Bioaccessibility of bioactive compounds from fruits and vegetables after thermal and nonthermal processing

2017

Abstract Background The growing demand for nutritious, healthy, and still attractive foods drives the future of food processing to be multipurpose and more sophisticated. Information and insight of the relation between thermal and nonthermal treatments (high pressure processing, high pressure homogenization, pulsed electric fields, etc.) with bioaccessibility of phytochemicals is important not only for researchers, but also for the food industry, thus giving opportunities to develop innovative healthy food products. Scope and approach The food industry finds it crucial to develop processing technologies, which at the same time will preserve and improve the nutritive value of foods and make …

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…

Assessment of the microbiological quality of fresh produce on sale in Sicily, Italy: preliminary results

2015

Background Fresh produce occupies an increasingly important place in the human food supply because of its health-promoting nutritional properties. Most fresh produce is eaten raw or after minimal processing and, consequently, pathogen contamination can represent a serious health risk. There has been an increase in foodborne outbreaks and cases associated with fresh produce, but literature data about the prevalence of pathogen contamination are inconsistent. This study was undertaken to assess the hygienic quality and the prevalence of the most common bacterial pathogens in fresh produce sold in retail markets in Sicily. A total of 125 samples of different types of vegetables were examined b…

Effect of Hot Air Treatment on Quality and Shelf Life of Minimally Processed Cauliflower.

2012

Cauliflower, as other cabbages, has a high nutritional value due to its content of vitamins, antioxidants and anti-carcinogenic compounds. Cauliflower inflorescences are harvested when they are still totally immature. The request of minimally processed vegetable is continuously increasing, and there is a growing interest for new fresh cut products. Cauliflower is suitable to be used as a minimally processed vegetable, but harvesting and the following processing can cause a severe stress determining the appearance of accelerated senescence symptoms. The effect of hot air treatment on minimally processed cauliflower was investigated. Florets were put in PE sealed bags before treating at 48°C …

Predictors and mediators of differences in soft drinks consumption according to gender and plans of further education among Norwegian secondary-schoo…

2013

AbstractObjectiveTo explore mediators of gender and educational differences in sugar-sweetened soft drinks consumption (SDC) and whether gender and level of future education moderate the associations of accessibility, modelling, attitudes and preferences with SDC.DesignA cross-sectional school-based survey within the Fruits and Vegetables Makes the Marks (FVMM) project from 2005.SettingThe questionnaires were completed by the pupils in the classroom guided by a trained project worker during one class session. The questionnaire included questions on SDC (times/week), the potential mediators and moderators. Multilevel linear regression models were used to calculate the mediating and moderatin…

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…

Number of meals eaten in relation to weight status among Norwegian adolescents.

2010

Aim: To assess the relationship between number of meals eaten and weight status, and to assess potential confounders of this relationship. Methods: A total of 2870 (participation rate: 85%) 9th and 10th graders (mean age: 15.5 years) at 33 schools completed questionnaires in May 2005. Number of meals was measured with questions asking whether they ate breakfast, lunch, dinner, and supper the day before, giving a scale ranging from zero to four meals/day. Data on gender, height, weight, education plans, intake of fruits and vegetables, consumption of unhealthy snacks, TV/computer time, physical activity level, and dieting were also collected. Results: The proportions of overweight adolescen…

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…

Eight-year trends in food, energy and macronutrient intake in a sample of elderly German subjects.

2005

Time trends in the food and the corresponding energy and macronutrient intake between 1994 and 2002 are investigated as part of the longitudinal study on nutrition and health status in an ageing population in Giessen, Germany (GISELA study). The dietary intake is assessed via a 3 d estimated dietary record especially developed and validated for this study. A total of 2135 records from 532 subjects, aged 60 years and over, are analysed separately according to sex and age groups (born 1904–1928 and born 1929–1942). Results show that the food, energy and macronutrient intake of the GISELA subjects stayed fairly stable over the study period. However, some significant changes in the consumption …
