If you build several foreign offices, you'll increase your chances of getting a food drop at least once a day. Multiple times a day if you're lucky. This will allow you to reduce your dependence on farms and kitchens. You can either try to supplement your existing food production, or if you go crazy on the offices, replace it completely. (although it's not quite as "set it and forget it" as farms + kitchens are) Give them only one shift off, turn off all other job filters, and put in at least 3 desks for rapid point gain. If you max out the office, you can always remove laborers and assign them somewhere else.
