I'm the retired dietitian in the article. (My neighbors wanted me to share how my walking, etc, improved so dramatically, thus the published article.) Here's an update. I was doing well until late 2013 when I developed an allergy (characterized by flushing and breathlessness) to strawberries and several other foods. By February 2014 I had to stop consuming strawberries. Many of my symptoms began to worsen. In June 2014 I started taking the Swanson brand of fisetin. To approximate the amount in strawberries I divide the each capsule into six portions, taking one at breakfast and one a dinner. Over several months my symptoms again improved.

In January 2015 I became intolerant of rasagiline and synthroid, stopping both in February 2015. Without the rasagiline, I have more tremor, etc, but am able to function well. I'm currently taking 6 carbidopa/levodopa 25/100, and one 25/100 CR at 10 PM.
