Objective: Cancer chemoprevention with phytochemicals such as “lutein” derived from the vegetable okra could prove beneficial. Therefore, the objective of this study was to perform a meta-analysis of “lutein” against the breast cancer cell lines (MCF-7) and to establish the possible development of lutein based nutraceuticals. Methodology: A literature survey was performed using online data bases such as PubMed, Google scholar, and EMBASE, from 2000 to 2020 by using keywords such as “Lutein”, “Anticancer activity”, “Breast cancer cell lines”, and “MCF-7”. Studies reported lutein anticancer potentials against MCF-7 were included in the study. Results: Out of 28 studies, 7 research articles fulfilled the inclusion criteria. Meta-analysis data indicated that, a lutein concentration at ≥1 µM was able to reduce the MCF-7 cell viability of 59.837 with a 95% confidence interval (CI): 48.331 to 71.343. Additionally, a forest plot of the cumulative studies also indicated that impact of lutein concentration to reduce the MCF-7 cell viability was around 60%. Moreover, the I2 value of lutein was 74%, which is a considerable heterogeneity. Conclusion: Therefore, based upon the meta-analysis data, the conclusion is that dietary lutein supplementation and fortification of food with clinical data could be an approach to develop a nutraceutical product for preventive, as well as for adjunct therapeutic purposes in various breast cancer subtypes.
