How To Prevent or Reverse Cataracts
What causes cataracts?
The answer is simple - dietary and metabolic
So what is a cataract?
A cataract is a dietary and/or metabolic acid
that has been buffered or chelated with an
alkaline buffer, such as calcium.
Simply stated a cataract is a stone in the eye.
How do you prevent or reverse cataracts?
Reduce acidity and increase alkalinity.
Women who have higher dietary intake of lutein and
zeaxanthin — compounds found in yellow or dark, leafy
vegetables and green fruits like avocado — as well as
more vitamin E from food and supplements appear to
have a lower risk for developing cataracts, according
to a report in the January issue of Archives of
Ophthalmology, one of the JAMA/Archives journals.
Because lutein and zeaxanthin are alkaline buffers
of dietary and metabolic acids.
“The oxidative hypothesis of cataract formation posits
that reactive oxygen species can damage lens proteins
and fiber cell membranes and that nutrients with
antioxidant capabilities can protect against these
changes,” the authors write as background information
in the article. Vitamin E, vitamin C, beta carotene,
lutein and zeaxanthin are all believed to have
antioxidant or anti-acid properties. Lutein and
zeaxanthin are the only carotenoids — yellow or green
plant pigments — present in the lens of the human eye
and may also protect against cataracts by buffering
dietary and metabolic acids.
William G. Christen, Sc.D., of Brigham & Women’s Hospital
and Harvard Medical School, Boston, and colleagues
analyzed dietary information from 35,551 female
health professionals who enrolled in the Women’s Health
Study in 1993. The women were then followed for an
average of 10 years, and the diets of those who
developed cataracts were compared with the diets of
those who did not.
A total of 2,031 women developed cataracts during the
study. When the participants were split into five groups
based on the amount of lutein and zeaxanthin they
consumed, those in the group who consumed the most
(about 6,716 micrograms per day) had an 18 percent
lower chance of developing cataracts than those who
consumed the least (1,177 micrograms per day). The
one-fifth who consumed the most vitamin E from food
and supplements — about 262.4 milligrams per day —
were 14 percent less likely than the one-fifth who
got the least (4.4 milligrams per day).
“In conclusion, these prospective data from a large
cohort of female health professionals indicate that
higher intakes of lutein/zeaxanthin and vitamin E are
associated with decreased risk of cataract,” the
authors write. “Although reliable data from randomized
trials are accumulating for vitamin E and other
antioxidant or anti-acid minerals and vitamins,
randomized trial data for lutein/zeaxanthin are
lacking. Such information will help to clarify the
benefits of supplemental use of lutein/zeaxanthin
and provide the most reliable evidence on which to
base public health recommendations for cataract
prevention by vitamin supplementation.”
According to Dr. Robert O. Young, a research
scientist at the pH Miracle Living Center, states,
"one of the best sources of lutein and zeaxanthin
is from avocado. Avocado is also a good source
of Vitamin E and other healthy oils that can help
reduce the formation of stones or cataracts by
reducing dietary and metabolic acids."
Here are just a few of the avocado products you
can choose from to increase dietary and
1) Freshly picked Rancho del Sol avocados the
day of your order.
2) Cold-pressed Rancho del Sol virgin avocado oil.
3) Low-heat dehydrated avocaodo powder with other
green veggies and fruits.
