Dragon fruit: Nutritional composition and therapeutic value

Abstract

This review explores the nutritional profile and therapeutic benefits of dragon fruit (Hylocereus spp.), also known as pitaya. Dragon fruit is rich in vitamins, minerals, fibre, and antioxidants, particularly betalains and polyphenols, which contribute to its health-promoting properties. Studies have highlighted dragon fruit’s role in supporting cardiovascular health, regulating blood sugar levels, and enhancing immune function. This review synthesizes current research on the nutritional composition and potential health benefits of dragon fruit, discussing its therapeutic value for managing metabolic disorders, improving digestion, and preventing chronic diseases.
