Lutein is helpful to your vision

As the age increasing, our sights are inevitably getting worse. Normally, when people are 50 years old, some people may be a little younger, people’s vision begin to deteriorate. But now we find that lutein enriched multi-vitamins are helpful to defer people’s vision deterioration.

The aged-related macular degeneration or AMD for short is the main condition in this piece. AMD make a vision loss in the central retina. The reasons cause AMD are complex, but some reasons can be certain that eyes expose in the UV light for long time can make this problem. And a change in the concentration of the macular pigment that compound lutein and zeaxanthin are also believed to make AMD happen.

We can not stop getting old so that our sights are inevitably getting worse, but we can take some measures to delay or minimize the onset of AMD, some tips are as follows: try to manage your blood and avoid getting hypertension; control the cholesterol in a low level; avoid over weighted; do not have too much fat; and do not smoke. The smokers get the risk of AMD higher by two or three times than the normal people.

What is the most important, the more you intake of lutein, the less risk you take AMD, because its cousin compound zeaxanthin will help mitigate AMD. Enough macular pigment compounds are important in eyes health. People can get lutein from the foods such as Brussels sprouts, swiss chard, garden peas, corn, zucchini, broccoli, romaine lettuce, collard greens, turnip greens and kale.

When people get intake some kind of lutein enriched food that whether they get the proper amount of the nutrients is unknown, because it is a big molecule and it dissolves in organic solvents. So if people want to get recommended amount of lutein, they had better drink some kind of oil to help the lutein to get absorbed.

Another way to get proper lutein is to get lutein enriched multi-vitamins. People can easily get the quantity of the recommended nutrient. What is more, some good ones also comes with zeaxanthin which can make lutein have greater effectiveness. Also, they are more convenient.

Some good multi-vitamins also contain some other ingredients; some kind of ones may have about 100 ingredients. Also, accord to different requirements they can be made in different types. For instance, they can be tailored to respectively suit men and women. And good multi-vitamins also include some other good things.

How to Maintain the Health of Our Eyes?

Our eyes are vulnerable to some diseases as we age. When we are over forty, we may suffer from presbyopia; when we are over fifty, we may suffer from Age-related Macular Degeneration (AMD), which can always lead to irreversible blindness. Here we are going to introduce something about AMD and some methods of prevention. The mechanism of AMD is the blood vessels in our eyes may become very fragile and the blood flow into our eye tissues. The most direct result is blurriness as a result of macular degeneration. However, as the conditions get even worse, our eyes will be in complete blindness.

That’s to say; once the macular is damaged or thinned, our vision will be influenced. The reason is our retinas are protected by the macular pigment from coming light. The thinner our macular pigment is, the worse our eyes are.

In fact, some substances play very important role in the protection of our eyes. For example, Lutein is a very effective antioxidant substance than are very useful in the protection of macula.

The scientists have not found such a method currently that can be employed in the cure of Macula Degeneration. But prevention is much important than treatment. Some very common methods can be used for the prevention of such diseases. Following are they.

We should first know what AMD is and what the cause of it is. Some bad habits can reduce the density of macula pigment. Such as, smoking and drinking alcohol can be very irritating for the macula; working under too bright light, as the sun and computer, can also reduce the density of the pigment. As mentioned above that lutein is very effective antioxidant substance which can help slow the process of macula degeneration. In this sense, it is very essential for us to intake foods that are abundant with lutein.

In fact, other materials can also help to slow the process of AMD. Thus, we should intake more other vitamins and mineral, while ingesting lutein.

Some eye doctors recommend that there are four substances that are vital for the health of our eyes.

The first one is, no doubt, lutein that is a kind of very effective antioxidant substance. It is very nice for us to use some lutein pills that are extracted from marigold plant. It is true that these pills are expensive, but effective.

The matter of fragility in the blood vessels can also be prevented by taking Bilberry in which flavanoids and anthocyanin are contained. Our eye muscles can be benefited a lot from this substance. Taking such pills everyday is essential.

The problem of bad elasticity in the blood vessels can also be avoided by intaking some grape seeds extract. If our blood vessels lose their elasticity, we will suffer a lot. These pills can help prompt the circulation of our blood. Take some everyday.

The commonest Vitamin C is still very important, for it is essential for the synthesis of some tissues. Like lutein, it is also an antioxidant substance. Take some Vitamins C pills everyday.

MP density and AMD

Found in the macula, the macular pigment (MP) consists of two pigments or carotenoids: lutein and zeaxanthin. MP is most dense in the center of the macula named fovea. Moreover, these two pigments have different concentration is different parts of the eye. Lutein makes up 67% or greater of the MP in the peripheral retina. But in the central macula, zeaxanthin is the majority that it accounts for up to 75% of the MP.

MP in the eyes can protect them from harmful effects or free radicals caused by excessive exposure to UV rays and blue light. In detail, the two pigments of MP can help prevent age-related macular degeneration. In general, there are two ways to get enough lutein and zeaxanthin. A balanced diet with plenty of green vegetables and fruits as well as dietary supplements of the two nutrients can both offer enough MP.

As supplements are one of the main sources of MP, there are many studies focusing on these supplements as well as their effects. One study named enhancement of macular pigment density by oral lutein supplement (EMPOLS) conducted by researchers in Berne, Switzerland evaluates the relation between MP density and intake of supplements containing lutein. Participants of this study consume 10mg of lutein supplement product labeled VitaluxPlus on a daily basis.

Another observation study named the role of macular pigment in patients with age-related macular degeneration is also being carried out in Switzerland. Expected to complete in December 2009, this study has several purposes. First one is to assess how MP density and its distribution are associated with age-related macular degeneration. A second aim is to identify patients with low MP density. The study is still supposed to improve the early diagnosis of patients susceptible to AMD. Since low MP values are high risks of AMD, the observation study will develop a basis for dietary supplementation of lutein and zeaxanthin.

A balanced diet beneficial to eye health should contain many foods. Lutein is one of the critical elements. Many sources are rich in lutein, including corn, eggs, spinach, carrots, cantaloupe, oranges, red and orange peppers, kale, and collard greens and so on. In order to facilitate the absorption of lutein through the digestive tract, it is also necessary to eat some healthy fat in combination with those raw vegetables.

Find The Cure With Lutein

Nutritional supplements are plentiful in the local vitamin store and which one is best for you will vary depending on age, medical condition and dietary habits. Lutein is a water soluble carotenoid that possesses anti-oxidant properties. Age related macular degeneration (ARMD) patients are particularly helped by the intake of additional anti-oxidants like Lutein. It is ingested orally and reached the target organs like the retina via the blood stream. The immediate benefit of Lutein is seen in the increase of macular pigment optical density. This improves visual function.

In addition, Lutein aids in the absorption of high energy, short wavelength light that has been shown to act as a catalyst to Macular Degeneration and cataracts. Since both the retina and the crystalline lens are vulnerable to oxidative damage, Lutein an anti-oxidant, is of particular benefit in preserving these structures and thus maintaining better ocular health and vision. The two foods that have the highest quantity of Lutein in them are spinach and kale.

Individuals who have deficiencies in the amount of macular pigment are especially helped by Lutein supplements. Patients with poor dietary habits are likewise encouraged to take Lutein. Visual function is improved rapidly upon consumption depending on the blood level of Lutein. Furthermore, since filtering high energy blue light increases contrast sensitivity, one can also expect an improvement there with additional levels of Lutein.

In short, young healthy individuals who eat well will probably not see many benefits with Lutein supplements. Since it is water soluble excess amounts will be excreted so there is no harm to taking extra amount. In patients who suffer from ARMD, cataracts and other ocular conditions who are older and eat poorly, Lutein supplements are of particular benefit. As always, consult your physician when taking any medications and supplements.
