Study: Polyphenols and PUFAs Boost Brain Cell Growth

(ScienceDaily Summary)

It's now widely accepted that polyphenols (antioxidants) and Polyunsaturated Fatty Acids (PUFAs or "healthy" fats) help improve heart health, but now there's even more reason to include these nutrients in your diet. A new study out of Barcelona has found that both of these nutrients actually help increase you brain's production of neurons.

According to the study, diets high in polyphenols and PUFAs, known as the LMN diet, boost neural cell proliferation and growth in two main areas of the brain, the olfactory bulb and the hippocampus, both of which are greatly damaged in patients with Alzheimer's disease. Despite the fact that the study was performed in mice, the results give support to the hypothesis that a diet made up of foods rich in these antioxidant substances could delay the onset of Alzheimer's disease or even slow down its evolution.

Polyphenols can be found in tea, beer, grapes, wine, olive oil, cocoa, nuts and other fruits and vegetables. Polyunsaturated fatty acids can be found in fish, olive oil, avocadoes and vegetables such as corn, soy beans, sunflowers and pumpkins.
