Vitamin D helps protect against macular degeneration in women
According to new study findings from researchers at the University of Buffalo, vitamin D can help protect women under the age of 75 from developing age-related macular degeneration, a leading cause of blindness in older adults.

To investigate, researchers measured the blood levels of vitamin D in over 1,300 women. After adjusting for age and other known risk factors, they found that in women younger than 75, higher blood levels of vitamin D was associated with a significant decreased risk for the condition.

In fact, researchers found that women who consumed the most vitamin D saw their odds of developing early macular degeneration decrease by a staggering 59 per cent, compared with women who consumed the least vitamin D.

Researchers found that risk was lowest when patients consumed 720 international units of Vitamin D per day through foods such as cold water fish, leafy greens, and dairy.

Based on evidence that shows vitamin D can help lower the risk of colorectal, breast and prostate cancers, the Canadian Cancer Society recommends Canadian adults get 1000 international units per day through supplements, sunlight and food sources.

These latest findings were published in the Archives of Ophthalmology. Further studies are needed to determine whether the same protective effect is true for older men.
