Recently I discovered that for $10 you can plug your genetic data into a very practical website that will help you understand your genetic data as well as give you practical steps you can take to improve it. 

In this talk Rhonda Perciavalle Patrick, Ph.D. hits on vitamin D (an important hormone in brain function and dysfunction) as well as the MTHFR polymorphism (results in high homocysteine requiring supplementation with L methyfolate) which many Lyme patients have.  She also discusses limiting food intake as a method of affecting gene suppression in a positive way (calorie restriction & intermittent fasting).  She also discusses how using a sauna and exercise increases longevity.

Nutrigenomics, Epigenetics, and Stress Tolerance

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. This talk explores 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.

For a brief explanation on Vitamin D by Rhonda:    Approx. 4:30
  • 30-80ng/ml the Sweet spot
  • Fish is a great source of D
  • Get your D levels tested regularly
