Abstract
Background: Breast cancer is a serious disease among women and that the major cause of death among women who had this disease in the world. Many articles suggest more consume soy, which has isoflavone, could prevent breast cancer. However, the amount of isoflavone for preventing of breast cancer remains in discussion. Hence, the researchers are interested in studying the amount of isoflavones in soybeans that could prevent breast cancer among women.
Method: The systematic review and meta-analysis were based on papers published from 2010 to 2019 through PubMed, Science Direct, Web Of Science, World Health Organization (WHO), International Agency For Research On Cancer (IARC), Center For Disease Control And Prevention, Cellular And Molecular Biomechanism Laboratory, United States Department Of Agriculture, and National cancer institute. We included 8 papers that met the inclusion criteria and then data was analyzed.
Result: The consumption of isoflavones among Asians is around 25.42 mg/d could reduce the risk of breast cancer, while, approximately 5.79 mg/d. would suggest for Europeans.
Conclusion: The amount of isoflavones to prevent breast cancer for Asians is 25.42 mg/d and for Europeans is 5.79 mg/d
