Nutrigenomics: What you need to know

Science looks at how genes influence your health. By Dr. ann sukany-suls

Have you ever wondered how your genetic makeup might influence your health? It’s long been a question of nature vs. nurture. Now, the science of nutrigenomics takes some of the guess work out of the equation.

What is it?
Nutrigenomics involves DNA analysis that identifies genetic variances that may alter certain health concerns such as cholesterol, blood sugar, inflammation, detoxification and bone health.

How does it work?
It may sound like a detailed procedure, but it is actually quite simple. Just like they do on the television show “CSI,” a DNA sample is collected by swabbing the cheek. This is sent to a lab along with a lifestyle questionnaire. After analysis, a full report is provided with an explanation of results and recommendations.

What can it do for me?
I’m sure you have heard the saying, “You are what you eat.” Well, there is a lot of truth to this statement. Just think, if you knew your genetic variances and health risk factors, you could modify your diet appropriately.

For example, the results could tell you if caffeine might accelerate your bone loss, putting you at increased risk of osteoporosis and fractures. It could tell you if you might need more folic acid to reduce a risk factor for heart disease. Perhaps you would benefit from more cruciferous (cabbage family) vegetables to improve your detoxification or omega-3 fatty acids to reduce inflammation. Believe it or not, people with one cholesterol variation do better with daily alcohol consumption. It can identify if you are salt sensitive and may benefit from a low-sodium diet to reduce your risk for high blood pressure. Having this information allows you to customize your nutrition for optimal health.

The future
As technology improves, DNA analysis will become less expensive and more comprehensive. In our lifetime, medicine may finally become a science of wellness and prevention, rather than sickness and treatment. The future is now.
