Researchers find the amino acid, BMAA, can be inserted into neuroproteins. This causes them to misfold and aggregate. BMAA has been detected in the brains of those with ALS.
Chronic exposure to the environmental toxin BMAA may increase the risk for developing neurodegenerative diseases including Alzheimer's, Parkinson's and ALS.
Researchers have found high concentrations of neurotoxins linked to Alzheimer's disease in the fins and muscles of 10 species of sharks. One of the toxins also has been found in shark fin and shark cartilage supplements.
Exposure to the environmental toxin BMAA may elevate the risk of ALS. BMAA is produced by cyanobacteria, a blue-green alga that commonly occurs in marine ecosystems and accumulates in shellfish, sharks, and other sea-life. Those most reliant on sea-foods for their food source may be most at risk.
