Out of curiosity, I looked up a site that explained the various methods of producing baking soda. None of them involve aluminum. For this reason, I am comfortable with any brand of baking soda as long as it is not made in China. I would then be concerned about lead, melamine, or other odd contaminants.
http://www.madehow.com/Volume-1/Baking-Soda.html Am I missing anything? Why would one choose to disbelieve one maker, yet believe another? Don't they all have the same interests? That is, producing a product for which they can sell at a profit? Making sure the product is what they say it is so that they maintain their reputation? Now, baking soda is sometimes confused with baking powder, a totally different product. Some baking sodas are made with aluminum salts. Is this causing some confusion with baking powder?
