Inspired by slimemoldtimemold’s blog series “A Chemical Hunger,” I have these four previous posts:

1. Are Processed Food and Environmental Contaminants the Main Cause of the Rise of Obesity?

2. Livestock Antibiotics, Lithium and PFAS as Leading Suspects for Environmental Causes of Obesity

3. How Rising Anorexia Can Go Along with Rising Obesity: Both Can Be Caused By Environmental Contaminants

4. How Lithium May Have Led to Serious Obesity for the Pima Beginning around 1937

Today I want to make the simple point that there are probably some market opportunities in helping people deal with these possibly obesity-causing environmental contaminants. First, people will be interested in tests for livestock antibiotics, lithium and per- and polyfluoroalkyl substances (PFAS) in drinking water. Second, people will be interested in knowing that uncontaminated water was used in food production. Third, people will be interested in bottled water or flavored sparkling water certified free of these contaminants. You can see what a fan I am of the latter from “In Praise of Flavored Sparkling Water.” (I would also like to know that the cans are BPA-free. Waterloo and La Croix brands are BPA-free, but information on this can be hard to find on other brands. Note that there are many other sources of BPA you should probably be worrying about more: liquids packaged in plastic and many types of processed food.)
