Help with diatomaceous earth concern

Greetings everyone,

If I am not posting this right plz forgive me I am new at posting. I watched a video done by Tony who is saying how bad silica and diatomaceous earth is for the body...how it switches off your dna communication and loads you up with heavy metals.
I had awful knee pain and left hip pain two months ago and started taking food grade DE and all my pain is gone!! And I am sleeping better than ever. I had spent a fortune trying everything natural under the sun to sleep.

Can someone watch this video and comment on it for me? I am so bummed I am getting incredible results with DE but will it give me cancer in exchange?
