They have links (as always) to a few supposedly scientific studies on the matter, one of them suggesting an effect against oxidation. I don't really understand how grounding would help against that, I would even think that it would make things worse if anything. It does make some sense though that we might have adapted through evolution to being grounded, with our ancestors walking barefoot and everything...
