Summary

Dr. Matthew Nagra is a Vancouver-based naturopathic doctor and nutrition researcher who tackles misinformation around diet and nutrition on social media. This conversation dismantles nutrition's most malevolent misconceptions—from seed oil hysteria to carnivore evangelism. We explore how tribal allegiances have replaced science, why plant proteins aren't inferior, and the rise of LDL denialism. Matt systematically debunks myths while exposing the cherry-picked studies fueling dietary tribalism. In doing so, he shows us how to distinguish between legitimate research and algorithmic propaganda. Matt is a myth-busting extraordinaire. This exchange cuts straight through the noise. Enjoy!

We are going to talk about gut health for a second. Now, you guys know at this point that I am

0:06.6

passionate about longevity, performance, and taking care of my body from the inside out. But

0:12.5

if we're going to be real about it, none of that really matters if your gut isn't functioning

0:17.4

properly. Because as the emergent science is making abundantly clear,

0:22.2

the quality of your gut health is crucial to almost every single other aspect of health.

0:28.1

So we got to do everything we can to ensure that our microbiome is thriving.

0:32.9

And part of that everything is supplementing it with the best prebiotic and probiotic we can find.

0:38.8

All of which is why I turn to Seed and their DSO-1 daily symbiotic

0:43.4

as an essential aspect of basically every day, my daily routine.

Seed really is different.

Their science team is top-notch.

0:51.3

The testing is rigorous and evidence-based.

0:53.8

And their formula really isn't like

0:55.9

others, which is usually, in most cases, just random bacteria thrown together. The DSO-1, however, is a

thanks to their clever capsule and capsule design. Since starting with seed, I have noticed

1:18.3

some pretty real changes in my digestion, more regularity and a little bit lighter after meals.

1:24.9

So whether you're pushing your body and training or grinding through work

1:27.9

projects or just trying to make it through a challenging day, I would tell you, based on personal

1:32.7

experience, that you really can feel the difference when your foundation is solid. Plus, there's
