Vitamin E deficiency may interrupt a supply line of specific nutrients and rob the brain of the "building blocks" it needs to maintain neuronal health, the findings showed."This research showed that vitamin E is needed to prevent a dramatic loss of a critically important molecule in the brain, and helps explain why vitamin E is needed for brain health," said lead author of the study Maret Traber, professor at Oregon State University in the US.Vitamin E in human diets is most often provided by dietary oils, such as olive oil. But many of the highest levels are in foods not routinely considered dietary staples - almonds, sunflower seeds or avocados.

The year-old zebrafish used in this study, and the deficient levels of vitamin E they were given, are equivalent to humans eating a low vitamin E diet for a lifetime.The findings were published in the Journal of Lipid Research.
