Fiber prevents dementia?

A fiber-rich diet is believed to be beneficial for your health. It is mainly because of the fiber's effect on the improved movement of your intestine. Chronic constipation can be a cause of colon cancer. As well, fiber-rich diet makes you satisfied without taking an excessive amount of calory.

Recently, researchers focus on the anti-inflammatory effect of fiber. They hypothesize fiber-rich diet will prevent you from dementia.

Dementia, especially Alzheimer's disease, and some related illnesses are identified as a chronic degenerative disease of the brain. And, they can be connected with inflammation and oxidation. Thus, managing oxidative stress will reduce the risk for dementia.

Researchers found that a high-fiber diet reduced the level of inflammation in immune cells in the brain with experiments using mice. This result is suggestive because there are no reports so far to show the direct effect of fiber on the brain.

There are several differences between mice and humans in diet and metabolism, of course. Humans can eat a large variety of foods unlikely to any other species. Therefore, I am doubtful to adopt this outcome to humans directly. Nonetheless, it is well high-fiber diet can protect not only your body but also the brain.
