So, some people came over all "well don't eat this nasty crap then" so some other people came over all "but it's cheap and easy and delicious". Now, I don't dispute "easy"; it certainly is a lot easier to buy a microwave lasagne than to prepare your own. I'm not sure about "cheap"; I've never really thought about it, but certainly compared to other low-effort food options (for instance going out for food). And anyway there whole layers of stuff to do with lack of access to cooking skills, equipment, etc.
But really what's pissing me off is the "delicious" part. It's not that I dispute that some people find this type of food tasty; clearly they do. But I've seen a number of people writing about how these foods are "carefully engineered" to be exactly the sort of thing that most appeals to humans. A view that basically "these foods are super addictive; it is only through sheer willpower that anyone resists them" (and often goes on to insist that people ought to, well, have more willpower - which is a shitty thing to insist; but anyway).
Personally I think this is utter utter bullshit. What these companies have done is not a triumph of food science. It is a triumph of advertising. Of getting into people's heads and saying "this is what food should be"; especially getting to people young.
The thing is that in part because my parents were seriously strict about not having this sort of food; and in part because my current lifestyle is fairly well insulated from a lot of advertising crap; and in HUGE part because I've never lacked money to the point that I've been fretting about the cost of using the oven... well; I've never accustomed myself to eating these types of food, and essentially as a consequence of that I think most of them are simply disgusting. I genuinely would prefer to eat rice and beans. I know most people wouldn't.
I think that the people who write things like "OMG McDonalds makes addictive food we must stop them somehow!" are PART OF THE PROBLEM - they are participating in the advertising campaign that says "this food is addictively delicious".
I think that if "we" want to change the way "people in general" eat the answer has to involve teaching people that the "better" food is delicious, is "normal", etc. etc. And I think we need to get them young. Personally I'm not particularly interested in telling people what they "should" eat; but I would welcome attempts to make healthier food cheaper, and more available so that more people have more actual choice about what they eat, rather than being forced into making the cheapest choice.
