Nutrients linked to better brain connectivity, cognition in older adults

  • A study found that higher levels of several key nutrients were associated with more efficient brain connectivity and better cognitive performance in older adults.

A study involving 116 healthy older adults (65-75) has found that higher levels of several key nutrients in the blood were associated with more efficient brain connectivity and better cognitive performance. In fact, the findings suggest that the level of nutrients governs the strength of the association between functional brain network efficiency and cognitive performance.

The study looked at 32 key nutrients in the Mediterranean diet. The effective nutrients, which appeared to work synergistically, included omega-3 and omega-6 fatty acids, carotenoids, lycopene, riboflavin, folate, vitamin B12 and vitamin D.

A pattern of omega-3s, omega-6s and carotene was linked to better functional brain network efficiency.

Omega-3 fatty acids are abundant in fish, walnuts and Brussels sprouts; omega-6 fatty acids are found in flaxseed, pumpkin seeds, pine nuts and pistachios; lycopene is the vivid red pigment in tomatoes, watermelon and a few other fruits and vegetables; alpha- and beta-carotenoids give sweet potatoes and carrots their characteristic orange color.
