OBJECTIVE To compare dietary intakes of Maori, Pacific Islands and European men and women in New Zealand. METHODS A food frequency questionnaire was used to calculate nutrient intakes of 5523 New Zealand workers aged 40 years and over (3997 men, 1524 women) from a cross-sectional survey carried out between 1988 to 1990. RESULTS Compared with European men and women, Maori women and Pacific Islands men and women consumed larger amounts of total energy per day. Age-adjusted nutrients expressed as percentage contribution to total energy intakes showed that Maori and Pacific Islands men and women consumed less carbohydrate, fibre and calcium, and more protein, fat, saturated fat and cholesterol than European men and women, respectively. These results were consistent with fewer servings of cereal and cheese per month, and more servings of red meats, fish and eggs in Maori and Pacific Islands participants compared with Europeans, after adjusting for age and total energy intakes. Pacific Islands men and women also consumed more servings of chicken, fewer cups of milk and fewer servings of fruit per month compared to Europeans. Maori men and women consumed more slices of bread and fewer servings of vegetables per month compared to European men and women. CONCLUSIONS There were striking differences in dietary habits, food selections and cooking practices between European, Maori and Pacific Islands participants. Dietary intakes of Maori workers were closer to those of Europeans than those of Pacific Islands participants. Ethnic differences were due to larger portion sizes and increased frequency of most foods in Maori and Pacific Islands participants.
