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.

It’s not always easy to identify what may be causing infant colic or infant allergy reactions. Infant food sensitivities are common and can result in projectile vomiting, reflux, mucousy/bloody stool, and more - which can be very distressing to parents and lead to unnecessary dietary restrictions.

This week I interview Dr. Trill Paullin on Infant Food Sensitivities, how they arise and what we can do to help manage them

Dr Trill is a Molecular Biologist and mother to two daughters who had severe infant food sensitivities and reactions to proteins transferred from my diet to her breast milk.  After she processed the painful fact that she could hurt my children through breastfeeding, she started researching how to produce breast milk they could properly digest.  She discovered that many parents experience the same troubling situation. Through this experience, she wanted to create a place for parents to find answers to their questions about infant food sensitivities and empower them to continue their breastfeeding journey.  That was how Free to Feed was born.  Free to Feed is starting this mission by first creating an at-home test strip that will allow mothers to analyze their breast milk for allergens.

We talk about:

  • How Trill became interested in the field of infant allergies
  • The origin of Trill’s company Free to Feed
  • What the differences are between non-Ige mediated allergies (FPIAP and FPIES) and IgE mediated allergies
  • How the symptoms between these three diagnoses differ
  • How to identify what may be causing infant allergies
  • What the treatment options are for mothers trying to cope with infant allergies
  • How Trill was able to gather data in this area of research that was largely unrepresented in the literature.
  • The research around transferability and reaction timing
  • The lack of support for families dealing with non-IgE mediated infant allergies and the importance of validating these experiences
  • What Free to Feed offers today to help parents navigate this journey.
  • At-home breastmilk test strips as well as infant allergen friendly multivitamins
