How can one send food, directly, to people who are in need?

I am asking this question on behalf of my girlfriend.
Does anyone know if there are ways, if any, to send food to, lets say, people in Africa directly?
There is of course the possibility to donate money to charity organisations, but she specifically wants to know if it can be done from one family to another family (in need).
Anyone has experience with this, or can lead us to websites or addresses that have information on this subject?
Help would be much appreciated!
