If you could only eat one dish for the rest of your life, it would be pizza. Every topping is possible.
Used to enjoy pizza immensely. These days it is still great taste when I try it but when it goes down in digestive system, burping and general uneasy feeling start to bother me. I think that's the main difference between good and bad food. Good food you don't even notice while digesting, has no side effects. Just provides you with necessary nutrients. Taste might not seem strong at first bite like of highly addictive food, but after a while you get used to it and learn to appreciate its mild, natural taste.
Now I truly enjoy eating cooked veggies and chicken breasts or some other meat or fish, without ton of spices and flavour intensifiers. It just feels good while eating and especially while digesting it.
Of course, this is individual and not everyone has problem with digestive system like I do and side effects and trash food don't bother them in the slightest. Many probably have different food they react badly to. But think that in general spicy, strong food have similar effects to general population.
Today, I barely ingest anything that is specifically made via industrial means. I do eat meat and veggies that are questionably grown, because that is impossible to avoid unless you have ton of money to spend on food or your own gardens. But sodas, sugary food, biscuits, cakes, chocolate, chips, all kind of food that is preprocessed in some way, I just don't eat any of that anymore. Don't even drink juice they sell in supermarket, only made from fresh fruit when I'm in the mood to squeeze it myself.
They still mainly market salami and that kind of food on TV, it's no wonder people are eating it when is the only thing you can see in commercials.
