Is your vision blurry? I know mine is after sitting in front of the computer for a while. In that case, you and I need to eat more lutein-rich foods, according to Drs. Michael R. and Marc R. Rose. In their book, Save Your Sight, they write, "A few weeks after consuming more lutein-rich foods or lutein supplements, some normal-sighted people report less glare, improved color vision and sharper vision." Theory suggests that lutein and its companion carotenoid zeaxanthin may save our sight by acting "as a shield or filter that helps to absorb harmful UVB light and dangerous free-radical molecules, both of which threaten the retinal tissue," according to Life Extension Foundation's Disease Prevention and Treatment.
Though everyone's sight could benefit from a diet high in lutein, it can literally save the sight of those who have family histories of macular degeneration and other vision loss problems. If someone in your family has experienced loss of sight in old age, then your high-lutein diet should start long before you reach middle age. In a Harvard University-based study, women with diets high in lutein and zeaxanthin experienced a 22 percent reduced risk of cataracts, while men reduced their risk by 19 percent, according to Reader's Digest's Fight Back with Food.
Based on a study described by Laurie Deutsch Mozian in her book, Foods that Fight Disease, a dietary intake of only six milligrams of lutein per day decreases your chances of developing age-related macular degeneration by 43 percent. For that reason, in Bill Gottlieb's Alternative Cures, Dr. Mark Grossman of the Integral Health Center in Rye and New Paltz, New York, advises, "Everyone over the age of 50 should be taking lutein supplements." However, if you are already experiencing macular degeneration or other vision problems, a high-lutein diet can still help you save your sight by increasing the density of your macular pigment. "Macular degeneration may be stabilized or reversed with nutritional intervention," says Dr. Grossman. He later goes on to say, "By far, it's (lutein) the number one nutritional treatment for the disease."
Not only will lutein save your sight, it may also boost your immune system and, accordingly, prevent cancer. "Healthy people seeking to boost overall immune function should consider consuming 5,000 IU of beta-carotene daily, along with other carotenoids, such as lycopene and lutein," writes the Life Extension Foundation. By boosting your immunity, lutein decreases your chances of getting cancer, since development of cancer as a disease is associated with immune system impairment. I know you've probably heard this a million times, but just in case you haven't, I'll say it again: We all have cancer cells. Cancer cells develop in our bodies all the time, but our immune systems normally remove the malignant cells before they can develop into the symptoms we call cancer. In addition to boosting your immune system, lutein may also fight cancer by both protecting your cells from free radical damage and increasing cell-to-cell communication, thus preventing them from turning malignant.
However lutein prevents cancer, we know it works. According to Professor Ralph Moss' book, Antioxidants against Cancer, more than 250 scientific papers demonstrate lutein's potential as an anti-cancer agent. In a study described in Mark Stengler's Natural Physician's Healing Therapies, people with high-lutein diets at any age decreased their chances of developing colon cancer by 17 percent; furthermore, young people with high-lutein diets decreased their chances by 34 percent. Studies show that a diet high in lutein will also decrease your chances of other cancers, including cancers of the lung and breast. According to a study reported in Disease Prevention and Treatment, women who have low levels of lutein have a 2.08-fold increased risk of breast cancer, so not eating enough lutein-rich foods can actually harm you.
In this age of fast food and junk food, cardiovascular disease is more prevalent than ever. Instead of eating french fries as our vegetables, we should be eating more lutein-rich foods. The Life Extension Foundation reports the results in one study, in which participants with the highest blood levels of lutein showed virtually no arterial wall thickening. "This was a good sign that the bad LDL cholesterol had not oxidized inside them and formed the dangerous plaque that can lead to heart attacks," the editors of FC&A Medical Publishing conclude from the results of the same study. High-lutein diets can even decrease smokers' odds of developing cardiovascular disease, according to a study Selena Yeager describes in her book, New Foods For Healing. In this study of 1,900 men, smokers with high lutein levels in their blood experienced 25 percent fewer heart attacks than those with low lutein levels.
It's easy to add more lutein to your diet because it's found in so many foods. Just refer back to the list you read above. Moreover, "lutein is five times more readily available from vegetables than beta-carotene," writes Professor Moss. Just adding a few more fruits and vegetables to your plate each day may save your sight, boost your immune system, prevent you from developing cancer and reduce your chances of having a heart attack. It's so easy to be so healthy.
� Even though cooking any food reduces the amount of lutein � will absorb more of that protective substance if you add a little bit of fat when cooking. � use olive oil instead of animal fats.

"Everyone over the age of 50 should be taking lutein supplements," Dr. Grossman says. That's because many scientific studies have shown that regular intake of the nutrient, which is a pigment found in leafy green vegetables such as kale, collard greens, and spinach, can prevent macular degeneration, he says.
Alternative Cures by Bill Gottlieb, page 428
� "Macular degeneration may be stabilized or reversed with nutritional intervention," says Marc Grossman, O.D., an optometrist, licensed acupuncturist, and codirector of the Integral Health Center in Rye and New Paltz, New York. And the single most important nutrient to prevent or treat it is lutein.
Alternative Cures by Bill Gottlieb, page 428
Besides preventing the condition, lutein may be able to stop or even reverse existing macular degeneration by increasing the density of the macula pigment. "By far, it's the number one nutritional treatment for the disease," Dr. Grossman says.

"Lutein and lycopene possess exceptionally high antioxidant capacity compared to other carotenoids and may be useful in preventing cancer," said Dr. Fred Khachik, a chemist with the U.S. Department of Agriculture. lutein promotes healthy immunity and decreases the growth of cancer. There are already over 250 scientific papers referring to lutein's potential as an anticancer agent. And lutein is five times more readily available from vegetables than beta-carotene.

Lutein has many beneficial effects in experimental animals. It increases the time until the tumor appears, suppresses the growth of breast tumors, and also enhances the growth of normal white blood cells. (340) What was particularly exciting was that very low amounts of lutein, comprising no more than two-thousands of the overall diet by weight, "can efficiently decrease mammary [breast] tumor development and growth in mice." (341)

Lutein and cardiovascular health
For example, individuals participating in the Toulouse study who had higher blood levels of lutein also had a lower incidence of coronary artery disease � Participants with the highest blood levels of lutein showed virtually no artery wall thickening, while those with the lowest lutein levels showed increased arterial thickness. In addition, lutein reduces the oxidation of LDL cholesterol�

The study followed 480 middle-aged men and women for 18 months. During that time, those who had the most lutein in their bloodstream had almost no increase in the thickness of their carotid (neck) arteries. This was a good sign that the bad LDL cholesterol had not oxidized inside them and formed the dangerous plaque that can lead to heart attacks. Results of two other parts of the study, one done in the lab with human tissue and the other with mice, supported the findings of the first.

In a study of almost 1,900 men, Dr. Morris and his colleagues found that men who had the most carotenoids in their blood�not just beta-carotene but also such things as lutein and zeaxanthin�had 72 percent fewer heart attacks than those with the lowest levels. Even smokers, �who got the most of these protective compounds had 25 percent fewer heart attacks than those who got the least.
New Foods For Healing by Selene Yeager, page 517
Dr. James Dwyer, who led this research, recommends eating plenty of lutein-rich foods to keep your arteries clear. "A diet rich in vegetables, including the dark green leafy variety," he says, "will provide sufficient lutein to achieve the levels of persons in our study."
