Beets contain nitric acid, which helps with vasodilatation, the process that expands the blood vessels in the body and improves blood flow.
Since beets are a source of nitrates, they may play a role in brain health. Studies suggest that a diet rich in nitrates may have a beneficial effect when it comes to improving cognitive brain function.
Beets are also a great source of betaine, which helps in digestion. They are high in glycemic index, but are great when eaten as either an appetizer or a small side dish.
