Antioxidants in coffee, tea may not help prevent dementia, stroke

Antioxidants in Coffee and Tea Prevent Dementia and StrokeDrinking coffee and tea rich in antioxidants may not lower your risk of dementia or having a stroke, according to a new study published Wednesday in the online journal Neurology.

The study may call into question other research suggesting a diet high in antioxidants helps reduce the risk of dementia and stroke.

Researchers followed approximately 5,400 people aged 55 years and older for nearly 14 years. The participants had no signs of dementia when they began the study and most had never had a stroke. They were questioned about how often they ate 170 foods over the course of the past year and they were divided into three groups based on the levels of antioxidants in their diet – low, moderate or high.

Antioxidants are vitamins, minerals and other nutrients that help protect your cells and repair cell damage caused by free radicals. Free radicals, molecules responsible for aging and tissue damage, may be a factor in heart disease, cancer and other disease.
