What are omega-3 fatty acids?
Omega-3 fatty acids are polyunsaturated fatty acids that occur predominantly in oily, deep-sea saltwater fish – such as tuna. Tuna is loaded with omega-3 fatty acids.
These fatty acids appear to have a positive effect on heart rhythm and may even reduce the incidence of the most common type of stroke. In fact, based on current research, omega-3 may reduce the risk of heart disease. Further research shows it may also have a role in preventing macular degeneration, a common form of blindness, and is important for proper fetal neurodevelopment.
