Ruan Living

Through nearly 20 years of rigorous research and study, Practical Nontoxic Living has emerged as a philosophy and method for translating interdisciplinary science into wiser everyday decisions. Ruan Living is where that philosophy takes shape in a real life—mine: my ongoing practice as a wife, mother of three, social entrepreneur, and Manhattan resident, forever weaving more nature into a life lived in concrete.

More than the decisions themselves, I share how I arrive at them: the questions I ask, the evidence I weigh, the tradeoffs I consider, the mistakes that reshape my thinking, and the discoveries that still surprise me. It’s an evolving record—one that leaves room for uncertainty, joy, convenience, and the realities of everyday living.

When I began in 2007, I was motivated to protect my children’s health and development from the toxic exposures that come from what I buy, own, and do. Today, in 2026, I have far less say over my teenage daughters’ choices—and a new reason to turn that same care toward myself. In May 2026, I was diagnosed with an extremely rare congenital heart condition. It hasn’t changed the science of what I do, but it has deepened why I do it: I’ve become more protective of my own body, and more deliberate about the exposures I can actually control.

For example, for decades, I’ve avoided plastic food and beverage containers and stayed mindful of packaging materials. But lately, I’ve been detoxing my diet further to reduce my exposure to microplastics. I didn’t try to overhaul the whole kitchen at once. I started by asking two questions together: which foods are both meaningful sources for my family and genuinely easy for me to change? That overlap—real impact, low friction—is how I decide what to do first, rather than chasing the scariest headline.

My research usually ends up simplifying my life, not complicating it. In trying to eat seafood with fewer contaminants, I found a source that laboratory-tests for mercury and microplastics, and set up a subscription that keeps the freezer stocked—seafood that comes back low on both, and happens to be delicious. The study of how microplastics affect us has only just begun, but I don’t need the science settled to know I’d rather not keep accumulating plastics in my body. And I’m not upending everything either: I make the change that’s within reach, and let the next one come when it feels natural.

Every home, every family, every budget, every body, every season of life carries different priorities and constraints—so this isn’t meant to become your blueprint. It’s an invitation to create your own.

What I hope is that by seeing how I approach decisions where the evidence is evolving, the tradeoffs are real, and certainty is often out of reach, you’ll feel more confident approaching your own. Not because you’ll reach the same conclusions, but because you’ll ask better questions, interpret the evidence more thoughtfully, and make decisions that align with your own values and circumstances.

If Ruan Living makes your next decision a little easier—and a little wiser—it has done its job.

Because Practical Nontoxic Living is about cultivating the discernment to create a healthier, happier future that is uniquely your own.
