How Fructose In the Diet Contributes To Obesity (sciencedaily.com) 154

An anonymous reader quotes a report from ScienceDaily: Eating fructose appears to alter cells in the digestive tract in a way that enables it to take in more nutrients, according to a preclinical study from investigators at Weill Cornell Medicine and NewYork-Presbyterian. These changes could help to explain the well-known link between rising fructose consumption around the world and increased rates of obesity and certain cancers. The research, published August 18 in Nature, focused on the effect of a high-fructose diet on villi, the thin, hairlike structures that line the inside of the small intestine. Villi expand the surface area of the gut and help the body to absorb nutrients, including dietary fats, from food as it passes through the digestive tract. The study found that mice that were fed diets that included fructose had villi that were 25 percent to 40 percent longer than those of mice that were not fed fructose. Additionally, the increase in villus length was associated with increased nutrient absorption, weight gain and fat accumulation in the animals.

After observing that the villi were longer, the team wanted to determine whether those villi were functioning differently. So they put mice into three groups: a normal low-fat diet, a high-fat diet, and a high-fat diet with added fructose. Not only did the mice in the third group develop longer villi, but they became more obese than the mice receiving the high-fat diet without fructose. The researchers took a closer look at the changes in metabolism and found that a specific metabolite of fructose, called fructose-1-phosphate, was accumulating at high levels. This metabolite interacted with a glucose-metabolizing enzyme called pyruvate kinase, to alter cell metabolism and promote villus survival and elongation. When pyruvate kinase or the enzyme that makes fructose-1-phospate were removed, fructose had no effect on villus length. Previous animal studies have suggested that this metabolite of fructose also aids in tumor growth.
From an evolutionary standpoint, the findings make sense. "In mammals, especially hibernating mammals in temperate climates, you have fructose being very available in the fall months when the fruit is ripe," said one of the researchers. "Eating a lot of fructose may help these animals to absorb and convert more nutrients to fat, which they need to get through the winter."

Humans, on the other hand, did not evolve to eat the amount of fructose they consume now.

    I found this 90 min lecture from 2009, Sugar The Bitter Truth [youtube.com], by Robert H. Lustig, MD, UCSF Professor of Pediatrics in the Division of Endocrinology very interesting:

    [He] 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.

    The video explains in detail how fructose is metabolized by (and only in) the liver in a fashion very similar to alcohol -- noting that while alcohol consumption is self-limiting, fructose consumption is not and discusses the problems that can cause, like "fatty liver" (even in children).

              HFCS has a very bad rap and has for a long time, and this study adds to it. But is there any good reason why people talk about HFCS in particular, instead of fructose in general? Is the fructose / glucose dichotomy all there is to know about bad vs. less-bad sugars? (There are a lot of related concepts like glycemic index that people will happily go off on, but what is sound?)

                HFCS and granulated sugar are equally bad. The most common HFCS used is chemically identical after the body breaks it down as sugar. In sugar the fructose and glucose are bonded and broken down in the gut. In HFCS they are already separate. In both cases they are absorbed the same way.

                I think the major issue is in America HFCS is in fucking everything! Like everything is unbearably sweet. Sure, a cola in Europe and a cola in the USA both contain 11% sugar or HFCS in equally nutritionally crap amounts, but move beyond the intentionally sweet and you find big differences. HFCS added to juice, guys, seriously juice already has sugar in it. HFCS added to tomato sauce, HFCS added to a damn loaf of bread.

                Travelling to America it takes some adjusting to the fact that everything just tastes sweet, often sickeningly so.

              You're doing the math wrong. HCFS in its most common form is 55% fructose, versus sucrose, which has 50%. So for a given amount of HFCS, you have 10% more fructose than in that same amount of glucose (because 55 / 50 = 1.1).

              That's not a small difference. It's not a huge difference, but it's not a small difference, either. :-)

And considering that a mixture of glucose and fructose is sweeter tha surcose [wikipedia.org] and that of the two, glucose and fructose, fructose is much sweeter, it takes quite a bit less of HFCS to reach the same sweetness as surcose.

                  That still kind of misses the point. The difference in the amount of sugar you get between a 50/50 mix and a 45/55 mix or whatever isn't a lot, but the difference in the amount of fructose is significant. And if fructose causes biological changes that encourage weight gain not only from the sugar, but also from non-sugar energy sources, then even though you're consuming less sugar, you're still potentially absorbing more calories.

                  Also, the other big difference between glucose and fructose that folks often overlook is the fact that glucose triggers an insulin response, whereas fructose doesn't. And insulin is at least in part responsible for making you feel full. So when glucose is replaced with fructose, you consume more than you otherwise would. So even if there is less sugar per serving with a higher fructose-glucose ratio, you're likely to consume more servings.

                  Although all sugars in too great a quantity are bad, HFCS is considerably worse than glucose, for the reasons previously mentioned.

                  That said, I agree that we consume too much sugar (in all forms). One big reason for that is because of the "low fat" hoax, where the sugar industry managed to convince policymakers that fat was the enemy. Unfortunately, fat also makes you feel full, which made people eat more. And when you remove fat from foods, you have to replace it with something, or else the food tastes bad, and that fat was often replaced with sugar or HFCS.

        Corn syrup added to everything is an epidemic in this country.

        Ironically, unmodified corn syrup is fine. It's basically pure glucose, which causes you to feel satiated because it triggers an insulin response, and doesn't cause this secondary impact on your digestive system.

        What's bad is high-fructose corn syrup, where they have modified it to convert some of that glucose into fructose, both because you have the same amount of sugar content with half the insulin response and because of what they're talking about here.

      That's correct. It's also why fructose does not need insulin to be processed and thus doesn't have a contribution towards diabetes. However, as pretty much indicated everywhere, for what upside fructose has over sucrose in monosaccharides you should absolutely not make consuming either a regular thing. For the very reason you've just stated, regular fructose consumption will pummel your liver like none other because it's not self-limiting. And for obvious reasons over consumption of sucrose will shred your pancreas.

      It's just insane how much we've added both of these things to everything we eat when it's very clear that we didn't evolve to consume this stuff in large amounts. Non-Alcohol Fatty Liver Disease (NAFLD) is no joke to have and in the US the incidence of it has tripled [nih.gov]. It's just unreal how prevalent NAFLD has become in recent years.

    • The prevailing view is that obesity causes insulin resistance rather than insulin resistance causing obesity. That view has been challenged though and the full relationship isn't clear. IMO this new study demonstrates a much stronger potential correlation between fructose and obesity than the liver metabolism correlative effect that Lustwig discussed.

        We eat desert at the end of the meal because long, long ago we found that when you were full, you could still eat something sweet. It was a way to cram in more calories so we could go longer without eating, work longer, shiver more, etc. Think northern European middle-ages.

        Satiety comes from the flow of sugars (coming from the breakdown of complex structures, one hopes) flowing from your stomach. In other words, once initial processing starts in the stomach, you start to feel full.

        But sugar on the tongue overrides that. Or rather the sensation of sweet on the tongue overrides it, so artificial sweeteners still get you fat because you eat more other things because it messes with your satiety response.

        Because of this, adding sugar to everything makes us keep eating. Japanese food, without sugar, is normal food. Modern Western food is food designed to keep you eating by overriding the satiety you would normally feel. Which is nuts.

So year after year it costs U.S. taxpayers $4 billion to keep the price of sugar higher than it should be.

            Leptin resistance [nih.gov] does not make you over eat or “misdigest” anything. It’s simply limited to appetite regulation and some increased resistance actually leads to decreased appetite. It’s true that it’s a statistically likely component of obesity because there are cases where it can simultaneously cause increased appetite and decreased metabolism.

"Fructose is nearly ubiquitous in modern diets, whether it comes from high-fructose corn syrup, table sugar, or from natural foods like fruit," he said. "Fructose itself is not harmful.

    But first of all: Mice?
    Mice are not humans!
    Might as well test it on horses that were fed mostly grasses like oats.
    Could you at least try monkeys? Like those that eat fruit, for example.

    Next: Again, they are building their research on western gut microbiomes. Which are already severely ruined. Like studying how humans poop by looking at Goatse. Actually, even worse.

    The problems with fructose all stem from a gut, so ruined, the normal process of digestion is not even possible anymore, because the organisms are gone.

    Essentially, those things that "cause an upset stomach" because they are "hard to digest" are actually what keep your gut healthy. It's not those foods that are the problem. It's the crap you ate that ruined your gut for actual food so badly that you feel stuck.

    If you'd compare human food to Opium, then what we eat nowadays, would be mostly Krokodil and Fentanyl.

      The War on Fats is deeply entrenched in America, and dietetics programs are not swiftly incorporating new research against it. It's amazing that we go on and on about our health care and insurance spending in this country and how it's out of control versus other countries, but we don't do much at all about our food sources, which are quite different from those other countries. We complain about our outputs and aren't making the appropriate changes to our inputs. You are what you eat.

      Paywalled but great article on the subject: https://www.nytimes.com/2016/09/13/well/eat/how-the-sugar-industry-shifted-blame-to-fat.html [nytimes.com]. Seriously - there are few things in the last century of American history where corrupted government officials have caused more significant and lasting damage. Hell, due to the disease this has caused and the years of lives lost, the economic damage is likely staggering as well.

    Humans, on the other hand, did not evolve to eat the vast quantities of ANYTHING they consume now.*

    • To be fair to the conversation, some facts are relevant to show how bad it is in US society.

      The CDC/FDA & Medicare divisions know because they pay a lot of the bills & collect & "follow the data":

      About 90 million (mostly a supermajority or more of 120 m seniors) Have:
      a. Chronic GI problems
      b. Obesity
      c. 5+ prescription medications (let alone OTC meds) with many being caused directly or i

    • ... the west? We didn't evolve to eat unenriched/fortified rice and flour either. Malnutrition is a worldwide problem.

  • My non-obvious takeaway from this research is that when people are on survival rations, e.g. right now today in Haiti, it makes sense to supplement those rations with some amount of Fructose to increase the net impact of each calorie. You'd want to understand how quickly this effect occurs before investing a lot of effort in it. If it takes months to kick in then the immediate effects of the disaster would likely be over. This information would also be informative to the evolutionary bounty before winter
