Fish Oil Protects Against Diseases Like Parkinson's
ScienceDaily
(Apr. 20, 2009) — Dr. Nicolas Bazan, Director of the Neuroscience
Center of Excellence, Boyd Professor, and Ernest C. and Yvette C.
Villere Chair of Retinal Degenerative Diseases Research at LSU Health
Sciences Center New Orleans, will present new research findings showing
that an omega three fatty acid in the diet protects brain cells by
preventing the misfolding of a protein resulting from a gene mutation
in neurodegenerative diseases like Parkinson's and Huntington's.
He
will present these findings for the first time on April 19, 2009 at the
Ernest N. Morial Convention Center, Nouvelle C Room, at the American
Society for Nutrition, Experimental Biology 2009 Annual Meeting.
With
funding from the National Eye Institute of the National Institutes of
Health, Dr. Bazan and his colleagues developed a cell model with a
mutation of the Ataxin-1 gene. The defective Ataxin-1 gene induces the
misfolding of the protein produced by the gene. These misshapened
proteins cannot be properly processed by the cell machinery, resulting
in tangled clumps of toxic protein that eventually kill the cell.
Spinocerebellar Ataxia, a disabling disorder that affects speech, eye
movement, and hand coordination at early ages of life, is one disorder
resulting from the Ataxin-1 misfolding defect. The research team led by
Dr. Bazan found that the omega three fatty acid, docosahexaenoic acid
(DHA), protects cells from this defect.
Dr. Bazan's laboratory
discovered earlier that neuroprotectin D1 (NPD1), a naturally-occurring
molecule in the human brain that is derived from DHA also promotes
brain cell survival. In this system NPD1 is capable of rescue the dying
cells with the pathological type of Ataxin-1, keeping their integrity
intact.
"These experiments provide proof of principle that
neuroprotectin D1 can be applied therapeutically to combat various
neurodegenerative diseases," says Dr. Bazan. "Furthermore, this study
provides the basis of new therapeutic approaches to manipulate retinal
pigment epithelial cells to be used as a source of NPD1 to treat
patients with disorders characterized by this mutation like
Parkinson's, Retinitis Pigmentosa and some forms of Alzheimer's
Disease."
Vitamins Found to Prevent Disease

Vitamins - Small Complex Nutrients Found in Food
Major Players in Maintaining Good Health

Vitamin Choices, Linda Mundorff
In
the body, vitamins play a vital role, from aiding in the production of
blood cells, hormones, and energy, to boosting the immune system and
preventing disease.
Vitamins are organic or carbon-based
compounds that are necessary for normal function, growth, and
maintenance of body tissue. Vitamins are categorized as either
water-soluble (vitamins B and C,) or fat-soluble (vitamins A, D, E, and
K) . Water soluble vitamins are not stored in the body and must be
replaced daily while fat-soluble vitamins are stored, and depending on
individual needs, daily replacement may not be necessary.
Role of Vitamins
Vitamins have many functions within the body, some vitamins:
* Are required to breakdown foods during digestion
* Are necessary to produce blood cells
* Assist in the formation of hormones
* Participate in energy-producing reactions
* Boost the immune system
Vitamin Preservation
To
get the full benefit of vitamins, especially the water-soluble ones,
foods should be eaten as close to whole and natural as possible. For
example, produce that is eaten close to harvest has the highest vitamin
content, than produce that must travel long distances to get to your
grocery store. In addition vitamins can be lost due to improper
handling or storage, such as being exposed to air, light, heat, and
alkalinity (neutralization of acids).
Natural vs. Synthetic
In
nature, vitamins come from a variety of foods such as B vitamins which
are predominately found in dark green leafy vegetables while Vitamin E
is found in vegetable oils, nuts, and wheat germ. Attempting to
memorize the various dietary sources of all vitamins is not necessary
as The National Institute of Health has an excellent reference site on
the Internet.
Basically, natural vitamins are extracted from
foods while synthetic vitamins are produced in a laboratory. Chemically
both are exactly the same and generally work the same within the body.
But there are exceptions such as in vitamin E which is twice as potent
in its natural form than its synthetic form, and conversely, folic acid
which is more potent in its synthetic form than in its natural form.
As
previously mentioned, attempting to capture all of the nutritional
benefits from food is sometimes difficult due to improper handling and
storage. But there are issues related to synthetic vitamins as well,
for example, not all vitamins are created the same. Vitamin production
varies greatly, and one of the biggest issues is with chemical
substitutes that do not metabolize as well as the original, but are
easier and cheaper to produce.
As a consumer it is important to do the research and always read the label to:
* Determine how much active ingredient vs. additives or fillers are in the supplement.
* Determine the source of the dietary ingredient ( rose hips is one source for vitamin C)
* Check for type and amount of additives (gelatin, starch, stabilizers, and dyes)
* Dosage - how many pills are necessary per day to reach recommended requirement.
* Check for known potential allergens as you might be allergic to one of the inert ingredients.
Vitamin Deficiencies
Vitamin deficiencies usually happen over time and are almost always related to poor dietary intake:
* Insufficient intake of fruits and vegetables.
* Starvation diets.
* Meal replacements lacking proper vitamin supplementation.
* Cigarette smoking.
Also
important to note is that the symptoms related to deficiencies are not
always obvious, and sometimes are misdiagnosed. The most common
disorders related to deficiencies are:
* Scurvy > Vitamin C deficiency
* Beriberi > Vitamin B1 (thiamine) deficiency
* Rickets > Vitamin D deficiency
* Pellagra > Vitamin B3 (niacin) deficiency
Lastly,
when dietary intake of fat soluble vitamins is adequate and symptoms of
deficiencies are evident, one of two conditions might be the cause:
* Fat malabsorption syndrome (which blocks fat soluble vitamins from being absorbed) or
* A liver defect (that prevents the production of the proteins needed for vitamin transport).
Vitamins Found to Prevent Disease
Numerous studies have found promising results that certain vitamins might reduce the incidence of:
* Heart disease
* Parkinson's Disease
* Osteoporosis
* Neurological Disorders
* Aging Process
But
there have been numerous conflicting studies, as in The Oxford
University Clinical Trial Service that found daily doses of vitamins
had shown no improvement in heart disease, cancers, and cataracts,
among others.
In conclusion, vitamins are an important part of a healthy diet and provides many benefits to the overall function of the body.
13 Foods to Avoid

13 Foods To Avoid
As a doctor I have made it my mission to
educate as many people about the philosophical pitfalls of believing
"If it's on the shelf, it must be safe." In the US, we suffer from
something called the "shortest healthy lifespan". That means we spend
more years battling chronic disease than our peers from the 12
industrialized nations. There are many factors leading to this problem,
but one of the obvious is how loaded our diets are with artificial
chemicals.
1. Soda. Ahh, the good old American beverage. Soda is
everywhere. It is marketed hard, and found at birthday parties to
church functions. Nothing could be worse for the body than a splash of
insulin overloading sugar soup. Almost every person I counsel on weight
issues has a soda or diet soda addiction. (See also: The Top 10
Diseases Linked to Soda.)
2. Avoid Soy. Many patients in my
office ask about soy products. This article is designed to help uncover
some of the things many people are not aware of. Here is some of the
research on soy. A 2001 literature review suggested that women with
current or past breast cancer should be aware of the risks of potential
tumor growth when taking soy products, based on the effect of
phytoestrogens to promote breast cancer cell growth in animals.
A
study found high consumption of omega-6 polyunsaturated fatty acids,
which are found in most types of vegetable oil including soybean oil,
may increase the likelihood that postmenopausal women will develop
breast cancer. The most serious problem with soy may be its use in
infant formulas. "The amount of phytoestrogens that are in a day's
worth of soy infant formula equals 5 birth control pills," says Mary G.
Enig, Ph.D., president of the Maryland Nutritionists Association.
3.
Monosodium Glutamate. The word you need to know is excitotoxicity which
means too much activity, it is the pathological process by which nerve
cells are damaged and killed by glutamate and similar substances i.e.
(MSG). This occurs when receptors for the neurotransmitter are
bombarded and can cause excitotoxicity by allowing high levels of
calcium ions to enter the cell. Calcium influx into cells activates a
number of enzymes. These enzymes go on to damage cell structures such
as components of the cytoskeleton, membrane, and DNA.
Excitotoxicity
may be involved in spinal cord injury, stroke, traumatic brain injury
and neurodegenerative diseases of the central nervous system (CNS) such
as Multiple sclerosis, Alzheimer's disease, Amyotrophic lateral
sclerosis (ALS), Parkinson's disease, Alcoholism and Huntington's
disease. It's no wonder why the US leads the world in neurodegenerative
diseases. Millions of people consume this product and don't even know
the side affects.
4. Aspartame. It's a non-nutritive sweetener
about 180 times sweeter than sugar. When I speak, people invariably
want to argue this point. They want their artificial sweetener. I often
get comments like, "It's FDA approved." WARNING! WARNING! If the
government has to "approve" something for consumption THERE IS A
PROBLEM! It is simply approved until enough people die, than it will be
unapproved. Your health is your responsibility. Guard it well.
5.
Avoid High Fructose Corn Syrup. If you have seen any of the advertising
material for HFCS high-fructose corn syrup, the marketers are trying to
convince us this is a natural product. HFCS or crystalline fructose or
hydrolyzed fructose, it convert to triglycerides and adipose (fat)
tissue within one hour of consumption. The cheapest ingredient in the
processed food industry is HFCS. The sad part about this debate is not
whether HFCS cause problems, because that is settled with this research
article. The fact that mercury is found in 50% of products with HFCS
should be more of a concern to every parent.
6. Hydrogenated Oil
or Partially Hydrogenated Oil. Never buy foods with these ingredients
since they are trans fats. Trans fats are deadly, causes heart disease,
cause weight gain, and once more, other medical problems.
7.
Avoid Sugar. In fact, the sweetener seems to prompt the same chemical
changes in the brain seen in people who abuse drugs such as cocaine and
heroin. Sugar that is processed turns out as refined white powder.
8.
Don't Be Fooled By "Natural" and "Artificial Flavor". These words, most
of the time, mean that the food is loaded with chemicals and grown with
pesticides, chemical fertilizers, and herbicides. The bottom
line-eating organic food is best.
9. Avoid Artificial Color. If anything has dye in it, stay away. A dye is a chemical poison.
10.
Avoid Palm Oil. This is a very unhealthy oil that is cheap to
manufacture. It also has the wrong essential fatty acid ratio, which
means it increase the inflammation circulating in your blood.
Inflammation is being tied to almost all disease processes.
11.
Dextrose, Sucrose, and Fructose. There are chemically made sweeteners.
There are not good for the body at all. So, it's best to avoid them.
12.
Avoid Sucrulose and Splenda. This is a man-made sweetener that most
people have heard of. In spite of the hype, it is unnatural,
artificial, and man-made. The problems it can cause are increases in
appetite, depression, allergies, etc., all depending on the person's
genetic makeup. It is best to avoid these products.
13. No
Enriched Bleached White Flour. This flour has no fiber. It has no
nutritional value, and is highly refined. Eat organic wheat flour or
other organic flours such as rye, millet, etc. Shoot for 20 grams of
fiber a day.
