I don't know anything about the Live Earth stuff--the Hicks web site refres to it like it is a single product, and they feed it to their dairy cows--but the Live Earth web site that Hicks links to does show several different products that are soil additives, so I dunno about that. But the Fossil Shell Flour is definitely food grade DE. If you google Perma-Guard Fossil Shell Flour, you'll get a manufacturer's website which will tell you how their DE is the best (which you'd hardly expect them to say theirs was okay, but there are better ones out there...)--something about how theirs comes from fresh water sources, so much better than salt water sources, blah blah. But its the same brand I've been using for the last two years with apparently good results, except this time I picked it up in a parking lot in Ann Arbor instead of halfway to Detroit.
