Fructose Tied to Obesity as Study Shows It Doesn’t Cut Appetite
Source: Bloomberg.com
Fructose, a sweetener found on many food labels, may contribute to weight gain and obesity because it has minimal effect on brain regions that control appetite, a study by Yale University researchers found.
The research, published yesterday in the Journal of the American Medical Association, is the first to compare the human brains response to both fructose and glucose, two types of simple sugars used separately and together to sweeten food.
Researchers have long suspected that increased consumption of food flavored with fructose, a substance sweeter to the taste than glucose, may contribute to the U.S. obesity epidemic. The latest study used brain imaging to measure activity after the sweeteners were consumed. It found that only glucose had the ability to reduce blood flow in areas of the brain that regulate appetite, stopping people from wanting to eat more.
The data surely suggest that its probably not in your best interest to have high fructose-containing drinks because theyre not going to cause you to be full, and youll tend to consume more calories, said Robert Sherwin, a professor of medicine at Yale University School of Medicine in New Haven, Connecticut, in a telephone interview.

(11,843 posts)The study says that high fructose is questionable, so there goes drinking fruit juices... The amount of fear and woo on the topic of sweeteners is incredible. The bib problem is not what sweeteners, it's how much is consumed.
i.e. "High Fructose Corn Syrup" is the cheap sweetening food additive that is made from corn and is liberally used by food manufacturers. Worldwide epidemic of obesity has occurred since the advent of HFCS by Japanese researchers.
It is way cheaper and sweeter than real sugar (sucrose) and profits drive its use.

(11,843 posts)succrose. There is essentially no difference between the two. The problem is how much sugar (from any source) is added to foods. They do the same with salt. If all the food companies would just back off all the added sugar and salt, we would be healthier and not notice the difference.
Fear mongering about HFCS serves no purpose other than to label oneself as a woo-woo conspiracy theorist.

HFCS-90 is 90% Fructose and 10% Glucose.

Once again, the source of sugar means jack. It's the amount of sugar consumed that is the problem.
We are so overdosed on sugar that we have tolerance, it takes a lot of sugar for the average American to say something is sweet. People who aren't used to American processed foods think they are overly sweet. Food producers could wean us off the sugar and salt if they wanted and no one would even notice, until they needed to buy smaller clothes.
If you want to be a "follow the money" conspiracy theorist, you don't have to look any further than the Corn Lobby. The reason corn syrup it is cheap is the subsidies given to the big corn producers.

Years ago. Not "a lot of years," but years.
It's one argument against apple juice for infants, as well. Rots their teeth, makes the tykes fat.

(17,276 posts)And this doesn't only pertain to high fructose corn syrup. Ordinary table sugar is half fructose, half glucose.
Any time you eat sweets, be aware that your appetite won't turn off normally, and you will have to make a decision to stop eating anyway.
but this finding is hardly new.
Excessive fructose leads to a whole host of metabolic problems-- diabetes, heart disease, liver problems

(26,549 posts)Our "hungry" sensor is based on glucose. Fructose doesn't trigger it, but fructose also doesn't suppress it.

(26,549 posts)HFCS in sodas is about 50% fructose, 50% glucose. Sucrose (aka sugar) is 50% fructose, 50% glucose.
Yeah, switching from HFCS to sugar is gonna make a huge difference.
Better yet, let's tell people to avoid HFCS and instead drink 100% organic, all-natural fruit juice. Which is almost all fructose and very little glucose.
I'm really tired of people searching for a magic food that will fix the "obesity epidemic" either by eating it or by avoiding it. It's really not that complicated - we eat too many calories and get too little exercise. But fixing those takes more work than magic food, so we keep getting fatter while we desperately search for magic food.

(4,553 posts)I think I recall that HFCS consists purely of monosaccharides. I'm thinking the control they would need to run is a drink sweetened with difructose, thereby allowing the liver to break that down.
jeff47
(26,549 posts)It breaks into fructose and glucose very, very, very quickly and then we absorb the fructose and glucose in the small intestine. So it would be extremely surprising for there to be a difference.
And again, HFCS is roughly 1/2 fructose and 1/2 glucose. Difructose isn't an analog for HFCS. Though it would be pretty easy to generate a 50% fructose 50% glucose solution from something other than corn syrup to conduct your experiment.

(26,549 posts)Your brain cells can only eat glucose. The rest of your body's cells can eat a wider variety of food. But it's because of the brain food requirement that our "hungry sensor" is based on our glucose level.
So I really don't think one can call sugar "poison", since it's a key chemical for keeping you alive.

(26,549 posts)It's taking in too many calories from all sources, not just sugar. Eat tons of beef and you'll still get fat despite the beef having very little sugar.
There are no magic "don't eat this and you'll be thin" foods. It's all calories in versus calories burned. Though you'll be far healthier adding to that second part instead of only restricting the first.

(26,549 posts)Apple juice is apple-flavored sugar water. All-natural, but it's lots of empty calories that won't satiate your hunger.
An apple throws in a bunch of fiber with the apple-flavored sugar water, filling you up much more and thus reducing the total calories you'll eat.
