Portion control and food companies

I am getting so sick and tired of food companies deciding what an acceptable portion size is for so many different foods. A well-known chip maker has decided that 2 ounces of chip dip is a suitable amount for dipping chips (they're going with the portability of it, ya know). And for this supposed on-the-go convenience, you get to pay $3.49 for a package of 6 of these little portions. I'm sorry, if I want portability in my chip dips, I'll buy a large container of the flavor of my choice and divide it up into smaller portions of my choosing (I have all kinds of those 1/4 and 1/2 cup plastic containers floating around). I'll pay a lot less for that larger container, and I get to decide what a suitable portion is.
Why does this piss me off so much? Mainly because these companies are jumping on the obesity epidemic bandwagon with their portion-control/calorie limitations and charging the consumer more for it. Just like all the foods that are reduced fat/reduced sugar/reduced whatever-is-bad-for-you-today foods, they are taking out natural ingredients and substituting others that may or may not be good for you and charging you more for the privilege. The really sad thing about all of this? People are buying into the idea that portion control (90 - 100 calories for a snack) is going to help them lose weight/keep it off. These food companies don't always come right out and say "If you buy our insert whatever portion-controlled item here you'll lose weight and keep it off forever", but they sure as hell imply it. And people who still believe in The Fantasy of Being Thin will buy it, and then wonder why it didn't help them. Will they blame the marketing? Probably not, they'll blame themselves, just like they do when their Weight Watcher's, Jenny Craig, NutraSystem ad nauseum diets fail to make them permanently thin. Cynic that I am, I can see the day coming when you won't be able to buy anything unless it's in those damned portion-controlled packs. Like I don't already have a hard enough time budgeting money for food so DH and I can eat a wide variety of foods while controlling his blood sugar (and make sure he gets a good lunch and snacks for work without sending his blood sugar bouncing all over the place). I finally found a cereal that he can eat (and actually likes) that isn't so high in sugar and carbs/low in fiber, but it costs about 50% more than a similar regular cereal (because it's for diabetics, natch).
I think all the hype about food and health is not about health at all, it's about making us think it's about health so they make more money off our fears. Sorry, I'm not buying it (pun fully intended).
