Habitual intake of dietary flavonoids and risk of Parkinson disease.

​Adequate consumption of foods packed with flavonoids, especially anthocyanins from berries, may be important in protecting individuals, particularly men, from Parkinson's disease.

This study evaluated the correlation between dietary intake of flavonoids and the occurrence of Parkinson's disease. Researchers studied the diets of 805 men and women for 20 – 22 years and compared the Parkinson's disease odds ratios of all the subjects.

Researchers observed that a 40% reduction in Parkinson's disease risk was observed in men who were regular consumers of foods high in flavonoids, especially anthocyanins from berries. The protective association between flavonoids and Parkinson's disease was not found in women in this study. Data from this study support the theory that eating foods loaded with flavonoids, especially anthocyanins, may help protect individuals, particularly men, from Parkinson's disease.
