Gluten-free is still going strong these days.

According to Google Trends, it’s just about as popular now as it was at its peak six years ago, and gluten-free foods still pack the shelves of grocery stores, coffee shops, bakeries, and the like.

In other words, gluten-free dieting is no longer just a buzzword among bloggers, paleo fanatics, and health gurus.

It’s become a bonafide mainstream diet fad.

Despite this, gluten is still a hotly debated and polarizing little protein. Some claim it’s literally poison and should be avoided at all costs and others say the only people that need to limit their gluten intake are people with celiac disease.

To help clear up this confusion surrounding gluten and present a fair, balanced take on the current weight of the evidence, I invited Danny Lennon to join me on the podcast. 

It’s been a number of years since I last had him on the show, but he’s been a member of the Legion Scientific Advisory Board since its inception and also has a master’s degree in Nutritional Sciences. 

He’s also the host of his own podcast called Sigma Nutrition Radio, where he interviews world-renowned experts from the fields of nutrition, medicine, and sports performance.

In this episode, Danny and I discuss all things gluten, including what gluten is, what happens when we eat it, the difference between celiac disease and gluten sensitivity, whether “leaky gut” is a real thing, and more.
