Drinking fruit juice or vegetable juice at least three times a week can reduce the risk of dementia by 76%. This was discovered by researchers at Vanderbilt University in Nashville, USA, after tracking nearly 2,000 volunteers 10 years. The researchers analyzed the consumption of fruit juice and vegetable juice and the aging rate of the brain. The results show that volunteers who drink juice more than three times a week are 76% less likely to develop dementia than those who may not drink juice once a week.

The research results also prove once again that diet plays an important role in preventing dementia. Previous studies have shown that a diet that includes a lot of fruits, vegetables, whole grains, fish and a little red wine can reduce the risk of dementia by 40%. Other studies have shown that eating curry rice or drinking more than two cups of green tea every day can also reduce the risk of dementia. The researchers who participated in the survey said: "We found that drinking fruit juice and vegetable juice often can effectively prevent dementia, and fruit and vegetable juice may play an important role in delaying the onset of dementia."

However, the study did not clearly list which fruit and vegetable juices can reduce the risk of dementia more effectively, but the researchers said that red and yellow fruit and vegetable juices are particularly rich in antioxidants. Harriet Millward, CEO of the British Alzheimer's Institute, said: "There is a relationship between the release of free radicals in the human body and the premature changes of brain cells that eventually lead to Alzheimer's disease. Antioxidants in some fruit and vegetable juices can' scavenge' these free radicals, which is also proved by this study. Vitamin supplements alone will not have the same effect, so drinking more fruit and vegetable juice is the best way to prevent dementia. This study is very important because it tells everyone to take preventive measures in their diet when they are healthy. "
