Some seeds have relevance in the diet. It is consumed as aggregate in dairy baking products. Commonly used are: chia (Salvia hispanica), Flax (Linum usitatissimum ) , Quinoa ( Chenopodium quinoa) and Amaranth (Amaranthus caudatus L). If well enough is known about their chemical composition, such as high-protein, energy and omega 3 and 6 fatty acids, little is known about its mineral composition. The aim of this work was to evaluate the mineral composition (Ca, K, Mg, Na, Fe and P) in these seeds. The seeds wereobtained from shops in the surrounding area, for human consumption. The organic matter was removed by a microwave by acid digestion. The elements were subsequently determined by inductively coupled plasma atomic emission spectroscopy (ICP-OES). The mean values (mg/Kg): Amaranthus caudatus L: Ca: 1577,97 ; K: 5234,29 ; Mg: 3156,53 Na: 233,38 ; Fe: 67,42; P: 6281,97. Chenopodium quinoa: Ca: 436,45; K:5976,61; Mg: 1736,74; Na: 233,38
