Many women eat healthier during pregnancy, but that may mean whatever version of 'healthy' is trending in any given year. Sugar-free, low-fat, gluten-free, paleo, organic, it all has proponents, it all has suspect epidemiology papers claiming it should be a reason to buy some New York Times bestselling diet book built around it.

In 2016, The Frank R. Lautenberg Chemical Safety for the 21st Century Act amended the Toxic Substances Control Act (TSCA) and created a mandatory requirement for EPA to evaluate existing chemicals using transparent methodology and risk-based assessment. Not simplistic epidemiology.

This was actually a good thing. We want to make sure people are still safe as new data arrive and since they were using science and not statistical correlation, we could have confidence in the results.

The International Agency for Research on Cancer (IARC), a United Nations epidemiology group headquartered in France, could be in ethical hot water again over the claim by a Ramazzini Institute leader that seems to know in advance that IARC will consider aspartame a carcinogen - a designation which leads to automatic warning labels or even bans in places like California, which under Proposition 65 turned over its science to IARC last century.

Alcohol is a legitimate class 1 carcinogen that is prized by most of the world. While claims of health benefits were always suspect epidemiology, so were claims that even a glass of wine during pregnancy would cause birth defects. The dose still makes the poison but as modern science journalism became more advocacy-driven, claims that any dose is probably a poison became common.

America doesn't have a science literacy problem, at least in a relative sense. Though only 29 percent of American adults can demonstrate good science literacy, that is still enough to be number one in the world.(1)

A new paper notes that they can detect per- and polyfluoroalkyl substances - deemed by environmental activists as "forever" chemicals because they persist from to eight years - in 42 samples of food packaging. Like food bowls that are compostable and sustainable and better for the environment than plastic.

Ironically, this new detection, and resulting scare, happened because consumers demanded alternatives to plastic after environmental public relations campaigns saying all the fish were dying. Most foods will not be safe in paper(1) unless you eat them right away. And yet the alternative is now claimed to be worse than the thing they wanted replaced.
