A third of food thrown away.  

Wow, that is a big waste. In my family we hardly ever throw food out. I have a family of 5 so the meals I make there is normally leftovers. So what I do is about every third day we have leftover night. I pull all the leftovers out from the past three days and everyone picks what they want. When I do this I never end up throwing any food out.

For me, I cook food that is enough for everybody in the house and if someone is not satisfied he can worm leftovers from the fridge. It is not good for people to throw food away and if you see that you have made food which is going to waste then it is better you pack it well and take for the street families who are starving out there. My mother thought us when we were young that if you throw food, you throw it with all your luck. Blessed is the one who gives than the one who receives.

I do the same as you but I also have a goat who cleans up what the dog doesn't...problem is he likes the compost too. LOL.
I take little notice of "best before" dates and try to plan my meals according to what needs to be eaten first.

Well, we have four kids and a dog, so there is very little food waste in our house. Sometimes I would cook too much meat, but that wouldnt get wasted because it is always used for sandwhiches or paninis in the evenings. Or during the night when my husband is up and about and gets the munchies!!!!!!

when someone gives me food at home or at work..i take it and throw it away later..i take it just to be nice..but out it goes before it can be eaten..food is so cheap..why eat something you don't think will be good for you?

I do try, but things just get away from us sometimes. It happens. But I'd rather throw away spoiled food than take a chance on eating something that might make me sick. And I don't believe in giving my pets human foods - onions and garlic are very bad for cats and I don't think the roomie can cook without garlic.

I hate wasting money and food. It is not a good habit. Alough someone can afford it, there are still many poor people who get little food everyday. In my country, it often happend. When someone does not like the food and eat little, they just leave it on table. I really do not like that.

i will estimate how can i eat...
not more than that i will order..

simply buy a bit less than what you feel like buying when you shop for groceries. We are not in walking distance of the supermarkets and so I have to add we plan our shopping so that my hubby does not do that more than twice a week. We have a little pantry added to the kitchen and put all the canned goods there and we have quite a big combined freezer and fridge. Sometimes so its a temptation to buy more than what you really need.
We also keep some things in the fridge and pantry for emergencies when you simply forget the milk or other items.

As I come from the background of a WW II Refugee family from what is now Poland, Silesia, waste of food was unknown to me at home. Okay sometimes bread turned mouldy in the summertime but very rarely. Dry bread was used for cooking, and there was a non written rule I still observe now in my own 40s, when you see something that is expired first open and test and only throw away when its really rotten. I know a lot of people who will just look at the sell by date, and say, this is one or two days over the date so it goes out without looking first. But I always open milk products and other foods first and see what is still edible when it once in a while happens here.

I also like cooking from scratch and that saves money, too.
