Judith Finlayson — You Are What Your Grandparents Ate: What You Need to Know About Nutrition, Experience, Epigenetics and the Origins of Chronic Disease

In this wide ranging conversation Judith Finlayson reviews the research she writes about in her new book that takes conventional wisdom about the origins of chronic disease and turns it upside down. Rooted in the work of the late epidemiologist Dr. David Barker, it highlights the research showing that heredity involves much more than the genes your parents passed on to you. Thanks to the relatively new science of epigenetics, we now know that the experiences of previous generations may show up in your health and well-being. Shermer and Finlayson discuss:

  • epigenetics and the link to epidemiology
  • why it is so difficult determining causality in medical sciences
  • why correlation is not necessarily causation, but how it can be used to advise on diet and lifestyle changes
  • How many of the risks for chronic diseases, including obesity, type 2 diabetes, high blood pressure, heart disease and dementia, can be traced back to your first 1,000 days of existence, from the moment you were conceived?
  • the association between these diseases and the experiences parents and even grandparents had
  • fruits and vegetables or meat and fat?
  • how poverty affects epigenetics, and
  • epigenetic exaggerations and incautious extrapolations — no miracles promised!

Judith Finlayson is a bestselling author who has written books on a variety of subjects, from personal well-being and women’s history to food and nutrition. She is a former national newspaper columnist for The Globe and Mail, magazine journalist and board member of various organizations focusing on legal, medical and women’s issues. Judith lives in Toronto, Canada.
