Our genes influence the way we absorb and metabolize micronutrients. Nutrigenomics looks at the influence genetic variation has over micronutrient absorption/metabolism and the biological consequences of this dynamic relationship. Our diet also influences which of these genes are turned on or off! Emerging evidence in the field of epigenetics has demonstrated that not only can we change the expression of our own genes within our own lifetime; sometimes these changes are heritable and affect our children and grandchildren. In this talk we’ll be exploring the intersection between genetics, nutrition, and environment: how your diet, micronutrients, exercise, heat stress, and sleep can change the expression of your genes and how this has profound effects on the way your body functions and ages.

Rhonda Perciavalle Patrick, Ph.D. is an assistant scientist at Children’s Hospital Oakland Research Institute working with Dr. Bruce Ames. She investigates the effects of micronutrient (vitamins and minerals) deficiencies on metabolism, inflammation, DNA damage, and aging in people. She also researches the role of vitamin D in brain function and dysfunction.

In addition to Rhonda’s active role as a researcher, she also functions as a science communicator for a broad lay audience via her web and video presence found at She is passionate about disseminating health-related information in a way that the general public can easily understand. She is a frequent speaker and writer on topics ranging from general health and wellness, to diet and aging, to vitamins and their effects. It is Rhonda’s goal to challenge the status quo and encourage the wider public to think about health and longevity using a proactive, preventative approach.

Rhonda earned her Ph.D. in biomedical science from the University of Tennessee and performed her graduate research work at St. Jude Children’s Research Hospital. She also has a Bachelor’s of Science degree in biochemistry/chemistry from the University of California, San Diego. She has done extensive research on aging, cancer and nutrition, and metabolism.

  1. Americans aren’t ready to hear that diet is impacting them more than they realize and a plant-based diet can prevent and even reverse major health issues. You just have to give up comfortable convenience. The more you eat plant-based the more you crave leafy greens over chips and fruit over candy

  2. For the veggies and vegans algal oil is a good choice for omegas including Dha. You can bypass the fish and go straight to source.

    Other oils that are good for omegas are hemp seed oil flaxseed oil. Spirulina in dry form is full of good nutrients. We dont have to rely on animals to gain our nutrition.
    Now I will watch the end as this is ultra interesting.

  3. Most physicians are not able to make the time to keep up with these findings, however a paradigm shift is very soon in order, this is HUGE! It's going to lead to a major goldmine in the philosophy of mindsets, nutrition, fitness, drugs, and other environmental variables to enhance the health of our lives, and perhaps even alter the aging process. Now we can better understand why some genes have variance in phenotype rather than simply assuming its the environment (abstract statistical reasoning).
