Diatoms are a microscopic organism that exudes silicon dioxide (AKA: GLASS, you fucking fat retards, holy hell!). Normally, they're harmless. In fact, they're a cool part of the ecosystem. Our skin is an amazing organ, and you wouldn't care about sticking your hands in Diatomaceous soils, but earthworms and other small organisms will be sliced to bits. After all, it's filled with amazingly small bits of glass. That's why you'll see it used in certain gardening projects.  But what happens when you eat it? All that soft tissue on your throat, stomach, and intestines is closer to the skin of an earthworm, and yes, it's probably going to be cut up in a bunch of little slices. I can't even begin to think of how retarded the first person must have been to think, "Oh, glass? That's a great thing to eat for health!"
