I've been trying to switch to cleaner products for my three-year-old, but every natural baby wash i find is so expensive and i can't tell if it's actually any better than what we were using before is there a simple way to know which ingredients really matter and which are just marketing oh that's a great question

Joy McCarthyGUEST
yes totally and i would go back to those like red flags you know um so you know the dermatological dermatologists tested natural clean uh those are not regulated terms So the best thing you can do as a parent is read what are the ingredients in the actual product.

Joy McCarthyGUEST
And avoid the preservatives, the parabens and the formaldehyde-releasing preservatives.

Joy McCarthyGUEST
Because those types of preservatives, they're antimicrobials, right? So you don't want to be— That's a preservative, it's an antimicrobial.

Joy McCarthyGUEST
Yeah, so this is my most recent book and I wrote this book and created these recipes with my recipe testers being kids and also being my husband who can be picky.

Bryce WyldeHOST
So as it relates to eczema, and you formulated a bunch of different products specific to this protocol, right? What can you share with us that way?

Joy McCarthyGUEST
Number one, you have to have the prebiotics, which are really the soil, the environment for the probiotics to live and create the correct probiotics.

Joy McCarthyGUEST
But the two most prevalent probiotics, you know, found in infants and children, Bifidobacterium breve, and then, you know, Bifidobacteria longum, probably the most important for the intestine and the skin.

Joy McCarthyGUEST
So then we've got prebiotic, we've got the probiotic, and then we come into the new territory, postbiotics.

Was it hard? Did you feel like you had super high expectations? Did you impose a lot of that on her?

Joy McCarthyGUEST
I knew that, of course, you know, what I eat and the supplements I take and how I treat my body was so important, but I had been doing this for years anyway.

Joy McCarthyGUEST
So it wasn't like I just got pregnant and I was like, oh my gosh, what am I going to do? And when I had Vienna, I always...

Joy McCarthyGUEST
You know, my husband and I always said, like, we're not going to be super rigid.

Joy McCarthyGUEST
We are going to continue to eat the way we do, which is whole and nourishing and never be like, no, you can't have that.
