Crystallized Fructose?
 
I'm hearing a lot about Crystallized Fructose to be used as a sweetener, rather than sugar, artificial sweeteners. Does anyone know anything about it? I know high-fructose corn syrup is bad....but this is not the same.

All I've been able to find so far (except on the group) is this: http://www.starch.dk/isi/starch/fructose.htm

Quote:
Fructose, also levulose or fruit sugar, monosaccharide with the formula C6H12O6 that occurs with glucose in sweet fruits and fruit juices. It is formed along with glucose in the splitting of sucrose and is produced in the hydrolysis of various carbohydrates, but it is best prepared by treating inulin with dilute acid. Fructose is crystallized with difficulty; the crystals melt in the range from 102° to 104° C (216° to 219° F). It is laevorotatory; that is, solutions of fructose rotate the plane of polarized light to the left. Fructose is fermented by yeast to yield ethyl alcohol and carbon dioxide.

Fructose is generally refined from corn starch. It is claimed to be anywhere from 15 to 80% sweeter than sucrose, and tastes particularly sweet when cold or in solution. It is believed to be absorbed into the gastro-intestinal tract more slowly than glucose, and does not require insulin for entry into the liver. These features make it appealing to diabetics, but the advantages are somewhat offset by its higher tendency to be converted to fat rather than glycogen, thereby elevating blood triglyceride levels.

Hi Cindy,

Fructose has a much lower GI than glucose, but unless it is natural, ie still inside the fruit, ;) I'd give it a big miss.

Here is some information from Doreen you may find interesting:

But the fructose that gets added to food - even so-called "natural" food - and the white crystalline powder that's sold in bulk and natural foods stores is definitely not natural, and does not come from fruit. It's a highly refined monosaccharide sugar, made from corn syrup or corn starch. More recently, they've discovered a way to treat white table sugar (sucrose) chemically, so that it converts part of its glucose content to fructose. This type of sugar is very cheap to produce, that's why the food industry loves it; and because it's sweeter, they can use less of it. But it is everywhere -- soft drinks, "natural" juices and fruit drinks, baby food, desserts, candies .. you name it.

Fructose is readily absorbed into the cells to be used as fuel .. without requiring insulin to do so. Thus, there is no significant rise in blood sugar (the fructose is so rapidly absorbed, it doesn't stay in the blood long enough) nor insulin levels. This is what makes fructose have such a low "glycemic" value. However, your body will use the fructose for fuel first, therefore your fat-burning will be put on hold. It can and will halt ketosis.

But that's the good news... ..

The bad news is -- the fact that fructose doesn't require insulin to enter the cell actually increases the likelihood of developing insulin resistance. Many researchers are blaming the alarming increase of type 2 diabetes in KIDS to the fact that fructose, in the form of high-fructose corn syrup, is THE most commonly added sweetener in processed foods, especially the "healthy" fruit drinks.

As well, fructose is now known to increase blood lipids, in particular triglycerides. And it has been linked for years to increased risk of heart disease .... Glucose sugar binds with proteins in the body, and in the process it damages the DNA of the protein. Research has shown the link of this sugar-damage (called glycation) to the plaque buildup and hardening of artery walls. Fructose can bind to proteins 10 to 15 times more readily than glucose.

In Protein Power Lifeplan, the Eades discuss the dangers of fructose pp 159 - 162. As well, you might want to read this eye-opening article, written by Jack Challan, the Nutrition Reporter. I guarantee you will think twice before allowing your family to consume anything with fructose in it. ... http://www.nutritionreporter.com/fructose_dangers.html

Read and Learn.

Thanks rose! I knew someone would answer me!

I can't believe I missed Doreen's post...I did a search prior to posting.

I've heard about this on a low-glycemic eating group. I'm still not clear on just what their WOE is, but the chrystalized fructose was mentioned as being used by most members.

I'll check out the articles you provided and see if I can figure them out a little better!

Thanks again

PS....I have a post about apples....can you help there too? :lol:
