Colonizing a planet: how much food would we need to bring?

Assuming that

• the planet is 20 light years away (so back and forth trips would be impractical)

• we have no clue whether there is any edible life forms on the new planet

• hibernation (freezing/thawing etc.) of our bodies isn't invented

• we carry 100 people

• The ship can travel up to 1/2 the speed of light

I know that in order to maintain a good gene pool, we will need at least 100 healthy people, who may grow old during the journey and have their kids (extra mouths to feed) to keep the generations going. Even if it is high energy food, people need to eat a lot and drink a lot.

About how much would any space colonists need to bring?

Would we need to balance between space craft fuel and food for the crew?
