Change it to "30 stored manufacturing" boost so you can build your first level 1 building in 1 turn.
That screws over factions with the Colonizer trait thou. 
The solution here is rather simple: Don't take it until one will have at least 6 units of food on each planet (easily doable via techs or trade resources). Then send out all of your colony ships with only .5 or 1 pop unit.
In fact, as I check, it should only take 1 +1 food tech or 1 +1 food trade resource. Since this is a third level Benevolent trait, it's not like one is going to get it right away anyway. So just wait a spell.
Alternatively, send out an extra colony ship or transport (if you have them) behind it and pick up the surplus pop that way. Though, as I said, by this time one really should have at least one tech that gives +1 food.
(PS: As I look at the tech tree, and I see which techs give +1 food, this is another reason NOT to have "collapsible specializations". 
)
