Written by Emily Chow, College of Alberta Scholar within the Vitamin and Meals Science program on the College of Alberta and reviewed by our Well being Stand Vitamin Dietitian Staff  

How properly does your physique soak up vitamin D from the solar? How properly does your physique reply to caffeine? Nutrigenomics could offer you that reply. Nutrigenomics focuses on the connection between vitamin and genomic expressions. It explains the affect of genetic variations on the response to meals and the way it may contribute to illness susceptibility. You may additionally hear the time period “nutrigenetics” used interchangeably. The concept of nutrigenomics has opened up the thought of customized diets primarily based in your genetic make-up. The distinction in genes can predict how your physique will reply to sure vitamins. Even individuals of the identical gender, age and life-style can all metabolize and make the most of vitamins distinctly. For instance, variations within the MTHFR gene have been studied to have an effect on the capability to course of folate. One other instance consists of the inflammatory TNF-alpha gene which has been researched to be inhibited by allium meals i.e. garlic, leeks, and many others. Variations on this gene may alter this interplay and the way chances are you’ll reply to it. 

On this weblog put up, we’ll be discussing how nutrigenomics testing is completed, the potential advantages and drawbacks of nutrigenomics in addition to asses its validity primarily based on analysis research.  

Nutrigenomics Testing 

Nutrigenomic testing kits are extensively out there inside Canada by means of commercialized companies. These genetic assessments analyze the person’s genetic variations and supply data on how the person responds to completely different vitamins. That is typically accomplished by means of a saliva pattern, cheek swab pattern or finger-prick blood pattern. The pattern is then despatched off to a laboratory for evaluation. Outcomes can present data in your chance to crave sweets, your skill to drop some pounds with elevated protein or bodily responses to caffeine. These exams typically embrace a session with a healthcare skilled to information you thru recipes and meals that cater to your DNA. Nutrigenomix is among the few corporations that’s administered by a medical skilled as a result of CEO Ahmed El-Sohemy needed to “restore credibility to the sphere”.  

Potential Advantages of Nutrigenomics  

Now that we’ve regarded into what nutrigenomics is and nutrigenomics testing, we are going to now look into a number of the potential advantages of nutrigenomics:

1. Individualized data 

Nutrigenomic eating regimen solutions can supply a greater understanding of how sure meals and vitamins will have an effect on every particular person. 

2. Food regimen-related ailments 

Nutrigenomic information can present data for the prevention or delay of power diet-related ailments. 

3. Allergic reactions and meals intolerances 

Nutrigenomics information can reveal undiagnosed meals sensitivities and intolerances. 

4. Dietary supplements 

Nutrigenomics information can assist decide which dietary supplements your physique wants for optimum well being. 

Potential Drawbacks of Nutrigenomics 

1. Pricey and well timed 

Testing and reporting is usually a expensive and well timed course of that is probably not worthwhile. 

2. Nutrigenomics received’t resolve each vitamin situation 

Genes are only one issue that influences your well being. Different key elements embrace life-style, well being historical past and private preferences. 

3. Validity 

Genetic testing and studies should be interpreted by a healthcare skilled to make certified selections on the affected person. There additionally could also be an absence of enough analysis for this eating regimen to be thought of legitimate.  

4. Privateness 

These testing corporations have an unlimited assortment of DNA which can turn into a privateness concern. A few of these corporations’ privateness insurance policies point out they might share private information with third events. The Federal Commerce Fee warns that hacking may be very potential.  

5. Disappointing outcomes 

Testing may additionally result in sudden well being outcomes as a result of customers could also be dissatisfied with how unactionable the info is. Genes are accountable for lower than 10% of diet-related problems 

Is Nutrigenomics Legitimate? 

Analysis on nutrigenomics is proscribed, however some research counsel that customized DNA diets will be beneficial to the well being of the inhabitants. Analysis by the British Medical Journal urged people with customized nutrigenomic interventions had been in a position to “inspire long-term enhancements in dietary fats consumption above and past gold customary population-based interventions”. Different research have proven that this idea is probably not as promising as thought. One examine discovered {that a} nutrigenomic eating regimen didn’t have any dietary weight reduction results in a gaggle of obese people.

Whereas the nutrigenomics eating regimen will be promising, there’s a lack of enough proof to be thought of legitimate clinically. Extra analysis can be required to find out how lengthy these dietary adjustments will persist in the long term. Whereas researchers insist there isn’t any inherent hurt to nutrigenomic testing, untimely or unrealistic claims of testing will be aversive to credible analysis. Whereas some research counsel that customized genetic eating regimen interventions could also be more practical than normal eating regimen interventions, the precise impact of nutrigenomic diets is basically unsure. 

The Backside Line about Nutrigenomics

The nutrigenomic eating regimen entails a genetic check to supply customized eating regimen solutions primarily based in your genetic variations. This educates individuals to devour optimum ranges of sure vitamins primarily based on their genetic wants. The nutrigenomics eating regimen is a means for us to personalize vitamin to every particular person and it might substitute the one-size-fits-all eating regimen. Whereas there could also be no hurt in finishing a genetic nutrigenomic check, recall that genetics will not be the only real consider figuring out your well being standing.
