Food consumption: NONE costs 100
Food From Population NONE refunds 40

Is this combination supposed to work?

no food is a strategy you could play without food consumption none, just saying..

Also the developers might consider excess food production to counter into trade goods at some point.. *hinthint devs*

I didn't say it would not be a strategy, but rather that if one chose no food consumption the zero food production is an obvious choice, but also that it makes the total points spent = 60 which is 10 less than =50% food consumption which costs 70. I do understand that 50% food consumption combined with bonus food production is a viable tactic, but I don't think it is as good as the no food option for 60.

OK I just tested it. 50% food consumption with 50% food production and 50% population growth results in faster growth than the zero food combination and only 1 or 2 farmers are needed to maintain a planet at max capacity. While it does cause a player to endure more penalties and gives fewer options on how to play the game it is viable. I think the -50% food consumption should be reduced by 10 or 20 cost however.

That make more sense, I wasn't sure where the issue was with your original post :)
