I think the article or slide show was interesting, thank you for posting it

and had some points, but I also think that most of the food examples are not "tricking" people but rather offering fatty and unhealthy foods to the masses. I mean if you're going to eat buffalo wings or potato skins, well you pretty much know what you're getting.
There is a product out there that is supposed to be a "healthy snack" and at the moment the name of this product escapes me, but I remember looking at it because my boyfriend said he was shocked when he read the label and it was just as bad as a bag of chips. The packaging was green with a big "healthy" attitude with the look and feel and I literally saw people walk up, study the package, and buy it instead of the healthier snacks beside it just because of how it looked. They didn't read the label is my point. Okay, yeah that isn't responsible, but it also is a form of trickery from the company producing this stuff. Clearly it isn't healthy, why not just go get a bag of Doritos instead. At least with the Doritos, well you know what you're getting lol. The people who buy that product are buying a "healthy snack" because f the packaging. I did see one woman read the label, she quickly put it down and went to buy some baked chips which were healthier lol. But I read labels now...so when you actually take an interest in your food you tend to weed out a lot of the tricky products out there.
I think the other kinds of tricks are the availability of certain treat type foods. When I was a kid, going to an ice cream parlor was a little event. We didn't do it often, but you know it was fun and I mean a real ice cream parlor, not Baskin Robins. But now you can DRIVE THROUGH and get your ice cream and donuts all in one go! That is a bit sickening to me and you know I see people driving through and getting ice cream lol. It isn't special to me anymore. Even though I can't eat ice cream, unless it is vegan, I find it kind of sad and disturbing to see the Baskin Robin and Dunkin' Donuts drive through. But at the end of the day, I choose if I am going to go to a place like that. I mean this isn't Soylent Green...it isn't "people" lol.
