A nutrition survey was conducted as part of a larger cardiovascular risk study undertaken by the Manitoba Heart Health Project. A representative group of Manitobans participated in the study, 68% of whom reported their food intake using a food frequency questionnaire. After verifying and merging data from the nutrition and risk factor questionnaires used in the survey, 2,115 were used in data analysis. Results are reported by gender for three age groups. The proportion of food energy derived from total fat varied between 35.3% for senior females and 40.2% for young males. Food of seniors contained a lower proportion of energy from fat than that of either of the two younger age groups. In all three age groups, men consumed diets with a higher proportion of fat than did women. People in regional centres and rural areas obtained higher proportions of energy from fat than did people in Winnipeg. Fat intake from butter, margarine or spreads eaten with bread and potatoes was high compared to the intake from other foods.
