A new study concluded that older people who follow diets rich in antioxidants found in vegetables, fruits and tea, may be less likely to develop Alzheimer's disease.
The study tracked the cases of 921 people over a period of six years, starting with an average age of 81, and during the study period, 220 of them were diagnosed with Alzheimer's disease.
The researchers said that people who followed a diet rich in flavonoids, which are antioxidants available in vegetables, fruits and tea, were less likely to develop Alzheimer's disease, compared to others and by half.
"Eat fruits and vegetables, especially leafy vegetables, and drink tea from time to time," said Thomas Holland, chief study researcher, who is from Rush University in the American city of Chicago.
He added: "A diet that contains a variety of fruits and vegetables is important to health, especially brain health."
The study team, published in the journal "Neurology", used information on diets to calculate the average of each person's four types of flavonols, found in cabbage, beans, tea, spinach, broccoli, tomatoes, apples, oranges, pears, and others.
