Food group contributions to energy, carbohydrate, protein, total fat, saturated fat, cholesterol, fiber, calcium, iron, folate, zinc, vitamins A and C were evaluated for Canadian adults aged 18--65 years. Twenty four hour recall data from the 1997--98 Food Habits of Canadians survey were used. Mean nutrient intakes exceeded the RNI for all age-gender groups except, calcium for older women. Mean iron (women 18--49 years) and zinc (men and women 50--65 years) intakes were borderline. The differences in food group contribution to nutrient intake among smokers and non-smokers indicated that smokers generally obtained nutrients from foods higher in energy and fat and lower in other nutrients. Important food sources for individuals meeting the RNI for calcium were fluid milk and cheese. Important sources of folate were citrus fruit juices, breads, and lettuce/cabbages/greens as were cereals and beef/veal for iron. Zinc sources were primarily other beef cuts or ground beef.
