What if choosing a diet that's right for you were as easy as a walk to your mailbox? Sound too good to be true? It is (for now), but it's the goal of nutrigenomics. Nutrigenomics, in essence, studies the two-way street connecting genes and nutrition.

Two primary questions drive nutrigenomics: How does nutrition and diet affect our genes, and how do our genes affect the body's response to nutrition and diet?

• Figure Out What Your Body Needs: A customized nutrigenomic diet would reflect your body's specific needs.
• Detox Your Body: Nutrigenomics is a growing (and relatively young) field of study, yet some nutritionists already offer genetic testing of a limited number of genes in hopes of providing you with a way to improve your diet and your health.
• Explain Food Intolerance: As the study and practice of nutrigenomics advances, it will undoubtedly yield surprising dietary insights and personalized benefits to those who pursue its offerings.
