We're wallowing in sugar and Fructose, and Endocrinologists tell us why that is bad

Robert H. Lustig, MD, UCSF Professor of Pediatrics in the Division of Endocrinology, explores the damage caused by sugary foods. He argues that fructose (too much) and fiber (not enough) appear to be cornerstones of the obesity epidemic through their effects on insulin.
Some of the takeaways for me are that Fructose is bad. Fructose is digested mostly in the liver, and results in around 30% of the food energy from fructose goes right into fat stores from the liver. It also results in increased uric acid output, which increases blood pressure. Eating fructose also suppresses Ghrelin, which causes you to be hungry.
Sucrose (table sugar, cane sugar, cane juice), are half fructose.
The Wiki on Fructose and sucrose are interesting reading, too:
http://en.wikipedia.org/wiki/Fructose
The Entries for "Liver Disease', 'Digestive Problems", "Metabolic syndromes", and "Gout" are food for thought. What it does to your liver sounds nasty.
http://en.wikipedia.org/wiki/Sucrose
Sucrose is half fructose!
This article from The Journal of Clinical Endocrinology & Metabolism says some of the same things:
"Dietary Fructose Reduces Circulating Insulin and Leptin, Attenuates Postprandial Suppression of Ghrelin, and Increases Triglycerides in Women"
http://jcem.endojournals.org/cgi/content/full/jcem;89/6/2963
It appears that Fructose impairs our memory as well!
"How Fructose Impairs the Memory"

Even though normal cells in your body can not metabolize fructose directly, it appears that cancer cells can metabolize fructose to speed cancer growth!

After learning more about Fructose, I'm attempting to cut it out of my diet.
How did America become convinced that eating fat was bad, and eating sugar was good?

One of my friends said that she cooks with Brown Rice Syrup. It appears to have no fructose, consisting of the sugar of life, glucose, according to the Wiki entries
http://en.wikipedia.org/wiki/Brown_rice_syrup
http://en.wikipedia.org/wiki/Maltotriose
Maltose in beer also seems to be the safe sugar, Glucose
http://en.wikipedia.org/wiki/Maltose
The Wiki on Beer is interesting, too:
"Several diet books quote beer as having an undesirably high glycemic index of 110, the same as maltose; however, the maltose in beer undergoes metabolism by yeast during fermentation so that beer consists mostly of water, hop oils and only trace amounts of sugars, including maltose."

If you're also curious about what sweeteners might be safe, it appears that Glucose, the sugar of life, is safe. Every cell in your body can metabolize it.
The commercial sweetener, dextrose, is glucose. So is plain 'corn syrup' (but not high fructose corn syrup):
http://en.wikipedia.org/wiki/Corn_syrup
The Wikipedia entry for glucose is interesting:
http://en.wikipedia.org/wiki/Glucose
Under 'Function':
"Scientists can speculate on the reasons why glucose, and not another monosaccharide such as fructose (Fru), is so widely used in organisms. One reason might be that glucose has a lower tendency, relative to other hexose sugars, to react non-specifically with the amino groups of proteins. This reaction (glycation) reduces or destroys the function of many enzymes. The low rate of glycation is due to glucose's preference for the less reactive cyclic isomer."
That paragraph seems to be saying that glucose is much less likely to mess with proteins and enzymes in your body than fructose is.
