Food Grade hydrogen peroxide

I hear lots about how hydrogen peroxide of how it cures so much and you have to use food grade because the other stuff is full of junk. 
does anyone experience or know much about this. 
I started to take a few drops in some distilled water every day and it seems like I haven't been getting sick.  Maybe it is all the fresh raw goat milk and garden veggies I have been eating too.  but does anyone know much more about it.
