The problem with 'good fresh food' cooked at home is that it is less nutritious than it was 50 years ago.
Intensive growing has reduced the mineral content of the soil (and so the food), and transport over long distances reduces the vitamins in it.
So whether you eat in a wholesome way or not, you still won't be getting the same standard of food that was available 50 years ago.
