Lutein – What is it, How it Acts, What are Its Health Benefits and Effects

Lutein molecule chemical structure

What Are The Effects of Lutein?

– Nourishes and protects the tissues of the eye;
– Protects retinal degeneration (AMD) ;

– Slows the progression of cataract ;
– Reduces the risk of developing certain cancers (breast, colon) ;
– Increases the hydration and elasticity of the skin ;
– Protect eyes and skin from harmful ultraviolet rays;
– Beneficial for cardiovascular health

Cataract, retinal degeneration or glaucoma … most of these eye diseases are irreversible. They evolve progressively with age and cause considerable loss of visual acuity. According to clinical studies, the risk of blindness is 10 times higher after 65 and 20 times higher after 75 years than in younger people!

To fight against all ocular degeneration, presbyopia to slow or increase visual performance , you have to feed and nourish your eyes ! Some bioactive molecules preserve the photoreceptor cells , others stimulate blood microcirculation of the ocular system. Lutein is particularly important to protect the eyes and keep a good view throughout life! This molecule is not only useful for slow or prevent certain diseases of the eye, but could improve the condition of patients already affected by ocular pathology.

What is lutein?

Lutein is a carotenoid (yellow- orange pigment) known for its beneficial effect on eye health. It is found in broccoli , corn , spinach, peppers, peas, oranges, peaches , lettuce , cabbage and in the egg yolk. The body can not synthesize lutein, it must be provided by food . To cover or enhance lutein daily needs some nutritional supplements are effective .

Concentrated in the macula, retina where the maximum dose of the received solar radiation , and absorbs the filter lutein aggressive waves to the photoreceptor cells . Thanks to its antioxidant action, eye pigment helps neutralize free and removal of deleterious effects of intense light radicals. To its credit are : prevention of lens opacification and cataract therefore , improvement in visual acuity ( day and night ) and fight against the related macular degeneration (AMD ) .

Why you should take lutein and what are its health benefits ?

Lutein reduces the risk of developing eye disease .

The concentration of lutein in the eye is 300 to 1000 times higher than in other tissues. This suggests its importance in the prevention of many eye diseases . It has been scientifically demonstrated that people deficient in lutein are more likely to suffer from related macular degeneration (AMD ) or cataracts ( clouding of the lens ) .

In 1999, the results of two clinical studies ( 36,600 men and 77,400 women ) found a 20% reduction in the risk of cataract formation after regular intake of lutein.

The National Eye Institute in the United States, through the AREDS (Age Related Eye Disease Study ) study followed 3640 patients for more than 6 years. It has been established that an adequate intake of lutein had improved recovery from glare, contrast sensitivity and visual acuity.

A clinical study in Boston with 356 people aged 55-80 years with a high intake of lutein was a significant decrease ( 43%) risk of being hit by a degeneration of macula.

People who consumed equivalent to 30 mg of lutein per day for a period of 140 days showed an increase from 21 to 39 % of the density of the retinal pigment.

Hydrate lutein , nourishes and protects the skin .

Lutein increases the amount of lipids (fats ) found on the surface of the skin. Thus it significantly improves skin hydration and elasticity of the skin. On the other hand , lutein protects against harmful UV rays and reduces the sensitivity to sunburn . It was also demonstrated that this pigment alleviates skin inflammation and reduces redness after prolonged exposure.

Lutein reduces the risk of developing certain cancers.

Some scientific research suggests that a diet rich in lutein is associated with a lower risk of lung cancer. Lutein and other carotenoids may also play a positive role in the prevention of breast cancer. Regular consumption of lutein decreases the risk of developing colon cancer .

Lutein is beneficial for cardiovascular health.

Each additional daily serving of vegetables rich in lutein is associated with a 4% lower risk of heart disease. A study of 480 individuals from 40 to 60 years 18 months also showed that men consume more lutein had a lower risk of stroke risk.
