Objectives: Our aim in this work was to ascertain Canadian registered dietitians' (RDs) use of the 2018 Diabetes Canada nutrition therapy (NT) recommendations and to identify the degree of agreement with facilitator-to-use statements.

Methods: A national 28-item anonymous cross-sectional survey of RDs who counsel people with diabetes was conducted.

Results: Three hundred sixty RDs responded to the survey, but some questions had fewer responses.

This study compared the caloric and nutrient values of packed lunch contents and consumption in the Balanced School Day (BSD) (two 20 min eating periods) versus the Traditional Schedule (TS) (one 20 min lunch). Foods consumed during school were assessed by direct food observation in 321 grade 3 and 4 students, aged 7−10 years, at 9 BSD and 10 TS elementary schools in Ontario. Packed lunch contents in the BSD were significantly higher than the TS in energy (3128.

To evaluate foods advertised in discount and premium grocery flyers for their alignment with Canada's 2007 Food Guide (CFG) and assess if alignment differed by food category, season, page location, and price. Weekly flyers (n = 192) were collected from discount and premium grocery chains from each of 4 seasons. Health Canada's Surveillance Tool was used to assess food items as in-line or not in-line with CFG.

To examine the relationship between Food and Nutrition graduates' involvement in faculty-supervised extracurricular experiential learning activities (FEEs) and the development of dietetic competencies. An original web-based survey, assessing involvement in FEEs and self-perceived level of Canadian dietetic competencies, was administered to Brescia University College Food and Nutrition graduates for graduation years 2011-2017. Competency scores were calculated for each respondent in 4 practice areas (Professional Practice, Communication and Collaboration, Population and Public Health, and Management), and summed for a Total Competency Score.

Purpose: Parents influence the foods their children consume and often provide proxy reports of this intake. One way parents exert this influence is by providing home-packed lunches. This study compared parental reports of foods packed in children's lunches with what was actually packed and identified parental barriers and facilitators to packing lunches.

Purpose: To compare sales of Food Resources and Education for Student Health (FRESH) Approved versus non-FRESH Approved menu cycle items pre- and postimplementation of the FRESH program.

Methods: Sales data from 2011-2015 of FRESH Approved versus non-FRESH Approved menu items were analyzed. Fruit and milk items sold, net sales, and the cost of free fruit and milk redeemed through the FRESH Reward Card (FRC) program, were also analyzed.

This study assessed the strength of the association between socioeconomic status (SES) and low birth weight (LBW) and preterm birth (PTB) in Southwestern Ontario. Utilizing perinatal and neonatal databases at the London Health Science Centre, maternal postal codes were entered into a Geographic Information System to determine home neighbourhoods. Neighbourhoods were defined by dissemination areas (DAs).

University students experience a life transition that often results in poor dietary behaviors and weight gain. Adequate food skills may improve diet quality and prevent chronic disease. Research is limited, however, on students' food skills and food-related behaviors.

Purpose: To assess the type and quantity of foods children brought and consumed at school in the balanced school day (BSD), with two 20-minute eating periods, versus the traditional schedule (TS), with one 20-minute lunch.

Methods: Direct observation identified food items and amounts in BSD and TS lunches of grade 3 and 4 students (n = 321).

Results: The mean (SD) servings of foods packed in BSD lunches were significantly higher than the TS lunches for milk and alternatives (0.

Purpose: Peer education (PE) has been used effectively in nutrition; however, research examining dietitians' attitudes regarding PE is lacking.

Methods: An online survey was sent to a random sample of 1198 Dietitians of Canada members to assess attitudes regarding PE by practice area.

Results: A representative sample of dietitians by practice area and location was obtained (n = 229; 19%).

Objective: The balanced school day (BSD) is an alternative elementary school schedule whereby children have 2 20-minute eating periods instead of 1 20-minute lunch, as is found in the traditional schedule (TS). We assessed the glycated hemoglobin (A1C) levels of children with type 1 diabetes in the TS vs. the BSD because 2 eating periods have the potential to impact blood glucose control.

One in four Canadian adults is obese, and more women are entering pregnancy with a higher body mass index (BMI) than in the past. Pregnant women who are overweight or obese have a higher risk of pregnancy-related complications than women of normal weight. Gestational weight gain (GWG) is also associated with childhood obesity.

Background: The Balanced School Day (BSD) is a scheduling policy that has the potential to impact children's food behaviors because students are provided with two 20-minute eating opportunities versus the traditional 20-minute lunch.

Methods: We aim to raise awareness of this grassroots academic policy and its potential consequences to inform future decision making and minimize potential unintended negative health consequences.

Results: While there is limited research on this schedule, it has been shown that there is less time lost in transition from classroom to recess.

Clinical practice guidelines (CPGs) for the nutritional management of diabetes mellitus have evolved considerably over the last 25 years. As major diabetes associations have focussed on the individualization of nutrition therapy, there has been a move toward a broader more flexible macronutrient distribution that emphasizes macronutrient quality over quantity. There is now a call for the integration of food- and dietary pattern-based approaches into diabetes association CPGs.

Increased attention has been directed toward the school food environment because children consume important contributions toward their daily food intake while at school. In Canada, most elementary school students bring a lunch to school and there are minimal data on the composition and consumption of these lunches. Dietary assessment of home-packed lunches is challenging compared with assessment of standardized school meals due to greater diversity of items, nonstandard portions, and opaque containers.

Background: The alanine-for-threonine substitution at codon 54 (A54T polymorphism) in the fatty acid-binding protein 2 gene (FABP2) has been associated with hypertriglyceridemia and insulin resistance. Obese and diabetic T54 carriers have greater postprandial lipemia than do A54 homozygotes. The T54 protein isoform is also associated with increased triacylglycerol secretion in vitro.
