In our Sunday Connections podcast on May 17, 2015, Aunt Bean and I were discussing Dr. Mischley's research on intranasal glutathione. You can still listen to the podcast at:

In her research, Dr. Mishley points out that people with Parkinson's are typically low in glutathione, a lynchpin chemical orchestrator for healthy cells throughout the body, and especially the brain. Something happens to damage the ability of the body's cells to produce this important chemical.
So Aunt Bean asked, "What foods promote the natural production of glutathione?". I said I'd take that "action item". :-)
So I did.
It turns out that foods that are high in sulfur are the key, including cruciferous vegetables like broccoli, other vegetables like kale and collard greens, eggs, and organ meats. Be careful though, these foods also tend to deplete iodine, so be moderate if you have hypothyroidism.
Also foods high in selenium (as alpha lipoic acid), like brussel sprouts, walnuts, and beef help the body produce an important cofactor for glutathione production
