It keeps getting reported that many here in the UK are tossing out food.Buying stuff and it goes out of date.One programme had a food economist call at a couples home and show them how to avoid this.
Also careful shopping.Not buying from the one supermarket.We have German (EW you will know them Lidl and Aldi) where food is cheaper.To begin with people were wary but many have swung to these discount supermarkets.
I tend to buy the best quality I can,,wherever I judge it to be.In season locally we have veg and fruit.Soon my own tomatoes apples and plums.Redcurants blackcurrants.
Potatoes grown at a neighbours far,Leeks and carrots.
As a young wife I never wasted food.Now I admit to having done so a few times..and felt bad about this.On reflection I think it was bad planning believing the family wanted choice and trying to be "a good provider" .this is since they were adults.I strive to waste no more...Cant say I did it to extremes but I did go off the rails...
