How DNA test results can be used to create personalised health care plans

Say goodbye to fad diets, “detox” trends and spending hundreds of dollars on random supplements that you’re not sure if you actually need (or even know what they do…).

I am a big fan of nutrigenomic (DNA) tests as they are relatively inexpensive and they provide invaluable information about how a person's genes may be affecting their health.

There are five ways I use a client’s DNA test results to create personalised treatment plans:

• Identifying nutrient deficiencies

• Customising supplement recommendations

• Working out the most appropriate diet or foods for their genotype

• Determining if detoxification pathways are working effectively

• Optimising exercise recommendations

Nutrigenomic testing can reveal whether an individual has genetic variations that affect their ability to absorb or utilise certain nutrients. Common nutrient deficiencies associated with genetic variations include folate, vitamin A, vitamin C, vitamin B6, vitamin B12, vitamin D, choline and omega 3 fatty acids.

Information about a client’s genetic variations can be used to design a personalised nutrition plan that provides clients with supplements they actually need and the best type of supplement for that particular client.

Some of you may have heard of the MTHFR gene. MTHFR variations are relatively common, with an estimated 40-50% of Australians having a variation in either one or both of the MTHFR genes. People with MTHFR gene variations have reduced enzyme activity in the folate pathway, often resulting in folate deficiency. These people are advised to avoid folic acid in supplements (and to take folinic acid or methylfolate instead) as they may have difficulty converting folic acid into the active form of folate that the body can use.

Vitamin D is another example. If a person has genetic variations affecting vitamin D metabolism they may need higher dose supplementation to prevent deficiency. They may also benefit from a liposomal form of vitamin D as liposomal supplements allow nutrients to be transported to the cells without being broken down by stomach acid and other digestive processes, resulting in better absorption.

Nutrigenomic testing can provide valuable information about clients’ genetic predispositions towards certain health conditions, e.g. diabetes or obesity. This information assists practitioners to determine the most appropriate diet for each individual client and the specific foods they should consume or avoid.

DNA testing can also help us answer questions relating to detoxification and chemical sensitivity. There are several gene variants that affect detoxification pathways and antioxidant activity, offering an insight into why people may experience fast or slow metabolism of caffeine, increased oestrogen levels, or slow detoxification of particular chemicals. This information can then be used to create a treatment plan that increases a person’s antioxidant intake and supports detoxification pathways.

Finally, genetic testing can identify predispositions to certain exercise-related traits, e.g. muscle strength, endurance, inflammation and injury risk. Practitioners can then use this information to create personalised exercise recommendations that maximise the benefits of physical activity.
