Let's Gut Real - Easy to Digest Nutrition Science

Making nutrition science accessible and easy-to-digest. Andrea Hardy, Canada’s Gut Health Dietitian, is on a mission to connect people to credible, up-to-date nutrition information about gut health and digestive disorders. Nutrition misinformation is rampant. If nutrition advice online scares you, it’s probably not true. Let’s Gut Real is all taking the fear out of nutrition messaging, cultivating critical thinking, and helping you understand nutrition science. Andrea talks with guests about digestive health, the gut microbiome, hot nutrition topics, and nutrition misinformation, sharing messages that are easy to consume and that inspire sustainable action. Andrea likes to say her goal is to get people to take nutrition a little less seriously – which may come as a surprise coming from a dietitian. Through humour, she injects fun into her science-based media messages. After all, poop jokes aren’t her favourite kinda jokes, but they are a solid #2.

Nutrition is central to a functioning immune system. It impacts our ability to fight precancerous cells, ward off pathogens, heal injuries, and support our bodies through disease. This week I interview Doug Cook, RD on the role that nutrition plays in our immune function.

Doug Cook is a registered dietitian with over 21 years of experience. With a Master of Health Science in Nutrition, he specializes in functional and integrative nutrition. Doug dives deep into the research on nutrition and science to provide his patients, and the public expert up-to-date information, questioning the way that we’ve ‘always done it’ through his blog and on his podcast Pursuit of Health. I always personally learn so much from him - especially in the way of brain health, and micronutrients. I appreciate that perspective because a lot of times when I’m looking at patients I’m strictly focusing on digestive symptoms. So, it’s nice to kind of take a step back and learn from colleges who actually do their research.

We talk about:

  • How Cook decide to become a dietitian
  • The importance of critically reviewing the up-to-date research instead of trusting the way that things have always been done
  • How nutrition plays a role in immune function
  • What a functioning immune system means in contrast to the idea of people wanting to ‘boost’ their immune system
  • Some of the key nutrients we should be aware of and why
  • Some of the gaps often seen in people’s diets in regards to nutrition & immune function
  • How the gut plays a role in immune function and where nutrition fits in
  • What gut permeability/leaky gut is, why is it so trendy right now, and what the science actually says
  • Some nutrition basics for improving gut permeability and supporting good immune function

Connect with Cook on his website at on his podcast Pursuit of Health on Instagram on Twitter or on his Facebook here as well!
