9. Sugar
Too much sugar intake is bad for every system in your body, including the central nervous system. Studies have shown links between regular excess sugar ingestion and Alzheimer’s disease.
10. Air pollution
This is a biggie. The only way to avoid air pollution is to continuously wear an oxygen mask. The air we breathe is full of harmful particles that affect all facets of the human condition.
Air pollution has been found to cause brain shrinkage and cognitive impairment, amongst other things. What we breathe and absorb through skin moves through the bloodstream, permeating every organ—including the brain.
Researchers have linked air pollution to the development and exacerbation of neurodegenerative diseases like Parkinson’s and Alzheimer’s.
