Vitamin C Essential for Good Health

The benefits of Vitamin C go beyond the generally known relieve of colds and flu.
It also helps the body to make collagen, a tough, fibrous protein that helps to build
connective tissue, skin, bones, and teeth, and it also plays a role in wound healing.

There is also some evidence that foods high in vitamin C and other antioxidants can
reduce the inflammation from asthma and return the airways to normal.
I refer to Nutrition Facts.org and my page: nutrition

Osteoarthritis
Doctors believed for many years that osteoarthritis was a “natural” result of wear an tear
on the joints. Researchers at the Boston University School of Medicine studied the eating
habits of people with osteoarthritis of the knee. They found that those getting the most
vitamin C – more than 200 milligrams per day – were three times less likely to have the
disease get worse than those who got the least.

Cancer
Vitamin C also has been shown to help prevent cancer-causing compounds from forming
in the digestive tract. Gladys Block PhD, professor of epidemiology and public health
nutrition at the University of California, Berkeley, analyzed dozens of studies that looked
at the relationship between vitamin C and cancer. From the 44 studies she examined, 33
showed that people who consumed the most of this vitamin  had the lowest risk of cancer.

Diabetes
If you have diabetes, fruits and vegetables rich in vitamin C and E may be your ticket to healthier eyes, nerves, and blood vessels.These vitamins are known as antioxidants.
They help protect your body’s cells against free radicals, naturally occur  cell-damaging
molecules that may pose particular risks to people with diabetes.

Rheumatism
People who are suffering from rheumatism also need Vitamin C
This vitamin strengthens the connective tissue which hold the cells together.
Connective tissue forms the sinews, ligaments, and cartilage of the body.
When this vitamin is lacking, the connective tissue loses its tone and loses its defense
against harmful bacteria and viruses.
Strong connective tissue protect the cells against infection.

Capillaries
Vitamin C also strengthens the blood vessel walls and it is the capillaries
that are affected most by a vitamin C deficiency.
When this happens, the capillaries break down and blood leaks from them
into the tissues. These tiny haemorrhages occur also in the joints, and
causes rheumatic pain. (When capillaries break near the surface of the skin,
the escaping blood discolors the skin and results in a bruise.
The capillaries exist in such an abundance in the human body, that if the
capillaries of one man were stretched out in a single line, they would reach
two and a half times around the earth!

With every type of disease the capillaries will be harmed and conversely,
by strengthening them, every diseased state will be helped.
The capillaries supply food, oxygen, and hormones to every cell in the body.
They also remove waste products from metabolism and disease.
When the capillaries are strong, the risk of infection is greatly reduced and
infections are quickly thrown off.

Male Infertility
If men don’t get enough vitamin C,  sperm lose some of their forward momentum.
They get sticky and start clumping together, a  problem doctors call agglutination.
Once men start getting more vitamin C, however, sperm increase in number   and
quickly pick up speed.

Smokers
Getting more vitamin C is particularly important for men who smoke.
Studies have shown that smokers who get extra vitamin C in their diets  will have
healthier, more active sperm than those who don’t.

Vitamin C is also essential for healthy bone formation and people suffering
from hay fever may also benefit.

Sources of Vitamin C are broccoli  , a half cup contains 58 milligrams,
a half cup cantaloupe contains 34 milligrams and a medium-size navel orange
has 80 milligrams , which is 133% of the Daily Allowance .

 

Problems Concerning the Eyes

Cataract surgery is most common for people over the age
of sixty In the US, eye surgeons perform 1.3 million cataract
operations every year for a total cost of US $3.5 billion.

The lens of the eye collects and focus light on the retina.
It is important for the lens to stay clear throughout our lifetime,
In order to function properly. As we age, various components
of the lens may get damaged, leading to cataracts.

Medical research has proven that supply of sufficient anti-
oxidants at an early age can prevent cataract formation.
Antioxidants are needed to combat against free radicals,
due to ultraviolet sunlight.

In particular the fluid around the lens of the eye has to be
protected by antioxidants against oxidative damage.
The most important antioxidant is vitamin C, which is found
in high concentration around the lens, as well as vitamin E,
alpha-lipoic acid and beta-carotine.

A study showed that consuming vitamins in supplementation
protects the eye and decrease the risk of developing
cataracts by 50%. There is sufficient evidence that taking
antioxidants is an inexpensive way to decrease cataract
formation.

Another problem concerning the eye is macular degeneration.
It is the leading cause of blindness in people over the age of
sixty.

This is the decay of an important part of the retina called
macula. This is the area, which deals with central vision,
where the greatest concentration of photoreceptors are located.

We recoqnize wet and dry forms. Ninety percent of the cases
represent the dry form, in which central vision gradually
reduces and may proceed to the wet form for the remaining
ten percent.

There is currently no treatment available for the dry form.
The wet form can be treated via laser photocoagulation,
by which new vessel formation can be slowed down, which
causes swelling and bleeding into the retina.
Blindness usually follows rather quickly.

Theories suggest that light entering the eye and focused on
the macula of the retina causes significant free-radical
production in the outer aspect of the photoreceptors.

If there are no sufficient antioxidants available to the
photoreceptors, lipofuscin formation, a toxic substance,
within the retinal pigment epithelium, causes more oxidation
damage to the retina and research believe it is actually
the cause of damage and destruction of these sensitive
photoreceptors.

Lipofuscin accumulate in the pigment epithelium cells and
are eventually excreted in the form of drusen, which is one
of the first indications of macular degeneration development.

The development of drusen separates the photoreceptors
of the eye from its blood supply and causes an area of
blindness.

High-energy ultraviolet light and visible blue light are in
particular responsible for the production of free radicals
in the retina of the eye.

Our natural antioxidant defence system that protects us from
this free radical damage, declines when we get older.
Macular degeneration is characterised by low levels of zinc,
selinium, vitamin C, vitamin E and carotenoid.

High levels of carotenoids, called lutein and zeaxanthine,
absorb the blue light portion of visible light, that can damage
the lens and he retina of the eye. They are strong antioxidants
and are found in corn and leafy green vegetables.

CoQ10 can also play a part in reducing the oxidative damage
caused by free radicals.

Glutathione, which is a very potent antioxidant found within
every cell of our body, is in particular critical within the lens of
our eye and the pigment and the photoreceptor cells of the
retina. The level of glutathione declines when we get older.

Glutathione peroxidase is one of the natural antioxidant
defencesystems that our body creates. The nutrients needed
for the body to make its own defense are selinium, vitamin B6,
N-acetyl-L-cysteine and niacin.

Vitamin C and alpha-lipoic acid have the ability to regenerate
glutathione. Zinc is important for the function of our catalase
antioxidant defense system and selinium is necessary for the
glutathione peroidase system and both are important to
combat free radicals produced in the eye.

As we get older, the lens of our eyes allows more ultraviolet
light through and no longer protects the retina from damage
of ultraviolet light. A good quality pair of sunglasses that
block all UV light are important.

Without any doubt, the underlying cause of cataracts and
macular degeneration is oxidative stress.
Consequently, we can’t be too agressive in our
supplementation plan.
