Is it true that it is climate and health friendly to eat deer? Whilst our excessive love of meat from the usual farmed sources continues to dominate climate and health concerns, we ask whether we are paying enough attention to whether the proposed benefits of eating wild animals -or 'game' -are accurate. So, in this week's nugget episode, Daisy and Clare discuss issues relating to the sustainability claims of the UK's wild meat industry.https://www.scottish-venison.info/wp-content/uploads/2024/03/SVA-Carbon-Report-Final-v2.pdf

This week on the podcast we speak to Dr Matthew Nagra.

Dr Nagra is a Doctor of Naturopathic Medicine having studied at the Boucher Institute in Vancouver Canada, after graduating with a Bachelor’s of Science in Microbiology at the University of Victoria. He has also carried out additional training in nutrition, holding a Plant-Based Nutrition Certification from Cornell University and the T. Colin Campbell Center for Nutrition Studies where he’s authored multiple articles on the subject.

And when he isn't in his clinic helping patients improve their health through nutrition, you’ll find him on social media myth-busting and and countering misinformation.

In this episode we review the science on plant versus animal protein, the considerations for plant based athletes, recommendations for the older person and we finally get to ask Matthew all our creatine questions!
