Rich in DHA
Docosahexaenoic acid, or DHA, is an omega-3 fatty acid commonly associated with brain function, although it also supports a healthy nervous system.
Fish is an ideal source of DHA, with most of the top food sources of DHA being fatty fish such as salmon, tuna, and cod. Plant sources of omega-3 fatty acids contain alpha-linolenic acid (ALA), which is converted to DHA in the body.
In older adults, low DHA levels are associated with a higher risk of brain diseases such as Alzheimer's dementia.
Support blood circulation
The body is made up of complex systems that don't work independently of each other. For example, the health of your cardiovascular system can affect your brain health.
Keeping your heart healthy can reduce your risk of brain-related health problems like stroke and dementia. When blood vessels are damaged, your brain can face serious consequences.
Fish is considered a heart-healthy source of protein because it is low in saturated fat.
Lower triglycerides
High triglyceride levels in middle age are associated with a higher risk of Alzheimer's disease later in life.
Triglycerides can block blood vessels in the brain and throughout the body, leading to stroke and heart disease. Eating fatty fish containing omega-3 fatty acids can help lower triglyceride levels.
Reduce the risk of dementia
Higher DHA intake has been linked to lower rates of dementia and Alzheimer's disease diagnoses. Nutrients like omega-3 fatty acids can help protect your brain over time and may slow the progression of brain diseases.
