We Just Got More New Evidence That Parkinson’s Starts in the Gut — Not the Brain

An operation that separates sections of the vagus nerve in the brain from the digestive tract (for the purpose of addressing severe ulcers in the stomach) has shown strong evidence that the gut is where Parkinson’s disease begins. As reported by Science Alert, it’s long been believed that Parkinson’s starts in the brain, but this new discovery shows promise for further research on Parkinson’s as a gut disease, scientists said.

Compelling evidence of the gut’s link to Parkinson’s has been building for quite some time — as has the truth of the old adage that "you are what you eat." It's been well-established that your gut, home to colonies of microorganisms, including bacteria, viruses and fungi, acts as a second brain, providing all sorts of input to your brain.

Research shows that your gut microbiome plays a role in the development of many diseases and health conditions, including obesity and difficulty maintaining weight loss after dieting, as well as depression, multiple sclerosis and, now, possibly Parkinson’s. In short, specific chemicals produced by certain gut bacteria worsen the accumulation of proteins in the brain associated with the disease.

The link is so intriguing, some researchers suggest the best treatment strategy may be to address the gut rather than the brain, using specific probiotics rather than drugs for various conditions once thought to originate solely in the brain. While probiotic supplements can be beneficial, one of the best and least expensive ways to optimize your gut microbiome is to eat traditionally fermented and fiber-rich foods. Healthy choices include lassi, fermented grass fed organic milk such as kefir, natto (fermented soy) and fermented vegetables.
