And most sugar isn't whitened with bone char. Just CANE sugar. Which is more expensive than beet sugar.
Most generic and store-brand products use beet sugar.
That said, the companies who are moving away from using HFCS (Whole Foods, Jones Soda, Trader Joes, Smart Soda) are starting to advertise that they use "pure cane sugar" so.... if you drink those named soda brands, there's a chance your sugar in your soda may have bone char.
As for the big, national brands, they still just use HFCS.
