Nutrigenomics is the study of the effects of food and food constituents (supplements) on gene expression (epigenetics.) Though 23andMe is a great way to get the "bulk genetic information," they are not licensed or advertised to advise one on nutrigenomics. There are a variety of websites available to patients to take this bulk data and help you make sense of it. That said, nutrigenomics is a VERY complicated subject, and is evolving as we speak. If you wish to have an individualized interpretation done, it is best to work with a practitioner who is knowledgeable in nutrigenomics and the various physiologic pathways of methylation, energy production, vitamin and enzyme cycling, etc. I work with a research group that can "data crunch" your bulk genetic data into groupings of system related topics. This, coupled with an extensive symptoms survey, helps to validate whether the indicated variations are an issue or not. Often, this data is coupled with Organic Acids Testing or other metabolic testing to further validate the data. I then take all this information, and help you with an interpretation and action plan. Remember, just because you have inherited a variation in a snp does NOT mean it will be expressed!
