Healthy Environment and Endocrine Disruptor Strategies
HEEDS is a non-profit coalition of scientists dedicated to improving communication, coordination and collaboration in the field of endocrine disrupting chemicals (EDCs). HEEDS is developed by scientists for scientists. There are no membership fees. HEEDS works to move EDC science forward, increase collaborations across scientific disciplines, communicate results and improve policy and regulations.

- Op-ed: To curb chronic disease in Americans, the FDA needs to assert regulatory control over toxic chemicals in our foodby Frederick vom Saal et. al on May 15, 2025 at 11:08 am
Editor's note: This op-ed was written by Frederick vom Saal and 15 co-authors. The full list of co-authors, their affiliations, and their contact information is included below. As senior environmental health researchers and physicians, we are united in our concern about the escalating prevalence of chronic diseases in the United States. To stop the increase of these chronic disease epidemics, it is essential to change the U.S. Food and Drug Administration’s current lack of regulatory oversight of toxic chemicals in food.

- Webinar: Communicating about EDCs & health: why words matterby Sarah Howard on May 9, 2025 at 6:22 pm
In this July 8 webinar, Drs. Kevin Elliott and Laura Vandenberg will discuss the range of ways in which scientists can frame and present information on research findings. For example, framing an EDC-related health outcome as a disease or disability can help to focus public attention on hazards of toxic chemicals and promote action to protect human health. At the same time, this framing can be used to stigmatize and harm individuals and communities. The speakers will share a range of strategies available to researchers to communicate responsibly and effectively. Sponsored by the Collaborative for Health and Environment (CHE).
