Memory loss is a natural part of human aging, but there are steps you can take to slow the process down. A recent study suggests that eating more fish may slow cognitive decline in adults over the age of 65.
Participants in the study included 1,566 people over the age of 55 who lived in China. The researchers assessed dietary intake via three day 24 hour recalls at the onset of the study. They then followed all of the participants for approximately five years.
At the conclusion of the study, the researchers found that there was no association between cognitive function and fish consumption for participants between the ages of 55 and 64. However, for those 65 and over, eating at least one serving (approximately 100 grams) of fish per week was associated with a difference in the annual rate of cognitive decline of 1.6 years, compared to those who ate less than one serving per week.
Researchers from the University of North Carolina and Duke University conducted the study. It was published online ahead of print on July 30, 2014, in The Journal of Nutrition.
The results found here were probably due to the high omega-3 levels found in fish. Omega-3s have also been shown to improve inflammation, mood, joint mobility, age related macular degeneration, and the immune system.
Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in DHA and EPA omega-3s.
If you don’t like fish or you’re worried about the high mercury levels found in some fish, consider taking a high quality supplement that has been tested for purity and potency.
