Study design: Systematic Review
Abstract: Urbanization and globalization are transforming socio-ecological systems, affecting dietary diversity, natural resource availability, and the transmission of traditional knowledge. These changes have led to the inclusion of exotic plants in modern diets and health practices. This study investigates the potential of dragon fruit (Hylocereus sp.) and broccoli (Brassica oleracea var. italica Plenck) in functional foods, nutraceuticals, disease prevention, and linking their role in promoting sustainable dietary practices. A systematic review of literature was conducted using Scopus, Web of Science, PubMed, and Google Scholar. Out of 579 sources screened, 145 relevant studies were analyzed to gather relevant data on bioactive compounds, nutritional content, traditional uses, and experimental evidence supporting their functional and therapeutic effects. Pitaya and broccoli are rich in bioactive compounds such as flavonoids, polyphenols, betalains, vitamins, and glucosinolates, which collectively display antioxidant, anti-inflammatory, and immune-modulating effects. Pitaya demonstrates potential benefits in prebiotic modulation, liver and cardiovascular support, anemia management, wound healing, and antiviral activity against SARS-CoV-2. Broccoli and its sprouts exhibit anti-diabetic, anti-cancer, neuroprotective, anti-obesity, pulmonary, and antimicrobial properties, primarily mediated through sulforaphane and activation of Nrf2 pathways. The consumption and incorporation into nutraceuticals and plant-based supplements extend beyond individual health to support global sustainability and food security goals. Their ease of cultivation, nutritional richness, and potential in nutraceuticals and functional foods diversify diets, reduce reliance on synthetic treatments, and strengthen food system resilience. Dragon fruit and broccoli exemplify this transformative potential, offering accessible solutions for chronic disease prevention. Further research on bioavailability and clinical efficacy remains crucial.
