Happy to. This is very US centric and not applicable to many other countries.
Back in the 70s the big bois of processed foods started advertising processed foods. Their marketing guys realised that convenience, in many cases, wins when it comes to perceptions. This is one reason why cornflakes took off. After they stopped advertising it as an anti masturbation food. They found that especially on sundays wives had to wake up way earlier to make food for their families before they all had to go to church. So they started advertising it towards women. Some adopted it because it just meant that they could now sleep longer or be less stressed on sundays. Eventually there was more stuff that was relatively quick. Cornflakes, canned beans, canned something. Premade things that you just had to warm up. And they all had something in common. They werent really nutritious and a bit expensive. But the convenience of them paid off. And if many people adopt something as the new normal it becomes normal. Now it was a normal thing to eat something quick in the morning, like cornflakes or premade sandwiches. Or the new cool thing that was even more convenient. But the things being advertised and slowly adopted were shit. Nutrition and price eventually succumbed to the promise of time savings.
How much time does it take to eat rice and veggies in the morning? Lets say you made it all the day before. 10 minutes of plate > warm up> sit down > eat > clean up.
But this isnt enough. You are used to 10 minutes already. Your boss now wants you to come in at 8. You wake up at 6 and you will be in traffic for an hour to 1 1/2. You have 30 minutes. Now 10 minutes isnt enough anymore. But now nestle has an idea. Just eat a poptart. Its got real fruit inside, tastes sweet and you just have to pop it in the toaster.
Boom, new normal. Ads are everywhere. And who are you to say no to saved time.
- But not just that. Ads are everywhere. But you are strong, you don't watch tv.
- but the Stores have more aisles filled with poptarts than aisles filled with bread and real food. You have no way ro escape. And your health is not that important when you have work at 8 and if you come in at 810 you can lose your job because of at will employment. Also sugar.
And that's how a whole country grows up on trash processed foods and nobody cooks anymore. Because the media, brands, your supermarkets and society tells you that a good breakfast consists of poptarts and a glass of orange juice. And dont even think of offbrands to save money! Theyre disgusting. Only eat poptarts!
