Lectins are carbohydrate binding proteins found in a variety of foods, plants and animals. They are most present in plant babies, seeds, grains, legumes and nuts.
Note, the model of Parkinsons disease in a sea elegans worm:
The sea elegans worm is very similar to humans in the neurology sense!
They’ve observed transit of dietary lectins in the worm’s diet move from the gut to the brain of the work through the vegus nerve. Lectins can do this in humans as well! They can move to the brain and effect dopamine signaling!
This effects dopaminogic neurons which is what causes Parkinsons disease.
Notice how anxiety gets worse on vegan diets!
Lectins irritate the gut lining causing leaky gut, triggering the immune system, then physically move through the body through the vegas nerve into the brain, causes an immunologic reaction there leading to psychiatric diseases.
