Green leafy vegetables lowers risk of glaucoma

Adding more green leafy vegetables to your diet may not be such a bad idea as recent studies indicate that they can actually lower the risk of developing glaucoma among adults.

The study entitled “Association of Dietary Nitrate Intake With Primary Open-Angle Glaucoma” analyzed a Nurses’ Health Study and a Health Professionals Follow-up Study and was published by the JAMA Ophthalmology Publication last January 14.

Based on the findings of the study, green leafy vegetables have proven to be a good source of nitrate, which improves blood circulation and lowers eye pressure.

“Nitric oxide signaling is important for maintaining optimal blood flow, and some evidence suggests that it may also be important for keeping eye pressure low,” lead researcher Jae H. Kang of Brigham and Women’s Hospital and Harvard Medical School in Boston, explained in an email to Reuters.

“The pro of increasing one’s dietary nitrate intake is that, by far, vegetables are the biggest source of dietary nitrate, and vegetables are part of a healthy diet. Higher dietary nitrate intake has been linked to lower blood pressure, better blood circulation and better athletic performance.”

The long term study collected data from over 100,000 adult participants in the US covering the period of 1984 to 2012 in the first study conducted by the Nurses’ Health Study and 1986 to 2012 for the follow up study conducted by Health Professionals which was used as the basis for the result.

Both results were consistent in showing that participants who ate the most leafy greens were 18 percent less likely than those who consumed the least greens to develop any form of open-angle glaucoma.

They were also 48 percent less likely to develop the disease, which is particularly associated with blood flow.

The research also found risk differences to be consistent with nitrate consumption to that of green leafy vegetable intake. ( By: Angel Ong )
