We examined the validity and the problem of the photographic dietary assessment for the purpose of nutritional education for children. Twenty-six meals were evaluated both traditional weighed dietary records and photographic assessment. For the photo method, two dieticians independently identified foods and quantities from the meal photographs in twice. The first estimation was performed on the basis of only photographs and some information concerned with cooking were added to the second estimation. The correlation coefficient between traditional weighed dietary records and photographic assessment varied from 0.523 (salt) to 0.985 (vitamin C) in the first estimation and from 0.710 (carbohydrate) to 0.997 (vitamin D) in the second. The correlation of variation ranged from 21.3% (vitamin B2) to 48.0% (vitamin D) in the first and from 13.8% (total energy) to 38.7% (vitamin A) in the second. The correlation coefficient between observers varied from 0.679 (salt) to 0.943 (vitamin D). The photographic dietary assessment was generally acceptable with a hearing report about cooking materials and methods.
