Why Do Silica Gel Desiccant Packets Say DO NOT EAT When Silica is Added to Foods?

Silica is Actually Added to Foods, Yet Silica Gel Dissicant Packets Say DO NOT EAT

I came across a comment about Rachael Ray saying that everyone should make their own taco seasoning mix instead of using store-bought packets, because they are full of sodium and they contain silica, the same stuff found in those ant-desiccant packets that say DO NOT EAT.
