My post was a really bad joke. It is common for manufacturers to replace turmeric with yellow dye number 2.

It is a good example of how they take something healthy out of food and then replace it with something that is potentially carcinogenic to increase profits.

For example, most pickles in the United States use yellow dye number 2. The dye make it look like they added turmeric.

If there are batteries that use turmeric; I suspect that we will see the same thing. There will probably be companies that remove the turmeric and replace it with the dye to make it looks like it works.
