Personally, I think it is a sin to waste food, especially when there are many Men, Women, and Children in the world today that will go to bed tonight hungry.
I don't see a connection between the food I eat, store, or throwaway and the fact that someone else I can't reach with it is hungry. If I eat the rest of my sandwich, or I throw it away, it doesn't affect them either way.
Is the thinking that if I didn't waste food, then I'd have more money left over that I could then donate to those in need? The math works out, I'm sure, but the same could be said of taking a different route to work because it saves you five minutes a day. Sure, if you add them all up, you come out with hours of extra time, but since you only get them in five minute increments, you never notice it.
I'm sure I'm tainted by growing up with plenty of food, and I don't lack for it now. There was a few periods of my life when I didn't always have the quality of food available to me that I would have preferred (due to funds) but I don't think I can ever recall going hungry because I just didn't have access to food. Maybe if I'd ever been truly hungry I would feel differently. But I see wasting food as simply wasting the money that paid for it. I pay $1 for a hamburger, eat 70% of it, and throw the rest away. I just chucked 30 cents. No biggee. To someone else it might seem like a biggee, but I can't give it to them so I don't see what difference it makes.
A bakery that has a policy of throwing food away when charity groups would happily pick it up and distribute it sounds wrong, but on the other hand if they gave it away, those that could buy their fresh products might choose not to. Then the bakery loses money and ultimately collapses. They can sell the products at a reduced cost, but those products then compete with their fresh ones, making them wind up with MORE day-old/reduced-price products.
I think there's more to this story than "it's terrible to throw food away". Food is money, it's an economic question as much as a nutrition one.
