The worst thing is that what we find tasty depends a good deal on the composition of our gut bacteria. That on the other hand depends on what we eat (kinda makes sense - by eating something we are helping certain bacteria to grow and make it harder for other). The effect is actually quite strong, to the point where people that eat mostly junk food retch on the mere smell of a healthy vegetable.
