We evaluated the nutritional factors of underutilized cereals (spelt, emmer, einkorn, millet, foxtail millet, semiperennial rye, naked oat, and naked barley) and buckwheat. The basic food components as well as minor nutrients were determined. The analyses included dry matter, ash, protein, dietary fiber, fat, fatty acids, amino acids, minerals, and lipophilic and hydrophilic vitamins. Rutin was also determined in buckwheat. We hope to offer new recipes for the healthy food production and for special dietary use (diabetes, celiac disease, phenylketonuria diet, etc.). Use of the germinated seeds is also suggested. The examples of some healthy food products in the Czech Republic are mentioned.
