Cataracts and Natural Preventative Measures
Some people believe cataracts are a contagious disease – this is false. Cataracts are simply the clouding of the eye’s lens. Inside of the eye there are large numbers of small proteins called crystalline. As individuals age the crystalline proteins age as well. They form protein clumps on the lens of eye which block light from objects from completely entering the eye. When the light is blocked the vision that the individual sees is blurry, fuzzy and faded.
There are many reasons for the aging of the crystalline proteins, some of which may be preventable. Cataract formation factors include:
- Free radical damage
- UV exposure
- Diabetes and obesity
- Long term use of corticosteroids
Free Radical Damage
– Free radicals are scavenger
molecules in the body which are
on the constant prowl for an
extra electron molecule.
Most often they will swipe an
electron from a healthy
substance which in turn will
become damaged and is usually
destroyed.
In the lens of the eyes, the crystalline proteins are the ones that are quite frequently damaged by the actions of these free radicals. However, there are numerous steps that can be taken to limit the quantities of free radicals within the body in the first place.
- Consume larger amounts of antioxidants. Antioxidants can be found in fresh fruits and vegetables. Major players include lutein and zeaxanthin (both known as carotenoids). They are present in eggs, most green vegetables, and squash.
- Antioxidants can also be ingested through supplementation of Vitamins C, E and A, along with the trace mineral selenium. A good multi-vitamin should suffice.
- Stop smoking and only
consume alcohol in
moderation. Both can
increase the levels of free
radicals in the body.
UV Exposure
– Exposing unprotected eyes to
direct UV light is a no-no.
The UV rays can increase the
deterioration rate of the
proteins of the eyes.
Additionally, UV rays have been
implicated in the formation of
free radicals as they tend to
“oxidize” certain molecules
within the body. When out
in the sun, especially during
the middle of the day, wear
sunglasses with UV protection.
Diabetes and Obesity
– One of the leading risk
factors of cataract formation is
the presence of an additional
underlying disease such as
diabetes. As obesity is
the leading risk factor in
developing diabetes it, too,
must be controlled in order to
keep the incident of cataract
formation at a low level.
Diabetes tends to increase levels of sorbitol within the blood. Researchers believe that sorbitol
can negatively affect the lens
of the eye and eventually lead
to the development of cataracts.
In addition,
in patients with diabetes, the
capillaries to the eyes can
become damaged. When this
occurs the quantity of nutrients
arriving to the eye decreases
and the levels of toxins and
waste materials which can no
longer leave the eye accumulate
in the region. All of this
impacts the eye and the lens
negatively.
Following a healthy, nutritious and whole foods diet along with getting adequate levels of exercise each day will greatly decrease the chance of developing diabetes and becoming obese and subsequently will lower the risk of developing cataracts.
Long Term Use of Corticosteroids
– Several recent studies have
pointed out the correlation of
using corticosteroids over a
long period and the increased
risk of developing cataracts.
A problem arises for asthmatic
patients who sometimes depend on
inhaled corticosteroids to
maintain functional breathing!
Researchers are now looking
further into the problem and
assessing the situation.
In some cases there may be
alternate drugs which will
suffice for the asthmatic
patient while in other cases
decreased use of inhaled
corticosteroids may be
suggested. However, it is
NEVER wise to discontinue any
form of medication without first
speaking with your doctor.
To sum it up, by following a healthy and well balanced diet, the risk factors associated with developing cataracts as we age may be greatly diminished.
