I don't know when to start, estrogen seems to be a negative word in our minds. Recently there have been rumors that "propolis contains estrogen causing cancer". Is this true?
The Propolis Professional Committee of the China Bee Products Association issued a statement saying that propolis contains hormones that can cause breast cancer. There is no scientific basis. So, is there any estrogen in food such as propolis? Wang Hao, an associate professor at the School of Food Science and Technology of Tianjin University of Science and Technology, said that foods that directly contain human estrogen are almost non-existent. More often, some foods have an estrogen-like effect. When estrogen and estrogen receptors are combined, estrogen will act. Many substances in food are very close to the structure of estrogen. They can also have weaker binding to estrogen receptors. This combination can also promote the metabolism of estrogen, so it is called estrogen-like effect. Such foods include soybeans, pollen, Bupleurum, Eucommia in traditional Chinese medicine, and some bee products.
In fact, there are many precautions for regular estrogen supplementation, including the time of supplementation, the type of supplementation, the amount of supplementation, etc., which need to be determined after evaluating the whole body condition. If a large amount of estrogen is used for a long time, it may cause adverse consequences, and even induce thrombosis, breast cancer or endometrial cancer. The type and measurement of estrogen in health products are unknown, so it is recommended that female friends, especially elderly women, should be cautious when choosing health products. Don’t blindly listen to the advertisements of some products, let alone follow suit.
