As far as scientific evidence can demonstrate, no.
As far as anecdotal evidence suggests, yes.
The likely explanation? If you're the type of person to eat pineapple / drink pineapple juice regularly for a while, you're also likely to do the other things that make your stuff taste delectable - like exercising, eating healthily and not drinking loads of coffee and smoking. Cause if you don't do those other things, you could have all the pineapple you like and still taste bad (particularly smoking).
