Heavy Water and Health

Ok, here is something that caught my interest. An article on the health benefits of heavy water or also known as deuterium (an isotope of hydrogen consisting of one proton and one neutron).

The first link I saw was pointing to an article in today's Telegraph in the UK, but that article was no longer available. I wonder why? Was it a hoax? Were there some security issues?

You see, heavy water is the material you can use to slow down neutrons to thermal energies that can be used to split U-235 (nuclear fission). Canada's nuclear power program uses heavy water as a moderator with natural uranium.

If you don't use heavy water, you must enrich the U-235 which is expensive and has nuclear proliferation issues connected. The Nazis tried to use heavy water (made in Norway) in their effort to develop the atomic bomb.

The linked article above is one of the semi-recent articles I found on the subject. Interesting that there is an Iranian connection.
