Assessment of the intake of dietary fibre from cereal foods: an epidemiological approach.

Abstract

In a study evaluating the intake of dietary fiber from cereal foods, the results obtained from a standard 7 day weighed record were compared with simpler methods. This showed that weighing was unnecessary to obtain a valid measure of intake. There was also a low ratio of within-subject to between-subject variation: thus 4 days of recording are all that are required. The 4 day unweighed record is cheaper, less complex and may produce higher completion rates than the 7 day weighed record.
