Drinking one glass or more of 100% fruit juice each day is associated with weight gain in children and adults, according to a new analysis of 42 previous studies.

The research, published Tuesday in JAMA Pediatrics, found a positive association between drinking 100% fruit juice and BMI — a calculation that takes into account weight and height — among kids. It also found an association between daily consumption of 100% fruit juice with weight gain among adults.

100% fruit juice was defined as fruit juices with no added sugar.

    Carbs are carbs, sugar is sugar, high glycemic sugars need somewhere to go quickly

    I have a relative, a PhD no less (albeit in English), who “only eat natural organic GMO-free” and will absolutely not accept that fruits are sweet because of sugar and count against you like any other sugar

      Well, while it is a type of sugar that makes fruits sweet, it in fact does get processed differently in your body. Fructose, among other things, can’t be stored in muscles. Your body also doesn’t need to provide Insulin to process it.

      When comparing something sweetened with Fructose and something sweetened with Saccharose, the sweet from Fructose has less negative health impacts.

      Unless I misunderstood what you mean with “count against you” (I am not a native English speaker).

          No it is not false. You just misunderstood what I wrote or what is written in the paper.

          I explain to you: We do not need to produce Insulin to metabolise Fructose. Because Fructose can enter cells without it. The Insulin produced in response to a high dose of intravenously administered Fructose (like in the 1980 study you posted) never gets active in the cells, so to speak.

          The potential negative health effects of that are discussed in several articles, more recent ones at well. But this effect is only relevant for the high direct doses of these studies design, which also often combine it with other sugars. It’s not relevant for the consumption of fruits and vegetables.

        the sweet from Fructose has less negative health impacts.

        I wouldn’t call fatty liver not a negative health impact. In particular Type II diabetes is reversible, a sufficiently fucked-up liver is not.

          That’s why I did not wrote “a fat liver is not a negative health impact”.

          I wrote Fructose has less negative health impacts. This means when you count health impacts there are less (= a smaller number) for Fructose.

            (= a smaller number)

            Are you seriously suggesting “health impact” is a thing measured by “quantity of diagnoses that apply”. I have 1000 ingrown hairs, another person has one fatty liver. Which of us is more fucked?

              Health impacts.

              I feel like you try to derail the conversation and move goal posts to “be right”.

              Fruits and vegetables contain Fructose, Fructose has a smaller number of negative health impacts than Saccharose and Fructose is metabolized differently in our body than other sugars.

              The intravenous administration or other consumption of very high doses of Fructose, often in obese and/or diabetic patients in studies, has been identified as a potential risk factor for fatty liver.

              That doesn’t mean eating fruits and vegetables increases the risks for a fatty liver. It also doesn’t mean Fructose and Saccharose are the same.

                Saccharose is half fructose, half glucose. Eat enough of it and the impact on the liver is just as bad as that of fructose which is definitely worse than overeating on more or less pure glucose in the form of, among other things, starch. The body overall is way better at dealing with glucose as pretty much everything that needs energy can use it directly, while fructose first needs to be processed in the liver, which has a much more limited capacity. Ingesting fructose (also in the form of saccarose) makes sure that the liver’s glycogen stores are stock-full, which means that weight loss is impossible as that storage gets used up before adipose tissue gets involved.

                The intravenous administration or other consumption of very high doses of Fructose, often in obese and/or diabetic patients in studies, has been identified as a potential risk factor for fatty liver.

                Dietary consumption of high-fructose corn syrup alone is a risk factor for fatty liver, get out of here with “intravenous” and “very high dose” and “in obese patients”. Non-alcoholic fatty liver is a fucking epidemic.

        Sure, if you’re otherwise healthy, but the point is don’t drink a glass of sugar water thinking it’s healthy because fruits or vitamins or some bullshit, because it’s not, and you probably don’t need the extra calories.

        Unless you do, and then you probably already know your shit anyways.

        I am interested how someone is supposed to live a healthy life without fruits and vegetables. Sure, you do spare the calories that stem from the Fructose, I guess.

          They don’t. Keto is the most unhealthy of all alternative diets partly for that reason.

          Your brain needs carbs. Without carbs, your brain rots. And your liver gets damaged.

          That being said, simple carbs like table sugar, HCFS, etc. are to be avoided because they spike your blood sugar and cause inflammation which ages your body. The sugars you get from fruits and veggies are not table sugar, they’re fructose and other kinds, and they’re mixed in with the fiber of the fruit so you don’t get the blood sugar spike when you eat them.

          Eating below the number of calories you burn will make you lose weight regardless of where those calories are from.

          People don’t get that because they don’t bother to do the research, that’s all.

            Yeah, I know… I’ve given up at that front with some of the comments here… It’s unfortunate, but I feel the whole issue with many topics in nutrition is that it’s unreasonable to expect for most people to read up on organic chemistry and metabolism lol And even if you have some understanding, much is still far from understood well.

            So most people end up with a superficial (mis)understanding. And Fruits, Corn Syrup, fresh juice, “100 % juice but actually it’s concentrate” get all tossed together in one bag because omg Fructose.

            I’ve certainly seen an increase in people on- and offline claiming fruits are essentially death cookies. Sometimes even expanding that to peas etc. because they realised Fructose is in them.

              My guy, if you are eating 2000-3000 calories a day, you’re not actually going to be in a deficit, especially in a sedentary line of work like IT. Calories ARE the reason you gained weight, and you likely overestimated the number of calories you were consuming when you were eating a high-protein diet.

              Calories are calories. The problem with high-carb foods is the blood sugar spikes they can cause if they are simple carbs and not whole ones like what you’re supposed to be eating. You say you were eating Ramen packs; those things are filled with MSG and other chemicals that trick you into eating more. The blood sugar spikes do that to you, too. It’s partly why simple carbs are so dangerous.

              Had you eaten whole grains like oatmeal and brown rice, which would have been cheaper anyway, that would not have happened to you. You’re supposed to eat whole carbs with the fiber and germ still in it, like whole wheat, rye or sourdough bread; brown rice; whole wheat or certain gluten-free alternate noodles that aren’t wholly processed, sweet potatoes, stuff like that.

              The nuance here doesn’t actually favor your position. I lost 30 pounds when I switched to a Mediterranean style diet, which requires lots of carbs, only in the whole grain variety, and yet I eat cheaper and healthier than resorting to Ramen packs. 🤦

              Good grief. It’s no wonder you gained weight and wrongly attributed the target. Didn’t anyone tell you you’re supposed to eat complex carbs and not simple ones? I am not trying to be a dick, I am being wholly fuckin’ serious.
