BACKGROUND Improvement of traditional methods for dietary assessment is necessary, especially in rural areas where it is more difficult to succeed with self-reporting methods. This study presents and validates a method for improving accuracy when measuring food and nutrient intake of individuals in rural areas. It is called the "Food photography 24-h recall method" (FP 24-hR) and is a modified ...

Self-administered web-based 24-h dietary recalls (24 hR) may save a lot of time and money as compared with interviewer-administered telephone-based 24 hR interviews and may therefore be useful in large-scale studies. Within the Nutrition Questionnaires plus (NQplus) study, the web-based 24 hR tool Compl-eat™ was developed to assess Dutch participants' dietary intake. The aim of the present stud...

Food frequency questionnaire is an important assessment tool for public health nutrition research. We describe the development history and conducted the validity and reproducibility studies for a meal-based Chinese food frequency questionnaire (Chinese FFQ) by five meal sequences. A total of 51 subjects were recruited to collect dietary information twice (6 months apart) with one 24-hr recall, ...

fasting serum chromium, total cholesterol hdl-cholesterol, ldl-cholesterol, triacytglycerot and blood sugar were determined in fifty two diabetic patients with no other organic diseases anil compared with those obtained from a control group including fourty two healthy volunteers matched for age, sex ami body mass irutex (bmi). fasting serum chromium and hdl-cholesterol were significantly lower...

BACKGROUND Few studies have evaluated the linkage between food cost and mortality among older adults. This study considers the hypothesis that greater food expenditure in general, and particularly on more nutritious plant and animal-derived foods, decreases mortality in older adults. METHODS This study uses the 1999-2000 Elderly Nutrition and Health Survey in Taiwan and follows the cohort unt...

Two nitro-substituted 1,4-distyrylbenzene-like compounds have been investigated using stationary and time-resolved (ns/fs) spectrometric techniques as a function of solvent polarity. In the two compounds the central benzene ring is substituted with a p-nitrostyryl group at one side while, at the other side, compound 1 (asymmetric) bears a pyrid-4-ylethenyl group and compound 2 (symmetric) anoth...

Background: Misreporting, recalling and overestimation are common problems with dietary assessment methods currently available. The 7-day weighed food record (7DWR) method involves an individual weighing of each and every food item prior to consumption, and is considered as a reference method in many situations. The present study aims to compare the energy and nutrient intakes, estimated from 7...

Online dietary assessment tools offer a convenient, low cost alternative to traditional dietary assessment methods such as weighed records and face-to-face interviewer-led 24-h recalls. INTAKE24 is an online multiple pass 24-h recall tool developed for use with 11-24 year-old. The aim of the study was to undertake a comparison of INTAKE24 (the test method) with interviewer-led multiple pass 24-...

OBJECTIVE To evaluate the relationship between the behaviors of salt consumption and socio-demographic and clinical variables. METHOD Sodium consumption was evaluated using the methods: self-reporting (considering 3 different behaviors related to salt consumption), 24- hr dietary recall, discretionary salt, food frequency questionnaire, estimation of total sodium intake and 24-hr urinary excr...
