Eating a healthy diet can help cut the chances of developing cataracts - which in some cases can lead to blindness.
(PRWeb UK) June 29, 2010 -- In some cases cataracts can lead to blindness. A study has now found that a healthy diet can help cut the chances of developing cataracts.
A study has found that reducing the levels of fatty food and salt consumed significantly protected women from the lens-clouding eye disease that is the world's primary cause of eye-sight deterioration.
US researchers handed out a survey to almost 2,000 women aged 50 to 79 and examined their eating habits, giving them a Healthy Eating Index score based on the results.
Participants with higher scores consumed less than the guideline levels for fat, saturated fat, cholesterol and salt-derived sodium.
They also ate vegetables, fruits, grains, milk and protein-rich meat, beans, fish or eggs at recommended or higher levels.
Women with the top 20% of healthy eating scores were found to have a 37% lower risk of developing cataracts than those in the bottom fifth of the table.
Although diet was the biggest risk factor, smoking and obesity were also linked to the disease, as was having brown eyes, being short-sighted, and high blood pressure.
The researchers, led by Dr Julie Mares from the University of Wisconsin, wrote in the journal Archives of Ophthalmology: "Lifestyle improvements that include healthy diets, smoking cessation, and avoiding obesity may substantively lower the need for and economic burden of cataract surgery."
Cataracts are caused when cloudy patches appear in the lens of the eye making vision blurred or misty.
In the UK, more than half of people over the age of 65 are believed to have some cataract development in one or both eyes.
