In this segment, Dr. Isaac Eliaz exposes the growing dangers of plastic packaging. Each year in the United States, nearly 90 million plastic bottles are purchased, burdening both the environment and your health. Certain chemicals contained in these plastic containers—including bisphenol-A (BPA) and polyvinyl chloride (PVC)—act as xenoestrogens, or substances that mimic estrogen in the body. They seep into your beverages during normal use, and are especially potent at high temperatures.
