Measuring dietary fatty acid intake:validation of a food-frequency questionnaire against 7 d weighed records.
There are few validated methods of measuring dietary fatty acid intake that are suitable for epidemiological research. The purpose of the present study was to develop and validate a food-frequency questionnaire (FFQ) developed to measure individual dietary fatty acid intakes against 7 d weighed dietary records, in a sample of thirty-one healthy adult volunteers. The FFQ was based on a previousl...
متن کاملComparison between optical readable and open-ended weighed food records
BACKGROUND A simplified optically readable food record (ORFR) was developed and compared with an open-ended weighed record (WR). OBJECTIVE To compare intake of nutrients and foods using a seven-day ORFR with intake estimated using a seven-day WR. The results from each method were validated against 24-h urinary nitrogen excretion and energy intake (EI)/estimated basal metabolic rate (BMR) cut-...
متن کاملDiet-related greenhouse gas emissions assessed by a food frequency questionnaire and validated using 7-day weighed food records
BACKGROUND The current food system generates about 25 % of total greenhouse gas emissions (GHGE), including deforestation, and thereby substantially contributes to the warming of the earth's surface. To understand the association between food and nutrient intake and GHGE, we therefore need valid methods to assess diet-related GHGE in observational studies. METHODS Life cycle assessment (LCA) ...
متن کاملComparison of dietary assessment methods in nutritional epidemiology: weighed records v. 24 h recalls, food-frequency questionnaires and estimated-diet records.
Women (n 160) aged 50 to 65 years were asked to weigh their food for 4 d on four occasions over the period of 1 year, using the PETRA (Portable Electronic Tape Recorded Automatic) scales. Throughout the year, they were asked to complete seven other dietary assessment methods: a simple 24 h recall, a structured 24 h recall with portion size assessments using photographs, two food-frequency quest...
متن کاملEvaluation of energy and dietary intake estimates from a food frequency questionnaire using independent energy expenditure measurement and weighed food records
BACKGROUND We have developed a food frequency questionnaire (FFQ) for the assessment of habitual diet, with special focus on the intake of fruit, vegetables and other antioxidant-rich foods and beverages. The aim of the present study was to evaluate the relative validity of the intakes of energy, food and nutrients from the FFQ. METHODS Energy intake was evaluated against independent measures...
