Eating Berries May Lower Risk of Parkinson鈥檚
ST. PAUL, Minn. -
New research shows men and women who regularly eat berries may have a lower risk of developing , while men may also further lower their risk by regularly eating apples, oranges and other sources rich in dietary components called flavonoids. The study was released today and will be presented at the 63rd Annual Meeting in Honolulu April 9 to April 16, 2011. Flavonoids are found in plants and fruits and are also known collectively as vitamin P and citrin. They can also be found in berry fruits, chocolate, and citrus fruits such as grapefruit. The study involved 49,281 men and 80,336 women. Researchers gave participants questionnaires and used a database to calculate intake amount of flavonoids. They then analyzed the association between flavonoid intakes and risk of developing Parkinson鈥檚 disease. They also analyzed consumption of five major sources of foods rich in flavonoids: tea, berries, apples, red wine and oranges or orange juice. The participants were followed for 20 to 22 years. During that time, 805 people developed Parkinson鈥檚 disease. In men, the top 20 percent who consumed the most flavonoids were about 40 percent less likely to develop Parkinson鈥檚 disease than the bottom 20 percent of male participants who consumed the least amount of flavonoids. In women, there was no relationship between overall flavonoid consumption and developing Parkinson鈥檚 disease. However, when sub-classes of flavonoids were examined, regular consumption of anthocyanins, which are mainly obtained from berries, were found to be associated with a lower risk of Parkinson鈥檚 disease in both men and women. 鈥淭his is the first study in humans to examine the association between flavonoids and risk of developing Parkinson鈥檚 disease,鈥 said study author Xiang Gao, MD, PhD, with the Harvard School of Public Health in Boston. 鈥淥ur findings suggest that flavonoids, specifically a group called anthocyanins, may have neuroprotective effects. If confirmed, flavonoids may be a natural and healthy way to reduce your risk of developing Parkinson鈥檚 disease.鈥 The study was supported by the National Institutes of Health.
