What does DNA testing tell us about our health?

Updated: Sep 23, 2023

Nutrigenomics is the interaction between genes, nutrients and health. A nutrigenomics test examines DNA to identify variations that can impact our health, which can be supported by nutrition.

Variations in our DNA make each of us unique and can significantly affect our health, and better health outcomes can be achieved by personalising nutrition based on our unique genetic makeup.

Essentially, our DNA affects how we respond to food, how we absorb nutrients, how we exercise, sleep, detox, metabolise and so much more.

Accessing this information through a nutrigenomics test can help with the management of current health issues as well as providing you with the knowledge to take a preventative and proactive approach to your future health.

The test results give us the power to make smart everyday choices about our unique genetic make up so we can optimise our health and embrace our uniqueness.

As a qualified nutrigenomics practitioner, I work with Lifecode GX, the UK’s leading provider of nutrigenomics testing services, to ensure accurate, evidence-based tests and interpretation of results. By analysing your results, I can help you discover the personalised nutrition and lifestyle interventions to best support your unique genetic variants.

A few discoveries I made about my genetics through DNA testing:

LCT: Likely to be lactose intolerant due to low lactase enzyme levels, so eating dairy foods can cause symptoms such as gas and bloating. That explains a lot!

MTRR: Poor converter of homocysteine into methionine, which can negatively affect heart, mental, and nerve health. Thankfully this can be supported with methylated B vitamins. This gene has also given me some insights into my spinal condition.

VDR: Poor transporter of vitamin D and therefore a higher risk of Vitamin D deficiency, which could be a factor in my low bone density. This means I need regular sunlight exposure, test Vitamin D levels, and supplement accordingly.

ACTN3: This gene makes a protein found in fast-twitch muscle fibres, which means my muscle composition is common in elite power athletes! Paralympics here I come.

Accessing this information through a genetic test can give us the power to make smart choices about our diet and lifestyle, which can help with managing current health issues as well as taking a preventative and proactive approach to our future health.


I'm excited to be able to provide personalised nutrition at a deeper level with DNA Nutrition packages. If you’re curious to know how your genes might be impacting your health, book a free mini health review to find out more.
