Page 14 of the rules under Exile says
The exiled player cannot spend food tokens to increase his action die results, but may play food cards to increase an action die result by 1 for each food card played rather than carrying out the effect listed on the food card
The literal reading seems to imply I can only increase a die by 1 for even a Food 2 card. Is this true or can they increase a die twice or two dice once each with this sort of card?
