Blue-green algae can increase Alzheimer's risk
Researchers have found the first major environmental factor that might increase the risk of a variety of brain diseases including Alzheimer’s. The toxin, called BMAA, produced by blue-green algae, has been found in plants and seafood, through which it enters the food chain. The research was tested on monkeys by providing a BMAA-rich diet, which later resulted in Alzheimer’s-like illness.
