This paper aims to verify whether cereal products are a good source of Cu, Mn, Fe, and Zn in the diets of Poles. The study material comprised of 445 cereal products including baked goods, breakfast cereals and groats, pasta, and rice. Products that required culinary treatment (pasta, groats, rice) were boiled in drinking quality water as recommended by the producer. The content of Cu, Mn, Fe, and Zn was determined by using the FAAS method. The average content of microelements in the analyzed products can be represented as Fe (17.9 mg kg ± 10.3) > Zn (12.4 mg kg ± 5.2) > Mn (9.6 mg kg ± 6.7) > Cu (3.9 mg kg ± 2.9). Considering the daily requirement of the analyzed minerals among adult Poles, it was determined that cereal products supply 58% RDA Cu, 61% AI Mn (men)-78% AI Mn (women), 19% RDA Fe (women)-34% RDA Fe (men), and 16% RDA Zn (men)-22% RDA Fe (women). Baked goods account for as much as about 90% of all Cu, Mn, Fe, and Zn consumed as cereal products in a daily diet. Based on the results, it can be concluded that cereal products are the main source of Cu, Mn, Fe, and Zn in the diets of Poles. In connection with low assimilability of minerals, they should not be considered the fundamental source of those microelements in the diets of Poles.
本文旨在验证谷物产品是否是波兰人饮食中 Cu、Mn、Fe 和 Zn 的良好来源。研究材料包括 445 种谷物产品，包括烘焙食品、早餐麦片和麦片、面食和大米。需要烹饪处理的产品（面食、麦片、大米）按照生产商的建议用饮用水煮沸。使用 FAAS 法测定 Cu、Mn、Fe 和 Zn 的含量。分析产品中微量元素的平均含量可表示为 Fe（17.9mgkg±10.3）>Zn（12.4mgkg±5.2）>Mn（9.6mgkg±6.7）>Cu（3.9mgkg±2.9）。考虑到波兰成年人对分析矿物质的日常需求，确定谷物产品提供 58%RDA Cu、61%AI Mn（男性）-78%AI Mn（女性）、19%RDA Fe（女性）-34%RDA Fe（男性）和 16%RDA Zn（男性）-22%RDA Fe（女性）。烘焙食品约占波兰人日常饮食中所有作为谷物产品消耗的 Cu、Mn、Fe 和 Zn 的 90%。基于这些结果，可以得出结论，谷物产品是波兰人饮食中 Cu、Mn、Fe 和 Zn 的主要来源。鉴于矿物质的低吸收率，它们不应被视为波兰人饮食中这些微量元素的基本来源。
