What if Parkinson’s disease could be prevented by simply changing your diet? This is what the results of this scientific study suggest. We tell you everything.
A recent study on Parkinson’s disease makes a surprising link between the development of this neurodegenerative disease and intestinal bacteria. Indeed, researchers have suspected for some time that there is a link between the intestine and the brain, particularly in the case of the development of Parkinson’s disease. A disease that affects more than 200,000 people in France with around 25,000 new cases detected each year. In total more than 10 million people worldwide suffer from this disease.
Recently, a new scientific study suggests that Gut bacteria play a role in Parkinson’s disease. More precisely, a deficiency in riboflavin (vitamin B2) and biotin (vitamin B7). Treatment with vitamin B could therefore be sufficient to prevent the disease. “Riboflavin and/or biotin supplementation is likely to be beneficial for a subset of patients with Parkinson’s disease, in which gut dysbiosis plays a critical role,” indicates Hiroshi Nishiwaki, medical researcher at Nagoya University, in an article relayed by Science Alert.

Parkinson’s disease: a promising treatment
This observation could thus limit the symptoms of the disease. As a reminder, these begin with constipation and sleep disorders, before progressing to dementia and loss of muscle control. Previous research has shown that people with Parkinson’s disease also experience changes to their microbiome long before other signs appear. After analyzing fecal samples from 94 Parkinson’s patients and 73 relatively healthy controls in Japan, Hiroshi Nishiwaki and his team compared their results with data from China, Taiwan, Germany and the United States.

Researchers found a decrease in riboflavin and biotin in people with Parkinson’s disease. Hiroshi Nishiwaki and his colleagues therefore demonstrated that the lack of B vitamins was linked to a reduction in molecules that help create a healthy mucus layer in the intestines. The weakening of this protective layer exposes the intestinal nervous system to a greater number of toxins such as cleaning chemicals, pesticides and herbicides.
A simple treatment based on vitamin B?
These toxins lead to increased inflammation of the nervous system and overproduction of α-synuclein fibrils, molecules known to accumulate in dopamine-producing cells in the substantial part of the brain, ultimately causing the motor and dementia symptoms. of Parkinson’s disease.

A 2003 study showed that high doses of riboflavin could help recover certain motor functions in patients. It is therefore possible that high doses of vitamin B can prevent some damage, according to Hiroshi Nishiwaki and his team.
