According to medical research, Beta-carotene has been studied for its potential role in preventing or helping with cataracts. Cataracts are characterized by the clouding of the lens in the eye, leading to blurry or impaired vision. Some studies suggest that antioxidants, including Beta-carotene, may play a preventative role by neutralizing harmful free radicals that can damage the lens.
One study published in the Archives of Ophthalmology found that a higher intake of dietary Beta-carotene was associated with a reduced risk of cataracts in women. The study followed over 30,000 female health professionals for 10 years and found that those with higher intake levels of carotenoids, including Beta-carotene, had a lower risk of developing cataracts.
However, other research studies have yielded conflicting results. For example, a study published in the Journal of the American Medical Association found no significant association between Beta-carotene supplementation and Cataract prevention among participants aged 55 to 80 years. Furthermore, excessive intake of Beta-carotene through supplementation has been associated with an increased risk of lung cancer in certain populations, such as smokers.
