物摄入持续调查（CSFII） 1994-1096, 1998和多年版本的饮食研究食物和营养数据库（FNDDS） 1.0的膳食摄入数据来确定的，其中只有数据的改进，如那些由于新的分析数据取代了旧的值。确定了旧估计值和修正估计值之间的平均差异。改进后的数据导致大多数营养素的平均摄入量估计值存在微小但具有统计学意义（P = 0.001）的差异。差异最大的营养物质或食物成分包括维生素C、核黄素、镁和咖啡因。由于这些变化，4-7%的成年人维生素C和镁摄入量不足。咖啡因的摄入量降低了约25%。液态牛奶、西红柿、咖啡和混合菜肴的食物成分值的变化似乎影响最大。这些人为的变化需要对早期摄入量估计进行调整，以提高与当前摄入量的可比性。(c) 2006爱思唯尔公司版权所有。
The effect of improved food composition data on nutrient intake estimates was determined by re-analyzing dietary intake data from the Continuing Survey of Food Intake by Individuals (CSFII) 1994-1096, 1998 with the multi-year version of the Food and Nutrient Database for Dietary Studies (FNDDS) 1.0, wherein only the data improvements such as those due to new analytical data replaced the older values. Mean differences between the old and revised estimates were determined. Improved data resulted in minor but statistically significant (P = 0.001) differences in mean intake estimates for most nutrients. Nutrients or food components with greatest differences included vitamin C, riboflavin, magnesium, and caffeine. As a result of these changes, 4-7% more adults have inadequate intakes of vitamin C and magnesium. Caffeine intakes were lower by about 25%. Changes in the food composition values for fluid milk, tomatoes, coffee, and mixed dishes appear to have had the most impact. These artifactual changes require adjustments to the earlier intake estimates to improve comparability with more current intakes. (c) 2006 Elsevier Inc. All rights reserved.
