People are worried
about losing their sight. As a remedy, ophthalmologists routinely prescribe
surgery over antioxidant nutrients to preserve sight. Due to the numerous
laser and surgical advances in the treatment of eye disorders, such as
retinal diseases, glaucoma, and cataracts, most eye doctors overlook nutrition
as a practical and successful solution to eye disease. Proper supplementation
and dietary changes can be a natural, viable, and economical approach
to preventing problems with and maintaining your precious vision!
You
probably know that Omega-3 oils protect your heart, but did you know that
they are crucial for sharp vision? Omega-3 oils found in such foods as
cold-water fish help regulate eye pressure, blood vessel elasticity, blood
thinning, and eye moisture, plus reduce eye spasms and sun sensitivity.
Omega-3 fats are also essential for strength, function, and nerve conduction
in the retina. Because they help reduce cholesterol, blood flows more
smoothly through the tiny blood vessels of the eye, enabling key nutrients
to reach the retina more easily.
To
ensure that you are getting enough of these important Omega-3 oils, I
suggest at least two meals of wild Alaskan salmon each week. Also take
a supplement of either cod liver or Omega-3 fish oils. These provide docosahexaenoic
acid (DHA), which is one of the most important Omega-3s to support vision.
Though flax is very good oil, it doesn’t provide DHA, thus simply
cannot afford you the same beneficial effects for your eyes as fish oil.
Another
detriment to our vision is macular degeneration. It is the leading cause
of blindness in our aging population and is divided into two types: wet
and dry. Wet macular degeneration, the less common, involves the creation
of new unwanted blood vessels, which begin to progress to the center of
the retina. This condition is the result of a blockage of oxygen to the
retina. It can progress in a matter of days. Dry macular degeneration
progresses more slowly and may be the result of vascular disease, damage
from ultraviolet rays, and low levels of antioxidants in the body. The
disease is defined as a progressive deterioration of the macula, the central
area of the retina. Most often occurring in people in their 70s, it robs
its victims of central vision, making reading impossible.
Risk
factors for macular degeneration include blue eyes (blue-eyed people are
20 times more at risk), excessive sun exposure, drusen or age spots in
the retina, smoking (which increases risk by two-and-ahalf times), as
well as a poor and high-fat diet.
A
key component of optimal eye health is a sufficient level of certain fat-soluble
antioxidants such as lutein. Lutein, a cousin of beta carotene and a great
nutritional preventive, can be attained by eating spinach, kale, collard,
mustard, and turnip greens. Six milligrams (mg) of lutein a day is the
equivalent of one-half
cup of cooked greens and can reduce your risk of this age-related retinal
disease by 43 percent. Now, scientists are experimenting with higher doses
of lutein, 30 mg a day, to see if damage to the macula can be reversed.
Early results are promising.
Other
fat-soluble antioxidants important for your eyes, include vitamin A and
beta carotene (25,000 IU—but don’t take more than 5,000 IU
if you are pregnant) and natural sources of vitamin E (400 IU) daily.
Blood thinners like heparin protect the macula. Natural blood thinners
are cayenne pepper, garlic, fish oils, and vitamin E. A daily dose of
zinc (30 mg) protects the eye from UV rays by raising melanin, a protective
pigment in the retina. Vision problems need not be a result of old age.
Beat the odds by giving your eyesight the support it deserves with a good
nutritional program.
