Abstract

Genetically modified (GM) foods have revolutionized agricultural biotechnology since their debut in the mid-1990s, sparking debates about their safety, environmental impact, and potential to solve global food security issues. This review offers a comprehensive look at the global status of GM foods, covering their development, various genetic modifications, and adoption rates across different regions. It delves into the regulatory frameworks that govern GM foods in major markets, noting the variations in regulatory approaches and strictness. The review highlights the benefits of GM foods, such as higher agricultural productivity, better environmental sustainability, improved food security, and enhanced nutritional value. It also addresses the ongoing controversies and challenges, including safety concerns, environmental risks, ethical questions, and public perception issues. Looking ahead, the paper considers the future of GM foods, focusing on advancements in biotechnology, possible changes in policies and regulations, and how GM crops can be integrated into sustainable agriculture practices. By providing a balanced perspective, this review aims to guide stakeholders in making informed, evidence-based decisions about the role of GM foods in addressing global food challenges.

Abstract

Background: The complex problems of different chronic degenerative diseases are spreading in human health across the globe. To combat this problem, fruits are the effective gear proved by many epidemiological studies. The aim of the study was to determine the antioxidant activity and three bioactive compounds like total flavonoids, total polyphenols and total anthocyanins in 23 species of fruits available in Bangladeshi market. Methods: Antioxidant activity (AOA) and bioactive compounds of fruits were determined by UV-visible spectroscopy. Antioxidant activity was undertaken by DPPH scavenging assay, total polyphenol content (TPC) was measured by folin-ciocalteu method and total flavonoid content (TFC) content was measured by aluminium chloride colorimetric method. Results: Among 23 species of fruits, AOA was higher in Katajamin (303 mg/100 g) followed by Dragon Fruits (171 mg/100 g), Guava (131 mg/100 g), Bael (130 mg/100 g) and average value was 125 mg/100 g of extract. TPC was varied from 10 to 305 mg GAE/100 g and average value was 87 mg GAE/100 g. Mango (305 mg GAE/100 g) showed higher TPC, followed by Pome Granate (222 mg GAE/100 g), Apple (207 mg GAE/100 g), Katajamin (141 mg GAE/100 g) and Bael (130 mg GAE/100 g). Again, TFC was ranged from Ashari (063.94 mg QE/g) to Tomato (8413.69 mg QE/g) and the average TFC was 37 mg QE/g. In addition, total anthocyanin content (TAC) was highest in Mango (1423.46 mg TA/100 g) and lower in Ashari (020.74 mg TA/100 g). There was a significant correlation (p?0.05) between antioxidant activity and bioactive compounds and among the bioactive compounds. Conclusion: Important messages from this study are, majority of the rare fruits are the important sources of antioxidant and bioactive compounds which helps to reduce the risk of chronic degenerative diseases and can be used in food processing industry for nutraceutical product development.

Abstract

The increasing interest in nutraceuticals has spotlighted the potential of local foods as sources of health-promoting bioactive compounds. This narrative review explores the nutraceutical value of local foods, emphasizing the processing methods that enhance their health benefits. By examining a variety of indigenous food sources, we delve into the specific bioactive components they contain, such as polyphenols, flavonoids, vitamins, and minerals. Advanced processing techniques, including fermentation, encapsulation, and enzymatic treatments, are discussed for their roles in maximizing the bioavailability and efficacy of these compounds. Furthermore, the health impacts of these nutraceuticals are analyzed, focusing on their potential to prevent and manage chronic diseases such as diabetes, cardiovascular diseases, and cancer. This review underscores the importance of leveraging local biodiversity to develop sustainable and effective nutraceutical products, offering insights into future research directions and applications in the nutraceutical industry. By integrating traditional knowledge with modern processing technologies, the potential of local foods as nutraceuticals can be fully realized, contributing to both public health and local economies.
