Comparison of food consumption and nutrient intake assessed with three dietary assessment methods: results of the German National Nutrition Survey II

Abstract

Purpose Comparison of food consumption, nutrient intake and underreporting of diet history interviews, 24-h recalls and weighed food records to gain further insight into specific strength and limitations of each method and to support the choice of the adequate dietary assessment method. Methods For 677 participants (14-80 years) of the German National Nutrition Survey II confidence intervals for food consumption and nutrient intake were calculated on basis of bootstrapping samples, Cohen's d for the relevance of differences, and intraclass correlation coefficients for the degree of agreement of dietary assessment methods. Low energy reporters were identified with Goldberg cut-offs. Results In 7 of 18 food groups diet history interviews showed higher consumption means than 24-h recalls and weighed food records. Especially mean values of food groups perceived as socially desirable, such as fruit and vegetables, were highest for diet history interviews. For "raw" and "cooked vegetables", the diet history interviews showed a mean consumption of 144 and 109 g/day in comparison with 68 and 70 g/day in 24-h recalls and 76 and 75 g/day in weighed food records, respectively. For "fruit", diet history interviews showed a mean consumption of 256 g/day in comparison with 164 g/day in 24-h recalls and 147 g/day in weighed food records. No major differences regarding underreporting of energy intake were found between dietary assessment methods. Conclusions With regard to estimating food consumption and nutrient intake, 24-h recalls and weighed food records showed smaller differences and better agreement than pairwise comparisons with diet history interviews.

A Web-Based 24-H Dietary Recall Could Be a Valid Tool for the Indicative Assessment of Dietary Intake in Older Adults Living in Slovenia

“…Looking at the estimates of dietary intakes obtained by both methods, some differences can be found. In general, both methods provided, to some extent, results comparable to other studies [16,17,43,44]. The mean dietary intakes obtained with the web-based 24HDR significantly correlate with those obtained with the WFR method.…”

Red meat (beef and sheep) products for an ageing population: a review

“…Furthermore, the German National Nutrition Survey II used interviews of diet history to show that older people consumed less meat than younger adults – although here meat referred to all meat types except for fish (Heuer et al , ). It is worth noting that interviews of diet history were found to corroborate other dietary assessment methods within this same previous survey (Straβburg et al , ). While the increased worldwide population is expected to compensate for these trends and supports an annual projected increase in beef and lamb consumption – with most of the gains expected within Asian, African, South American and Oceanian markets (FAO, ) – it would be prudent to consider the demands and requirements of red meat products from elderly people.…”

Brain nutrients: Cerebral metabolism and micronutrients

“…The results of the National Consumption Survey II showed that the daily vitamin D intake of > 96% of girls and 86% of boys aged 14-18 years failed to meet the recommendations [9,10]. A recent European study, which collected data on the 25(OH)D status of 1006 adolescents aged between 12.5 and 17.5 years, showed that 39% of them had an inadequate vitamin D status (25(OH)D: 20-30 ng/mL), 27% a vitamin D deficiency, and 15% a severe vitamin D deficiency.…”

“…Worldwide, iron deficiency is by far the most common trace element deficiency. In Europe, the prevalence of iron deficiency is about 10% [10]. Iron deficiency may have a negative impact on cognitive function in children.…”
