Evaluation of a short food frequency questionnaire used among Norwegian children.
2012
Objective: The aim of this study was to evaluate a short food frequency questionnaire (FFQ) against a four-day precoded food diary (PFD) with regard to frequency of food intake among Norwegian 9- and 13-year-olds. Subjects and design: A total of 733 9-year-olds and 904 13-year-olds completed first a short FFQ and one to two weeks later a four-day PFD. The short FFQ included questions about 23 food items, including different drinks, fruits, vegetables, bread, fish, pizza, sweets, chocolate and savoury snacks. The PFD covered the whole diet. Results: When comparing mean intake from the PFD with comparable food items in the FFQ, all food items showed that increasing intake measured with the PF…
Analysis of Fungicides in Fruits and Vegetables by Capillary Electrophoresis-Mass Spectrometry
2006
2014
Background : Social inequalities in health are a major and even growing problem in all European countries. Objective : The aim of the present study was to describe 1) differences in dietary habits among Norwegian adolescents by gender and socioeconomic status; 2) differences in self-reported knowledge of dietary guidelines among their parents according to socioeconomic status. Design : In 2012, a cross-sectional study where students filled in a web-based food frequency questionnaire at school was conducted in nine lower secondary schools in Vest-Agder County, Norway. Socioeconomic status (SES) and knowledge of dietary guidelines were obtained from the parents using a web-based questionnaire…
Introduction of a school fruit program is associated with reduced frequency of consumption of unhealthy snacks.
2012
Background: A diet high in fruit and vegetables (FV) is inversely related to chronic diseases, and some studies suggest that increasing the intake of FV reduces the intake of unhealthy snacks. Objectives: The objectives were to analyze changes in the frequency of consumption of unhealthy snacks (soda, candy, and potato chips) from 2001 to 2008 in Norwegian children, to assess whether being part of a school fruit program reduces the frequency of unhealthy snack consumption, and to explore differences in sex and socioeconomic status. Design: Within the project Fruits and Vegetables Make the Marks, 1488 sixth- and seventh-grade pupils from 27 Norwegian elementary schools completed a questionna…
Liberation and Micellarization of Carotenoids from Different Smoothies after Thermal and Ultrasound Treatments.
2019
The consumption of a varied diet rich in fruit and vegetables helps prevent and treat certain chronic diseases. The development of smoothies based on derivatives from fruit and vegetables rich in bioactive compounds can help increase the consumption of these foods, and therefore, contribute to the prevention of various health problems. However, during the processing of the fruit and vegetable smoothies, these properties may change. The elaboration of smoothies is based on fruits and vegetables rich in carotenoids: Carrot juice-papaya-mango (smoothie A) and carrot juice-pumpkin-mango (smoothie B). The objective of this study is to evaluate the impact of the application of different thermal t…
Dietary assessment methods in surveillance systems targeted to adolescents: A review of the literature
2019
Abstract Aims The present paper aims to identify ongoing multinational surveillance systems (SURSYSs) assessing diet and nutrition targeted to adolescents, including European surveys involving multiple countries and similar initiatives conducted in non-European countries with developed economies, and to describe the dietary assessment methods used. Data synthesis A total of 13 SURSYSs conducted in Europe, USA, Canada, Australia and New Zealand were identified. Dietary assessment methods commonly used include 24-h recalls (24H-Rs) and questionnaires or interviews. Food frequency questionnaires (FFQs) are used in combination with 24H-Rs in six SURSYSs: only FFQs are used in four SURSYSs; 24H-…
Changes in meal pattern among Norwegian children from 2001 to 2008
2011
AbstractObjectiveThe present study aimed to analyse changes in meal pattern among Norwegian children from 2001 to 2008 in general; to analyse associations between meal pattern and gender, parental educational level and number of parents in the household; and to analyse the association between intake of unhealthy snacks, meal pattern and the mentioned variables.DesignWithin the Fruits and Vegetables Make the Marks (FVMM) project, two cross-sectional studies were conducted, one in 2001 and one in 2008, where participants from the same schools filled in a questionnaire on meals eaten the previous day.SubjectsParticipants were 6th and 7th grade pupils, n 1488 in 2001 and n 1339 in 2008.SettingT…
Changes in beverage consumption in Norwegian children from 2001 to 2008
2011
AbstractObjectiveTo analyse (i) differences in beverage pattern among Norwegian children in 2001 and 2008; (ii) beverage intake related to gender, parental education and family composition; and (iii) potential disparities in time trends among the different groups.DesignWithin the Fruits and Vegetables Make the Marks (FVMM) project, 6th and 7th grade pupils filled in a questionnaire about frequency of beverage intake (times/week) in 2001 and 2008.SettingTwenty-seven elementary schools in two Norwegian counties.SubjectsIn 2001 a total of 1488 and in 2008 1339 pupils participated.ResultsBetween 2001 and 2008, a decreased consumption frequency of juice (from 3·6 to 3·4 times/week, P = 0·012), l…
Effect of the nationwide free school fruit scheme in Norway.
2010
In Norway, children and adolescents consume only about half of the national five-a-day recommendation. There are also rather large social inequalities in health, and in eating behaviours. In order to increase fruit and vegetable (FV) intake, a subscription programme was initiated in 1996 and made nationwide in 2003, and a free programme (without parental payment) has been implemented nationwide from 2007. The objective of the present study is to evaluate the effect of these efforts. Pupils in the sixth and seventh grades (age 10–12 years) at twenty-seven schools responded to a questionnaire in 2001 (n 1488, 85 %) and in 2008 (n 1339, 78 %). FV intake was measured by a 24-h recall. In 2001, …
Electron spin resonance as a tool to monitor the influence of novel processing technologies on food properties
2020
Abstract Background Nowadays, electron spin resonance (ESR) is widely used as a powerful, non-destructive and very sensitive technique for the detection of free radicals in food systems. It can be applied for the direct identification of highly reactive oxygen species, organic and inorganic paramagnetic species and screening of food for potential toxicity. Its applications cover investigating food oxidative stability and properties of irradiated foods including fruits and vegetables, meats and fishes, spices, cereal grains, and oil seeds. Scope and approach This review aims at providing specialists in food science and industry with the fundamentals of ESR spectroscopy, typical radicals pres…
