Las preguntas que las lectoras nos plantean de verdad.

What are endocrine disruptors in simple terms?
They are chemicals that interfere with the body's hormone system. The Endocrine Society and the WHO and UNEP define them as substances that change how hormones are produced, released, transported, or broken down. Because hormones act at very low levels, even small interference can in theory matter, which is why these compounds get studied closely. Common examples include BPA, phthalates, PFAS, and parabens.
Should I be scared of endocrine disruptors?
No. Fear is not a useful response, and the honest scientific position includes real uncertainty. Exposure is widespread and documented by CDC NHANES biomonitoring, but documented exposure is not the same as documented harm at everyday levels. Dose, timing, and life stage all shape risk. The sensible approach is steady, low-cost reduction during the most sensitive windows rather than alarm.
Who is most at risk from EDCs?
NIEHS points to the developing fetus, infants, and children, along with pregnancy and puberty, as the most sensitive windows. Hormones direct development during those periods, so interference can have a larger effect than the same exposure would in a healthy adult. If you are pregnant or caring for young children, focusing reduction efforts there gives you the most benefit for the least effort.
Does BPA-free mean a product is safe?
Not necessarily. 'BPA-free' only means the specific compound bisphenol A is absent. Manufacturers often substitute related bisphenols such as BPS or BPF, and a 2015 Environmental Health Perspectives review found these have estrogenic activity similar to BPA. The stronger label to look for is 'bisphenol-free' or 'no bisphenols'. For more detail, see our BPA pillar.
What is the single most effective thing I can do?
Stop heating food in plastic. Heat increases how much chemical migrates from plastic into food, so microwaving or storing hot food in plastic is the exposure most worth avoiding, and changing it costs nothing. After that, switch to glass or stainless for hot and acidic foods, filter your water, and reduce canned food. Our microplastics and PFAS pillars go deeper on each.
