Abstract
Nutrition is a source of energy, and building material for the human organism. The quality of food has an effect on the quality of individual life. Minerals and vitamins participate in various catalytic and regulatory functions of the main metabolic processes: absorption, transport, redox and biosynthesis of organic compounds, genetic information transfer, etc. Regular consumption of dietary fibers like β-glucans and oat-specific phenolics, antioxidants, and avenanthramides, stimulate innate and acquired immunity, prevent cancer, obesity, reduce glucose, total cholesterol and triglyceride blood levels and regulate the expression of cholesterol-related genes. Thus, all those compounds are vitally important for the normal functional status of the human body. A deficiency in one or another essential nutrient causes disruptions in human metabolism, thus leading to serious illnesses. Plants are the main source of essential nutrients that are bioavailable for humans. One of the most popular groups of staple crops are the small grains crops (SGC), so these crops are most often used for biofortification purposes. Exploiting the potential of plant resources, biofortification is a long-term strategy, aimed at increasing the number of essential micro- and macronutrients in major food sources and ensuring their bioavailability. The most productive way to implement such strategy is the active use of the possibilities offered by collections of plant genetic resources, including SGC, concentrated in various countries of the world. The collections of plant resources contain both cultivated plants and their wild relatives that possess the required composition of micro- and macronutrients. A complex scientific approach to studying plant germplasm collections, together with agricultural practices (soil enrichment with fertilizers with a required composition), genetic biofortification (traditional breeding, marker-assisted selection or genetic engineering tactics), and their combinations will lead to the development of new biofortified cultivars and improvement of old ones, which can be used to solve the problems of unbalanced nutrition (malnutrition or hidden hunger) in different regions of the world.
Highlights
Nutrition is a crucial component in a full-fledged human life, a source of energy, and building material for the whole organism
Traditional biofortification breeding approach involves crosses between crop forms with high amounts of target compounds and varieties adapted to local environments
The experiment performed by George et al in Scotland ascertained that traditional landraces of barley (H. vulgare), small oat (A. strigosa Schreb.) and common oat (A. sativa), when grown on local alkaline soil, accumulated manganese much better than their commercial analogs [76]
Summary
Nutrition is a crucial component in a full-fledged human life, a source of energy, and building material for the whole organism. Declaration on Nutrition, adopted by the Assembly, proposed an integrated strategy to eradicate hunger and end all forms of malnutrition, including undernutrition, micronutrient deficiencies, and obesity on a global scale. It encompasses the entire food system: from the quality of the produced plant raw materials, through the ways of their processing, to the utilization of food production wastes. A solution to this problem may be found if everyone had the right of access to a sufficient amount of safe and wholesome food, which must fully meet the energy requirements of an organism, and ensure its functional adequacy. The main sources of micronutrients necessary for humans are plants [1,3,12,13]
