Why Involving Lutein In Your Diet Is Important
The sense ofsight is very important because it allows us to see things and appreciate its beauty and we have our eyes to thank for that. Our eyes are being used every waking second of our lives so that we can see the world around us and be able to do things that we want to do. But the sad thing is that our eyes just like any other organ in our bodies get damaged if we do not take care of it properly. There are a lot of people who have regret their terrible sense of sight because of not taking care of it properly while others regret totally losing their sight. There are plenty of ways to take care of your eyesight and one of the most important things to do is to eat food that has the nutrient lutein.
Where is lutein found?
Lutein is a carotenoid that is normally found in fruits, vegetables or anything that comes from plants. It is normally seen as a yellow discoloration but there are times when a vegetable has so much lutein that it ends up having the color orange. Xantophyll where lutein is found was first thought to be a side effect of plants not having enough chlorophyll but further studies suggests that xantophyll has its own purpose and it is used to protect plants from the harsh blue light that comes from the sun. The sun releases a spectrum of light and among this entire light spectrum, the blue light has the most energy and it can damage the plants and it is the job of the xantophyll to absorb the blue light to prevent damage.
What Does Lutein Do?
When lutein is taken is ingested by a person, the lutein makes its way to the macula lutea of the eye. This is the main reason why the color of the macula is yellowish. The job of the macula is to absorb the blue and ultraviolet light that comes from the sun to prevent eye damage. When there is a lack of lutein, the macula is not able to absorb as much blue light which allows the blue light to reach the retina. This leads to damage on the retina which can lead to having impaired vision.
