OBJECTIVE Adjustment for body weight and physical activity has been suggested as an alternative to adjusting for reported energy intake in nutritional epidemiology. We examined which of these approaches would yield stronger correlations between nutrients and their biomarkers. DESIGN A cross-sectional study in which dietary fatty acids, carotenoids and retinol were adjusted for reported energy...

there are many potential risks to human health from heavy metal contamination of vegetables resulting from wastewater irrigated sites. this study was carried out to assess the concentration of chromium (cr) and the risk to human health by chromium through the intake of locally grown vegetables collected from wastewater irrigated agricultural fields. twenty-seven samples of 9 (nine) different ty...

BACKGROUND We examined the effect of seasonality on the validity (ability to estimate the mean intake of a group and ranking ability) of nutrient intakes estimated with a comprehensive self-administered diet history questionnaire (DHQ) developed for the assessment of Japanese diets during the preceding one month, using semi-weighed dietary records (DRs) as a reference method. METHODS This stu...

OBJECTIVE To examine the effect of fast-food and full-service restaurant consumption on adults' energy intake and dietary indicators. DESIGN Individual-level fixed-effects regression model estimation based on two different days of dietary intake data was used. SETTING Parallel to the rising obesity epidemic in the USA, there has been a marked upward trend in total energy intake derived from...

BACKGROUND Anorexia of ageing may predispose older adults to under-nutrition and protein energy malnutrition. Studies, however, report a large variation in nutrient inadequacies among community-dwelling older adults. SUMMARY This systematic review provides a comprehensive overview of the energy and macronutrient intakes and possible inadequacies in community-dwelling older adults. PubMed and ...

Background: The present study was carried out to develop and validate an analytical method for the detection and quantification of lambda-cyhalothrin, a synthetic pyrethroid insecticide, in tomato using gas chromatographyelectron capture detector (GC-ECD). The study has meant to ascertain lambda-cyhalothrin dissipation behavior under dry land conditions. Results: The analytical method was valid...

Chlormequat is a commonly used plant growth regulator in agriculture. Defined levels of chlormequat residue are allowed in food and an acceptable daily intake is defined for humans. However, there are results in the literature suggesting that a daily intake below the acceptable level for human is detrimental for mammalian reproduction. In the present experiment we investigated the effect of chl...

OBJECTIVES To determine the criterion validity and user acceptability of the Healthy Eating Self-Monitoring Tool (HEST), a CD-ROM-mediated food record for measuring fruit and vegetable consumption among economically disadvantaged black adolescents. DESIGN Item intakes, daily intake measures of fruit, vegetables and juices, and daily and total fruit and vegetable intake assessed with the HEST ...
