Aloha Zenmormon,
drummerxyz's post is a good place to start.
You generally won't hear Chunyi say to do this diet or that, rather he'll talk about using food as a tool for balancing and healing.
Master Lin has mentioned it in more detail in the October 6-day retreat over the last 6 years, and a section of the
Wisdom & Insights Course which is taken from those events goes over some of this.
Much Love, Shawn
