Why Your Green Juice Might Be Just As Bad For You As a Candy Bar

Why Your Green Juice Might Be Just As Bad For You As a Candy Bar

Twee names, artisanal glass bottles, staggering prices—yep, juicing has gone mainstream. Once the purveyance of health food nuts, liquified veggies and fruit have now become so popular that even coffee shop chains hawk veggie and fruit juices along with their cappuccinos and white chocolate mochas. 

But grabbing a green juice to offset that indulgent caramel frappaccino isn't actually a healthy strategy–it's time to end the futile attempt to balance health with a shot of veggie juice. As it turns out, that spinach-apple-pineapple juice could be just as detrimental to your body as chomping down on a candy bar.

The average cold pressed green juice usually contains green vegetables (like kale and spinach) plus some sort of fruit (like an apple, pineapple, or lemon). But the addition of that fruit juice can take the total sugar count up to 25 to 35 grams—even more than a Snickers bar.

Juicing is the process of extracting all the liquid from fruits and vegetables and leaving behind the pulp, skin, and core. And yes, you’re getting some good stuff from the juice of produce–in fact, 90 percent of the nutrients from produce are found in the juice, according to the Department of Agriculture. Great! Juicing also makes fibrous fruits and vegetables easier to digest, which can be a godsend for people with digestive problems such as gut damage, IBS, or Celiac's disease.

Raw fruits and vegetables contain some beneficial enzymes that are neutralized in the cooking process. That means the only way to ingest those powerful enzymes is to eat or drink your produce raw or lightly cooked. So a straight shot of nutrients to your gut can certainly be good, but there are also some less than ideal effects that juicing can have on your body.

Though you probably think of fresh strawberries, kale, and carrots as full of vitamins and minerals, all fruits and vegetables are mostly carbohydrates, fiber, and a minimal amount of protein (we're talking one gram or less). These carbohydrates mostly come from fructose, the sugar that naturally occurs in produce. Every type of sugar—white sugar, raw sugar, honey, agave, fructose, to name a few—causes the body's blood sugar to spike. When sugars aren't combined with fiber, fat, or protein (which all take a while to breakdown and digest), they hit your bloodstream hard and cause stress in the liver, spikes in insulin production, and inflammation in the body.

Whether it comes from a piece of fruit or a brownie, your body reacts to sugar the same way. However, you can offset your body's reaction by choosing foods that have more macronutrients like protein and healthy fat. A large apple has 25 grams of sugar—the exact same amount of sugar in a Milky Way candy bar—but because the apple is also full of fiber, the body can break down the apple more slowly than the candy bar. This means you'll feel more sustained energy for hours after your snack—without the sugar crash.

So remember the pulp left behind in the juicer? That fiber is what keeps blood sugar from going berserk when you chow down on a fruit salad. When you eat fruits and vegetables in their whole form, the fiber allows your body to digest that fructose without any serious issues. When you extract the fiber through juicing, your body treats fructose similarly to other simple sugars.

If you're otherwise eating a balanced diet, one juice a day isn't a big deal. Overconsumption of fructose, however, can damage in the liver, similar to the effect that toxins like alcohol have on your major organs. Another downside of too much fructose? It can permanently destroy your metabolism, making it harder for your body to process food and calories in the future.

Still want to drink your daily quota of veggies? Go for a blended smoothie instead. You'll get all the juicy benefits of the vegetables and fruits, while still knocking back tons of fiber and nutrients from pulp. If you just can't quit that green juice life, drink your beverage with a meal to better help balance your blood sugar.

Being a Picky Eater Might Have Unexpected Consequences

    Thanks for this. When I realized how much sugar I was taking in from all the fruit juice I was drinking, I cut out the Mango Tangos and other smoothies that I thought were good for me. Now I look at the juices on WF's shelves and eliminate all that have fruit mixed in - which is 98% of them. I'm buying only all-vegetable juices, knowing that carrots have a high sugar content, too. The ones with green vegetables only are more expensive, but I feel like I'm getting more bang for my bucks.

    This article is misleading, at best. Thanks for encouraging people to eat candy bars, which are full of dubious ingredients, besides sugar, not to mention lacking nutrients of green juice. Also, yes, sugar from fruits does cause blood sugar to spike, but it's by far a better choice than a candy bar, if you are going to eat something sweet anyway. This kind of click-bait sensationalist media is irresponsible.

      I read the article and in no way is the author suggesting that people chump on candy bars. What is misleading is that people think juicing is healthy, when it is not, especially being that the fiber is not included. What this article is alerting people to understand is proper NUTRITION. We need the fiber in fruits and vegetables to benefit wholly. The main point here is THE BODY TREATS ALL SUGARS THE SAME (from candy bars or whatever), its the fiber that makes a difference. Include the fiber by making SMOOTHIES instead of JUICING.

        I agree with Meg that the article and headline were written too sensationally. It's one thing if it just said "which has more sugar," rather than that it's "as bad for you as a candy bar," also disregarding, as comments below noted, the often significant differences between homemade and storebought juices/smoothies. Clearly to bring attention to the amount of sugar in some juices and smoothies, especially when fiber-poor, is a good thing, but the claims are too far to be reasonable, such as when she initially states that "from a piece of fruit or a brownie, your body reacts to sugar the same way," when that's clearly not the case, because as she does then get to at the end of the paragraph, the fruit also has fiber, which means your body DOES NOT process the sugar in the fruit the same way as a refined sugar treat. Sure, Meg was being sarcastic in her "thanks" line, but for people who don't read all the way through the article, which are probably many, that could pretty much be their takeaway.

          You make a good point that most people are not reading the whole article and digesting (no pun intended) it. Not to pat myself on the back but I have taken some nutrition and physiology and exercise classes at my local college to be knowledgeable when it comes to how sugar is treated in the blood stream (NOTE specifically in the blood stream and not the whole body). It is the results from the blood stream that effects the body. So again whatever, we consume that have sugar in it, the blood stream will react to it the same way. The chemical composition of sugar does not change when it enters the blood stream no matter the source, whether be it from fruit, vegetables (and yes some veges contain sugar), candy, soda, etc. etc.

      I think all of you who are being misled by this fad called JUICING are missing the point of this article. One word FIBER. Without fiber which is extracted from juicing you are basically just drinking straight CARBS no fiber. If you like your juicing and still swears by it add some flax, and some form of fiber and then you will be OK. Do not be misled to think that just juicing w/o the fiber will help you the long run. It just will not help you w/o the FIBER or some healthy fat as in avocados, flax, etc.

    Just another Blogger paid by the "Sugar" Food industry to do some damage control and debunk Juicing. Put it this way, How many Facebook Candy Bar Diet pages are there, that show people losing 100's of lbs in weight everyday?...Now have a look to see how many Juicing Facebook pages there are that show people losing 100's of lbs everyday? Surely if the Snickers Bar has less sugar than a Mean Green, then they must be losing alot more weight....right?...I mean, thats right isn't it?.....lol...load of rubbish..

      Loosing weight does not make you healthy. Why is everyone who is replying missing the point of this article? The author is not suggesting that you eat candy bars. Stating facts can hurt feeling but facts are facts. All the author is saying is that JUICING extracts the FIBER that balances the SUGAR when it gets into the blood stream from fruits and vegetables that are juiced. Please read the article again!

        The article is misleading by implying that using "Juicing" as part of a weight/health control diet can be pointless, as the juices contain as much Sugar as a Candy bar. First of all, if you are just buying prepared Juices off the shelf, then this may be the case, but it doesn't really make that clear. Juices that are pre-made, bottled and marketed this way do tend to contain a lot of fructose sugar, as they are very heavy on the Fruit. Anyone who follows a correct Juicing plan will understand this and steer clear of them. On a correct Juicing plan, where you make your own Juices, you stick to a guideline that says there must be an 80:20 Veg:Fruit balance, in order to control the intake of sugar. Also, it doesn't go into any detail of how Veg and Fruit nutrients are absorbed into the body, and are generally used up by normal daily physical activity. Not physical exercise, but physical activity, i.e. Walking, Housework, Working, Hobbies and so on. If a person also takes regular Physical Exercise, which is always recommended, then any sugars taken into the body will be used up within the first 20-30 mins of a workout, and therefore not stored. If you are going to write an article on Juicing and its effects and how it compares to other food stuffs, then it should be done in context. This is not the case here. Its presented as a "Shock" article, to imply that Juicing is no better than eating other sugar laden products. There is a massive difference between refined, concentrated white sugar and the natural sugar found in fruits, irrespective of how they are consumed.

    I happen to completely disagree with the article. First of all everyone knows the sugars in fruit are different that the sugars in candy bars (natural vs. unnatural), plus you're not getting all the fat that is in the candy bar or the GMO, if you're using organic/non GMO fruit.And the difference with a blended smoothie is that your body works hard to digest the fiber, whereas with out the fiber your body soaks up all the nutrients right away. This is why so many people are losing weight and curing diseases with juicing. And I sip my green juice, that I juiced myself as I type this up. I really wish Thrive would get better writers...

    I don't think some of the people commenting are reading the entire article. This goes into how your body processes sugar. When you eat an entire fruit or veggie, the fiber helps your body process the sugars over a longer period of time. The author even goes on to say that with a balanced diet, one juice a day is fine! I think this is meant for people who are just starting to refine and reinvent their eating habits, and who may think that a juice cleanse for a week is the best thing for their health. Also, when you juice at home you can control what goes in there - you probably are adding one apple and not an apple PLUS some more fruit juices (as some juice and smoothies shops may do). Juices are great! But so are whole vegetables and fruits..chewed up and swallowed the old-fashioned way ;)

    All juices are not created equal, dear author. If you look at sites like Reboot With Joe, you'll find out that homemade juices should be 80% veg and 20% fruit (I actually prefer 90% veg to 10% fruit) and for the record, not ALL the fiber stays behind - only the insoluble kind. There's plenty of soluble fiber that's too small to get filtered out and it has the cleansing/mediating effect desired. To lump homemade, mostly-veg fresh juices in with commercial, mostly-fruit juice blends is irresponsible and misleading at best and downright damaging at worst. I agree with the responder who called this kind of headline and partial (mis)information sensationalistic.

      Thanks for your comment! I definitely agree with you that not all juices are created equal, and I think it’s fantastic that you’re juicing with mostly veggies! As mentioned in the article, juicing vegetables with a small amount of fruit is a fantastic way to get micronutrients delivered immediately to the body. What some who might be newer to juicing might not realize is that juices made with lots of added fruit (instead of veggies) are packed with sugar, so if you're looking to avoid ingesting too much sugar, lightening up on fruit is probably a good idea.

      Bravo! Reboot with Joe saved my life. I'm off all medications, my doctors can't believe how perfect my numbers are, I feel great. Juicing using the 80/20 rule will not raise blood sugar to harmful levels (I test often). This article is irresponsible hyperbole and a poor reflection on Thrive Market.

    So, I consider myself very knowledgeable about nutrition. Thank God the autoimmunity I developed is now dormant, partially because of nutrition changes. I tend to look for the positive in everything. This article uses extremism and sarcasm to get the readers to realize how excess sugar intake through juicing and candy can be harmful. You can find tons of articles about the damage caused by GMO, but you rarely read about the cons of excessive juicing. Its all about diversity of food, great digestion, and using knowledge to make good choices. Also, if you have high inflammation, chances are you may have candida overgrowth that is fed by sugar. If you have inflammation, try green smoothies for now with only green apples and lemons with veggies - no other fruit. If not, you can alternate between smoothies and juices.

        On the grounds I've been juicing for a couple of years now, I feel somewhat qualified to comment as it happens. There is nothing libellous nor defaming in my comment, the article is bollox. Suggesting Fructose and sugar are identical is bollox, saying a snickers is better for you than a green juice is also bollox. It is just full of sugar and fat with no nutritional value at all. The article fails to mention that the best way to get phytonutrients of any amount is via juicing. The article has no foundation of truth at all.

    I thought this was a great article taken as a whole and not in part. Your point was to ditch the juicer and use a blender instead. Not to eat candy bars instead of fresh juice. I think a few commenters have jumped to conclusions, instead of patiently reading the whole article before forming opinions. It may have been helpful presenting your point if you had stated the obvious that, vitamin rich juice is still a better option if you were going to eat a candy bar anyway. You know, for those who don't know it's obvious to everyone, not just him/her.

    I have read through the article and the responses below shows how people can twist the meaning of things to suit what they strongly believe in. The facts in this article boils down to this: Juicing extracts FIBER out of the fruits and vegetables. We need fiber more than we need the left over sugar which hits the blood stream like and other sugar. The blood stream does not discriminate against sugar. The chemical formula of fructose is the same from fruit to table sugar and any other form just like the article points out. That how the blood stream sees it. Without the fiber it cause sugar in the blood to spike, and that's what you don't want. There is no suggestion to stop juicing and eat Snickers bar, just do smoothies which will include the fiber. BTW make smoothies with either water or unfiltered coconut water straight from a coconut.
    GREAT ARTICLE if you get the POINT!!!!!

      One of the main reasons people Juice is for the Health benefits of absorbing the micro-nutrients on Veg and Fruit. Yes, Fibre helps with the breakdown and slow release of sugar into the body, but it also reduces the amount of nutrients we can absorb. In order to flood the body with micro-nutrients in the quantities it requires to start healing and rebuilding the cells required, Juicing is an excellent method as the Nutrients are absorbed within 15-20mins of ingestion. To get the same amount of Nutrients through eating a balanced solid food diet, you would infact be consuming way past the normal daily calorie intake, and in turn defeat the object. People forget that weight-loss is a by-product of Juicing, and that many people do it for health reasons and not just a quick fix to losing weight. The article is written out-of-context.

        A smug smart ass eh? (You want some attention? Okay!) Well First of all nc, No one is implying the globalized "Good" or "Bad" of anything, let alone natural foods. Go suck on some natural Hemlock why don't you. Secondly, to try to categorize me as "one of the people the food..." You obviously must be the type who likes "blog beef" to try to take personal shots at someone you don't even know. Supremely Egoic and cowardly gesture! Lastly, The wise choice is not to only look at Low vs. High glycemic carbs as opposed to Simple vs Complex carbs. To be wise I'd suggestion one take all the valuable information into consideration, including the metabolic differences between refined (snickers) sugar and naturally occurring sugars in various fruit. #EaseBack!

      Thanks for your comment–of course, we’d never recommend choosing a candy bar over a piece of fruit! Yes, fruit contains natural sugar in the form of fructose and sucrose, and a piece of whole fruit is metabolized differently in the body than a candy bar. When it comes to fruit juice that doesn’t contain very much fiber, blood sugar spikes the same way it does with other sugary drinks and foods.

    Excellent article and I totally agree. I've been into organic and clean food since the 1970's and I knew this to be true then. Juicing is not whole food............it's sugar. Smoothies are a better choice. (but leave out the high sugar fruits!)

    The benefits of adopting a lifestyle that includes 1 to 2 days per week of drinking only freshly extracted, natural juice have completely changed my life. I'm not a doctor, nor a nutrition expert like Michelle. I am a 51 year old ultra-marathon runner who is willing to experiment with health and fitness, and keep what works. Natural fruit and veggie juices, including the green drinks mentioned in this article are nothing short of "life-changing". I have completed five 7-Day juice cleanses in the last year, drinking only freshly-extracted juices and blended smoothies following Jason Vale's 7 lbs in 7 Days Plan. I have run 28 miles on day 5 of a juice cleanse. I participate in strength training programs and spend much time outdoors engaging in physical activities. I've found that juicing is "not" a detriment or a danger to my health. I used a tried and true program as a starting point. I suggest Jason Vale (Movie: Super Juice Me) or Joe Cross (Movie: Fat, Sick and Nearly Dead) for examples. I am not overweight. I simply tested Jason Vale's claim that the sugars in freshly extracted juices are not the same as those found in processed sugars. Check out Jason's rebuttal to a similar juice-unfriendly article here: http://news.juicemaster.com/jason-vales-reply-to-the-mail-online-article-juicing-can-wreck-your-looks



    I encourage everyone to test for yourselves the benefits of integrating a slow juicer (Omega VRT series for example) into a daily lifestyle routine using a true-world, tested by humans, program (see Jason Vale or Joe Cross), What you you got to lose?
