Regeneration

I have a friend who is a nurse (probably the wrong title, but something like that) who told me that our body is constantly regenerating itself and every seven or so years we literally have a new body.  This is why some people develop allergies they didn’t have, or get over allergies they did have.  I was thinking in this the other day as I was remembering back to the car accident I was in because after my recovery I had a different favorite food. A different favorite color.  I felt like a completely different person.  I started wondering if these news tastes were due to regeneration that took place, and maybe people who went through something traumatic like I did that required healing, caused an increased regeneration that presented itself with these noticeable differences.  That then led me to think of my last pregnancy.  After I delivered my daughter there were some food that I had always been ok with, but now LOVE.  Wouldn’t this too account for a traumatic experience to our bodies that cause this regeneration?  I know countless women who have admitted liking one thing or another, but how tastes change after delivering their child.   I then starting thing about all the stuff you hear about organ donor recipients.  If our bodies are ever regenerating, and recreating ourselves it makes sense how these likes and dislikes are genetically imprinted within us. I however, think it would be hard to claim what is from the say kidney transplant and what is from the patient’s own recovery as it is once again something traumatic to the body.  Just some thoughts.  I would love to hear anything you have to add to this.
