Fish on Friday | West Hunter
There are parts of Europe, Switzerland and Bavaria for example, that are seriously iodine deficient. This used to be a problem. I wonder if fish on Friday ameliorated it: A three-ounce serving size of cod provides your body with 99 micrograms of iodine, or 66% of the recommended amount per day.

Thinking further, it wasn’t just Fridays: there were ~130 days a years when the Catholic Church banned flesh.

population surveys indicate lots of people are iodine-insufficient even in the US or UK where the problem should’ve been permanently solved a century ago

Environmental Cancer? | In the Pipeline
And while I take the point that endocrine disruptors and the like need to be watched (and that we really do need to study these things more), I don’t see why the alarm bells need to be rung quite this loudly.

Summary | EWG's 2017 Shopper's Guide to Pesticides in Produce
Three long-term birth cohort studies in the U.S. suggest that pesticides are harming children’s brains. In these studies, researchers found that women’s exposure to pesticides during pregnancy, measured through urine samples, was associated with negative impacts on their children’s IQ and neurobehavioral development, as well as with ADHD [attention deficit hyperactivity disorder] diagnoses. Also, one of the studies looked at structural brain growth using magnetic resonance imaging and found that the gray matter was thinner in children the higher their mothers’ exposure to organophosphates, which are used widely in pesticides. I think that’s quite scary.

Bisphenol A (BPA)
Alternatives to BPA containers not easy for U.S. foodmakers to find: http://www.washingtonpost.com/wp-dyn/content/article/2010/02/22/AR2010022204830.html

Food is main source of BPA for consumers, thermal paper also potentially significant: https://www.efsa.europa.eu/en/press/news/130725
New data resulting from an EFSA call for data led to a considerable refinement of exposure estimates compared to 2006. For infants and toddlers (aged 6 months-3 years) average exposure from the diet is estimated to amount to 375 nanograms per kilogram of body weight per day (ng/kg bw/day) whereas for the population above 18 years of age (including women of child-bearing age) the figure is up to 132 ng/kg bw/day. By comparison, these estimates are less than 1% of the current Tolerable Daily Intake (TDI) for BPA (0.05 milligrams/kg bw/day) established by EFSA in 2006.

For all population groups above three years of age thermal paper was the second most important source of BPA after the diet (potentially accounting for up to 15% of total exposure in some population groups).

Among other key findings, scientists found dietary exposure to BPA to be the highest among children aged three to ten (explainable by their higher food consumption on a body weight basis). Canned food and non-canned meat and meat products were identified as major contributors to dietary BPA exposure for all age groups.

Food is a main source of DiBP, DnBP, and DEHP in consumers. In this case, consumers have very few possibilities to effectively reduce their exposure.

Reduction of chemical exposures was associated with a 13% (95% CI 2% to 22%) reduction in prevalent diabetes, compared with 40% resulting from an identical (25%) reduction in body mass index (BMI) in cross-sectional analyses.

Investigation of PM2.5 and carbon dioxide levels in urban homes. - PubMed - NCBI
measured in Alexandria, Egypt

The indoor/outdoor (I/O) ratios of the monitored homes varied from 0.73 to 1.65 with average value of 0.99 ± 0.26 for PM2.5, whereas those for CO₂ranged from 1.13 to 1.66 with average value of 1.41 ± 0.15. Indoor sources and personal activities, including smoking and cooking, were found to significantly influence indoor levels.

What is up with carbon dioxide and cognition? An offer - Less Wrong Discussion
study: http://ehp.niehs.nih.gov/1104789/
n=22, p-values < .001 generally, no multiple comparisons or anything, right?
chart: http://ehp.niehs.nih.gov/wp-content/uploads/2012/11/ehp.1104789.g002.png
- note it's CO2 not oxygen that's relevant
- some interesting debate in comments about whether you would find similar effects for similar levels of variation in oxygen, implications for high-altitude living, etc.
- CO2 levels can range quite to quite high levels indoors (~1500, and even ~7000 in some of Gwern's experiments); this seems to be enough to impact cognition to a significant degree
- outdoor air quality often better than indoor even in urban areas (see other studies)

the solution: houseplants, http://lesswrong.com/lw/nk0/what_is_up_with_carbon_dioxide_and_cognition_an/d956

except that environmental instability tends to be harder on more 'complex' adaptations and co2 ppm directly correlates with decreased effectiveness of cognition-enhancing traits vis chronic low-grade acidosis
