Other research suggests that quercetin may have a variety of benefits in combination with other nutrients. A Dutch study found that a high intake of black tea, which contains a variety of flavonoids in addition to quercetin, reduces the risk of heart disease, and a Finnish study found that people who ate the most whole apples had a lower risk of stroke than those who ate the least.

Substances that protect the heart and its circulation generally protect the brain as well. The common denominator is the network of blood vessels so crucial to both organs. Damage to blood vessels in the brain may impair the communication lines between nerve cells that underlie all mental activity.

Lee can"t say for sure yet whether quercetin can halt neurodegeneration in people. Clinical trials or studies of large populations are needed to see whether his lab results hold up in the real world.

In the meantime, though, Lee heartily recommends apples for everyone. Given the potential benefits of quercetin, plus the other nutritious qualities of apples, he suggests that people add an apple to the mix of fruits and vegetables that they eat each day.

"One apple a day provides a significant amount of quercetin and flavonoids," he notes. The exact quantity of quercetin in an apple varies depending on the year, season and region the apple was grown in. But all apples—from red delicious to fuji—have a large amount.

Choose a fresh apple over applesauce or apple juice for a snack, Lee suggests, since quercetin resides primarily in the skin of the fruit. "Processed food may always have a chance to lose active compounds," he adds.
