Omega-3 fatty acids, low glycemic index diet protects against age-related macular degeneration

WASHINGTON - Researchers from Tufts University have found that a diet rich in omega-3 fatty acids and low glycemic index food can significantly reduce the risk of age-related macular degeneration (AMD).

The team led by Dr Chung-Jung Chiu, of the Laboratory for Nutrition and ision Research, and Jean Mayer USDA Human Nutrition Research Centre on Aging at Tufts University showed that nutrients, including vitamins C and E, zinc, lutein, zeaxanthin, omega-3 fatty acids (DHA and EPA), as well as low-GI foods can protect against AMD.

During the study, each dietary factor was assigned a percentile score, and factor scores were added up to find each participant's compound score.

The compound scores were related to participants' AMD risk.

"Although the compound score may be a useful new tool for assessing nutrients in relation to AMD, specific dietary recommendations should be made only after our results are confirmed by clinical trials or prospective studies," said Dr. Chiu.

Preventing AMD and delaying disease progression would best preserve people's quality of life while containing healthcare system cost and care challenges.

Food sources of nutrients that support good general and eye health include: citrus fruits, vegetable oils, nuts, whole grains, dark green leafy vegetables, and cold water fish.
