Radishes are rich in naturally occurring nitrates—which, unlike unhealthy artificial nitrates found in processed meat, may be beneficial. In a study published in the January 2011 issue of the journal Nitric Oxide, older adults who ate a nitrate-rich diet got a boost in blood flow to the frontal lobe of their brains—an area commonly associated with dementia. Poor blood flow contributes to age-related cognitive decline. Scientists think that the nitrates’ nitric oxide, a compound that keeps blood vessels supple, helps increase brain blood flow. Another bonus for radishes? One radish has just 1 calorie.
