Research from Cornell University indicates that eating apples protects against the tissue-damaging process associated with Alzheimer’s and other neurodegenerative disorders.
The antioxidant quercetin which is found in apples and some other fruits and vegetables appears to protect the brain against oxidative stress.
Fresh apples have the highest levels of quercetin, which is mainly found concentrated in the apple skin, compared to other fruit and vegetables.
Onions have the highest levels of quercetin among vegetables. Berries, particularly blueberries and cranberries, are next in line.
