Exploration of Hyena Anatomy and Hormonal Impacts

In this episode, my guest is Dr. Shanna Swan, Ph.D., professor of environmental medicine and reproductive health at the Mount Sinai School of Medicine. Dr. Swan is the world’s leading expert on the harmful impact of chemicals in our food, water, cosmetics, and various household and consumer products on our hormones, and the consequences for fertility and overall reproductive health. She explains how exposure to phthalates and other endocrine disruptors adversely impacts fetal development, puberty, and the adult brain and body. We discuss the global decline in human fertility due to disruptive environmental toxins, such as pesticides, and certain foods and beverages we consume.

We discuss practical strategies to minimize exposure to harmful chemicals, such as phthalates, bisphenol A (BPA), BPS, and PFAS. This includes reducing disposable plastic use, making healthier food preparation, consumption, and storage choices, and selecting personal and household products that don’t contain harmful toxins. This episode allows you to assess your risk of exposure to endocrine disruptors accurately and empowers you to take control of your hormone health and fertility.
