A very qualitative way to look at it:

1. The Earth, and therefore you are formed of the same material that contributes to the metallicity of our Sun
2. Our Sun is a population I star, which means that it has a relatively high metallicity indicative of having formed after the heavy and short lived star of population II had already had their big blow offs.
3. The population II stars divide into early and late groups, and all post-date the assumed population III stars.

From this I conclude that a non-trivial number of the nucleons in your body have been part of a few stars. Maybe as many as five. As Georg notes there has been time for the most prolific path to include many stars (dozens?).

Certainly all the carbon, nitrogen, oxygen and trace elements that make up your body have been part of at least one star.

None of these facts shed much light on the average star-membership-history of the nucleons that make up your body.
