Twenty-four-hour dietary recalls can provide high-quality dietary intake data, but are considered expensive, as they rely on trained professionals for both their administration and coding. The objective of this study was to develop an automated, self-administered web-based 24-h recall (R24W) for a French-Canadian population. The development of R24W was inspired by the United States Department o...

This study assesses the operational feasibility and validity of a unique telephone-administered 24-h dietary recall methodology. Dietary interviews were conducted by telephone with 204 low-income elderly subjects. Food portion size estimation was done using a two-dimensional food portion visual aid the that was mailed to respondents' homes. The mean intakes and distributions of nine nutrients a...

BACKGROUND/OBJECTIVES The Recaller app was developed to help individuals record their food intakes. This pilot study evaluated the usability of this new food picture application (app), which operates on a smartphone with an embedded camera and Internet capability. SUBJECTS/METHODS Adults aged 19 to 28 years (23 males and 22 females) were assigned to use the Recaller app on six designated, non...

Diet, along with lifestyle factors, is an important determinant of the health status of an individual and of a community. Dietary assessment at the population level provides us with key information on the frequency and distribution of possible inadequate diets and/or nutritional status. It is also useful as input into the elaboration of food and nutrition policies aiming to improve dietary habi...

This report presents dietary intake estimates for selected minerals from the National Health and Nutrition Examination Survey, 1999-2000, for the U.S. population. These minerals included: calcium, copper, iron, magnesium, phosphorus, potassium, selenium, sodium, and zinc. Mineral intakes are estimated from one 24-hour dietary recall interview. Population means, medians, and standard errors of t...

In the United States the preferred method of obtaining dietary intake data is the 24-hour dietary recall, yet the measure of most interest is usual or long-term average daily intake, which is impossible to measure. Thus, usual dietary intake is assessed with considerable measurement error. Also, diet represents numerous foods, nutrients and other components, each of which have distinctive attri...

The quest to improve dietary intake assessment and to achieve more accurate estimates of average daily consumption is ongoing. The primary dietary assessment method used in the National Health and Nutrition Examination Survey, conducted by the United States Center for Disease Control and Prevention, is the 24-hour recall of dietary intake (Moshfegh et al., 2008). Unfortunately, although this me...
