ST. PAUL, Minn. –New research shows men and women who regularly eat berries may have a lower risk of developing Parkinson's disease, 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 American Academy of Neurology's 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's 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.
Rise out of the ranks of the low berry consumers. Get bags of cranberries or frozen blueberries or even fresh berries when they are available.
Note the reference to anthocyanins. Those are the sugar-containing equivalents of anthocyanidins. If you aim for foods high in anthocyanins or anthocyanidins or related compounds you end up eating mostly the same foods. Proanthocyanidins (a.k.a. procyanidins) are polymers of flavonoids. In a previous post I pointed to a proanthocyanidin database (in PDF format). You can browse thru the document to look for food ideas aimed at boosting your flavonoid intake.
That USDA Procyanidin Database makes for interesting reading (at least to me). Raw pinto beans are up there with unsweetened chocolate in terms of procyanidin antioxidants and you can eat a lot more pinto beans than chocolate. But cooked pinto beans have about 2 orders of magnitude less of the good stuff. Is that accurate? Blueberries and cranberries are excellent sources. Ditto hazelnuts, pecans, and pistachios. Sorghum is highly excellent. I had no idea. But that's typically cooked. Whereas you can eat the berries and nuts raw. My advice: eat the berries and nuts.
