Hair as a biomarker reflecting the intake of minerals could be helpful in correcting errors in the diet of children associated with inadequate consumption of magnesium, iron and zinc, and thus it can prevent their deficiency or excess in the body. The aim of the study was to evaluate the relationship between the intake of magnesium, iron and zinc and the concentration of these minerals in children’s hair. The study was conducted in Warsaw (Poland) among 148 children aged 7-9. Anthropometric measurements (height, body weight) were performed on the children and the BMI values were calculated. The dietary intake of magnesium, iron and zinc in the studied children was assessed by 3-day food records method. The children were divided into four groups based on quartiles of intake of individual minerals. The concentration of iron, zinc and magnesium in the children’s hair was determined by atomic absorption spectrometry (AAS). The majority of the children had a normal height (91%), weight (93%) and adjusted BMI (74%). Relationships between the intake of magnesium (r=0.239, p=0.007), iron (r=0.247, p=0.004) and zinc (r=0.314, p
