(ARA) - By now you probably think you've
heard all of the health reasons there are for eating your vegetables.
But recently, researchers from Harvard University have announced that
lutein -- a potent antioxidant found in such dark green, leafy vegetables
as spinach and kale -- may protect the skin from sun damage.
"Lutein has been widely recognized for its
eye health benefits for several years. But, our data is the first of its
kind to suggest that lutein may have the potential to act as a preventative
agent against UVB-induced skin cancer," said Salvador Gonzalez, M.D.,
Ph.D., leader of the Harvard research team. "In addition, these data suggest
that lutein protects the skin against damage caused by exposure to UVB
light, further validating our position that lutein is a critical component
to overall skin health."
Lutein (LOO-teen) is a yellow pigment (the
yellow is covered up by chlorophyll in green leaves) found predominantly
in vegetables. It is also present in the eyes and skin of the human
body. In women, lutein is found in the breasts and cervix. As an antioxidant,
lutein protects the eyes from the damaging effects of aging. Lutein
also acts as a light filter, protecting against the sun's harmful rays.
UVA and UVB rays are two types of harmful
rays found in sunlight. UVA rays contribute to wrinkling the skin, as
well as to the development of skin cancer. UVB rays are the ones that
are the primary cause of sunburn and skin cancer.
Good sunscreens block both UVA and UVB rays
and are critical to skin health. But, you can do even more to protect your
skin and eyes when you're outside.
Safety tips to keep top of mind:
- Wear UV-blocking sunglasses. Over time,
exposure to ultraviolet light can cause cataracts and increase your risk
of macular degeneration, a disease that causes irreversible blindness.
- If you're a parent, protect your children's
skin. Research indicates that one or more severe, blistering sunburns
in childhood or adolescence can double the risk of skin cancer later
in life.
- Check the expiration date on your sunscreen.
Sunscreen without an expiration date has a shelf life of no more than
three years.
- Eat a healthy diet comprised of green
leafy vegetables. Consumption of 6 milligrams of lutein per day (approximately
one-third cup of cooked spinach) has been linked to a reduced risk of
cataracts and age-related macular degeneration. Vitamins and dietary
supplements formulated with purified lutein provide another option for
adding this nutrient to a daily diet.
It's important to note that when lutein
is consumed in foods or vitamins, it deposits in various tissues in the
body -- the eyes, the skin, fat tissue and so on. Therefore, it may also
be beneficial to apply lutein directly to the surface of your skin. Several
skin care products containing lutein are now available and can be purchased
online at www.sephora.com
or at salons that carry California Tan Heliotherapy sun care products.
