Interesting.I'm allergic to mold and I react badly to citric acid. Found this on google Citric acid and mold allergy | AAAAI
"The process by which commercial citric acid is made does involve aspergillus niger. However, the mold is filtered from the final product, and this product is treated with calcium hydroxide to yield calcium citrate, and citric acid is then formed by treatment with sulfuric acid."
Didn't Ray mention that sulfuric acid was contaminated with lead during the manufacturing process? I don't have any problem with phosphoric acid only Coca Cola. Wish there was another soda without citric acid, kind of tired of coke now...
Also, I think Ray said that modern day vitamin C is contaminated with a heavy metal (lead?) during the manufacturing process. Thanks.
