Background • Few adults meet recommendations1,2 • Particularly for Vegetables and Fruits and Grain Products • 56% could name four food groups in 1997, and 41% in 2001.3 • Government sources have high credibility, but few people use them4 GarriguetD. Overview of Canadians’ eating habits. Health Rep 2004;2:82-620. Black JL et al. Do Canadians meet Canada's Food Guide's recommendations for fruits and vegetables?

Research Objectives • Examine awareness of Canada’s Food Guide • Examine content knowledge of Canada’s Food Guide • Examine knowledge of estimated energy requirements from Canada’s Food Guide
Methods • 10 minute intercept exit interviews • 2 hospital cafeterias in Ottawa, Canada • Aug/Sept 2013 • Questions on what they ordered, nutrition behaviours and knowledge, and socio-demographics
Measures • Last use of Canada’s Food Guide • Knowledge of food groups • Knowledge of recommended servings of each food group • Vegetables and Fruit = 7-10 • Grain Products = 6-8 • Milk and Alternatives = 2-3 • Meat and Alternatives = 2-3
Measures • Knowledge of recommended calorie intake • Physical activity level • Socio-demographic measures
Analysis • Linear regression • Number of food groups names (0 – 4 groups) • Adjusted for socio-demographic variables • Gender • Age • Ethnicity • Income • BMI • How recently they had viewed the food guide
Sample Characteristics • 59% female • 30.3% 55+ years • 47.3% > $80,000/yrhousehold income • 80.8% White • 53.9% overweight or obese
Ability to recall food groups (n=1,048) Vegetables and Fruit All four groups Milk and Alternatives Meat and Alternatives Grain Products
Ability to recall recommended servings (n=1,048) Vegetables and Fruit All four groups Milk and Alternatives Meat and Alternatives Grain Products
Who recalled more food groups? • Viewed the food guide (p<0.001 for all) • Females(p=0.013) • Younger age categories (p<0.01) • White participants (p<0.001) • Higher income groups (p<0.01 for all) • BMI was not significant
Knowledge of calorie recommendations • 4.7% could identify recommendation specific to age, gender and physical activity level • 29.0%could identify recommendation specific only to age and gender. • 50.0% underestimated • 8.8% overestimated • 12.2% were not able or willing to provide a guess • Answers ranged from 3 to 20,000 calories
Limitations & Strengths Limitations • Sample from hospital cafeterias • Broad categories for “correct” responses Strengths • Unprompted recall of groups and recommended servings
Discussion • Relatively low levels of use of Canada’s Food Guide and very low levels of knowledge of food guide content. • Knowledge was lower among populations that face health disparities • Very few participants knew calorie recommendations • Implications for nutritional literacy and ‘calorie literacy’

Discussion • Relatively low levels of use of Canada’s Food Guide and very low levels of knowledge of food guide content. • Knowledge was lower among populations that face health disparities • Very few participants knew calorie recommendations • Implications for nutritional literacy and ‘calorie literacy’
Conclusion • Poor ‘basic understanding’ of Canada’s official recommendations for diet and nutrition. • Improving knowledge and understanding of CFG may lead to improved nutrition behaviours • Sustained campaigns and coordinated efforts with other nutrition programs may improve uptake.
