Common Amino Acid Found in Nuts and Fish May Help Fight Alzheimer's Disease

Scientists discovered that arginine, an inexpensive amino acid found in nuts, fish, and meat, can reduce the buildup of toxic amyloid proteins in the brain. This is significant because amyloid plaques are considered a primary cause of Alzheimer's disease. Arginine is already classified as safe for human consumption. The study suggests this cheap, widely available supplement could become part of Alzheimer's prevention strategies.
