Aging is a fact of life. Aging with cognitive decline doesn’t have to be. It’s true that genetics can play a role in cognitive decline, memory loss, and conditions such as Alzheimer’s disease,¹ but what’s becoming increasingly clear is the role that nutrition—particularly the balance of omega-3 to omega-6 fatty acids we consume—plays in how well, or unwell, our brains age. By increasing our intake of omega-3s and decreasing dietary omega-6s, which are consumed in excess in our modern diet, we can prioritize brain health now to preserve it well into the future.
