Taste buds

Is it just me or has food, particularly fruit & veg.,lost it's flavour over the past few years? OH and I were eating dinner a couple of days ago and I remarked that the runner beans and carrots were virtually tasteless and she agreed. I grow my own beans and tomatoes and swear that they have a far better taste than shop bought. Is it down to the mass produced, fertilzer bombarded methods these days? What do you think?
