Assessment of the intake of dietary fibre from cereal foods: an epidemiological approach.
  1. A J Silman

    Abstract

    In a study evaluating the intake of dietary fibre 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 four days of recording are all that are required. The 4-day unweighed record is cheaper, less complex, and may be expected to produce higher completion rates than the 7-day weighed record.
