Sophia Ruan Gushee is one of the least toxic people you'll meet. That's probably because she wrote the book on it.

She's the author of "The A to Z of D-Toxing" and the host of the Practical Nontoxic Living podcast.

But Sophia isn't a scientist and didn't study harmful plastics in school.

Becoming a mom for the first time forced her to look at her environment in a whole new way. That led her to question the impact of products she used on her family's health.

The questions turned into answers and, ultimately, major lifestyle changes to reduce exposure to toxic chemicals. Her book reads like an encyclopedia and is like a bible for families trying to reduce toxic exposure.

Along the way, Sophia became the go-to expert in all things toxic. She left her dream job to become a practical, nontoxic lifestyle expert.

In her passion, Sophia found her purpose.

The good news?

Leading a less toxic lifestyle doesn't have to be hard. A few simple swaps can lower your exposure and ultimately let you feel better about harmful toxins that are seemingly everywhere.

Sophia is smart, kind and essentially a non-toxic cheerleader for those of us who would like to do better but really don't need it to feel like a lot of work!
