In this episode of Functional Medicine Research, I interview Dr. Tommy Wood on the question of whether commercial genetic testing for SNPs is helpful or harmful. This is a topic I have wanted to cover in detail for a long time so when I read Dr. Wood’s paper and listened to him speak, I knew his expertise would be invaluable to this conversation. It is important that practitioners and patients know the truth about the current state of genetic testing and whether or not it is scientifically valid or invalid.
Dr. Wood has done the necessary research to outline all of the reasons why genetic testing is not a valuable tool in practice and he presents compelling data that it can be more harmful than helpful. As stated in the interview, this is an area that I have never bought into because the science simply doesn’t support genetic testing or interventions to address SNPs in clincial practice. I think you’ll find this interiew invaluable to your understanding of genetic testing.
If you have any published papers to refute any of this information, myself and Dr. Wood would love to read these papers.
In this episode of Functional Medicine Research I interview Dr. Kara Fitzgerald about her book, “The Methylation Diet” and a preview of her upcoming study on The Methylation Diet. We had a great discussion about topics like methylation and diet, MTHFR, COMT, SAMe, methylated folate and B12, homocysteine, epigenetics and much more.
The MTHFR test or methylenetetrahydrofolate reductase test has become extremely popular due to a number of alternative medicine practitioners promoting it as the source of many chronic illnesses. But is it something you should worry about?
This test is basically looking for two types of genetic mutations known as C677T and A1298C that affect the MTHFR enzyme involved in folate metabolism in your body.
Proper MTHFR enzyme function ensures that homocysteine is properly metabolized to the amino acid methionine which then makes SAMe. SAMe is known as the “universal methyl donor” which is extremely important for serotonin, melatonin and your DNA.
Folate is a B-vitamin and is important because it is at the heart of metabolism and the production of all your cells. Without it, nothing really works well so our list of symptoms and health problems would be extensive.
