If you believe all those headlines, there would be little you could eat. You might starve to death trying to avoid eating anything that increases your risk of cancer.<\/p>\n<p>So, it\u2019s important to ask which of those warnings are true and which are just myths.<\/p>\n<p>For example, a few days ago, a friend called me and said, \u201cI just heard that resveratrol is estrogenic and causes breast cancer. Should I read the labels of the herbal supplements I take and avoid anything with resveratrol in it.\u201d<\/p>\n<p>I assured her that this was just a myth. The likelihood that resveratrol and related polyphenols cause breast cancer is very low. And if she was concerned about breast cancer, there were much more important things to worry about.<\/p>\n<p>But as I started to explain why it was a myth, I realized the explanation was complex. I was able to explain it to my friend in a 20-minute discussion. But it was then I realized I needed to write a \u201cHealth Tips From the Professor\u201d article to help explain it to the general public.<\/p>\n<h2 style=\"text-align: center;\"><span style=\"color: #3366ff;\"><strong>Why Are We Concerned?<\/strong><\/span><\/h2>\n<p><a href=\"https:\/\/www.chaneyhealth.com\/healthtips\/which-foods-affect-stroke-risk\/beautiful-woman-with-questioning-expression-and-question-marks-a\/#main\" rel=\"attachment wp-att-3863\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-medium wp-image-3863\" src=\"https:\/\/www.chaneyhealth.com\/healthtips\/wp-content\/uploads\/2020\/03\/Questioning-Woman-Depositphotos_16018497_s-2015-300x223.jpg\" alt=\"Questioning Woman\" width=\"300\" height=\"223\" srcset=\"https:\/\/www.chaneyhealth.com\/healthtips\/wp-content\/uploads\/2020\/03\/Questioning-Woman-Depositphotos_16018497_s-2015-300x223.jpg 300w, https:\/\/www.chaneyhealth.com\/healthtips\/wp-content\/uploads\/2020\/03\/Questioning-Woman-Depositphotos_16018497_s-2015.jpg 500w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a>You might be asking, \u201cWhy is this such a big deal? Why do we care if something has estrogenic properties?\u201d Let me start at the beginning.<\/p>\n<p>When I first started teaching medical students in 1972, hormone replacement therapy (a combination of estrogen and progesterone) was thought to be a safe and effective treatment for menopausal symptoms and post-menopausal bone loss, and it was very widely prescribed.<\/p>\n<p>That practice came to a screeching halt in 2002 when the Woman\u2019s Health Initiative study showed that it increased the risk of breast, endometrial, and ovarian cancer. Today,<\/p>\n<ul>\n<li>The hormone composition of hormone replacement therapy has been changed.<\/li>\n<\/ul>\n<ul>\n<li>It is only prescribed for severe menopausal symptoms. And drugs are the treatment of choice to reduce post-menopausal bone loss.<\/li>\n<\/ul>\n<ul>\n<li>It is prescribed for the shortest possible time to limit exposure.<\/li>\n<\/ul>\n<p>These simple changes in hormone replacement therapy represent the single most important intervention for reducing breast cancer risk in the past 50 years. Yes, you heard that right. These changes were more effective than any other medication or preventative strategy for reducing the number of women developing and dying from breast cancer.<\/p>\n<p>This lesson made a big impression on the medical community. So, it is easy to understand why anything resembling estrogen is immediately suspected of increasing the risk of breast cancer. But the reality is far more complicated. So, it\u2019s time for another of my \u201cBiochemistry 101\u201d segments.<\/p>\n<h2 style=\"text-align: center;\"><span style=\"color: #3366ff;\"><strong>Biochemistry 101: What Does Estrogenic Mean?<\/strong><\/span><\/h2>\n<p><a href=\"https:\/\/www.chaneyhealth.com\/healthtips\/are-eggs-bad-for-you\/professor-owl\/#main\" rel=\"attachment wp-att-3399\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-medium wp-image-3399\" src=\"https:\/\/www.chaneyhealth.com\/healthtips\/wp-content\/uploads\/2019\/04\/professor-owl-300x270.jpg\" alt=\"professor owl\" width=\"300\" height=\"270\" srcset=\"https:\/\/www.chaneyhealth.com\/healthtips\/wp-content\/uploads\/2019\/04\/professor-owl-300x270.jpg 300w, https:\/\/www.chaneyhealth.com\/healthtips\/wp-content\/uploads\/2019\/04\/professor-owl.jpg 365w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a>Let\u2019s start at the beginning with what polyphenols are. They comprise a diverse group of compounds with these common features.<\/p>\n<ul>\n<li>If you look at their structures, they contain multiple rings (A chemist would tell you they have more than one phenol group, hence the term polyphenol. But that terminology is only useful if you are a chemist).<\/li>\n<\/ul>\n<ul>\n<li>They are found in plants. Specifically, they are found in fruits, vegetables, herbs, spices and beverages (coffee, tea, and cocoa, for example).<\/li>\n<\/ul>\n<ul>\n<li>They have antioxidant properties.<\/li>\n<\/ul>\n<p>Types of polyphenols include flavonoids, phenolic acids, lignans, and stilbenes. I mention this only because soy isoflavones, which I will talk about later, are flavonoids.<\/p>\n<p>Some of these compounds have structures that resemble estrogen. If they bind to estrogen receptors and have the same effect as estrogen in cultured human cells, they are said to have \u201cestrogenic properties\u201d.<\/p>\n<p>That\u2019s why you see blogs warning about foods and herbal ingredients we should avoid because of their \u201cestrogenic\u201d properties. Some of these blogs are written by people with \u201cDr\u201d on front of their name. But they aren\u2019t biochemists and don\u2019t know what biochemists know.<\/p>\n<p>Let\u2019s dig a little deeper. Here are some of the complexities that most bloggers either don\u2019t know about or ignore.<\/p>\n<ul>\n<li>There is more than one kind of estrogen receptor.<\/li>\n<\/ul>\n<ul>\n<li>Different estrogen receptors have different effects in the cell. For example, some estrogen receptors activate pathways that increase cancer risk. Other receptors activate pathways that decrease cancer risk.<\/li>\n<\/ul>\n<ul>\n<li>The same estrogen receptor can have different effects in different cell types. That\u2019s why estrogen replacement therapy reduced menopausal symptoms and post-menopausal bone loss AND increased cancer risk in other tissues.<\/li>\n<\/ul>\n<h2 style=\"text-align: center;\"><span style=\"color: #3366ff;\"><strong>The Estrogenic Myth<\/strong><\/span><\/h2>\n<p><a href=\"https:\/\/www.chaneyhealth.com\/healthtips\/does-soy-increase-breast-cancer-risk\/breast-cancer-soy\/#main\" rel=\"attachment wp-att-2319\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-medium wp-image-2319\" src=\"https:\/\/www.chaneyhealth.com\/healthtips\/wp-content\/uploads\/2017\/05\/breast-cancer-soy-226x300.jpg\" alt=\"breast cancer\" width=\"226\" height=\"300\" srcset=\"https:\/\/www.chaneyhealth.com\/healthtips\/wp-content\/uploads\/2017\/05\/breast-cancer-soy-226x300.jpg 226w, https:\/\/www.chaneyhealth.com\/healthtips\/wp-content\/uploads\/2017\/05\/breast-cancer-soy.jpg 297w\" sizes=\"auto, (max-width: 226px) 100vw, 226px\" \/><\/a>A couple of weeks ago I talked about \u201cThe Soy Myth\u201d, specifically the myth that soy isoflavones increase breast cancer risk. That myth was based on the observation that soy isoflavones have estrogenic properties and a simplistic interpretation of what that means. But in fact, soy isoflavones:<\/p>\n<ul>\n<li>Are found naturally in most soy foods unless they are highly processed.<\/li>\n<\/ul>\n<ul>\n<li>Bind strongly to the estrogen receptors that decrease cancer risk.<\/li>\n<\/ul>\n<ul>\n<li>Bind weakly to the estrogen receptors that increase breast cancer risk.<\/li>\n<\/ul>\n<p>In contrast, estrogen:<\/p>\n<ul>\n<li>Binds strongly to the estrogen receptors that increase breast cancer risk.<\/li>\n<\/ul>\n<ul>\n<li>Binds weakly to the estrogen receptors that decrease breast cancer risk.<\/li>\n<\/ul>\n<ul>\n<li>Soy isoflavones compete with estrogen for binding to the receptors that increase breast cancer risks. This helps protect breast cells from the cancer-promoting effects of estrogen.<\/li>\n<\/ul>\n<p>So, it is true that soy isoflavones bind to estrogen receptors, but on the balance, you would predict that soy isoflavones decrease, rather than increase breast cancer risk.<\/p>\n<p>The key word here is \u201cpredict\u201d breast cancer risk. If you are a woman, you don\u2019t want a prediction, you want to know one way or the other.<\/p>\n<p>That\u2019s why multiple human clinical studies have been conducted to determine the effect of soy foods on breast cancer risk. As I told you two weeks ago:<\/p>\n<ul>\n<li>Some studies showed no effect of soy consumption on the risk of getting breast cancer or breast cancer recurrence if you have previously had breast cancer.<\/li>\n<\/ul>\n<ul>\n<li>Other studies found that soy consumption reduced the risk of breast cancer occurrence and recurrence.<\/li>\n<\/ul>\n<ul>\n<li>No studies found that soy consumption increased the risk of breast cancer occurrence or recurrence.<\/li>\n<\/ul>\n<p>So, for soy the answers are clear.<\/p>\n<ul>\n<li>Yes, soy isoflavones have estrogenic properties. That is a fact.<\/li>\n<\/ul>\n<ul>\n<li>No, soy consumption is not associated with an increased risk of breast cancer. That is a myth.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/www.chaneyhealth.com\/healthtips\/maximizing-polyphenols-benefits\/grape-polyphenols\/#main\" rel=\"attachment wp-att-3405\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-medium wp-image-3405\" src=\"https:\/\/www.chaneyhealth.com\/healthtips\/wp-content\/uploads\/2019\/04\/grape-polyphenols-198x300.jpg\" alt=\"grape polyphenols\" width=\"198\" height=\"300\" srcset=\"https:\/\/www.chaneyhealth.com\/healthtips\/wp-content\/uploads\/2019\/04\/grape-polyphenols-198x300.jpg 198w, https:\/\/www.chaneyhealth.com\/healthtips\/wp-content\/uploads\/2019\/04\/grape-polyphenols.jpg 281w\" sizes=\"auto, (max-width: 198px) 100vw, 198px\" \/><\/a>The situation with resveratrol is similar:<\/p>\n<ul>\n<li>It is found naturally in grapes and many other fruits.<\/li>\n<\/ul>\n<ul>\n<li>It has estrogenic properties.<\/li>\n<\/ul>\n<ul>\n<li>Cell culture experiments show that it activates pathways that reduce cancer risk.<\/li>\n<\/ul>\n<ul>\n<li>Animal studies predominantly show that it reduces cancer risk.
