It is often heard that home-grown fruits and veggies are a lot tastier than the produce found in the supermarket. Although this question may contain a skeptics element in it, it is so often heard there must be at least some biological ground behind it.
"Industrial" fruits and vegetables are not grown as much for flavor as for convenience, pest resistance, appearance, resistance to peel problems, resistance to bruising, etc. etc. Profitability is the main consideration.
There are many varieties of apple grown in orchards that taste wonderful (better than my grandmother's gnarly green apples) but don't hold up to shipping and storage well.
Finally, please don't get your information from fantasy tales. There are so many good sites for attaining information.
