Epigenetic change is now recognized as the cumulative effect of our life experiences in controlling gene expression. What is less well known is that this epigenetic influence on our gene expression can extend back to our parents’ and even our grandparents’ life experiences. Let’s dive into this fascinating topic with todays guest expert.

Judith Finlayson is a best-selling author who has written books on a variety of subjects, from personal well-being and women’s history to food and nutrition. Her most recent book ‘You Are What Your Grandparents Ate’ is a revealing take on transgenerational epigenetics and has been translated into German, French, Spanish, Slovenian and Japanese. 

Key points:

-Current understanding – genomic information is transferred but epigenetic information is wiped clean each generation-but not quite so simple. 

-For example, studies have shown that both the children and grandchildren of women who survived the Dutch famine of 1944-45 were found to have increased glucose intolerance in adulthood.

-Other researchers have found that the descendants of Holocaust survivors have lower levels of the hormone cortisol, which helps your body bounce back after trauma.

-Mechanisms for transgenerational epigenetics

-David Barker- hypothesis

-dietary and lifestyle choices she prioritizes to support optimal genetic expression.
