There are several reasons why you think the old things are not delicious now: first, your taste has changed, and people's taste will change with age. People's taste buds will shrink with age, and their perception of various tastes will become dull, and they will not taste the taste of food more and more, and the taste will become heavier and heavier.

Second, the taste of some foods has really changed. In the past, materials and processing have been replaced by high-speed industrial technology, pursuing efficiency while ignoring quality.

The third is psychological function, the beauty in memory. When we recall these beautiful things over and over again, it is easy to enlarge them, and so is taste memory.
