Ditch the White Foods to Keep Your Mind Sharp

White sugar, flour, and other refined carbohydrates are absorbed quickly as sugar into the bloodstream and can cause a spike in insulin levels. This promotes inflammation, which in turn has been linked to an increased risk of Alzheimer's disease. Keep blood sugar stable by choosing slower-burning carbohydrates like whole grains. If whole grains are hard to swallow, then start with good for you energy bars loaded with whole grain goodness.
