Abstract:

Objective Dairy products are sources of protein and micronutrients important in a healthy diet. The purpose of the present analysis was to estimate consumption of dairy products by Brazilians and identify contributions of dairy products to nutrient intakes. Design Dairy consumption data were obtained from 24 h dietary records. Dairy products were defined as milk (including flavoured), cheese and yoghurt. Estimates of dairy product intakes were generated for all individuals, individuals in urban and rural households and for age groups 10–18 years, 19–59 years and ≥60 years. Contributions to nutrient intakes were estimated for the total sample and sub-populations. Setting Nationwide cross-sectional survey, 2008–2009. Subjects Nationally representative sample of individuals aged ≥10 years in the Individual Food Intake survey, a component of the Brazilian Household Budget Survey (n 34 003). Results Among individuals aged ≥10 years, per capita intake of dairy products was 142 (SE 2·1) g/d. Dairy product intake was higher among individuals in urban compared with rural areas and among groups 10–18 years and ≥60 years compared with adults aged 19–59 years. Dairy products accounted for 6·1 % of daily energy intake, 7·3 % of protein, 16·9 % of saturated fat, 11·1 % and 4·3 % of total and added sugars, respectively, and 10·2–37·9 % of daily Ca, vitamin D, P, vitamin A and K. Conclusions Dairy products were substantial contributors to daily intakes of selected nutrients of concern in Brazil, although mean daily dairy product consumption was less than a typical portion. Education efforts in Brazil to raise awareness about the nutritional role of dairy foods may serve to improve overall diet quality.
