Lutein: Can it Lower Risk of Heart Disease?
People with higher levels of lutein in their blood also have healthier (i.e., less clogged) arteries. Lutein contains carotenoids, which have shown beneficial effects in reducing the risk of cancer, heart disease and eye disease, and in enhancing the body’s immune response.
Lutein is a yellow pigment found in egg yolks, spinach, collard greens, kale, broccoli, Brussels sprouts, cantaloupe, and oranges. It is part of the carotenoid family of nutrients. The artery-protective nature of lutein is yet one more reason why a diet rich in fruits and vegetables can help prevent heart disease.
How much lutein do we need?
Research suggests a minimum of 6 to 10 mg per day of lutein from dark green leafy vegetables. This much is required to realize its health benefits. Even if you eat a balanced diet, you’d need a large bowl of fresh spinach to get about 6 mg. Most Americans just don’t consume enough foods rich in lutein.
Tip: If you are not a vegetable-lover, try chopping up some kale or spinach and adding it to spaghetti sauce or meat loaf. You will not taste it, but you will still get all its benefits.
Helps Computer Eyes
A study from Beijing research, published in the British Journal of Nutrition, has noted improvements in the sensitivity to contrast on a computer screen in subjects taking lutein! Thirty-seven healthy subjects between the ages of 22 and 30 with long-term computer display light exposure were studied. The subjects were observed following 12 weeks of supplementation. There was a trend towards improved visual acuity and measures of contrast sensitivity in the subjects taking the supplement verse the placebo group.
Lutein is available in nutritional supplements for people wanting to supplement their dietary intake. Make your diet even better for your eyes and skin. Nature’s Bounty Lutein naturally contains zeaxanthin and promotes good eye health.
