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.

      Eh. Parents don’t usually give their kids soda for breakfast, even if juice has a comparable amount of sugar.

      They also don’t give their kids candy for breakfast, but cereal and pastries are okay.

      This shouldn’t have to be spelled out for you, but many people believe that juice is good for you.

      Make sure to check with your doctor if you’re on any meds! Grapefruit juice can cause you to absorb more of your medication and can cause overdoses.

        The most common drug it messes with is caffeine. Even a little grapefruit juice will make the effects of caffeine far more pronounced.

    I was raised to dilute it with water to get “more” of it.

    Something interesting is that the article doesn’t differentiate between “from concentrate” and “fresh juice”.

    It’s “no added sugar” metric is flawed too because that likely doesn’t count Aspartame, or other alternative sweeteners, as the Nutrition facts do not count them as sugar either.

      no added sugar is true - but it doesn’t consider that 100% fruit juice has a metric SHIT TON of natural sugar in it. A glass of 100% orange juice is roughly the equivalent of something like 6-8 oranges.

      That’s because aspartame has not got the health impacts of sugar. It isn’t sugar. So if you added aspartame, you’re not adding sugar.

    Everyone has been on this tangent for years, this isn’t exactly news. I think it’s worth noting that the problem isn’t really this simple. They concentrate the juice and pump it full of “juice” that is really just sugar. If you actually buy real pressed 100% blueberry juice, for example, instead of apple sugar flavored with blueberries, the sugar content is lower. And because you would never actually want to drink 100% blueberry juice because it wouldn’t taste how you are expecting, you would water it down. Suddenly you have a glass of juice with 5 grams of sugar instead of 30 grams and you are fine. Additionally, no matter the type of juice, it is nearly always over concentrated because they are trying to boost the sugar content. People should really be watering down any kind of store bought juice.

    No one is actually drinking “100% juice”, they are drinking a product that resembles the fruit of juice. These companies are not squeezing juice into a bottle, they are concentrating fruit sugars and adding them back into water. The problem is just as much with false advertising as anything. I’m not saying freshly squeezed juice is healthy, but it as sure as shit healthier than the fraud they are selling on the shelves. As with everything, the problem is money. Companies know they will sell more if they say it’s juice and then pump it full of extra concentrated fruit sugar.

    Edit: I wish more companies sold actual 100% real pressed fruit juice, I would buy it and water it down with soda water. I also wish they were more honest with their labeling about what they are actually doing. Not everything needs to be flawlessly healthy, but we could take steps in the right direction. You should only be able to label something as 100% juice if it actually is squeezed out of the fruit and put in the bottle with no interference and additional processing.

      Some of the best drinks I’ve ever had are pure fresh-squeezed juice.

      For example: pomegranate juice pressed by a street vendor? Amazing. Apples from the tree in my mom’s yard? Incredible when juiced. Freshly squeezed orange juice? Sign me up.

      Relatively few fruits make a juice that’s not good straight. Cranberry comes to mind as being too bitter. Lemon is a bit too acidic for most.

      Wyman’s 100% blueberry juice is 20g sugar per 250ml. Mott’s apple juice is 28g for 8 oz/240ml. So blueberry juice is about 2/3 the sugar of apple juice. It’s still plenty sweet.

      You don’t water blueberry juice down because it’s not sweet enough. You water it down because 8oz of Mott’s apple juice is $1.30 at Walmart, and 8oz of wymans’ blueberry juice is $7.30. Blends use apple juice because it’s cheap and mild, so you can layer other flavors on top.

      Juice isn’t bad for you because of the extra apple sugar. It’s bad because you removed all the fiber. Fiber promotes sateity.

        Upvoted because they are all good points. But I would say, that even these pure juice blends are absolutely concentrating the sugar, and probably using the sweetest varieties they can find. I would put money on it. I’ve pressed juice myself and it is never as sweet as what they sell you in the store, not even remotely close. The store juice is magnitudes more sweet because they are liars and frauds, full stop. Either way, we should all be watering it down. Unless you’re desensitizing your taste of sugar by eating pixy stix every day, most juices are too sweet anyway.

          and probably using the sweetest varieties they can find.

          It’s probably a mix of using sweet varieties, picking at peak ripeness and quickly juicing them without much transportation.

          Think of the difference in if you made tomato juice with a standard supermarket tomato vs a local in-season farmstand tomato.

          Either way, we should all be watering it down.

          Honestly, juice just isn’t anywhere near as healthy as whole fruit.

          You can water it down if you want, but either way it should be a fairly rare treat.

          I believe I have bought those same brands. If I remember, they come in 32 Oz bottles and are extremely tart. I would water them down heavily and give them to my daughter and she was able to tolerate it.

    Our entire food industry is dedicated to high carb foods that generate more profits. Many, many people cannot handle a high carb diet and wind up fat, or sick. A much lower carb diet, including healthy fats and lots of fiber, lessens obesity, heart problem and diabetes. Been there, done that.

      Carbs are not bad for you, obscene amounts of sugar is. Yes you shouldn’t just eat nothing but carbohydrates, but your body needs carbohydrates to fuel the muscles. Around 100 grams a day is considered the minimum you need to eat typically.

      My GF is type 1 diabetic so I have to be aware all the time of how much carbs are in things. It’s actually insane. A glass of OJ has as much carbs and a can of soda for instance. A glass of wine has ~100-120 calories. Breakfast cereal is essential just carbs and sugar.

        Breakfast cereal has evolved into a “new” market for candy makers… Reese’s cereal?? Just brand it as breakfast and people somehow think they’re not feeding their kids candy for breakfast… I used to buy that kind of stuff for a dessert snack lol

      Not all carbs are the same. Fruit juice is simple sugars with little to no fiber.

    Why specifically 100% fruit juice?

    Edit: I learned to read. It’s because of the no added sugar.

    Added sugar is a problem when it’s added to things that don’t need it. The best way to mitigate this isn’t with a sugar tax, but to tax per calorie in the finished food for any amount of added sugar.

    I read the whole article and all it says is that the weight gain is due to the lack of fibre in juice, which leads to not feeling satiated

    So the weight gain is due to eating other things on top of the juice, no?

    • Dark Arc

      No, the weight gain is from the juice being high in sugar (like a fruit) without fiber (which a fruit has).

      You’re basically drinking sugar and there’s nothing to slow down your metabolism or fill you up, so you take in too much sugar.

      In theory if you mixed it with something fibrous like oats (that don’t have their own sweatener) maybe you end up in a better place (if you drink less juice and you eat/drink less caloric beverages/food throughout your day – i…e you trade bland oats and orange juice for a hamburger).

      In general, adding things to your diet doesn’t help unless you’re also removing something (e.g., adding smoothies is great! … but not if you’re still having the hamburger and now also a smoothie vs water).

        That seems like exactly what they said. 100 calories of fruit or fruit juice is the same in one sense. However, the fiber in the fruit makes you feel more full so you may not eat more. Being more hungry with the fruit juice could potentially make you eat more.

          Hm… I think I misread/misinterpretted.

          I’d still caution against the idea of eating something “bad” but making it “good” by pairing it with something “good.” That’s a seemingly common slippery slope.

      One glas of OJ is like the juice of 10 oranges. You simply wouldn’t be able to eat that many because of all the bulk (fibre) that comes with it. But as juice, you can down them in seconds, giving you more sugar than a soda, which will lead to bloodsugar spikes, which will lead to Type 2 diabetis. So eat as much fruit as you like, it’s super healthy, but don’t drink fruit juice.
