Juice Might Prevent Alzheimer's Disease, Study Suggests

Drinking fruit or vegetable juice several times a week could help protect against Alzheimer's disease, according to a study.

The nine-year study published in The American Journal of Medicine involving nearly 2,000 people, led by Professor Qi Dai of Tennessee's Vanderbilt University, showed that the risk of developing Alzheimer's -- a degenerative brain disease that affects a person's memory, thinking and mood -- was cut by 76 percent among those who drank fruit or vegetable juice more than three times a week.

Among those who drank juice once a week, the risk was reduced by 16 percent.

The study focused on 1,836 dementia-free people in Seattle, Washington beginning in 1991. They were tracked by questionnaires on their lifestyle and eating habits, as well as by cognitive function tests that were conducted every two years.
