Food has been innovated on massively over the last 70 years. From the way it is produced to shipped and stored and finally how it is prepared. The industrialization of food has produced instant meals, TV dinners, fast food and led a mono agriculture policy.
A lot of what is labeled as a particular type of food isn't even what it says it is. Look at a loaf of bread sitting on the shelf. It will have 20+ ingredients! Many of them synthetic or unnatural. And it's not just these things added but the process of how it is made that it makes it "not bread".
And that's just the start. The way animals are raised and pumped full of drugs because of this method of raising them. The packages of pre-made food that is full of a list of who knows what to add color and consistency and preservation.
The food industry has been plenty innovating. Between packaged and ready made food and fast food restaurants selling inexpensive meals the innovation is there and widely accepted. The problem is a lot of this stuff is bad for people and responsible for many health problems today and honestly it mainly tastes awful (that parts an opinion to be sure, but it's no wonder that "American food" has such a low opinion around the world).
The food industry had a revolution and it optimized for low price and convenience as people were sold a message that planning, buying ingredients, cooking and washing dishes is a hassle and not something to be proud of and to enjoy. I live in Manhattan and don't have much space but I can cook without hassle. If I had kids I'd be cooking with them and teaching them the value of it.
