"The estrobolome is really the secret controller of your estrogen… while I thought it was more my ovaries or my fat cells or my adrenal glands, the estrobolome plays a vital role in the regulation of estrogen." ~Jacqui Bryan Today on Beating Cancer Daily:· The estrobolome is a collection of gut bacteria that directly regulates estrogen levels in the body· Gut dysbiosis can lead to excess estrogen being reabsorbed, increasing risks for breast cancer and other estrogen-dominant conditions· Classic blood tests may not reveal problems with estrogen metabolism, while functional medicine stool, urine, and zonulin tests offer deeper insights· High-fiber diets help trap and eliminate used estrogen, preventing it from being reabsorbed into the system· Probiotics, especially those containing Lactobacillus acidophilus, can reduce the harmful enzyme that releases estrogen from the gut back into the body· Cruciferous vegetables such as broccoli and kale support the liver's ability to package and remove estrogen efficiently· Estrogen dominance is linked to a wide array of health risks, including breast cancer, endometriosis, cardiovascular disease, and autoimmune issues· Simple lifestyle changes like clean eating, regular exercise, increased fiber, and gut-focused nutrition can empower individuals to manage their hormonal health Connect with Jacqui Bryan: Jacqui Bryan 2025 People’s Choice Podcast Awards Best Health Series FinalistRanked the Top 5 Best Cancer Podcasts by CancerCare News in 2024 & 2025,and #1 Rated Cancer Survivor Podcast by FeedSpot in 2024 to 2025.
