The manuscript had been written by Dr Graham Kelly who had founded a company to commercialise isoflavone supplementation in men and women. Dr Kelly’s journey in cancer research started in the 1980s when a friend with bowel cancer asked him to look into the science of it. Dr Kelly was intrigued by the epidemiological differences in cancer rates between populations. For example, Japanese who migrate to the US go to the US breast cancer rate in a generation. The US breast cancer rate is five times the Japanese breast cancer rate. The difference in cancer rate is not genetic, it is obviously dietary. So what is the difference in diet that is causing the difference in cancer incidence? A big difference is isoflavone consumption. Amongst the Japanese, it is an average of 40 mg per day. The US average is 3 mg per day.
