I like to imagine it went something like this:

Five women were sitting around a table eating sprouted whole grain scones, talking about the latest in health scandals. Martha turned to Jody and with a sly smile whispered into Jody’s perfect curly-q ear, “Did you know baking powder has aluminum in it? I bet Janice used baking powder in her scones! We’re all going to get Alzheimer’s now. Thanks a lot, Janice.”

Jody squinted her eyes and gave it a bit of thought, and turned to the manicured Steffi and whispered, “Did you hear? Baking powder has aluminum in it!”

Steffi, not quite sure what to make of this information, leaned over and whispered to Maggie, “What’s the deal with baking soda containing aluminum? I thought that was BAD!” And Maggie, ever the first to know of shameful health trends, stands up, flips over the table and says, “YOUR BAKING SODA HAS ALUMINUM IN IT, JANICE! WE WILL NOT BE LUNCHING HERE TODAY.”

Then all the ladies, except for poor, confused Janice, march out the door and into their nearest Whole Foods to find aluminum-free baking soda.
