We all know that “20/20″ vision is the ultimate symbol of clear vision. But regardless of one’s vision at the moment, it can diminish over time. Between now and the year 2020, more and more people will experience some extent of vision loss due to age-related macular degeneration and other sight-robbing diseases.

How can we stop the slide? A lot of it has to do with what you decide to put on your plate, and in your glass.

U.S. scientists at the Laboratory for Nutrition and Vision Research are finding that healthy eating could reduce not only healthcare costs, but also the decline of quality of life due to these diseases. The laboratory is part of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Boston.

The “macula” is the 3-millimeter-wide yellow spot near the center of the retina responsible for the central field of vision.

One study showed that people who eat a diet high in vision-protecting nutrients and complex carbohydrates did help shield their eyes from macular degeneration. The complex carb idea runs alongside the low-glycemic-index idea. A food’s glycemic index is an indicator of how fast the carbohydrates it contains will spike blood sugar levels.
