High Fructose Corn Syrup Causes Bigger Weight Gain In Rats 542

krou writes "In an experiment conducted by a Princeton University team, 'Rats with access to high-fructose corn syrup gained significantly more weight than those with access to table sugar, even when their overall caloric intake was the same.' Long-term consumption also 'led to abnormal increases in body fat, especially in the abdomen, and a rise in circulating blood fats called triglycerides.' Psychology professor Bart Hoebel commented that 'When rats are drinking high-fructose corn syrup at levels well below those in soda pop, they're becoming obese — every single one, across the board. Even when rats are fed a high-fat diet, you don't see this; they don't all gain extra weight.'"

    That is because HFC is absorbed by the body in the same way that beer and alcohol is. In the liver. HFC also suppresses the satiety (hunger) signal so people tend to eat more.

      All fructose is processed by the liver in the same way as alcohol. That includes fruit juice.

      All this changes in the presence of fiber. If you eat a piece of fresh fruit, the fiber in the fruit changes the way the fructose from the fruit is absorbed so it's not such a huge shock to the liver.

      The bottom line is that if you eat carbohydrates, you should make sure it's with plenty of fiber. In other words, eat pieces of fruit, vegetables, and whole grains, just as nutritionists have been telling us for years. On food labels, I look for a % USRDA of fiber greater than or equal to the % USRDA of carbohydates, or grams of fiber at least 1/10 the grams of carbohydrate. It makes you feel more full with less food and prevents the sugar rush and crash from your liver absorbing the carbs too quickly.

          Exactly true, and yet millions of (nutritionally) uneducated mothers and/or fathers insist that their children drink plenty of juice (most of which is probably only 10% real fruit juice to begin with), instead of soda... because it's "healthy".

          I won't go off on my usual rant about the terrible food pyramid we've been brainwashed with since the 60s ("eat a shitload of bread, but NO FATS!"), but the bigger problem I'm seeing every day is just an utter ignorance about what people put into their body, or an unwillingness to try something different.

          "It says LEAN Cuisine on the box! That means I'll lose weight by eating it."

          My dad taught me something when I was younger, probably without even meaning to... if you can't pronounce all the ingredients, you shouldn't eat it. Of course, as a kid, I ignored that advice and just ate whatever tasted good. My mother did her best, but she grew up in an Italian household, which means a lot of pasta and other starches. When she went back to work, the fridge was filled with microwaveable "food", that I could nuke whenever I thought I was hungry. Guess who was a fat kid who sucked at sports, couldn't keep up with friends when there was running, biking, climbing, or jumping was involved? Guess who grew up to be a fat adult who tried all the same shit (pills, "diet" meals, "magic" exercise apparatus, etc.) as many other fat people, with the same results... still fat.

          It took a combination of a rough period in my life, combined with pure dumb luck... I was really low and, rather than drown myself in booze, I decided that I'd had enough, and that it was time to work on me. I got an email from a major men's magazine, offering a 30-day free trial of a book (which I've shilled on /. before), the title of which appealed to desire to be more of a man than I saw in the mirror at the time. The price of the book was less than a night at the local watering hole, so I went for it. When it arrived, first I thumbed through it. There was a lot of *common sense* stuff in there that just hadn't occurred to me before. So, I went back and READ it. Many an a-ha moment. Then I went back again and applied it. Now, at the risk of sounding like a braggart, I'm one of the most fit guys in the office. People are constantly asking for, and then either disregarding or outright refuting my advice. The result is, they're still fat, and I'm still not.

          Bottom line is, there's no magic pill, there's no silver bullet, there's really no secret. Back in the caveman days, right up to a half century ago, you almost had to try to get fat. Now, the food manufacturers (think about that phrase for a moment) are pumping chemicals into their products to make them taste better, cheaper. When I was a kid, McDonald's was a once-in-a-while treat. Now it's considered by many to be a viable option for all three major meals. People get in their car and drive to the store a block away. Hell, I see parents put their kids in the van and drive TO THE END OF THE DRIVEWAY to wait for the bus. People would rather wait in their car for 20 minutes in the Dunkin' Donuts drive through than park, get out, and be in and out of the place in 2 minutes.

      HFCF is fructose and sucrose. Fructose [wikipedia.org] is absorbed by the small intestine. Sucrose (table sugar) is broken down in the stomach and small intestine into 1 glucose molecule and 1 fructose molecule, which are then both absorbed by the small intestine. So, either way you get fructose, big deal, right? That's the conventional wisdom.

      But lets look further. If you eat 1 tablespoon of HCFC 55 (equal in sweetness to 1 tablespoon sucrose), you get .55 tablespoons of fructose and .45 tablespoons of sucrose. That sucrose is turned into half fructose and half glucose before entering the bloodstream. So in reality you ate .775 tablespoons of fructose and .225 tablespoons of glucose. This is significantly more fructose than if you had eaten 1 tablespoon of sucrose. And if you're consuming sugar water (as in the study) or lots and lots of soda, you're consuming far more than a tablespoon.

      Of course your claim that it's "absorbed ... in the same way that beer and alcohol is. In the liver" isn't quite correct. They're all absorbed by the small intestine, but it's true they are metabolized by the liver, albeit in completely different ways. What's might be important about the liver, though, is that it's not regulated by insulin. While glucose can be metabolized by any of the bodies cells, insulin regulates blood glucose levels. Fructose is only processed by the liver and is indifferent to insulin levels. So (in a layman's, but more detailed explanation) when you eat that 1 tablespoon of table sugar, you get half a tablespoon of unregulated sugar and half regulated. Eat the HFCF55 and most of the sugar is unregulated.

      As an aside, honey is almost identical in composition to HFCF55, so if you meet any holistics bemoaning HFCF and championing honey, you can tell them to screw off.

        HFCS is created with an enzymatic process. The HFCS food companies buy is dirty. It's mostly fructose and glucose but it also contains the enzymes used to convert the corn starch. You can't remove it all, apparently. And the standards are based on very small serving sizes. When people are drinking 50-100g a day of it, this enzyme builds up in the human system and attaches to other starch and performs the same conversion process to sugar. Normally this process takes more energy but with the unnatural enzyme it doesn't, and therefore it causes more efficient breakdown of starch. These people also tend to have a bag of chips or fries with their 50-100g of corn syrup. This means all of that becomes sugar. Since the body can't use the sugar, insulin is released and reactions occur and "bada-bing" FAT.

      Sorry, but that blog seems to be a wee bit on the crackpot side of things. The body does not really care how the fructose is administered - when it arrives in the intestine, it is in solution anyway, so no difference whether it comes crystalline or as HFCS. The effect should be the same. The problems that are pointed at in that post are probably true, however. Fructose triggers a lower insulin response than glucose, so the hunger persists despite caloric intake. Also, fructose is metabolized mostly, if not only, in the liver, which causes stress on the organ.

      Usual table sugar - sucrose - is a disaccharide made from one molecule of fructose and one of glucose. The glucose part triggers the insulin production, which signals that you have taken in calories. So, if you use normal sugar instead of HFCS, your body knows that you got energy way faster. That seems to be the main obesity mechanism associated with HFCS.

          You are right on the mechanism. However, there is another step. There is a liver-only fructokinase, which has a way higher Km than the hepatic glucokinase - so basically all fructose in the bloodstream is pulled by GLUT2 into the liver and retained there by phosphorylation through the hepatic fructokinase. The glucose also enters the liver via GLUT2, but is phosphorylated way more slowly, so a significant amount is not retained hepatically by the phosphorylation reaction. The additional liver stress and the main metabolic difference results from the fact that the subsequent metabolizing of F6P in the liver is insulin independent.

          Hope that suffices for starters. For more details, I'd have to break out the literature... and I am stressing my own liver with a decent red wine way too much for that at the moment ;)

        RE: Gatorade Thirst Quencher , REF.# 026139934A

        Bertrand:

        Thank you for contacting us about the High Fructose Corn Syrup
        (glucose-fructose syrup) in Gatorade Thirst Quencher. The important
        thing to know is that our formula has not changed. Gatorade contains
        the same scientifically proven blend of three carbohydrates -
        glucose, sucrose and fructose - in specific ratios.

        The glucose and fructose in Gatorade are essential functional
        ingredients required for rapid fluid absorption (an important
        component of hydration) and effective energy delivery. High-fructose
        corn syrup is glucose and fructose, and the body handles these sugars
        in the same way it handles the glucose and fructose provided by
        fruit.

        By way of background, carbohydrate sources do not contain only one
        type of sugar. For instance, table sugar (sucrose) is actually about
        50% glucose and 50% fructose.

        In the US, the term "High Fructose Corn Syrup" applies to both HFCS
        55 which is used in virtually all soft drinks (55% fructose with the
        remainder primarily glucose), and HFCS 42 used in Gatorade (42%
        fructose and the remainder primarily glucose.) In formulating
        Gatorade we use the HFCS 42 together with sucrose to create a blend
        that is appropriately sweet to encourage drinking, contains glucose
        for immediate use by the body, and yet does not contain too much
        fructose which, in large quantities, can cause intestinal distress.

        For weight maintenance, nutritionists agree that a sugar is a sugar
        and that it doesn't matter what your sugar source is. It just
        matters how much you consume. Many experts agree that HFCS has been
        unfairly demonized as a culprit in the obesity epidemic with no
        credible body of scientific research to support this notion.

        The Gatorade formula is continually tested by research scientists
        around the globe and proven on the world's best playing fields. We
        conduct ongoing research through the Gatorade Sports Science
        Institute to explore ways in which we can continue to deliver the
        best products, with the most effective ingredients, to our consumers.

        We hope this information helps you to make a more informed decision,

    Does anybody know of research that compares this to regular corn syrup (i.e., that which has not been "treated" to convert some of the glucose into fructose to bring the sweetness to table-sugar levels)? I'm just curious if it's corn syrup in general or if there's something peculiar to HFCS.

    In any case, I think people need to realize that neither table sugar nor HFCS is "good"--they're both concentrations of sweetness far greater than those found anywhere in nature, and they are purely empty Calories. Avoid them both and eat whole foods as much as you can--and, of course, get some exercise. (If only you could put that into the US healthcare bill!)

    . . . that nature INTENDED you to drink.

    Coffee.

    Cane sugar is far more efficient to produce than corn sweetener but is primarily produced in tropical and subtropical regions outside of the United States . The agribusiness lobby in in the United States pays off politicians to restrict imports, driving up the price of sugar within the the U.S. to above that of corn syrup. Without import restrictions on sugar, all those products you buy which are sweetened with corn syrup would be sweetened with sugar instead. And cost less.

    You can blame the agribusiness lobby and the protectionist whores in the U.S. congress for this situation. It is a clear-cut case of government power expended to benefit he corrupt few at the expense of the many.

    That, from now on, posting that crap about 'Calories in vs. Calories out' is an offense punishable by death.

    I've got a list of medical studies that show *what* you eat has a dramatic affect on your body composition; even when the calories are the same.

    And yet - I still hear it....all the time....'Calories in vs. Calories out'.

  • ketosis

    http://en.wikipedia.org/wiki/Ketosis [wikipedia.org]

    yes, its sort of the atkins diet, or the caveman diet: its how our caveman ancestors spent pretty much their entire lives, its what our biochemistry is idealized for, pre-agricultural revolution

    all it means is you eat fat and protein, and no carbohydrates. the pounds melt right off

    it forces your body to manufacture ketones from fat, and use that to power the krebs cycle (where you get your energy from), and to go into gluconogenesis (sugar from proteins)

    eat ALL YOU WANT: eggs and bacon, butter on everything, fish, chicken, cheese, nuts. eat fistfuls of macadamia nuts all day. even hard liquor (no sugar). but absolutely NO sugar or carbs, no rice, no bread, no milk, nothing sweet or starchy at all, period

    you won't be hungry, but the monotony of the diet will leave you hating fat and protein, and just the thought of popcorn will turn you into a craven vampire

    so what you do is carb cycle: you give yourself a break, say on weekends, where you get to pig out on sweets. trust me: ketosis during the week will more than make up for your indulging on weekends. it will also take you out of danger from the vague stresses you are putting on your body (see negatives below)

    funny thing: i felt more lethargic, but slept with less quality, when eating carbs again. this diet, for whatever its worth, really makes you realize that high carb diets are not what homo sapiens is optimized for. our biochemistry has not yet caught up with our recent (evolutionarily speaking) agricultural revolution

    i also have tinnitus, and i noticed that without sugar, the ringing in my ears was lessened, then, when i ate sugar, it came roaring back. they also use the ketosis diet to control people prone to seizures, so high ketones and no sugar seems to have a neurological impact. i would be interested in a study showing if the kind of inflammation which is alzheimer's is due to high carb diets: that's wild ass speculation on my part. i did read of a woman who put her alzheimer's husband on a ketosis diet of palm oil, and his symptoms got better (google it). again: THIS IS WILD ASS CONJECTURE, but a potentially interesting line of thought, the connection between carbs and inflammation in various disease systems

    drink tons of coffee, it seems to help with hunger. but it has to be BLACK: no sugar, no milk. also drink a lot of pepsi max/ coke zero: the sweetener in those is actually a tiny protein. drink gallons of the stuff, it will fill your stomach

    important: get your vitamins. since you're not getting many veggies (low carb veggies like broccoli and lettuce is pretty much ok, but you're missing out on wonderful foods like blueberries with this diet), you need supplements

    negatives:

    ketosis makes your blood slightly acidic (its not ketoacidosis, that's far worse, like with anorexics, who don't eat at all), which means you will be leaching calcium and magnesium, and stressing your kidneys and weakening your bones (this is all happening on a minor basis, relax). take calcium citrate supplements. paradoxically, eating more calcium will help you avoid kidney stones (the most common kind of kidney stone is caused by oxalate, and calcium inhibits oxalate absorption from the intestines), and the citrate helps in ketosis for... some reason i forgot. potassium and magnesium citrate supplements are good to, i forgot exactly why

    your breath will stink: you're exhaling acetone through your lungs while in ketosis. but remember, chicks don't like fat guys, and your diet is not permanent, so just avoid breathing on chicks for awhile while on your diet

    if these negatives scare you, think about the diabetes and heart disease you are giving yourself with your carb addiction: far more dangerous than a temporary diet which will make you a healthy weight

    The data in the actual paper [mediafire.com] doesn't support the conclusion in the title of the Slashdot story.

Slowly and surely the unix crept up on the Nintendo user ...
