My only thought is that they counted a shipment of water in there. 1 L = 1 kg. 2-3 liters per day consumption seems to be typical. So now you are down to 3.6 kg of food per day.
This page [nasa.gov] says:
2.5 kg from 3 meals per astronaut. Bump water consumption to 4 L per day and everything is accounted for!

Yeah that could be the difference, but it would be be rather misleading. Water is heavily recycled precisely for that reason. Even urine is reprocessed into drinking water!
