: The study of dietary antioxidants has gained prominence owing to the elucidation of the deleterious effects of oxidative stress to the human body. Objective: To evaluate the Brazilian population's intake of antioxidant nutrients and their association with the nutritional status.
: A cross-sectional study was carried out including secondary data on food consumption of 33,459 individuals from both sexes, aged 10 years or older, from all Brazilian regions based on microdata of the "2008-2009 Household Budget Survey, Brazilian Dairy Survey." The content of vitamins E, A, and C; zinc; manganese; copper; and selenium from 188 food items, divided into 12 groups, according to the habitual consumption form was analyzed. The means of antioxidant nutrient intake according to the nutritional status were compared using Bonferroni's t-test.
: Higher percentages of insufficient intake of vitamins than antioxidant minerals were seen. A significant difference in the intake of vitamin E as to the nutritional status was noticed, wherein the intake in overweight individuals was lower than in those with proper weight. Participants with low weight presented lower intake of almost all antioxidant minerals, except for copper, in which the intake of participants with low weight was equal to those with normal weight.
: High percentages of insufficient intake of antioxidant nutrients were observed in the studied population, especially vitamins. It was also found that the intake of antioxidant nutrients varied based on nutritional status, gender, and life stage.
由于氧化应激对人体有害影响的阐明，膳食抗氧化剂的研究变得日益重要。目的：评估巴西人群抗氧化营养素的摄入量及其与营养状况的关联。
开展了一项横断面研究，纳入了基于“2008 - 2009年家庭预算调查，巴西乳制品调查”微观数据的来自巴西所有地区、年龄在10岁及以上的33459名男女的食物消费二级数据。分析了188种食物（根据习惯消费形式分为12组）中维生素E、A、C；锌；锰；铜和硒的含量。使用邦费罗尼t检验比较了根据营养状况划分的抗氧化营养素摄入量均值。
维生素摄入不足的百分比高于抗氧化矿物质。观察到维生素E摄入量在营养状况方面存在显著差异，超重个体的摄入量低于体重正常者。体重低的参与者几乎所有抗氧化矿物质的摄入量都较低，除了铜，体重低的参与者的铜摄入量与体重正常者相等。
在所研究的人群中观察到抗氧化营养素摄入不足的比例很高，尤其是维生素。还发现抗氧化营养素的摄入量因营养状况、性别和生命阶段而异。
