>I was intrigued by the term 'edible food like substances'
>verses FOOD
Though I'd sometimes question the use of 'edible' for some of them!
From my quick scan of the article, that was one of the points I thought was most important: out bodies were made to eat real foods, not substances created in a lab, or isolated/concentrated extracts of real foods and isolate nutrients (which are more and more being shown to be harmful...like vitamin A and beta carotene in supplement form). And I think that's important not just from a health persepective, but from a weight perspective, since our bodies know what to do with real food, and since they are better nourished on high-nutrient-density foods, which many 'real' foods are (vs the higher-calorie, nutrient poor 'fake' foods) our appetites are better controlled with real foods.
Often, when I go to the 'regular' grocery store, before I get to the produce section, I'm overwhelmed by the displays of 'stuff' that people put in their bodies that are far from food. And those are the things that often are the most well-displayed and eye-catching (obviously, 'crap' has a higher profit margin than real foods).
I remember going to one grocery store for the first time, and soon realizing that everything I wanted seemed to be hidden behind a post or another display. I checked out my theory when hitting the peanut butter aisle, and wouldn't you know it, the Smucker's Natural PB was behind another post! LOL! (Guess they figure people looking for the healthier options are willing to hunt for them, while those who buy junk and non-food foods need to be enticed more?)
