Remember to Eat Apples

A flavonoid in some fruits and vegetables, called quercetin, might help lower the risk for Alzheimer’s disease, according to a study from Gifu University Graduate School of Medicine in Japan. In previous studies, these researchers found that quercetin delayed memory deterioration in mice. In this study, they investigated the long-term effects of quercetin intake on memory recall in mice and found that memory recall was enhanced in aged mice fed a quercetin-rich diet. They then used a dementia scale to determine the effects of quercetin supplementation versus placebos on patients with early-stage Alzheimer’s disease. They found that after four weeks of supplementing with quercetin, memory had improved in the supplemented subjects.
