When You Need a Brain Boost...
Antioxidants in blueberries help protect the brain from free-radical damage, which could decrease your risk of Alzheimer's and Parkinson's diseases, and improve cognitive processing. Wild blueberries, if you can find them (or grow them!), have even more brain-boosting antioxidants than the cultivated variety.
Sugary foods incite sudden surges of blood glucose that, in the long term, cause sugar highs and lows, and make you as distractable as a toddler in the Disney store. And foods high in saturated fat can clog blood vessels and slow the flow of nutrients and blood to the brain.
