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.

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.

Natural nutrients sources are better

Lutein is one of the carotenoids that are found in many plants and animals.  Other pigments in the same family include zeaxanthin, astaxanthin, lycopene, beta-carotene and alpha-carotene. Although lutein and zeaxanthin are most commonly thought to benefit the eyes, other pigments also have antioxidant activity in the human body.

During the past several years, most eye doctors or nutritionists recommended a single-ingredient lutein supplement. They think this kind of supplement is beneficial to the eyes, because lutein is most highly concentrated in the retina. And some lutein supplement promoters are airing ads on television. But latest studies have shown other results.

It is true that some earlier studies have proved the effectiveness of lutein supplement or the combination of lutein and zeaxanthin. These nutrients alone can reduce the risk of developing age-related macular degeneration. These studies have considerably promoted the prevalence of lutein supplements.

However, a recent study revealed something different. It compared the blood level of various antioxidants in people with and without macular degeneration. Researchers found that people with high levels did not have macular degeneration. The result is that the total blood levels of carotenoids offer proper protection against the disease.

Supplement products on the market are quire disappointing. A shocking fact is that some lutein supplements as well as vitamins are synthetic. These vitamins can be basically plastic. In particular, most commercial lutein products at low prices are synthetic.

As mentioned before, astaxanthin is another less common antioxidant associated with macular degeneration prevention. A wholesaler of natural astaxanthin named ALGA technologies reveals that nearly all commercial astaxanthin is made of petrochemical sources synthetically.

There is no doubt that these synthetic chemicals have no benefit to human body. But many customers are told to take these supplements on a daily basis. They believe that these lutein supplements as well as multi-vitamins are good for their health. In conclusion, natural sources of these nutrients should be chosen.
