This entire episode is devoted to a single scientific paper.

A recently published scientific article from a high impact factor journal which I think is so important everyone should at least know about it if they haven’t read it.

It’s entitled “Milk and Health” and was published in the New England Journal of Medicine in the 13th February 2020 edition. The authors are Walter Willett and David Ludwig from Harvard University in Boston.

You can read it yourself if you click here (you’ll need to be or become a subscriber to the Journal) or you can listen to this episode in which I summarise the main points made by the authors.

This narrative review article summarises the science on the following topics related to the consumption of cow’s milk and other dairy products:

  • Introduction (including current recommended intakes)
  • Composition of dairy products
  • Growth and development
  • Bone health and fracture risk
  • Body weight and obesity
  • Blood pressure, lipids, and cardiovascular disease
  • Diabetes
  • Cancer
  • Allergies and intolerance
  • Total mortality
  • Organic and grass-fed production
  • Environmental effects
  • Conclusions (including a summary of current evidence)

If you are confused about all the various things you read and hear about cow’s milk, whether you consume it or not, I hope you will enjoy listening to my summary of this well-written and very important medical paper.


Live well, feel well, do well.
