I seem to have lost inerest in chips and other snacks that I usedto have a few years or so back. I was only curious if I'm losing interest or whatever xD
Some foods (e.g. chocolate) and flavourings (e.g. chilli powder) are popular because they release enzymes in the brain that create pleasurable sensations (similar to the psychological sensations of copulation). These foods and flavourings "reward you" to a greater extent than other foods that are merely nutritious (e.g. soya protein).
It is not surprising that those foodstuffs that release the pleasurable enzymes in the brain, can be somewhat addictive (and the word "moreish" is often used to describe them when they generate such a craving). Manufacturers deliberately use them in their snack ranges to encourage you to buy and eat more of them.
If you resist the craving for long enough it will disappear, just like the addictions to certain "chemicals" can, if you go "cold-turkey" for long enough.
So yes, you are perfectly correct in observing these effects from your own experiences, and it may or may not be true that you are losing interest in them.
People who are not particularly susceptible to addictions will often choose to ignore their cravings after a brief exposure to these snacks and substances - particularly if they are perceived to be bad for ones social relationships, or physical /mental health.
Maybe your taste buds just changed? Or you just don't care for chips anymore but ya probably lost interest.
I dont think so ... I use to eat french fries a lot & now I still crave them from time to time
