Coffee drinkers, rejoice! Aside from java’s energy jolt, food scientists say you may reap another health benefit from a daily cup of joe: prevention of deteriorating eyesight and possible blindness from retinal degeneration due to glaucoma, aging and diabetes
In the study, mice eyes were treated with nitric oxide, which creates oxidative stress and free radicals, leading to retinal degeneration, but mice pretreated with CLA developed no retinal damage.
The study is “important in understanding functional foods, that is, natural foods that provide beneficial health effects,” said Chang Y. Lee, professor of food science and the study’s senior author. Holim Jang, a graduate student in Lee’s lab, is the paper’s lead author. Lee’s lab has been working with Sang Hoon Jung, a researcher at the Functional Food Center of the Korea Institute of Science and Technology in South Korea. “Coffee is the most popular drink in the world, and we are understanding what benefit we can get from that,” Lee said.
