Expendable resources

Food is one of the only resources that's considered wasted if not used. Most other resources, from emotional ones like love to abstract concepts like time to physical things like money, are called wasted if used on the "wrong" outlets. Or, in the case of money and other tangible objects, if consumed in great quantity very fast. Food is a rare exception.

The psychology of food pictures

Now, I'm not knocking or judging people who like to share photos of everything they ingest. Posting food photos is your legal right as a citizen of Facebook, seeing as the Declaration of Internetdependence grants us the right to life, liberty, and the pursuit of indefinite "likes." So if you want to show everyone what you're eating, go right ahead. But I have to admit that I don't quite understand the motivation. When we share photos of our meals, is it in memorium of the food? Is it due to the desire for a communal meal with all of our friends and followers? Is it to make others jealous and/or hungry? Is it to offer people ideas for what they, too, can consume? I have posted a picture of a bottle of mead, and it was because I know a lot of people who have never heard of mead and I want to spread the word (or image) so they can experience its incredible majestic deliciousness themselves. I haven't grasped the overall reasons behind this practice, though.

Also, maybe taking pictures of what we're eating is sort of like a Level 2 Selfie. A selfie is "This is my face," while a food pic is "...And this is what goes INTO my face!" It's like a selfie, but more in depth.
