The film whatthehealth is now available on netflix... it's basically a film about the connection between diet, disease and the medical industry. It's quite an eye opener and shows how people are being manipulated into eating diets that are unhealthy in order to sustain pharmaceuticals and ensure they profit as result of people's ill health... here's the trailer...

Of course there's cowspiracy(also on netflix) too about the connection between diet and global warming....

if you're concerned about health or the environment you should at least check out the trailers then check the films out too.

Man is the most insane species. He worships an invisible God and destroys a visible Nature. Unaware that this Nature he’s destroying is this God he’s worshipping.
