Fish oil contains two important nutrients for brain health: DHA and EPA. These fatty acids are especially helpful for the brain as they are known to play key roles in cognitive function. DHA is one of the most abundant fatty acids in a person’s brain. If you consume them regularly, you can increase your mental energy and improve your memory. One study concluded that consuming foods or supplements rich in omega-3 fatty acids are less likely to lead to the development of Alzheimer’s disease.
A 2003 study shows that seniors aged 60 to 80 who included fish in their diet were less likely to develop macular degeneration, or retinal deterioration, which can lead to impaired vision.
The body cannot produce omega-3 fatty acids, so they must be obtained through diet or supplements. The American Heart Association recommends eating fish at least twice a week. Tuna, salmon, mackerel, herring and sardines are high in omega-3 fatty acids. Fish oil supplements are also available for those who do not plan to include fish in their diet frequently.
