A diet rich in colorful fruits and vegetables could reduce the risk of age-related cataracts (ARC) dramatically, according to an international study by researchers from the University of South Australia and Xi’an Jiaotong University in China.
The study is the first of its kind to verify the link between antioxidant-rich foods and a lower incidence of ARC. Recommended foods include carrots, tomatoes, citrus fruits, peppers, and dark green vegetables, such as spinach, kale, and broccoli.
Worldwide consumption of foods high in antioxidants is well below levels recommended for prevention of cataracts. As the global population ages, researchers observe, the need to change dietary patterns is urgent.
Dr. Ming Li from X’ian Jiaotong University said: “Age-related cataracts are the leading cause of visual impairment among the elderly throughout the world, with unoperated cataracts contributing to 35 percent of all blindness. Although cataract extraction surgery is an effective method to restore vision, it will have cost society more than $5.7 billion by 2020.”
