If you consider taking lutein for macular degeneration, there are some things you should know. Firstly, you may already have enough nutrients in your daily diet.
If you eat kale, spinach, corn, eggs, collards, turnip greens and green beans, you've already found some. The dietary recommendations of the USDA for 2005 are to consume 4-8 mg per day. You can get that in a cup of cooked turnip greens, cabbage, spinach or kale.
If you prefer, you can eat one cup of cooked green peas, a cup of corn and a cup of raw spinach every day. Your total daily would be more than 10 mg.
The eggs are not very good sources, but in one study, researchers found that eating 4 egg yolks per day did not increase the density of pigment in the retina, which is the goal of supplementation. The pigment protects the retina against oxidative damage caused by the sun and other light sources.
The link between lack of lutein and macular degeneration is fairly well established. But as you can see, it is fairly easy to get enough by eating foods rich in nutrients. There are, however, other reasons to consider taking a daily supplement.
Studies indicate that many of the so-called aging diseases are preventable. They may even be reversible.
Low antioxidant status in the body is associated with several of these diseases. A low intake of nutrients, the period is a problem for many people, but it is especially common among the elderly.
Many elderly people suffer from lack of appetite and absorption of nutrient poor. It has been demonstrated that the weight of a person is not indicative of their nutrient intake. There are many rich in calories but poor in nutrients from foods on the market.
But instead of taking lutein for macular degeneration, you might consider taking a multi-nutritional formula. It might improve your overall health and provide additional benefits for your eyes.
In some studies, blueberries have been used, and zeaxanthin. Zeaxanthin is almost identical to the lutein and is always at her side in vegetables. Supplements, however, may not contain. The antioxidants are blueberries called anthocyanins. They seem to be very powerful.
Plain old beta-carotene found in carrots and most multi-nutrient supplements, is known to be important for continued good vision. Studies of lutein and macular degeneration are still in the conceptual stage. Scientists do not "know". They "think".
Although they may be a little harder to find, there are some supplements on the market that contain almost 70 different nutrients, the basic "essential" vitamins micronutrients such as curcumin and zeaxanthin. If the most essential are lacking in the diet, deficiency diseases that are easy to spot will occur.
If there is a lack of micronutrients, it may be that other diseases, less easy to identify, appear. Maybes hand, it is known to increase your nutrient intake without increasing your caloric intake is beneficial for your overall health. So before buying lutein for macular degeneration, you can learn more about what might be what you do for your health.

Taking Lutein For Macular Degeneration - Preliminary Studies Are Promising
Several studies have looked at the value of lutein for macular degeneration. One research group refers to it as "anti-aging ophthalmology". They group it with lifestyle related diseases. It does seem that unhealthy eating habits as well as other lifestyle factors, such as smoking, increase the risk, but here are genetic factors that come into play as well. Researchers first began to look at lutein and macular degeneration, because the antioxidant is one of the components of a healthy retina.
The retina is light sensitive tissue that lines the inner surface of the eye. The macula is a tiny spot inside the retina that is responsible for central vision. Light striking the retina causes a cascade of chemical and electrical events that eventually send signals to the visual centers of the brain. Doctors recommending lutein for macular degeneration do so because some studies have found that taking it and other antioxidants decrease the risk of blindness from the "dry" type of the disease.
While there is no conclusive evidence linking low blood levels of lutein and macular degeneration, it has been noted that there is a lower concentration of both lutein and zeaxanthin in the retinas of people with the disease. Until recently, this could exclusively be measured post-mortem, but one research group has found a way to measure zeaxanthin concentration. So, it may soon be achievable for ophthalmologists to measure the antioxidant concentration in their offices and be able to make certain recommendation.
A six year study conducted at the National Eye Institute in Maryland draws the strongest connection between lutein and macular degeneration prevention. Doctors concluded that it does, in fact, protect against blindness, but they included zeaxanthin in the nutritional formula that was given to patients.
You may be wondering why there is so much excitement about lutein for macular degeneration treatment. But, if you have any familiarity with the disease, you know that there are currently no effective treatments. Loss of central vision is the usual result and it affects 1.2 million Americans.
In addition to lutein and macular degeneration, anti-aging ophthalmology researchers have also looked at the value of fish oil, the antioxidant Astaxanthin and a variety of other "food factors" that they believe should be recommended for early intervention. Basically, it is the fish, fruit and vegetable diet that keeps people healthy.
Taking lutein for macular degeneration prevention may be a good idea. But, if you are over the age of 40 and haven't always followed the fish-fruit-vegetable eating plan, you need more help.
There may not be a strong connection between low levels of lutein and macular degeneration in the elderly. But studies have shown that there is a strong connection between high levels of total antioxidants and "no" macular degeneration. The antioxidants studied were those that are found in the traditional Japanese diet.
The best suggestion for everyone is to find and take a good multi-nutritional supplement that contains a variety of plant extracts, including lutein, zeaxanthin, Astaxanthin, beta-carotene and green tea extract. A good omega 3 supplement (fish oil) is also important. Omega 3 fatty acids are another component of a healthy retina. Increasing total antioxidant intake will do more than taking lutein for macular degeneration, alone.

Macular Degeneration - Are You at Risk?
Macular degeneration is an eye disease that led to the deterioration of the sharp, central vision. The condition is also known as macular degeneration (AMD), which mainly affects adults older than 65 years. Macular degeneration is the leading cause of vision loss in older people.
What are the causes of macular degeneration
Macular degeneration occurs from damage to the macula. The maculauno is sensibile the retina, the light tejidsensibles or on the back of the eye, the light into electrical impulses and sends impulses to the brain via the optic nerve. The macula allows the retina for the treatment of small details. If the macula is damaged, clear central vision and the ability to see detail is lost.
Types of macular degeneration
There are two types of degeneration macularechiamato dry macular degeneration, wet macular degeneration. The dry form of the disease is far Conseitet. Approximately 85-90% of all macular degeneratien circumstances. Dry macular degeneration results from the slow distribution of cells of the macula, leading to progressive loss of central vision. Wet macular degeneration consists of only 10-15% of cases, but is heavier and more rapid progression of the disease. DepressioneWet macular générescence is caused by deterioration of the retina to the flow or dexígekeine zone and results in cracks or columns of the retina. The bodyr respond by creating new blood vessels in the retina bueyygen. These vessels are fragile and the loss of blood and tears in the retina, so that your name. In addition to the loss of fluid into the retina, blood vessels to travel the macula, the pressure on them, just like the roots of trees can be from a sidewalk.
Macular DegenerationStatistiques - United States and Canada
Although wet macular degeneration is a relatively small number of cases,the reason for the vast majority of macular degeneration, with loss of vision. According to a study published in 2004 in the Archives of Ophthalmology, 1.75 million Americans suffer from this condition, and the number should be limited to 3 million by 2020, the U.S. population continues to grow. Overall, about 2% of estadounidense at least 60 years to develop the terms of ions, and the risk increases to 30% in general, the possibility of development of the Krankheit of Americans older than 75 years. In Canada, the prevalence is even greater, with a surprising 23% of Canadians aged 43 or T64 development of the disease. True to its name, the incidence of macular degeneration increases to 56% of Canadians aged 65 to 84 years.
SYMPTOMS

One of the first symptoms of wet macular degeneration is the perception of how crooked the straight lines through the displacement of populations mácula.Las with wet macular degeneration Mai also blind in central vision.
Risk Factors
Although the cause of macular degeneration is not well understood, doctors and researchers have the most important risk factors. Some of these risk factors are inherited and can not be changed. These include a family history of disease, age, race, sex, and eye pigmentation. People with light skin and blue eyes and are more likely to develop the conditions, as well as women, uominiampio. Modifiable risk factors are smoking, poor diet, hypertension, obesity and excessive esPosition the sun.
