Sarah KernionHOST

What makes this population more likely to respond negatively, whether that's you know, we could talk about gut issues, we could talk about mold, we could talk about heavy metals, environmental toxicities, but what have you seen being some of these underlying mechanisms that often get ignored or overlooked that really make a big difference for these kids?

Greer McGuinnessGUEST
One of the big things that I talk to families about and get a good history of is the child's first two to three years of their life.

Greer McGuinnessGUEST
And the reason why I'm looking for the first two to three years of their life is to see if there was anything that could have altered the immune system development and response during that time.

Greer McGuinnessGUEST
So if you're looking at a child who's growing within the first two to three years, they're developing their immune system.

Greer McGuinnessGUEST
So we actually get inoculated or when a baby gets born, they start really trying to develop an immune system.

Greer McGuinnessGUEST
And what we actually do get is a lot of what we would consider the bad guys early on, your proteobacteria, your fungi and things like that.

Greer McGuinnessGUEST
And that's actually super important because those things actually help train the immune system.

Josh MadsenHOST
But what are what's the big picture here? Like, what are the other things that that we can start looking at and working on to make a much bigger change long term?
