Lutein is a carotenoid that occurs naturally in fruits and vegetables. It is found abundant in dark, green and leafy vegetables. Spinach and kale are rich in lutein. Egg yolk is also a good source of lutein. This carotenoid is concentrated mainly in the macula of the eye. However, it is found in lesser amounts in retina, lens and optic nerves. It is one of the best antioxidants for your eyesight. Lutein benefits the eyesight by blocking the harmful blue light that causes a lot of damage to the eyesight.
How is lutein beneficial?
Lutein benefits are numerous. Not just restricted to eyesight, it is also necessary for the healthy functioning of the body. Some of the benefits of lutein are:
Eye health: this carotenoid helps in preventing vision loss. Most importantly, it helps in preventing macular degeneration by increasing the thickness of the macula. It has been proven through research that lutein reduces the risk of cataracts. There are other benefits that lutein has for the eyesight, like, it reduces eye fatigue and sensitivity to glares, strengthens the tissue of the eyes, supports visual acuity and promotes normal functioning of the eyes by increasing lens density.
Benefits for cardiovascular system: lutein present in blood serum act as antioxidants that promote cardiovascular health. It prevents the peroxidation of fat and cholesterol in the blood. This in turn reduces the risk of plaque formation.
Improves skin health: it has been proven through research that lutein is very good for skin health. It can improve the hydration of skin and increase elasticity of skin. As lutein is an antioxidant, it has the potential to prevent damage caused by oxidation. The lipids, fats and oil in the skin is prevented from peroxidation, thereby enhancing the health of the skin.
These are some of the very essential benefits of lutein. As we age, it is important that we take lutein supplements as our body loses the ability to produce lutein. This adversely affects the vision of an individual. It has been proven through research that an individual would need 15-20gms of lutein each day in order to remain healthy. Regular intake of egg yolk, spinach and other green and leafy vegetables can ensure that we have enough lutein in our body that will help us remain healthy.
