We take the scientific method seriously. We also recognize that bias is inescapable, requiring us to stay on our toes to distinguish between quality research and other “stuff.” In addition, new information is always emerging on these topics. To help in this, we ask that you share concerns or alert us when you come across something that may increase our understanding or allow us to make more effective recommendations. When appropriate, we may alter action ideas to fit current knowledge. After all, we are committed to doing the best we can with always-incomplete information.
Researchers have studied almost all of the actions we promote, many of which have been strongly associated with improved personal, community, or environmental health outcomes. In the case of an idea like drinking mainly water rather than sugar-sweetened beverages, we can point to strong clinical and epidemiological evidence and general consensus among researchers. Other times there is less of a consensus, as with personally avoiding and protecting others from industrial chemicals that can mimic estrogen. In such cases we take a conservative approach to what gets into our bodies. Humans didn’t evolve consuming chemicals like bisphenol A (BPA). The evidence of its impacts on people appears complex, but various studies have indicated that it can harm things like fertility and food metabolism.
