BETHESDA, Md. (CNN) -- Are you a junk food junkie?  Maybe you can blame your parents.

A new study finds that poor eating habits may be passed on through the generations.

The news comes from a study published in the medical journal Nutrition.  The author, Dr. Ian Myles says his research shows poor dietary habits may be coded into our DNA.

We all have microbes living in our intestines called "gut flora" and it affects the way we process what we eat. That is inherited through the mother and studies have shown that what a pregnant woman eats can affect a child's flavor preferences.

This new study also shows that a father's bad diet may create a "cellular memory" in the DNA passed on to a child.  that means dad's burger and fries habit may be passed on to the child in the same way as hair color.
