If you love apples, love the humble banana as well. Eating a banana daily is likely to boost eye health and prevent vision-related diseases, a study has found. Researchers have found that bananas have carotenoid -a compound that is converted into vitamin A in the liver, which is an important precursor for eye health.
According to previous research, foods containing high levels of carotenoids also protect against chronic disease, including certain cancers, cardiovascular disease and diabetes.
The study showed that banana rich in provitamin A carotenoids may offer a potential food source for alleviating vitamin A deficiency -important for sight. To combat vitamin A deficiency, researchers have been investigating methods to boost carotenoids in bananas.
Cara L Mortimer and other researchers from Queensland University of Technology in Australia studied two varieties of bananas to find out why they make very different amounts of carotenoids. They found that the pale yellow, low-carotenoid cavendish variety produces more of an enzyme that breaks down carotenoids.
