Lower dietary consumption of eicosapentaenoic acid (EPA) and docosahexanoic acid (DHA) might be risk factors for cognitive decline, researchers say. There is growing evidence that very long chain omega-3 fatty acids are beneficial for maintaining cognitive health. 

"While more research is needed to determine whether intake of fatty fish such as salmon, tuna and trout can help prevent against cognitive decline, our preliminary data support previous research showing that intake of these types of fish have health benefits," one researcher said.

What is the takeaway from this research? There is growing evidence that very long chain omega-3 fatty acids are beneficial for maintaining cognitive health, and many Americans do not have an adequate intake of these nutrients. "While more research is needed to determine whether intake of fatty fish such as salmon, tuna and trout can help prevent against cognitive decline, our preliminary data support previous research showing that intake of these types of fish have health benefits," Scott said.
