I had the opportunity to hear Dr. Jeffrey Bland speak recently. It was inspiring! Dr Bland is the father of Functional Medicine, and the originator of the for 4R protocol for a healthy gut (Remove, Replace, Reinoculate, Repair). At the age of 79 he is sharp, articulate and a walking example of health. This was also inspiring because he was talking about epigenetics, and the ‘science of hope’.
Epigenetics refers to the idea that dietary, lifestyle, and environmental factors influence how our genes are expressed. I often work with clients who are concerned about a family history of disease—such as cardiovascular conditions, dementia, or cancer. While these concerns are valid, having a genetic predisposition simply means there can be an increased likelihood of developing certain health conditions, not a certainty.
The encouraging news is that there are actionable steps we can take to reduce risk. Research suggests that genetics may account for as little as 15% of the overall equation. Epigenetics accounts for the remaining 85%. We now have access to tools that help us identify areas where we can optimize our health and make more informed choices.
There are a variety of genetic tests available, and I’ve explored several over the past few years—some of which I’ve shared before. For example, certain tests focus specifically on cardiovascular genetic markers, while others compare chronological age (the number of years we’ve lived) to biological age (how quickly our bodies are actually aging). Biological age is influenced by both internal and external factors. Including nutrition, exercise, sleep quality, and environmental exposures. These elements not only affect how we age but also turning genes on and off.
Recently, I’ve started using a test that highlights areas of health that may benefit from targeted support based on genetics, rather than identifying risk for specific diseases, Many people pursue genetic testing to look for markers linked to conditions like cancer or Alzheimer’s, but that’s not the purpose of this test. Instead, it provides insight about areas to focus your efforts, and potential genetic nutrient deficiencies.
What can we learn from this test?
- Weight Management – Are you likely to have a higher hunger hormone level? Are you more susceptible to weight gain? How detrimental will late night snacking be? Would fasting be beneficial?
- Recovery & Resilience – Are you more sensitive to stress? How quickly do you recover from exercise? Would ice baths or anti-inflammatories support your recovery?
- Antioxidants and Detoxification – Which antioxidants might offer the most benefit? What types of things are potentially harder for your body to detox?
- Cognitive and Neurotransmitter Function – Which areas could benefit from specific nutrients for better functioning (e.g,. recalling details, executive function, spatial learning, high pressure situations, perceived stress)?
- Immune Function – How effectively does your body defend against viruses, bacteria, parasites, and yeast? Which nutrients can best support your immune system?
- Sleep Support – How sensitive are you to caffeine? Is seven hours of sleep enough for you, or do you need more for optimal function and long-term health?
- Energy & Hormones – Which nutrients may best support your energy levels and hormones?
The results can help guide dietary choices and diet type, as well as identify vitamins and minerals to prioritize. One of the best pieces of information provided from this test – a personalized grocery list based on foods with the highest amount of suggested nutrients.
I know privacy can also be a concern when doing genetic tests. This company does not sell customer genetic data. Samples are tracked using barcodes rather than personal identifiers, and you have the option to delete your data after receiving your report. If you’re interested in testing but still have privacy concerns, I can also share an additional workaround.
I’ve found this test to be helpful for anyone looking to further optimize their health and ensure they’re focusing on the areas that will make the greatest impact. It can serve as a valuable reset—helping cut through the noise and bring clarity to your next steps. Once we have your results, we can prioritize key health areas and build a personalized plan with targeted dietary and lifestyle recommendations designed to best support your unique genetic profile.
