The holidays are coming.  For those of us who love to eat, we call them the holidaze, or holiglaze --that time when we turn to Men’s Health or Better Homes & Gardens for tips to keep it together.

But maybe not this year. No, not the one-supersize-fits-all approach this year because a new study suggests the secrets are not in magazines but in our own genes.

Nutrigenomics is a field of research that aims to understand why some people respond differently than others to the same foods.

Personalized nutrition is an application of nutrigenomics that helps tailor dietary recommendations to a person's DNA.

In the study, people who receive DNA-based advice improved their diet to a greater extent than those who receive the standard dietary advice say researchers in Nutritional Sciences at Toronto University.

Data was collected from 138 healthy young adults.   They were then split into two different study groups - one was given DNA-based dietary advice for and the other group was given current standard dietary advice. Changes in their dietary habits were assessed after three and 12 months.

The researchers found that subjects who received DNA-based dietary advice started to show improvements to their diets after three months and the changes became even more apparent after 12 months.

To simplify--the more you know, the less you will grow!
