Can anyone help resolve a debate?

Is there any robust scientific evidence that organic food has more
vitamins and/or minerals in it that normal food?

And/or that it is any better for you as a result?

If so, I need the scientific references to convince my friend...

Department of Internal Medicine, University of Texas at Houston.

Thrombosis of the coronary arteries, heart chambers, and great vessels
is a complication of polycythemia.
Previously, the treatment of coronary thrombosis in the presence of
this disease was based on exchange phlebotomy.
However, the development of efficient thrombolytic agents, emergency
catheterization techniques, and coronary artery bypass surgery may
make phlebotomy obsolete.

Ghaffari S
Antioxid Redox Signal 2008 Aug 15.

Recent evidence suggests that oxidative stress contributes
significantly to the regulation of hematopoietic cell homeostasis.
In particular, red blood cells and hematopoietic stem cells are highly
sensitive to deregulated accumulation of reactive oxygen species
(ROS).
Unchecked ROS accumulation often leads to hemolysis, that is, to
destruction and shortened life span of red blood cells.
In addition, the process of erythroid cell formation is sensitive to
ROS accumulation.
Similarly, ROS buildup in hematopoietic stem cells compromises their
function as a result of potential damage to their DNA leading to loss
of quiescence and alterations of hematopoietic stem cell cycling.
These abnormalities may lead to accelerated aging of hematopoietic
stem cells or to hematopoietic malignancies.

In postmenopausal women, low serum vitamin D concentrations were associated
with an increased risk for hip fracture in a nested case-control study here.

Women with the lowest serum concentrations of 25-hydroxyvitamin D were 71%%
more likely to have a hip fracture than those with the highest (OR 1.71, 95%%
CI 1.05 to 2.79), Jane Cauley, Dr.P.H., of the University of Pittsburgh, and
colleagues, reported in the Aug. 19 issue of Annals of Internal Medicine.

Adjusting for C-terminal telopeptide of type I collagen -- a marker for bone
resorption -- seemed to eliminate the association (OR 1.58, 95%% CI 0.97 to
2.60), the researchers said, but the overall trend remained significant in a
multivariate model (P=0.029).

"Our findings suggest that low serum 25-hydroxyvitamin D concentrations
might help identify women at high risk for hip fracture," they said.

Past studies examining the link between serum vitamin D concentrations and
risk of fracture have yielded mixed results, they said.

To explore the issue, the researchers turned to the Women's Health
Initiative Observational Study, a large prospective cohort study of
participants ages 50 to 79.

They selected 400 women who had an incident hip fracture and 400 controls
from 40 clinical centers around the U.S. for a case-control study nested
within the larger study.

All of the participants were postmenopausal (mean age 71, 95%% white) and
were not using estrogens or other osteoporosis medications.

Serum vitamin D concentrations were measured at baseline and the
participants were followed annually with questionnaires for a mean of 7.1
years (range 0.7 to 9.3).

At baseline, concentrations were lower in the case patients than in the
controls (55.95 nmol/L versus 59.60 nmol/L, P=0.007).

For each 25-nmol/L decrease in vitamin D concentration, the risk of hip
fracture was increased by 33%% (OR 1.33, 95%% CI 1.06 to 1.68).

Risk of hip fracture decreased significantly from women in the lowest
quartile of vitamin D concentration (< 47.5 nmol/L) to those in the highest
(> 70.7 nmol/L) (P=0.016 for trend).

College presidents from about 100 of
the nation's best-known universities,
wish "an informed and dispassionate
debate" over the issue of drinking age.

Consider the human brain and computers.
http://en.wikipedia.org/wiki/Human_brain#Comparison_of_the_brain_and_a_computer

Allowing alcoholism on campus by
lowering the drinking age, equals
inserting into the human brain, the
equivalent of an informed consent
malware program, into a sophisticated
stand alone computer system. Malware
is a legal form of computer contaminant.
http://www.ncsl.org/programs/lis/cip/viruslaws.htm

"The human brain is also mediated
by chemicals and analog processes,
many of which are only understood
at a basic level and others of which
may not yet have been discovered,
so that a full description is not
yet available in science."

All college and university campus
facilities must be alcohol and
drug free, as a minimum requirement
for admission and school retention.
The degradation of human resources
and campus safety by university
approval: the antithesis of intelligence;
also, the antithesis of being an adult.

Respectfully yours,

Potential Alzheimer's, Parkinson's Cure Found In Century-old Drug
ScienceDaily (Aug. 18, 2008) — A new study conducted by researchers at
Children's Hospital & Research Center Oakland shows that a century-old
drug, methylene blue, may be able to slow or even cure Alzheimer's and
Parkinson's disease. Used at a very low concentration – about the
equivalent of a few raindrops in four Olympic-sized swimming pools of
water – the drug slows cellular aging and enhances mitochondrial
function, potentially allowing those with the diseases to live longer,
healthier lives.
A paper on the methylene blue study, conducted by Hani Atamna, PhD,
and a his team at Children's, was published in the March 2008 issue of
the Federation of American Societies for Experimental Biology (FASEB)
Journal. Dr. Atamna's research found that methylene blue can prevent
or slow the decline of mitochondrial function, specifically an
important enzyme called complex IV. Because mitochondria are the
principal suppliers of energy to all animal and human cells, their
healthy function is critical.

"The results are very encouraging," said Dr. Atamna. "We'd eventually
like to try to prevent the physical and cognitive decline associated
with aging, with a focus on people with Alzheimer's disease. One of
the key aspects of Alzheimer's disease is mitochondrial dysfunction,
specifically complex IV dysfunction, which methylene blue improves.
Our findings indicate that methylene blue, by enhancing mitochondrial
function, expands the mitochondrial reserve of the brain. Adequate
mitochondrial reserve is essential for preventing age-related
disorders such as Alzheimer's disease."

Also impressed is one of Dr. Atamna's co-authors, Bruce Ames, PhD, a
senior scientist at Children's and world-renowned expert in nutrition
and aging. "What we potentially have is a wonder drug." said Dr. Ames.
"To find that such a common and inexpensive drug can be used to
increase and prolong the quality of life by treating such serious
diseases is truly exciting."

Methylene blue, first discovered in 1891, is now used to treat
methemoglobinemia, a blood disorder. But because high concentrations
of methylene blue were known to damage the brain, no one thought to
experiment with low concentrations. Also, drugs such as methylene blue
do not easily reach the brain.

Dr. Atamna's research is the first to show that low concentrations of
the drug have the ability to slow cellular aging in cultured cells in
the laboratory and in live mice. He believes methylene blue has the
potential to become another commonplace low-cost treatment like
aspirin, prescribed as a blood thinner for people with heart
disorders.

Dr. Atamna's research, funded by the Bruce and Giovanna Ames
Foundation, was conducted at Children's research institute and will
continue when Dr. Atamna assumes a position as a professor of
Neuroscience at The Commonwealth Medical College in Pennsylvania.

Improvement in Storage Stability of Fish Fillet Using Dietary Soybean
Phospholipids

Soybean phospholipids are known to exhibit antioxidant effects on oils
and fats.
However, few studies have examined their antioxidant effects in vivo.
In this study, we investigated the influence of dietary soybean
phospholipids on fish fillet oxidation.
For 4 weeks, we fed rainbow trout diets containing 0, 1.0, or 2.5%%
soybean phospholipids, of which the lipid content was adjusted with
soybean oil.
We compared oxidation stability in fillets after the feeding period.
In the fillet of fish fed the soybean phospholipidcontaining diets,
the thiobarbituric acid reactive substance (TBARS) level following an
oxidation test was significantly inhibited compared to that in the
fillet of fish fed a soybean oil-containing diet.
Similarly, the syntheses of malondialdehyde (MDA) and 4-
hydroxyalkenals (HAE) were significantly inhibited.
These results suggest that the administration of soybean phospholipids
improves the storage stability of fish fillet.

Keywords: soybean phospholipids, oxidation, lipid, fish

Somehow those with lupus "DON'T have increased red blood cell
production and hemolysis / polycythemia / erythrocytosis / iron
overload " .. even though all markers say they doooo.

Thrombosis is high in lupus and it is proportional TO **the
hematocrit** .. higher red blood cells.

Higher the red blood cells the higher the coaguability and visa versa.

Excerpt: "The treatment of patients in the plethoric phase of the
disease is aimed at ameliorating symptoms and decreasing the risk of
thrombosis or bleeding by reducing the blood counts. The red count and
hematocrit can be controlled in some patients by periodic phlebotomy,
but administration of drugs that suppress marrow activity also is
required to control the platelet and white counts. Both treatment
modalities are used in most patients. Table 56-4 summarizes the
advantages and disadvantages of various forms of therapy.The usual
initial treatment for most patients is phlebotomy.50,238 The rationale
for phlebotomy therapy of polycythemia vera is based on a widely
quoted paper that suggested that the risk of thrombosis in
polycythemia vera was proportional to the elevation in hematocrit.239
The underlying mechanisms causing thrombosis in polycythemia vera are
not fully known, but the hematocrit likely is not the only, and may
not even be the principal, risk factor.
