Have you been feeling a little brain dead lately? It may be because of your diet. According to Shape magazine, a new study published in the journal Brain, Behavior, and Immunity states that eating a high-fat diet can actually cause your brain to eat itself.
Researchers actually looked at two groups of mice. The first group was put on a healthy diet of food containing 10 percent fat while the second group was put on an equally healthy diet, but one with food containing 60 percent fat. At eight weeks, the high-fat group of mice had become obese but both groups were similarly healthy in both brain and body. But by twelve weeks, the scientists began to see cognitive problems in the high-fat group. Even brain scans showed that their microglia-the cells in the brain that is supposed to get rid of garbage-had become lazy.
“Normally in the brain, microglia are constantly moving around. They are always moving around their little fingers and processes. What happens in obesity is they stop moving,” explained Alexis M. Stranahan, Ph.D., a neuroscientist in the Department of Neuroscience and Regenerative Medicine at the Medical College of Georgia and lead author of the study. “Dietary fat dramatically alters their dynamic.”
Even though this study was researched amongst mice, a low-fat diet could still have its benefits even among humans. For more information on this study, visit www.sciencedaily.com or www.shape.com.
