Vitamin D Help Improve Vision

Vitamin D not only good for bone growth, but also potent improve eyesight and heart health.

According to researchers, vitamin D is an important element to keep the intake of blood flow to the retina, thus helping to overcome diseases of the eye due to aging, such as macular degeneration.

The research was carried out using young rats given vitamin D for six weeks. The results showed a decrease in levels of beta amyloid, a protein compound associated with the risk of Alzheimer's, in the eyes and the bloodstream of mice, thus making the mice have increased vision.

Professor Jeffrey Glen of UCL's Institute of Ophthalmology, who led the study, explains the small blood vessels carrying blood to the retina become blocked by small molecules from time to time, this is what made ​​him become irritated.

"In humans, this can lead to decrease in the number of light receiving cells in the eye up to 30 percent when the age of 70 years, resulting in reduced vision," said Professor Jeffrey, as quoted by The Telegraph, Tuesday (17 / 1).

Not only that, the mice were given vitamin D also decreased the amount of amyloid in blood vessels, including vessels of the aorta. This suggests that vitamin D can also be useful in preventing various health problems due to an increasingly older age, reduced function of the eye to heart disease.

Prof. Jeffrey added that although vitamin D contained in many foods such as fish and egg yolks, 90 percent of vitamin D is produced by the skin with the help of sunlight. Many people are not getting enough sunlight to produce vitamin D is adequate.
