Subject: Study shows lutein can boost heart health





Many people consume lutein, either as a supplement in in vegetables containing lutein, because it can provide protection from diseases of the eye. A recent study has shown that lutein can protect the heart as well. Researchers found some correlation between higher levels of lutein in the bloodstream and a lower risk of heart disease, stroke, and metabolic syndrome. Metabolic syndrome is a medical term for a group of conditions including abdominal obesity, high blood pressure, and high triglycerides. Lutein, a carotenoid, is found in dark, leafy green vegetables.

Key Takeaways:

  • Carrot and kale contain the carotenoid lutein that is useful for good eye health. But it has been shown that this compound is also good for the heart.
  • Lutein, a carotenoid, can both help protect the eyes and improve eye health, while reducing the risk of developing both cataracts and age-related macular degeneration.
  • To carry out their study, the scientists first concentrated on current research on lutein. They gathered 4,377 studies that were narrowed down to 71 most relevant studies.

"Dr. Elizabeth Leermakers decided to look into “lutein’s positive effects against inflammation and oxidative stresses in the eyes,” and together with a team of researchers, she searched for links between the presence of lutein (or a lack of the carotenoid) and diseases caused by stressors like heart attack, metabolic syndrome, and stroke."

Maintains Healthy Visual Function*

It has been well established that lutein is present in high concentrations in the retinal tissue of the human eye. However, a study was conducted in human volunteers to determine whether taking lutein in supplement form actually increased the density of the carotenoid pigments present in the macula. In this study of eight individuals, researchers estimated the density of the macular pigments prior to having each individual take 10 mg of lutein daily in supplement form for 12 weeks. Plasma lutein concentrations were measured at 4-week intervals. During the first four weeks of the study, plasma levels increased five-fold from pre-supplement measures, and then remained at this level for the duration of the study. It was also shown that, due to increased deposition of lutein in optical tissues, macular pigment density increased by an average of 5.3% at the 4-week mark, and continued to increase until the duration of the study.1

A study was also conducted to investigate the possible role of specific nutrients in protecting the lens of the eye against aging, a risk factor for compromised visual function. The study was comprised of 376 individuals aged from 18 to 75. Of the nutrients measured, it was found that the lenses of individuals with higher concentrations of lutein and zeaxanthin showed less of an effect from the aging process. The investigators concluded that these carotenoids might play a protective role in supporting the maintenance of healthy vision.2

The Age-Related Eye Disease Study (AREDS) was a landmark study of the effects of diet and antioxidant supplementation on eye health. The study enrolled over 3500 subjects aged 55 to 80 years who were followed for approximately 6 years. Among the data collected in this multi-faceted study was a self-administered Food Frequency Questionnaire (FFQ). The AREDS Report No. 22 examined the data from the FFQs and determined that, of the nutrients evaluated, only lutein and zeaxanthin were directly related to maintaining eye health with statistical significance3. These findings corroborated similar results of an earlier multi-center study published in the Journal of the American Medical Association that also found that those with a higher intake of lutein and zeaxanthin maintained healthier eye function.4 These promising results have spurred the design of a second major clinical trial (AREDS2), which is currently enrolling participants to study the impact of supplemental xanthophylls (FloraGLO® Lutein and zeaxanthin) and other nutrients on age-related eye health.5

In addition, a double-blind placebo controlled trial was performed in ninety individuals who had signs of compromised visual function. Individuals were divided into three groups and received either 10 mg FloraGLO® lutein, 10 mg FloraGLO® lutein plus a multivitamin/multimineral formulation, or placebo for 12 months. In both the FloraGLO® lutein and FloraGLO® lutein plus other nutrients groups, improvements were seen in mean eye macular pigment optical density, visual acuity and contrast sensitivity. No improvements were noted in the placebo group.6 These results demonstrate FloraGLO® lutein’s beneficial effect on maintaining healthy visual function.

Newly published research has demonstrated that lutein and zeaxanthin supplementation may enhance visual performance under glare conditions. Forty healthy subjects took daily doses of 10 mg FloraGLO® Lutein plus 2 mg zeaxanthin for six months. They were evaluated for changes in macular pigment, glare disability and photostress recovery at the onset of the study, and at 1, 2, 4 and six months. After six months, subjects experienced an average increase in macular pigment optical density (MPOD) of 39% compared to baseline, and all but two participants experienced some increase in MPOD. This increase in MPOD was also directly related to measured improvements in visual performance after exposure to bright light, as well as photostress recovery.7 This study suggests another way in which lutein and zeaxanthin can help support optimal visual function in healthy individuals.

Potent Antioxidant Protection*

Most of the beneficial effects of lutein are ascribed to its potent free radical scavenging abilities. It is well-known that lutein is a carotenoid related to beta-carotene and possesses antioxidant activity against a number of reactive oxygen species.8

More direct evidence for the free radical scavenging activity of lutein is found in studies of its effects on human lens epithelial cells. Cell cultures were exposed to ultraviolet light after pretreatment with lutein or alpha-tocopherol. Both nutrients were found to reduce ultraviolet-induced damage to lens epithelial cells. However, lutein was shown to have significantly higher photoprotective activity than alpha-tocopherol9 demonstrating its potential as a high-powered antioxidant.

A further review of the mechanisms of lutein in conferring a protective role reveals evidence for its antioxidant activity in various body tissues. Lutein has been shown to be an effective antioxidant in vitro as well as in experimental models of a number of body systems.10

Supports Healthy Skin*

A recent randomized, double blind, placebo-controlled study has demonstrated the positive effects of oral and topical administration of lutein on skin health parameters (surface lipids, hydration, photoprotective activity, skin elasticity and skin lipid peroxidation). Forty female subjects were divided into four treatment groups. Treatment options included oral administration of 5 mg of FloraGLO® Lutein twice daily or placebo and topical administration of 50 ppm FloraGLO® Lutein twice daily or placebo. Each treatment group received either an active oral treatment with a placebo topical treatment, a placebo oral treatment with an active topical treatment, both active treatments, or both placebo treatments. Statistically significant improvements were seen in all five parameters tested in all treatment groups compared to the group receiving only placebos. The greatest overall improvements were seen in the group receiving both active oral and topical treatments, while lesser but still significant improvement was seen in both the active oral only and the active topical only groups. Additionally, oral administration of lutein conferred superior photoprotective activity (as measured by skin surface redness after exposure to ultraviolet light) and prevention of lipid peroxidation (as indicated by levels of malondialdehyde in skin lipids after exposure to ultraviolet light) than either topical lutein or placebo.11

Diverse Cinical Benefits*

Evidence from various experimental trials suggests that lutein may play a protective role on the circulatory and cardiovascular systems. Its antioxidant activity may also extend to the heart, skin, lungs and blood vessels, making it a nutrient with diverse clinical benefits. Lutein possesses the ability to promote the health of many body tissues.12

Lutein - A plant pigment provides sun protection from the inside out.

Subject: Lutein - A plant pigment provides sun protection from the inside out.

A plant pigment provides sun protection from the inside out.

 

Energy on earth begins with the sun’s rays, which spark the photosynthesis in plants that ultimately powers all life. (Petroleum is the residue of prehistoric plants crushed over eons into liquid form.) But the sun’s energy is not totally benign for us humans; excess exposure can cause skin to wrinkle and eyesight to dim.

 

Enter lutein. This plant chemical, reddish-orange like the setting sun, has become a hot commodity over the past several years because of its ability to protect both eyes and skin against sun damage. A member of the carotenoid family of nutrients, lutein is generally paired with its partner, Zeaxanthin, in a wide variety of foods, including egg yolks, fruits, corn and leafy greens such as spinach (where its bright color is masked by the green of chlorophyll). That’s a good thing, since your body can’t make lutein and so needs to obtain it from your diet.

 

Skin Shield

 

The sun produces a whole spectrum of light rays, from the visible (red through violet) to the invisible or ultraviolet (UV). UV rays—both ultraviolet-A (UVA) and ultraviolet-B (UVB)—are troublemakers. They attack collagen, the protein that gives skin its shape, which leads to wrinkles and other signs of aging. What’s worse, UV is also capable of damaging skin cell DNA, a process that can promote cancer development. And UV isn’t the only culprit: The sun’s visible blue rays are believed to help create harmful molecules called free radicals within the skin.

 

The clue to lutein’s importance in fending off skin damage lies in the fact that it is found throughout both the outer (epidermis) and inner (dermis) skin layers, where as an antioxidant it fights free radicals and as an orange pigment it soaks up blue light. In one study, using lutein both orally and topically produced improvements in skin hydration and suppleness (Skin Pharmacology and Physiology 4/19/07). Lutein has also shown an ability to counter the inflammation and immune system suppression associated with excess UV exposure (Journal of Investigative Dermatology 2/04).

 

Lutein Gleanings

 

What is it? A red orange carotenoid found in a number of fruits and vegetables, generally with a similar compound called Zeaxanthin.

 

What does it do? This powerful antioxidant helps protect the eyes against both cataracts and age-related macular degeneration (AMD); it also appears to defend the skin against sun damage and has been associated with reduced arterial wall thickness, a measure of cardiovascular health.

 

The Eyes Have It

 

Your eyes, like your skin, are directly exposed to the sun’s UV rays. Such exposure can cloud the eye’s lens to create cataracts. It can also disrupt the retina at the back of the eye particularly the macula, the part of the retina responsible for clear central vision—which can result in age-related macular degeneration.

 

Not surprisingly, the eye is yet another one of the body’s lutein hot spots. This pigment is especially concentrated in the macula; in fact, of the 600 or so carotenoids that exist in nature, only lutein and Zeaxanthin are found within this all important structure. So it also isn’t surprising to learn that they Eye Disease Case Control Study, one of the first large-scale investigations into carotenoids and eye health, found a link between reduced AMD risk and high levels of lutein and Zeaxanthin. Current research has focused on the use of supplemental lutein in AMD patients, with promising results.

 

It isn’t only the outside of your body that may benefit from lutein. When oxidized by free radicals, LDL cholesterol settles into arterial walls. Lutein may help slow this process; in one study, people with the most lutein in their blood had 80% less vessel-wall thickening than those with the least (circulation 6/19/01).

 

So enjoy some fun in the sun. But respect the power of those golden rays, and let lutein help make playtime a safe time. –Lisa James.

Lutein to fight age-related macular degeneration!

Lutein: The Antiordinary Antioxidant

Lutein belongs to a class of compounds known as carotenoids. Carotenoids in general are yellow, orange, or red pigments responsible for many of the colors of the foods we consume each day. To date, over 600 carotenoids have been identified in nature, but are only produced by plants, algae and bacteria leaving humans and animals to consume carotenoids in the diet. Forty to fifty carotenoids are consumed in the typical US diet, but only 14 have been detected in the blood, indicating a selective use of specific carotenoids by the body. Lutein is one of these carotenoids found in the blood and has been increasingly associated with eye health over the last decade.

Lutein’s role in eye health

In the human eye, lutein is concentrated in the center of the retina in an area known as the macula. Lutein is deposited in the macula through the lutein we consume in out diet or through supplements. This area is responsible for human central vision and is colored intensely yellow due to high concentrations of lutein. Lutein is thought to be beneficial for eye health by reducing damage in the eye in two ways: 1) by absorbing blue light (blue light is thought to increase free radical formation in the eye) and 2) by acting as an antioxidant, reducing damage in the eye caused by free radicals. Leading carotenoid researchers believe these functions may lead to a reduced risk of age-related macular degeneration (AMD) and cataracts.

Age-related macular degeneration

Macular degeneration is the leading cause of blindness in the USA in those over 65. twenty-five and thirty million people are afflicted worldwide and currently there are no effective treatments for the disease. The disease has two forms known as dry and wet AMD.

Ninety percent of AMD cases diagnosed are the dry form. In dry AMD, also referred to as early AMD, debris deposits under the center of the retina (known as the macula) interfering with its normal function. Parts of the macula atrophy, causing the central vision to slowly become dimmer or more blurry. Wet age-related macular degeneration, also known as late AMD, often develops in areas where dry AMD exists. Abnormal blood vessels grow and leak blood and fluid under the macula, causing scarring, which leads to rapid loss of central vision.

Dr. Joanna Seddon published one of the first studies demonstrating a link between lutein intake and AMD risk in 1994 (1). This epidemiological study compared the risk of developing AMD to nutrient intake and showed a significant reduction in risk for developing AMD as lutein intake reached 6mg per day (57% reduction in risk). Since the Seddon study, researchers have shown that increasing dietary lutein intake raises blood levels of lutein as well as levels of lutein in the eye (2). Bone et al. demonstrated that eyes with higher levels of lutein were less likely to be afflicted with AMD (3).

The latest clinical trial that investigated lutein’s role in AMD is known as the lutein antioxidant supplementation trial (L.A.S.T) (4). This study evaluated the effects of lutein supplementation for one year in 90 veterans diagnosed with dry AMD. Supplementation with lutein in these subjects significantly increased the concentration of lutein in the macula. Improvements in visual function were also detected with lutein supplementation. Glare recovery, visual acuity, and contrast sensitivity were all improved. This study continues to build on clinical evidence that the dry form of AMD may be responsive to changes in nutrition.

Cataracts

A cataract is a natural clouding of the lens, the area of the eye responsible for focusing light and producing clear, sharp images. For most people, cataracts are a natural result of aging. Currently in the US, cataracts are the second leading cause of blindness in the elderly behind AMD.

Lutein is the major carotenoid that has been identified in the human lens asn is thought to provide similar benefits to the leans that are seen in the retina. Two large epidemiological studies consisting of >70,000 women (age 45-71) and >30,000 men (age 45-75) compared the risk of cataract extraction to nutrient intake (5,6). Similar to AMD, a significant reduction in risk of cataract extraction was associated with lutein intakes of 6mg per day (20% reduction in risk). Besides cataract extraction, higher levels of lutein consumption have been associated with a decreased risk of cataract development and improvements in visual acuity and glare sensitivity in people with age-related cataracts.

Lutein consumption

The richest source of free lutein in the typical US diet are dark green leafy vegetables, with the highest concentration found in kale followed by spinach.

The average daily lutein intake is low, average between 1-2 mg/day. Currently there is no recommendations of the dietary guidelines for Americans 2005 (9 servings of fruits and vegetables every day) you would consume between 4 and 8 mg of lutein a day (7). Epidemiological evidence, animal models, and clinical data have indicated levels of 6-10 mg a day may be necessary to realize the health benefits associated with lutein consumption. By continuing to increase our intake of lutein, we begin to ensure the optimal health of our eyes.

Plasma lutein concentrations were measured at 4-week intervals. During the course of the study, plasma levels increased five-fold from pre-supplement measures. It was also shown that macular pigment density increased by an average of 5.3% after 4 weeks due to increased deposition of lutein in optical tissues.1

A second study compared the oral bioavailability of esterified lutein, the form in Best Lutein, versus non-esterified lutein in 18 human volunteers. Serum levels of lutein were measured at particular timepoints after consumption of a single dose of lutein. Researchers found that in these individuals, the lutein ester formulation was nearly 62% more bioavailable than non-esterified lutein, as determined by a higher mean area under the curve (AUC) and higher serum concentrations.2

A study was also conducted to investigate the possible role of specific nutrients in protecting the lens of the eye against aging, a risk factor for compromised visual function. The study was comprised of 376 individuals aged from 18 to 75. Of the nutrients measured, it was found that the lenses of individuals with higher concentrations of lutein and zeaxanthin showed less of an effect from the aging process. The investigators concluded that these carotenoids may play a protective role in supporting the maintenance of healthy vision.3

In addition, a double-blind placebo controlled trial was performed in ninety individuals who had signs of compromised visual function. Individuals were divided into three groups and received either 10 mg lutein, 10 mg lutein plus a multivitamin/multimineral formulation, or placebo for 12 months. In both the lutein and lutein plus other nutrients groups, improvements were seen in mean eye macular pigment optical density, visual acuity and contrast sensitivity. No improvements were noted in the placebo group.4 These results demonstrate lutein’s beneficial effect on maintaining healthy visual function.

Subject: Antioxidants

Antioxidants By Ellen J. Kamhi, Ph. D. with Dorie Greenblatt Antioxidants. A term we hear often, but do we really pay attention to the enormous role these substances play in our systems? And what are they exactly anyhow? Where do they come from and how do they work?

Antioxidants are a group of naturally occurring vitamins, minerals and enzymes found in plant foods. These vital substances help to protect our cells from free radicals, the culprits responsible for causing damage to our bodies very quickly.

Free radicals are groups of unstable atoms looking to obtain electrons in order to become stable themselves. They can pull electrons off cell membranes, causing the cell membranes to have free radical activity as well. This unleashes a vicious cycle of cell destruction, known as a “free radical cascade.” Free radical damage is linked to a plethora of diseases. Luckily there are literally thousands of antioxidants to help us win the “free radical battle”.

Antioxidants can be differentiated by their colors. Those of a red, orange or yellowish color fall into the group known as carotenoids, while those with a blue, purple, black color are from the phenolic family. Of course, there are also some yellow green phenolics too, like the polyphenols from Green Tea.

The carotenoid group of antioxidants are fat-soluble and therefore offer protection for the fat containing parts of the body. This is especially useful in protecting our lipid containing cell membranes. These carotenoids hang out in our membranes, thereby protecting them from free radical damage. What’s even more important is the ability of carotenoids to enhance the activity of other fat-soluble antioxidants such as vitamins A, E and Co Q-10. Some of the best carotenoid sources are lycopene, curcumin and lutein.

Lycopene, a red carotenoid derived from tomatoes, has been shown to contain strong protection capabilities against free radical damage. Curcumin, a yellow carotenoid from turmeric, displays a more protective antioxidant activity than that of Vitamin E or Vitamin A in protecting DNA breakdown (by free oxygen). It also serves as a potent anti-inflammatory agent. Lutein, another carotenoid antioxidant, is a primary component of the retina and macula areas of the eye. Lutein’s antioxidant properties may help protect the macula from light induced free radicals. Evidence shows it may help reduce the risk of age related macular degeneration as well.

The phenolic groups are the water-soluble antioxidants. This group protects the blood, lymph and other bodily fluids, as well as the organs containing those fluids. Some of the best phenolic antioxidants are those found in Green Tea, particularly a group known as catechins. Catechins have proven to have immune- enhancing benefits. Another family of important phenolic antioxidants are those called anthocyanins. These too have proven to act to protect the immune system. Finally, we can’t forget one of the best-known water-soluble antioxidants: Vitamin C !

The need for antioxidants is widespread. We normally think of smokers as the primary group who would most benefit from antioxidants, but the truth is that anyone under stress is a prime candidate for taking antioxidants. In addition, anyone who carries a strenuous physical or mental work load or who exercises often needs the protection of antioxidants, since free radical levels are increased by an active metabolism. And, of course, those individuals who don’t consume enough fruits and vegetables in their diet should also consider using a well-rounded antioxidant formula.

Nature’s Answer offers an outstanding selection of antioxidant formulas available in liquid and/or capsule form. These include Lycopene and Green Tea Extracts (liquid, softgel and vegetarian capsule), Bio-Flavonoids & Rose Hips (low organic alcohol liquid herbal extract) and Grape Seed Extract (vegetarian capsule). For a well-balanced potent antioxidant blend, try Antioxidant Supreme™, a standardized herbal extract formula containing the best of the carotenoid and phenolic antioxidants in one convenient vegetarian capsule. This formula, in particular, provides concentrated natural sources of antioxidants for “supreme” overall protection.
