The intake of unsaturated fats such as those found in castor oil has been linked with reduced levels of cortical cataracts, notes WebMD. Other nutrients provide benefits for individuals with nuclear cataracts, but no known nutrient is associated with benefits for posterior subcapsular cataracts.Continue Reading
Cortical and nuclear cataracts are different conditions that respond to treatments in different ways, mentions WebMD. The intake of polyunsaturated fats found in vegetable oils may reduce the severity of cortical cataracts, but it does not have the same effect on nuclear cataracts. Those suffering from nuclear cataracts can reduce the severity of their condition by ingesting greater amounts of protein, vitamin A, thiamin, niacin and riboflavin. Castor oil is not known to help with posterior subcapsular cataracts, as determined by a 1992 study involving 3,000 participants with various forms of eye disease.
Other nutrients that may be effective at treating cataracts include hyaluronic acid, lutein and vitamin A, mentions WebMD. Chymotrypsin is an enzyme that is known to reduce damage to the eye from cataracts, and that surgeons commonly use during cataract surgery for this purpose. Some other nutrients for which there is insufficient evidence to determine whether they are effective for treating cataracts include beta-carotene, vitamin C and vitamin E.Learn more about Vitamins & Supplements
