The Bob's Red Mill bag says - ALUMINUM FREE and Not Processed with Chemicals, does that mean the Arm & Hammer may have those things?
I found nothing by googling on this subject and I am very very curious, thanks!
i found an article here the describes how baking soda is often made. so it looks like it might not be just a marketing ploy because baking soda is often manufactured with the use of chemicals. but wow the Bob's Red Mill baking soda looks to be expensive.....
this link contains an excerpt from an email from Dwight about their Arm and Hammer bkg soda.
Sorry, to break the news to all the Bob's Red Mill or Arm & Hammer fans. For all the hype about natural or chemically made Sodium Bicarbonate (Baking Soda) it real makes no difference. None are 100% PURE. They all have trace elements of one type or another.
Attached you will find the Tech Info provided by the manufacturer, "Natural Soda" of the Sodium Bicarbonate, used and packaged by Bob's Red Mill. As you can see the the baking soda can contain 2-ppm Arsenic, 5-ppm Heavy metals (that would be lead, Chromium, etc.), 150-ppm Chloride, 150-ppm Sulfur compound. That would translate a possible cummulative 0.0307% impurities total or 96.93% Sodium Bicarbonate.
Copy and paste link attached to verify.
So, is a trace amount of aluminum better or worse then trace amounts of arsenic and heavy metals.
Use facts not emotions, I remember the days that medical experts were saying that olive oil was bad for you.
Moderation of all is key.
