A recent study has found that a flavorant used in microwave popcorn may elevate risk of Alzheimer's disease.
Diacetyl, the flavourant, can make brain proteins into Alzheimer's-linked form, called beta amyloid.
This flavourant has already been in the news for its alleged connection to lung damage in those who work in microwave popcorn factories.
Diacetyl was found to have an architecture similar to a substance that makes beta-amyloid proteins clump together in the brain -- clumping which is a characteristic of Alzheimer's disease.
Researchers also found that the butter flavorant in popcorn can hinder the brain's natural amyloid-clearing method.
