Researchers at the Department of Ophthalmology and Jules Stein Eye Institute, University of California-Los Angeles, recently studied the association between consumption of fruits and vegetables and the presence of glaucoma.

1,155 women located in multiple centers in the United States participated in this cross-sectional cohort study. Glaucoma specialists evaluated the women for glaucoma; consumption of fruits and vegetables was assessed using a food frequency questionnaire.

Among the 1,155 women studied, 95 (8.2%) were diagnosed with glaucoma. Analysis of the relationship between selected fruit and vegetable consumption and glaucoma showed:

• Glaucoma risk was decreased 69 percent in women who consumed at least one serving per month of green collards and kale compared with those who consumed fewer than one serving per month.
•  Glaucoma risk was decreased 64 percent in women who consumed more than two servings per week of carrots compared with those who consumed fewer than one serving per week.
• Glaucoma risk was decreased 47 percent in women who consumed at least one serving per week of canned or dried peaches compared with those who consumed fewer than one serving per month.

Although researchers note that more studies are needed to investigate the relationship between nutrition and glaucoma, research to date does indicate that a higher intake of certain fruits and vegetables may be associated with a decreased risk of glaucoma.
