The contents of your fridge reveal a lot about your life, your family, your job and your standard of living. Whether it's milk, eggs, cake or meat, the food inside tells a story.

Three quarters of homes around the world have a fridge and about one in five have a freezer, according to market research firm Euromonitor - and as living standards rise so does fridge ownership.

Readers told us what they keep in their fridges - and it's not always food.

Kathryn Riepl, South Island, NZ: I have two sons, Henry and William, aged nine and seven, who are mad on comics. I opened up the fridge to find this yesterday (see above). It cracked me up.

Sanya Amnartpluk, Thailand: Our freezer is full of expressed breast milk in bags. There is enough there to feed our baby until he turns one. [Note: The NHS advises breast milk can be frozen for up to six months.]

Amanda-Jayne Carr, London, UK: My fridge is full of lots of lovely bacteria. I'm a scientist investigating macular disease and loss of vision. I also keep eye cells in a freezer at a temperature of -80C. That freezer texts, phones and emails me with updates at all times of day and night. It's a cold stalker.

Ruth Kendall, UK: I work for a charity and this photograph was sent to us by our partners in Gaza, the Near East Council of Churches, who help mothers prepare more nutritious food for their children. Here, a young boy shows the inside of his family's fridge. He lives in Shijaia, one of the largest, oldest and most crowded neighbourhoods in Gaza, heavily bombed during the summer conflict.

Doris Enders, Goa, India: Nowadays I'm lucky to have a "normal" fridge but the ice man reminded me of earlier times when it was necessary to buy ice and put it in a box to cool my food. When I don't have a fridge I buy only the food I need for the day.

David Murray, Manchester, UK: This sums up our modern life - choose what you want in the fridge or freezer.

Dennis Relojo, London, UK: I feel sad to see that my fridge is not full but then I remember that I grew up in a slum in Manila in the Philippines, where my family did not even have reliable electricity, running water or a cooker. And then I suddenly realise that this fridge is indeed a luxury.

Rob Boler, UK: If I hadn't seen your feature on the BBC website, these unopened photographic films would have remained in my fridge for another 15 years. They are long-forgotten relics of the time when I did wedding photography in the 1990's. I found film to be a tedious, inefficient, impractical medium, and I haven't the slightest regret in seeing its demise.
