Low dietary intake of fish or n-3 PUFAs is associated with an increased risk of depression and Alzheimer's disease in older populations.
To support brain health and reduce the risk of depression and Alzheimer's, aim for regular consumption of fish or ensure adequate intake of n-3 PUFAs through diet or supplements, especially as you age.
