Epigenetics and The Paleo Diet

Epigenetics | The Paleo Diet
 What do you think about epigenetics? Many scientists (in Germany) believe that the concept of the Paleo Diet is no longer tenable.

Thanks a lot,

The Paleo Diet Team’s Response:

Dear Michael,

Epigenetics is defined as the science studying changes in phenotype or gene expression by mechanisms other than changes in DNA nucleotide sequence.1 The phenotype is someone’s appearance which it’s determined by the genotype (stable and heritable) and the environment (nutrition and other lifestyle factors) which give place to the epigenotype (heritable, labile and rapid).1 Epigenetic changes are controlled, among other mechanisms, by methylation and histone modification. Altered methylation pattern and histone modification may lead to increased susceptibility to disease. E.G. cancer is associated to generalized hypomethylation and localized promoters hypermethylation.1 Histone manipulation may also increase or decrease disease susceptibility.2

Both, methylation and histone manipulation are under the control of dietary substances. For example, methylation depends on SAMe availability, which in turn is influenced by vitamin B6, vitamin B12 and folate intake,3 and long chain polyunsaturated fatty acids such as DHA.4 On the other hand, certain substances such as garlic, horseradish, fiber, blueberries, apple, onion, nuts, berries, red grapes, broccoli, etc. are known nutrients involved in histone modification.2

The Paleo Diet is rich is all of these nutrients,5 hence it may exert positive effects upon epigenetics machinery leading to decreased disease susceptibility. Decreased availability of micronutrients is associated to disease severity, probably, through complex epigenetic mechanisms, and supplementation could improve those symptoms.3 Improved epigenetic is influenced by metabolic programming during foetal and early life. These two periods are crucial for the developing newborn and future adult’s health. Hence, The Paleo Diet may confer protection against several diseases improving the epigenetic programming.

We hope this is helpful.
