Asteroids - Worlds that Never Were

Asteroids have a bad reputation as deadly rocks from space. They wiped out the dinosaurs and will be back for us. But that's only half the story. Ancient asteroids built the Earth. And they may have brought life to its barren surface. Asteroids will shape our future as much as our past. They are the perfect location for deep space colonies and could be the stepping stones that eventually send humans out into the cosmos. From icy worlds with more fresh water than Earth to flying mountains of pure metal, a hundred miles wide, scientists are striving to unlock their secrets. Could these enigmatic space rocks hold the key to how life in the Universe arises and is extinguished?

In this episode, they investigate whether we should really be giving up bacon and sausages, after new research suggested they're bad for us. The programme explores why eggs, for years demonised as unhealthy, are now firmly back in fashion and apparently now about as healthy as you can get. Could butter or dripping be next? Plus why white bread isn't necessarily as unhealthy as assumed.
