Brain Fuel and Low Glycemic Index

The brain has a very high metabolic rate but no fuel storage. This means that optimal brain function depends on a steady stream of fuel especially glucose in our blood stream. Complex carbohydrates with a low glycemic index provide steady fuel or glucose availability. Glycemic index (GI) is a measure of how rapidly carbohydrates are broken down into glucose. A low-GI food will release glucose more slowly and steadily. A high-GI food causes a more rapid rise in blood glucose. Beans are an excellent low-GI fuel source. Beans are also amazing anti-oxidants with twice the anti-oxidant capacity of blueberries.
Here is a fun, easy to prepare and yummy bean recipe.
