Scientists have said that cocoa in chocolate has protective effects from neurodegenerative diseases like Alzheimer's and Parkinson's.
The benefits are achieved as antioxidants in cocoa stimulate crucial pathways at the cellular and molecular level. This is because cocoa stops brain cells from dying at both the cellular and molecular level.
The research found that cocoa activates a neuro-protective pathway which has a direct effect in preventing the death of neurons. They stimulate the brain-derived neurotrophic factor (BDNF) pathway that helps keep neurons and brain signaling healthy.
