Omega-3 fatty acids are considered essential fatty acids this means they are essential to health but cannot be produced by the body. They are also used in other fields of medicine, because omega-3 fish oils are thought to have anti-inflammatory effects. In Italy, omega-3s are given routinely to heart attack patients. Scientists believe the omega-3 fatty acid DHA may be protective against Alzheimer's disease and dementia. Omega-3 fatty acids are highly concentrated in the brain and may be important for cognitive (brain memory and performance) and behavioral function. Omega-3 fatty acids also may slow the progression of plaque buildup and lower blood pressure.
