"Fructose suspected as latest fat factor"

Even if one thinks the analysis simplistic, this story
is getting wide publicity and will produce benefits I
think; refined carbs in general are getting the bad rap
they deserve.

This is absolutely ridiculous... Listen, HFCS probably
isn't the best thing in the world, but it doesn't make
people obese... People make themselves obese when they
hoarde the stuff and pump themselves full of it. It is okay
if eaten in moderation, it will not make you fat on
occasion. Eating and drinking high levels of this stuff,
that is what makes you fat.

Assume that you had a food which did the following :

1) Had no satiation responce
2) Massively increased appetite
3) Promoted fat storage and decreased metabolism
4) Was fully digested in less than 30 minutes

compared to a food which :

5) Had an extreme satiation effect
6) Massively dereased appetite
7) Increased metabolism
8) Was fully digested in more than eight hours

It should be obvious that there is a significant in those
two foods in regards to tendancy for weight gain. Fructose
is of the first type.

I don't know how similar HFCS is to cane/beet sugar but I do
know that if you eat too much of one thing you are going to
gain weight. Also, its probably not a bad idea to have a
diet soda once in a while instead of a regular one.

Fructose is quite slowly absorbed into the bloodstream. This

It has the same calories as many other foods and will only
put on weight if excess is eaten wrt calorie allocation.

To clearify I would not want to argue that you can simply
claim "fructose made me fat" with a complete lack of
responsibility. While I do think manufacturers need to
address that sugar can act as addictive drug, common sense
would tell you that you have a problem long before you are
100 lbs overweight. Also, eating an apple in the morning
isn't going to give you fructose-related obesity, most
natural sources of fructose even the dense ones like sweet
fruit, are no where near as dense compared to the
artificially sweetened ones.

The problem with artificaly fructose laden foods is that
they they typically have no inherent satiety responce (low
fat and low bulk volume), they can be eaten *very* quickly,
and encourage appetite. Try eating something very sweet and
see how much of it you can eat until you physically feel
full, considering that it takes about 20 minutes for your
brain to realize this has happened, the problem is obvious
with highly refined sugared foods. Which is why diabetis and
related disorders are increasing steadily, with more than
2000+ cases being diagnosed every day in the US alone.

Yes of course the amount of raw calories is an influences,
but you will see significant differences in fat and lean
muscle gains on isocaloric diets, plus differences in mood,
mental ability, etc. .

How?

Blood does not contain fructose. It does contain glucose.
HFCS is converted into glycogen and some is stored in muscle
and some is stored in the liver. That which is stored in
muscle becomes fat

healthatoz.comglycogen sOpen ↗
torage_diseases.html Most of the body's cells rely on
glucose as an energy source. Glucose levels in the blood
are very stringently controlled within a range or 70-100
mg/dL, primarily by hormones such as insulin and glucagon.
Immediately after a meal, blood glucose levels rise and
exceed the body's immediate energy requirements. In a
process analogous to putting money in the bank, the body
bundles up the extra glucose and stores it as glycogen in
the liver and muscles. Later, as the blood glucose levels
begin to dip, the body makes a withdrawal from its
glycogen savings.

waltonfeed.comfructose.htmlOpen ↗ Your body can't use
fructose without converting it into glucose in the liver.
Actually, most of the time, however, unless your body needs
to immediately increase it's blood-sugar level, the liver
changes fructose into glycogen first. We have already
mentioned glycogen which is the body's short term energy
supply. A typical adult will have as much as 3/4 pound of
glycogen in their various tissues at one time, mostly stored
in the liver and muscles. As the glucose level in the blood
begins to drop, the liver can rapidly convert this stored
glycogen into glucose.

protraineronline.comfruit.cfmOpen ↗ Our
bodies can only absorb monosaccharides (glucose, galactose,
or fructose), the single units of sugars and starches. Once
absorbed through the small intestines into the portal vein,
and then circulated into the bloodstream through the liver
as blood glucose, our bodies can put glucose to work in
three ways:

It can burn the glucose immediately for energy if blood
glucose levels are not at a stable level of 20 grams blood
borne glucose circulating per hour.

If it is not needed for energy immediately, then it is
converted into glycogen in the liver or muscles. The liver
has the capacity to store 100 grams of glycogen. The muscles
have the capacity to store between 250-400 grams of
glycogen, depending on muscle mass and physical condition.
Liver glycogen supplies energy for the entire body. Muscle
glycogen only supplies energy to muscles.

If the body has an excess of glucose, and all of the
glycogen stores are full, the surplus glucose is converted
to fat by the liver and stored as adipose tissue (bodyfat)
around the body. If needed, fatty acids can be burned as
fuel (BUT the fat cannot be converted back to glucose).

Now that we have outlined how our bodies use glucose, we
will discuss why fruit (fructose or fruit sugar) is
detrimental in an attempt to maximize fat loss. Since
muscles have the specific purpose of contraction, they have
a limited number of enzymes for glycogen synthesis. Muscle
only has the necessary enzymes to convert glucose (and
nothing else) into glycogen. The liver, however, is able to
make glycogen from fructose, lactate, glycerol, alanine, and
other three-carbon metabolites. Muscle glycogen, which is
similar in structure to starch, is an amylopectin (branched
chained polymer containing hundreds of glucose units).
Unlike muscles, which can only supply energy to themselves
through the stored 250-400 grams of glycogen, the liver is
responsible for supplying energy to the entire body.

If you have fruit, fruit juice, or any of its derivatives,
the following conditions occur:

Referring to the three ways the body uses glucose, assuming
that blood glucose levels are adequate, the glucose will
then be stored as glycogen. Muscle does not have the
necessary enzymes to synthesize fructose into glycogen;
therefore the liver converts this fructose into liver
glycogen. It would only take three, 8-ounce glasses of
orange juice to fully replenish liver glycogen stores. Since
the liver is responsible for supplying energy to the entire
body, once its stores are full, a rate limiting enzyme in
glucose metabolism which is responsible for signaling the
body to store glucose as glycogen or convert it to fat
(phosphofructokinase), signals the body that all stores are
full. If the glycogen stores are signaled as full, then the
third way our body uses excess glucose is to convert it to
fatty acids and store as adipose tissue. In essence, fruit
sugar is easily converted to fat.

Many may be asking why then is fruit low on the glycemic
index? If it does not cause a sudden release of insulin,
then how could it ever be a poor food choice? Once the
fructose (fruit sugar) enters the liver and liver glycogen
is already full, then it can not be used by the muscles for
glycogen or energy production. It is converted to fat and
released back into the bloodstream to be stored as adipose
tissue. The low glycemic response is based on the fact that
fructose leaves the liver as fat, and fat does not raise
insulin levels.

This is the biochemistry behind the recommendations to limit
fruit in your diet. As mentioned, fruit is a very nutritious
food full of vitamins, minerals, fiber, and low in calories
and fat. If your goal is to exclusively to minimize bodyfat,
then it is advisable that you consume more complex
carbohydrates, which will go to replenishing muscle glycogen
stores rather than fruit, which will only replenish liver
glycogen stores, and is useless in muscle glycogen
replenishment.

Very nice, but if you are eating eucalorically, it's
academic. Of course all sorts of problems occur when you eat
too much energy. Various fats an other nutrients become
problematic. The beauty of fructose is its slow absorption
into the blood and hence its ability to be used for energy
in the longer term than glucose. Glucose for fright and
flight, and fructose for trekking back to the cave over the
next several hours.
