Healthy nutrients

Avocados offer many health benefits due to the nutrients that make up its inner core. They are rich in Lutein, antioxidant vitamins A and E, zeaxanthin, zinc, and monounsaturated fats that help in maintaining the health of the eyes


Avocados consist of two carotenoids that are lutein and zeaxanthin. These act as anti-inflammatory and antioxidant agents and build up pigments in the eyes. Research by Jean Mayer USDA Human Nutrition Research Center indicate that due to consumption of fresh avocados, the amount of lutein gets doubled in the subjects than those who take supplements. This is the same agent that is present in carrots to improve well-being of eye.

Macular degeneration is the deterioration of central portion pf retina though exact cause is not known. According to a study published in the journal Nutrient stated that eating one avocado a day increased lutein levels by 25% that increase macular pigment density and hence slowing down the course of degeneration and improvement of central vision. On the other hand, cataracts cause the cloudiness of eye’s lens which are present behind the iris and pupil. Oxidation and free radical damage is the major cause of this disease. That is why antioxidants present in avocados play a role in reducing the occurrence of cataracts. The famous Nurses’ Health Study further substantiated the fact that people taking high amounts of lutein and zeaxanthin had a reduced need for cataract surgery as well as lower risk of developing new cataracts.

The unique combination of antioxidants and monounsaturated fatty acids in avocado makes it a powerful eye healing agent and keeps eyesight strong along with preventing common eye conditions and complications.
