About a week ago I saw Garrett Reisman give a tour of the ISS. It was a commentary on the daily life of an ISS inhabitant. The thing that caught my attention is that there is 'no refrigeration' where they eat, which is at the Russian side. They can hydrate and heat their food, but, albeit, and not to deamean Russian human space survival, but, there really IS 'NO' refrigeration when it comes to consumables aboard the ISS. They could have fruits and vegetables with every meal if they did.

My question is, why not? I know that there are cryogenics involved in the other labs, meaning that they have to keep experiments at below zero. I've seen many astronauts that are about to leave the ISS take those cryogenic 'cartridges' out from the walls so that shuttle can bring them back home. So why not have refrigeration when it comes to food or even 'iced' beverages. Consummables would go a long way, especially fruits and vegetables.

It would not only be a plus for the ISS, but for future space survival... moon, Mars.
