Triticale (× Triticosecale Wittmack) is a hybrid cereal prepared by crossing wheat and rye. Triticale grain contains substances that have a positive effect on reducing the risk of cardiovascular disease, obesity, cancer, and type 2 diabetes, as well as increasing body's immune response and intestinal function, which warrants a need for greater attention to research on triticale crop's nutritional composition. This review covers the most recent research on the nutritional composition of triticale grain in comparison to other cereals, its role in the food industry, and its usage as a food, providing a scientific foundation for triticale's further development as a sustainable crop. Due to the wide variety of chemical compounds revealed in triticale grain, it has the potential to be utilised as a substitute cereal for various food and beverages.
