Oh, I agree. I don't think getting hung up on high fructose corn syrup
is good--saccharides, possibly. The other big issue, of course, and
undoubtedly as serious if not more so, is the "hydrogenated vegetable
oils" found in many foods.
(As to "natural" on a food label, just dismiss it out of hand. It
means nothing. In the US, though, "organic" on a FOOD label is
regulated by a relatively good law. By contrast, on a "personal care"
item like shampoo or toothpaste, it again lapses back into
meaninglessness.)
5,000 mg/kg injected peritoneally every five minutes. The results
shocked them! (LOL)
Seriously, no cite given but this comment:

"Some recent studies show "Rats normally live for a good two years,"
explains Meira Fields, Ph.D., research chemist at the USDA in
Beltsville, Maryland. "But the rats in my study fed a high-fructose,
low copper diets are dying after 5 weeks." One of the few human
studies of low-copper, high-fructose diets was abruptly stopped when 4
of the 24 subjects developed heart-related abnormalities, according to
Fields. High fructose diets have also been implicated in the
development of adult-onset diabetes. Fructose, especially when
combined with other sugars, reduces stores of chromium, a mineral
essential for maintaining balanced insulin levels, according to
Richard Anderson, Ph.D., lead scientist at the Human Nutrition
Research Center in Beltsville, Maryland."
Of course, I realize this site is trying to sell that bullshit coral
calcium crap. See the end for a couple of citations from Dr. Fields.
I don't think I found the specific study that they referenced above,
but a couple of interesting ones all the same.
There are more and more "convenience" foods made of increasingly
better ingredients and/or lacking the extra salt....there ya go, Tim!
Another source of trouble. If it says "fat free" it probably means
"salt" or "sugar loaded."
Oh, honey--do 4 too!!! It won't hurt and even a recent JAMA article
suggested all adult Americans could benefit! And I *KNOW* it is good
for people with chronic diseases like HIV and Hep C. (Topic!) Cites
abound! And it does NOT have to be expensive.
Sounds great! If you find a website, let me know. Us Untied States
folks seem to have been deprived of that, but our Public Broadcasting
has numerous cooking shows on the weekend. I like to cook.
Oh what the hell. Bon appetit!!
Hey--speaking of whom--my god! That woman has LIVED on pure fat for
6,000 years and she's STILL going strong, godlets bless her!!

Here the rats were killed at 4 weeks, so that might explain part of
their findings!

Dietary fructose but not starch is responsible for hyperlipidemia
associated with copper deficiency in rats: effect of high-fat diet.
Fields M, Lewis CG.
Nutrient Requirements and Functions Laboratory, Beltsville Human
Nutrition Research Center, ARS, United States Department of
Agriculture, Maryland 20705-2350, USA.
OBJECTIVE: To test the hypothesis that copper deficiency in rats may
be hyperlipidemic only when the diets consumed contain nutrients which
contribute to blood lipids such as fructose and high fat. METHODS:
Weanling male Sprague Dawley rats were fed diets which contained
either starch or fructose as their sole carbohydrate source. The diets
were either inadequate (0.6 microg Cu/g) or adequate (6.0 microg Cu/g)
in copper and contained either high (300 g/kg) or low (60 g/kg) fat.
At the end of the 4th week the rats were killed. Livers were analyzed
for copper content. Plasma was analyzed for cholesterol and
triglyceride concentrations. RESULTS: High-fat diet did not increase
blood lipids in rats fed a copper-deficient diet containing starch. In
contrast, the combination of high-fat diet with fructose increased
blood triglycerides and fructose with copper deficiency resulted in a
significant increases in blood cholesterol. CONCLUSIONS:
Hyperlipidemia of copper deficiency in rats is dependent on
synergistic effects between dietary fructose and copper deficiency and
fructose and amount of dietary fat. Hyperlipidemia does not develop if
starch is the main source of dietary carbohydrate in a
copper-deficient diet even if a high-fat diet is fed.

Still not the study referenced, below, I don't think but interesting.
Actually, there's a lot of intriguing stuff from this group.

The effect of time of introduction of a high-fructose, low-copper diet
on copper deficiency in male rats.
Lewis CG, Fields M, Beal T.
USDA, ARS, BHNRC, Beltsville, MD 20705.
The purpose of the present study was to compare the time of
introduction of the high-fructose low-copper diet on the expression of
copper (Cu) deficiency. Weanling male rats were randomly assigned to
either a diet containing 62.7% fructose or starch, and 6.0 (F+Cu) or
0.6 (S-Cu) microgram Cu/g diet, respectively, for either 1, 2, or 3 wk
before being transferred to a diet containing fructose and inadequate
in copper (F-Cu). At week 10, body weight and relative heart size of
rats initially consuming the F + Cu diet was inversely related to the
week placed on the F-Cu diet, but not for those initially consuming
S-Cu. Hematocrit, hepatic Cu concentration and RBC superoxide
dismutase activity were significantly lower in rats initially
consuming S-Cu when compared to those fed F + Cu. Mortality was
greatest in rats switched to the F-Cu diet at weeks 1 and 2 when
compared to those switched at week 3 regardless of the type of diet
initially consumed. Plasma cholesterol, triacylglycerols, and blood
urea nitrogen concentrations were not significantly altered by the
type of diet initially consumed or by the time of introduction of the
F-Cu diet. It was concluded that changing rats to a F-Cu diet at 1, 2,
or 3 wk after weaning did not significantly improve some of the
characteristic signs associated with Cu deficiency, but the later that
the F-Cu diet was introduced after weaning the greater the chances for
survival.
