Potential studies and evidence regarding nutrient nanoencapsulation combined with emulsion-based delivery systems are relatively limited. Therefore, for the importance issue of health vision, with this critical opinion to the editor is scientifically important to invite worldwide researchers to raise their concern for clinical research and the development of plant-based lutein nanoencapsulation in staple foods in alleviating nutritional problems for the eyes, which has not been reported before. This is in line with the WHO World Report which aimed to overcome the challenge regarding vision and galvanizing action, one of which is through innovation and research. With the hypothesis that, through this opinion will increase the awareness of scientists to improve clinical studies on the stability and bioaccessibility of lutein for health vision concern. As our hypothesis and objectives, we hope that this critical short opinion to the editor will assist efforts to reduce the burden of eye conditions and vision loss to achieve the Sustainable Development Goals (SDGs), particularly SDG 3.8 on universal health coverage through lutein-plant based nanoencapsulation clinical studies by worldwide researchers. Finally, it is very important and needed an effort to improve clinical studies focus on the stability and bioaccessibility of lutein for health vision via lutein-plant based nanoencapsulation approaches. Moreover, the benefit of lutein supplementation for the health vision might be limited by its bioaccessibility and bioavailability. Future studies and approaches should employ strategies that could overcome the foregoing limitations, of which is through nanoencapsulation approach. Something new has been synthesized in this work, "Because, every human eye, is the eye of the world".
Background: This study aimed to determine the potential anti-aging effects of sea grapes and tempe (fermented soybeans) collagen particle size, by measuring the activities of anti-glycation, antioxidant, and tyrosinase inhibitors. Methods: Collagen was isolated from freeze-dried sea grapes and tempe powder and treated with different NaOH concentrations (0.10 M; 0.20 M; 0.30 M), and CH 3COOH 1 M solution, separately. The collagen particle size was adjusted by stirring at 1000 rpm for 5 and 10 hours. 2,2-diphenyl-1-picrylhydrazyl (DPPH) was used to measure the antioxidant activity, and L-tyrosine and L-DOPA (l-3,4-dihydroxyphenylalanine) was used as a marker of tyrosine inhibition. Results: The collagen treated with 0.10 M NaOH produced the highest collagen yield (11.65%), and the largest particle size (2455 nm). Additionally, this collagen, when treated for 5 hours, exhibited 24.70% antioxidant activity, 62.60% anti-glycation, 8.97% L-tyrosine, and 26.77% L-Dopa inhibition activities. Meanwhile, the collagen treated for 10 hours had a 9.98% antioxidant activity, 41.48% anti-glycation, 7.89% L-tyrosine, and 2.67% L-Dopa inhibition activity. Conclusion: Sea grapes and tempe collagen powder treated with 0.10 M NaOH and stirred for 5 hours, possess the best potential anti-aging properties as a functional food.
Diabetes and obesity are chronic diseases that are a burden to low- and middle-income countries. We conducted this systematic review to understand gene-diet interactions affecting the Southeast Asian population's risk of obesity and diabetes. The literature search was performed on Google Scholar and MEDLINE (PubMed) search engines independently by four reviewers who evaluated the eligibility of articles based on inclusion criteria. Out of 19,031 articles, 20 articles examining gene-diet interactions on obesity and/or diabetes-related traits met the inclusion criteria. Three (Malaysia, Indonesia, and Singapore) out of eleven Association of Southeast Asian Nations (ASEAN) countries have conducted studies on gene-diet interactions on obesity and diabetes. From the 20 selected articles, the most common interactions were observed between macronutrients and genetic risk score (GRS) on metabolic disease-related traits in the Malay, Chinese, and Indian ethnicities. Overall, we identified 29 significant gene-diet interactions in the Southeast Asian population. The results of this systematic review demonstrate ethnic-specific gene-nutrient interactions on metabolic-disease-related traits in the Southeast Asian population. This is the first systematic review to explore gene-diet interactions on obesity and diabetes in the Southeast Asian population and further research using larger sample sizes is required for better understanding and framing nutrigenetic approaches for personalized nutrition.
