Personalised Nutrition Based on Your DNA – Part 2 – Exploring the Evidence

Share With:

Is it possible to create a completely personalised diet based on your genes?

This was the topic discussed in the first article of this series. The overall conclusion was yes, but only to a certain extent.

As technology and research advances, so too will the ability to refine and personalise diets.

But what about right now? This article will go further into the research linking certain gene variations and dietary recommendations.

Why Is Nutrigenomics Important?

Nutrition is a difficult and complex science to study.

Much of this can be attributed to the social and psychological aspects that accompany food choices and food preferences. Other lifestyle factors, such as exercise and alcohol consumption can also add to the confusion.

Nutrition research tries to identify if or how a specific nutrient causes a specific outcome. A cause and effect.

A major hurdle in this is individual genetic variation. Some people have an entirely different response to a nutrient due to their genetic make-up. A great example of this is coffee. Some people have a genetic variation which results in them processing caffeine differently, these people can be hypersensitive to the effects of caffeine. This is one of the reasons you see so much conflicting advice about coffee consumption.

Different individual responses to foods and nutrients, such as the above scenario, come down to genetic variation.
