I think you might get one or two bites on a cheap low nutrition bait, but if you want to regularly catch a decent food source bait would do better and certainly work for a longer period of time, I think a lot of good baits nowadays seem to have decent vitamin content,and also other health benefits, and I think that will keep them all coming back, and if there are additives that will do them some good and make them feel better they will keep eating it,
I went gluten free once and ate really healthily much like Kev, and after a week I felt amazing, healthy, clean more focused, just really good, now I eat all manner of junk again I feel sluggish and slow get depressed more easily and don't feel good, you can tell when you eat well, however you can also get addicted to the wrong things,
My analogy is you might walk past the chip shop everyday but you don't always like the smell, occasionally you quite fancy some but then you don't want them again for a long while, whereas meat and veg type things give you the right fuel and you would want to eat them more as you know they will do you good
Now @Highy and the northerners like the occasional Wigan kebab but they wouldn't eat them daily would they?????????
