Nowadays, interest in research about pseudocereals has increased worldwide. Pseudocereals can be defined as seeds or fruits of non-grass species that can be consumed similarly to cereals. The most extensively used pseudocereals include quinoa, chia, buckwheat, amaranth, and so on. All of them, have good nutritional and bioactive compounds such as essential amino acids, essential fatty acids, phenolic acids, flavonoids, minerals, and vitamins. Food and Agriculture Organization (FAO) has also reported that there is a buddle of plants that are under-utilized that significantly contribute to improving nutrition and health as well as enhancing food basket and livelihoods of the individual; contributing to future food security and sustainability. Earlier studies also reported that pseudocereals protein-derived peptides have anti-cancerous, anti-inflammatory, anti-hypertensive, hypocholesterolemic, and antioxidant properties. The presence of these interesting properties in pseudocereals enhances the interest to carry out extensive research regarding their health benefits and the way to incorporate them into the diet. In this chapter, we portray different types of pseudocereals with their nutritional benefits for living a healthy and active life.
