Study: Your craving for junk food could be genetic


(CNN) - Are you a junk food junkie? You might be able to blame your parents. A new study finds that poor eating habits may be passed on through the generations.

We all know that what you eat when you are pregnant can in some ways affect your baby, but apparently dad's eating habits may also impact a child's food cravings.

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. Gut flora 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.

And, as health officials have said for years, poor eating habits can also lead to a host of health problems including obesity, and damage to the heart, liver and kidneys.
