A glass of orange juice every day can significantly reduce the risk of dementia, a study found.

The researchers followed nearly 28,000 men for two decades to study how their consumption of fruits and vegetables affected their brain power.

The researchers found that men who drank a small glass of orange juice were 47 percent less likely to take care of difficulty remembering or moving in familiar areas.

Disruptions in memory, understanding and bouts of confusion can be early signs of brain deterioration which can eventually lead to life-threatening dementia.

Fruits and vegetables are a rich source of vitamins, including antioxidants, that can help protect the brain.

These health benefits can protect the brain from the buildup of undesirable molecules and maintain proper blood flow to the brain.

Eating fruits, vegetables and orange juice in the long run helps to maintain cognitive function.
