Nutrigenomics is the study of the interaction(s) between a person’s nutrition and their unique genes. 


Your body holds trillions of cells, each with the same instructions personalized to you through your unique DNA. The DNA in each cell is arranged into pairs of chromosomes. Your 23 pairs of chromosomes are then arranged into short segments of DNA-- genes. These genes proceed to dictate what processes occur within the cells, eventually building up every part of your body and helping it continue to function properly. 

The Human Genome Project completed in 2003, providing scientists with a blueprint of the approximately 20,500 genes that make up human beings. Think of it as a map of how humans are built. It shows us what's deep in our cells that make us unique: different heights, different eye colors, different risks for diseases, etc.

Genes are important to the framework and function of the human body. They hold a unique recipe for every protein and direct biological pathways in the body. One gene may make one type of protein, another gene will make another type of protein. It is proteins that make us who we are (physically). Proteins are fundamental to life and our health. They lie at the heart of how our bodies function. They direct everything from how we are built and move, to things we don’t think about like breathing and digesting our food. Some proteins become muscle while some become hormones, enzymes, cell receptors, or bone, for example.

Important new information has become available, showing how strong the link is between nutrition and other vital organs, especially the gut-brain connection.  The food we eat is not just calories.  It is information, that triggers other processes.   90% of serotonin comes from our gut!

The food we eat is not just for us- it's for our vibrant microbiome of bacteria living in our intestines in a symbiotic relationship.  We supply the bacteria food and they provide other functions- they they help digest the food we eat, help keep our gut clear of nasty bacteria, and they release hormones.  What else do they do?  We are just learning.  

The sunlight you feel on your skin is not just warm.  It is a trigger for mitochondria. The sunlight is a trigger for melatonin and serotonin release.  

Our environment, emotional stress, and  epigenetics strongly influence our inherent genetic predisposition 

This, combined with our unique DNA, helps fuel vital metabolic processes:

Important topics:

Your DNA and polymorphisms (SNPs)






Free radicals, oxidative stress

Hormone release and balance


Vitamins (like vitamin D)

Essential elements (like magnesium)

Fat metabolism

Omega 3, Omega 6

Apo E (Apolipoprotein E 4)

DNA repair

Fox03 gene (longevity gene)


Epigenetic variation





Coronary Artery Disease


Brain disorders including





Introduction to Nutritional Genomics

Great explanation of DNA, and basis for nutrigenomics.  Essential viewing for anyone thinking of nutritional genetic testing.  It's complicated, but this video helps simplify it

Your vital Microbiome


Your gut as a hormonal organ.  Astonishing.  A must hear

Goal of restoring the relationship between microbe and man

Diet-Gene Interactions, Epigenetics, the Vitamin D-Serotonin

Half of us are not getting enough magnesium.  Explains why eating our greens is so important!

Should you be eating barbecue meats?  Your DNA will tell you

Do you have Vitamin D deficiency?  Everyone should be tested  Adequate levels 30-60 ng/ ml

Do you have a CYP2R1 mutation that could increase your risk for cancer?  

Maternal antibodies against fetal brain cells 4 x more likely with autism.  Would taking vitamin D help reduce autism?

Nutritional status and Hormone Balance


Oxidative stress and impaired methylation are significant pathways that can help regulate hormones. A comprehensive nutrition assessment and targeted therapeutic interventions can help support these and other essential pathways.  Both female and male hormone replacement. Very informative.
