Dear Dr.Gilmore ,
I have found the article very informative and was pleased that you have incorporated lifestyle medicine as part of the management of perimenopause. I wanted to mention specifically the area where you mention about complementary therapy and highlight Phytoestrogens like soya should be avoided in women with hormone dependent cancers or those taking tamoxifen. You have highlighted that the evidence on effect of vasomotor symptoms is conflicting too.I have been researching this area myself and hence felt it was important to mention that now there is growing evidence that Soya can be beneficial during perimenopause and can be used in women with hormone dependent breast cancer as well as those taking tamoxifen.
Minimally processed soya foods like soya milk, edamame, tofu, tempeh and miso can be beneficial to overall health including during perimenopause.(1) In the case of cancer this study shows benefits for reducing the risk of breast cancer (13% reduction) and ovarian cancer (48% reduction) amongst several others which included prostate, colorectal, lung and endometrial cancers. The only negative impact highlighted in this meta-analysis was the increased risk of gastric cancer amongst men consuming 1-5 cups of miso soup per day. The study has shown the beneficial effect of soya on hot flushes during perimenopause as well.

The misconception of soya being a phytoestrogen comes from classifying it as an endocrine disruptor. However re...Conflict of Interest:
