A healthy diet is directly associated with a nutrient-rich and toxic contaminant poor intake. A diet poor in diversity can lead to micronutrient deficiency. The intake of functional foods can provide benefits in the prevention and treatment of diseases. Oats are a functional food; are a source of soluble fiber, lipids, proteins, vitamins, minerals, and polyphenols; and are low in carbohydrate content. Thus, in this study, we characterize mineral accumulation, fatty acid composition, and the absence of contaminants in oat genotypes to evaluate the potential of this cereal as food to minimize the effects of micronutrient deficiency. Most of the oat genotypes showed higher mineral levels than other cereals such as wheat, rice, and maize. FAEM 5 Chiarasul, Barbarasul, UPFA Ouro, URS Altiva, URS Brava, and URS Taura showed higher iron concentration while URS Brava showed the highest zinc concentration. The oat genotypes did not show significant arsenic, strontium, and cadmium accumulation. Considering the accumulation of trace elements in the grain, little genetic diversity among the analyzed oat accessions was detected, dividing into two groups. Regarding fatty acid composition, IPR Afrodite, FAEM 4 Carlasul, FAEM 5 Chiarasul, URS Taura, Barbarasul, and URS 21 showed higher essential fatty acid concentrations. These genotypes can be used in crosses with URS Brava, which displayed a higher Fe and Zn accumulation and is genetically distant from the other cultivars. Oat is a functional food showing ability for the accumulation of minerals and also essential fatty acids.

巴西生长的白燕麦基因型的矿物质和脂肪酸含量变化。

健康的饮食与营养丰富且有毒的污染物摄入不足直接相关。缺乏多样性的饮食会导致微量营养素缺乏。摄入功能性食品可以为疾病的预防和治疗提供益处。燕麦是一种功能性食品;是可溶性纤维、脂质、蛋白质、维生素、矿物质和多酚的来源;并且碳水化合物含量低。因此,在这项研究中,我们表征了燕麦基因型中矿物质积累、脂肪酸组成和污染物的缺乏,以评估这种谷物作为食品的潜力,以最大限度地减少微量营养素缺乏的影响。大多数燕麦基因型的矿物质含量高于其他谷物,如小麦、大米和玉米。FAEM 5 Chiarasul、Barbarasul、UPFA Ouro、URS Altiva、URS Brava、URS Taura 显示出较高的铁浓度,而 URS Brava 显示出最高的锌浓度。燕麦基因型没有显示出显着的砷、锶和镉积累。考虑到谷物中微量元素的积累,在分析的燕麦种质中检测到很少的遗传多样性,分为两组。关于脂肪酸组成,IPR Afrodite、FAEM 4 Carlasul、FAEM 5 Chiarasul、URS Taura、Barbarasul 和 URS 21 显示出更高的必需脂肪酸浓度。这些基因型可用于与 URS Brava 杂交,后者表现出更高的 Fe 和 Zn 积累,并且在遗传上与其他品种相距甚远。燕麦是一种功能性食品,具有积累矿物质和必需脂肪酸的能力。燕麦基因型没有显示出显着的砷、锶和镉积累。考虑到谷物中微量元素的积累,在分析的燕麦种质中检测到很少的遗传多样性,分为两组。关于脂肪酸组成,IPR Afrodite、FAEM 4 Carlasul、FAEM 5 Chiarasul、URS Taura、Barbarasul 和 URS 21 显示出更高的必需脂肪酸浓度。这些基因型可用于与 URS Brava 杂交,后者表现出更高的 Fe 和 Zn 积累,并且在遗传上与其他品种相距甚远。燕麦是一种功能性食品,具有积累矿物质和必需脂肪酸的能力。燕麦基因型没有显示出显着的砷、锶和镉积累。考虑到谷物中微量元素的积累,在分析的燕麦种质中检测到很少的遗传多样性,分为两组。关于脂肪酸组成,IPR Afrodite、FAEM 4 Carlasul、FAEM 5 Chiarasul、URS Taura、Barbarasul 和 URS 21 显示出更高的必需脂肪酸浓度。这些基因型可用于与 URS Brava 杂交,后者表现出更高的 Fe 和 Zn 积累,并且在遗传上与其他品种相距甚远。燕麦是一种功能性食品,具有积累矿物质和必需脂肪酸的能力。在分析的燕麦种质中检测到很少的遗传多样性,分为两组。关于脂肪酸组成,IPR Afrodite、FAEM 4 Carlasul、FAEM 5 Chiarasul、URS Taura、Barbarasul 和 URS 21 显示出更高的必需脂肪酸浓度。这些基因型可用于与 URS Brava 杂交,后者表现出更高的 Fe 和 Zn 积累,并且在遗传上与其他品种相距甚远。燕麦是一种功能性食品,具有积累矿物质和必需脂肪酸的能力。在分析的燕麦种质中检测到很少的遗传多样性,分为两组。关于脂肪酸组成,IPR Afrodite、FAEM 4 Carlasul、FAEM 5 Chiarasul、URS Taura、Barbarasul 和 URS 21 显示出更高的必需脂肪酸浓度。这些基因型可用于与 URS Brava 杂交,后者表现出更高的 Fe 和 Zn 积累,并且在遗传上与其他品种相距甚远。燕麦是一种功能性食品,具有积累矿物质和必需脂肪酸的能力。它显示出更高的铁和锌积累,并且在遗传上与其他品种相距甚远。燕麦是一种功能性食品,具有积累矿物质和必需脂肪酸的能力。它显示出更高的铁和锌积累,并且在遗传上与其他品种相距甚远。燕麦是一种功能性食品,具有积累矿物质和必需脂肪酸的能力。
