Green Tea May Help Keep Your Vision Clear
Green tea may help prevent glaucoma and other eye diseases according to a study recently published in the April 2010 issue of the Journal of Agricultural and Food Chemistry.
The study was conducted by researchers at the Chinese University of Hong Kong and the Hong Kong Eye Hospital.
The researchers fed rats a green tea extract and then analyzed their eye tissue. They found that the eye tissue absorbed a significant amount of the extract.
The increase in levels of the extract in the eye reduced oxidative stress that is associated with DNA damage. This oxidative stress can lead to significant tissue damage which can cause glaucoma and other eye diseases.
Glaucoma is a blanket term for a group of eye diseases that gradually lead to blindness. Over 2 million Americans suffer from the disease. There are few early symptoms so many people afflicted with glaucoma don't even realize they have it.
Beyond eye health, green tea may provide many other health benefits including reducing the risk of Alzheimer's, improving cardiovascular health and reducing the risk of certain cancers.
There are a number of other natural ways to boost eye health and lower the risk of vision loss as you age. For example, increasing your intake of protective nutrients like omega-3 fatty acids, bilberries and carotenoids is a great way to keep your eyes sharp. It is also advisable to avoid foods with a high glycemic index.
