In England and Wales we're throwing away 3.6m tonnes of food waste a year, which adds up to £9bn a year. A lot of it is due to over-buying food in supermarkets and then throwing out stuff because it's past its "best before" date, which isn't the same as the "use by" date. See the link on the right (Love Food, Hate Waste).
I'm old enough to remember post-war ration books. I might still have one somewhere. When food was rationed, most people ate a healthy diet because it was carefully balanced by nutritionists. Many more people were doing physical work too, so they burned off the calories from saturated fats and sugar. When I worked on a farm, my breakfast (after I'd already done a couple of hours work) was double-yolked eggs, bacon, sausages, fried bread, tea and toast and marmalade with butter. I weighed far less than I do now, and was far healthier.
Maybe it's time to bring rationing back? It would make people think twice about throwing good food away, while ensuring the low paid ate properly. You could favour British producers and save a fortune on food-related health care. Yes, I know it won't happen, but I can dream.
