When I was first diagnosed with Parkinson's Disease in the late summer of 2024, I knew that it was coming. Not only had I been experiencing symptoms for about 5 years -- lack of arm swing when walking, slowness, stumbling, lost of strength in my right arm and leg...-- but because it runs in my family: both my mother and father were diagnosed with PD in their later years, and my sister in her late 50's. I haven't tested for the marker gene, because whatever the marker is, it just represents a tendency that can be triggered or subdued by environmental and lifestyle factors. That's epigenetics, and the reason to be proactive: What I do matters.
Epigenetics is the study of how the environment and other factors can change the way that genes are expressed, beyond how the DNA is written. About 15% of Parkinson's patients have a family history of the disease, while only 5-10% are thought to have one of the genetic mutations that can predispose one to the disease (LRRK2, PARK2, PARK7, PINK1 or the SNCA gene).
The Before Times
Professionally, I work in the field of Public Health Communications (aka Behavior Change Communications or Social Marketing), and teach in the Master of Public Health program in the Larner College of Medicine at the University of Vermont. I have a doctorate in Educational Leadership and Policy Studies and a Master's degree in Media Ecology. When I trained to be a Health Coach in 2015, the background in the theories of behavior change and research-based best practices, as well as curriculum development, set me up for taking action on the epiphany I was about to have.
In 2016, I was researching a book that brought together these two interests: media and health. The focus was how the media--and advertising in particular--has created a food culture where convenience is the predominant value. In particular, I was deep into studying the tactics of Big Sugar, and how the repetition of images of kids eating sugary cereals on television has made parents and kids think that cereal is an easy and healthful breakfast -- when nothing could be farther from the truth -- when I had an epiphany in a grocery store.
I was finished with my grocery shopping and looking for a snack to eat in the car on the drive home (that's why they put the candy by the checkout!). As I was reaching for the dark chocolate peanut butter cups, I heard myself say, "You can have that, you worked out today." Now, that's something I've said to myself a hundred or a thousand times before, but since I was studying the sugar industry I was able to identify that it wasn't my rational brain talking. That's when it hit me: That's the Sugar Talking! I stood there in the middle of the market for several minutes, dumbfounded. Have I been addicted to sugar this whole time and not realized it? Are all the rationalizations and justifications for having treats consistent with other forms of addiction? How is it possible that sugar is talking to me? It was right then that I decided to change the focus of my research from advertising and policy to biology. And I was going to unravel my sugar addiction, and teach others how to do it too.
It took me two years to heal my dependency on sugar, and I created my first course Breaking Free from Sugar in 2019. To date, over 4,000 people have taken that course, with over 95% of them reporting they were successful reducing their sugar consumption and planning to continue with a sugar-minimal lifestyle. Then I wrote a book about it called The Sweet Tooth Dilemma, which became a bestseller on Amazon.
Because of that experience of healing took two years until I felt like I was on solid ground -- changing 35 years of habits, beliefs and biology doesn't happen over night -- I figure that might also be the case with PD. if I dedicate myself to learning, and experimenting with changing all the lifestyle and environmental factors within my control, that I can reverse the symptoms of Parkinsonism. And I'm giving myself two years to try (though really I won't stop trying :).
Where I am now
When I was officially diagnosed with PD in the late summer of 2024, I went through an emotionally tumultuous period, alternating self-pity and defiance. I joined the Facebook Group on Alternative Healing for Parkinson's, started following organizations and websites (see Resources tab), and generally started experimenting. I had heard that vigorous exercise was one of the only documented ways to slow the progression of the disease, so I started raising my workout game: got a Peloton bike (to use in addition to the weight training classes) and started Rock Steady, a boxing program for people with PD.
Then, in the late fall, I developed a habit of easily-triggered crying. The smallest mention or thought of having PD would send me into uncontrollable waves of tears. It felt like they were coming from my chest. Just flooded with emotions, a mix of grief, feeling sorry for myself, opportunity lost, feeling like something had been taken away from me, and even a bit of resentment -- why me, I'm so healthy?!
The months of crying came to a peak on New Year's Eve. We went out to a Talking Heads tribute band, with the youthful excitement of dancing in the New Year. Except the minute I stepped on to that dance floor, the sobbing started and barely let up for several hours. You see, I was a dancer -- not a professional dancer but a freestyle dancer, who loved to go out dancing and lose myself in the music. I used to pride myself on being able to dance to any type of music. It was a cherished form of tension release, creative expression, and often a workout too. It was the one place I could get out of my head and into my body. But on New Year's' Eve, my body was having none of it. I could barely sway to the beat let alone dance to those well-loved songs in rhythm..
I suppose that was my emotional rock-bottom, because I woke up the next morning with resolve:
- I'm not going to feel sorry for myself anymore
- I'm going to learn and do everything I can to feel the best I can
- I'm going to figure stuff out and share it with the PD community
I am sharing my journey publicly in case I actually am successful in reversing the disease there will be a record, and also to let others with PD share in my up days and down days. We need to stay resilient.
My approach is systems-based, and starts with the assumption that the rise of PD (and other neurological disorders including Alzheimer's) is not natural to ageing: it is our food, our environment, and our lifestyles are creating disease in the body. It is a functional medicine/nutrition approach that looks to address the root causes rather than merely address symptoms.
I don't have anything against addressing symptoms directly too -- I am currently taking a small dose of carbidopa/levidopa.
It is my current mission: to explore, test, and share what works.
Thanks for reading.

The Hidden Hormone Disruptors in Your Home
Every morning, without realizing it, you may be dousing yourself in invisible chemicals that hijack your body’s hormones. From the soap you lather on your skin to the pan you fry your eggs in, your home may be a major source of hormone-disrupting chemicals.
This isn’t fear-mongering—it’s science. More than 86,000 chemicals are registered for use in the U.S., yet fewer than 1,000 have been tested for their effects on human hormones. Among them is a concerning group known as endocrine-disrupting chemicals (EDCs).
Hormones are your body’s messengers, controlling growth, fertility, mood, metabolism, and sleep. When synthetic chemicals interfere with these signals, the result can be subtle yet powerful disruptions that add up over time.
How Hormone Disruptors Hijack the Body
Researchers have identified several main ways EDCs interfere with hormone systems:
Mimicking natural hormones (agonists).
Some chemicals closely resemble hormones like estrogen or testosterone. They “lock” into receptors and send false signals.
Example: BPA in plastics mimics estrogen.Blocking natural hormones (antagonists).
Others occupy receptors, preventing real hormones from doing their job.
Example: Certain pesticides interfere with male hormone activity.Disrupting hormone production or breakdown.
Some speed up or slow down hormone production or clearance, creating imbalances.
Example: Phthalates (in vinyl, fragrances) can lower testosterone levels.Altering transport and storage.
Hormones travel through the body on carrier proteins. Chemicals can interfere, leaving too much or too little available.Epigenetic changes.
Some EDCs flip genetic switches that regulate hormone activity, with effects that can ripple across a lifetime—and even future generations.
Because hormones work in tiny doses, even very low exposures to these chemicals can matter. There's a myth about exposure that goes "it's the dose that makes the poison." But for many chemicals no dose is acceptable. For example, we now know that any amount of lead exposure to a child's developing brain can cause harm.
Common Household Sources of Hormone Disruptors
Here’s where EDCs are most likely hiding in your home:
Plastics & Food Packaging
BPA, BPS, and phthalates migrate into food and drinks.
Found in: plastic bottles, can linings, takeout containers, cling wrap.
Cleaning Products
Alkylphenols and quaternary ammonium compounds disrupt estrogen and thyroid signaling.
Found in: multipurpose cleaners, disinfectants, degreasers.
Personal Care Products
Parabens mimic estrogen; phthalates affect testosterone.
Found in: shampoos, lotions, cosmetics, scented products.
Furniture, Flooring, and Upholstery
Flame retardants (PBDEs) accumulate in household dust.
Vinyl flooring releases phthalates and other chemicals.
Cookware and Textiles
Nonstick coatings (PFAS) are linked to thyroid disease and fertility issues.
Stain-resistant carpets and water-repellent fabrics also contain PFAS.
Why It Matters
The World Health Organization calls endocrine disruption a “global public health threat.” Research links exposure to:
Early puberty in children
Fertility issues in both men and women
Thyroid disease
Obesity and diabetes
Certain cancers (breast, prostate, thyroid)
This isn’t just a problem for workers in factories. Most exposure happens right at home—through dust, air, food, and daily product use.
What You Can Do Right Now
You don’t need to overhaul your entire life in one day. Instead, start with swaps that have a big impact on daily exposure.
Ditch Plastic Food Storage. Switch to glass, stainless steel, or silicone.
Go Fragrance-Free. “Fragrance” can hide dozens of undisclosed chemicals.
Rethink Cookware. Choose stainless steel, cast iron, or ceramic instead of Teflon or aluminum.
Vacuum with a HEPA filter. Helps reduce hormone-disrupting flame retardants and PFAS in household dust.
Check Labels and Certifications. Look for EWG Verified, MADE SAFE, GreenSeal.
Consider an air filter. A HEPA air filter in the bedroom and/or living area can go a long way towards minimizing airborne chemicals and nano plastics.
A Grounded Take
It’s easy to feel overwhelmed when you hear about “forever chemicals” or tens of thousands of untested compounds. But the point isn’t perfection—it’s progress. Each small swap you make reduces your body’s chemical load. Over time, these changes compound into meaningful protection for your health and your family’s future.
The good news? The market for non-toxic, safer alternatives is growing fast. Every time you choose a safer product, you’re not only protecting yourself—you’re helping shift demand toward a cleaner, healthier future for everyone.
