    in our gym they sell 2 liter bottles of orangejuice. are there any negative health effects of drinking juice apart from not being as good as the whole fruit?

    and how about the added Vitamin C (as ascorbic acid) any potential negative effects from that?

    • Toxins

      Retail orange juice tends to be mostly a concentrated source of sugar, which would be my main complaint. The added ascorbic acid is not harmful and is equivalent to natural sources of vitamin c.

        also the juice in your gym is pasteurized.

  • ghulstyle

    and another question :D
    how does self pressed orange juice with all of the pulp added compare to the whole orange?

    • Toxins

      If you are throwing in all the pulp back after squeezing it, you are essentially eating the orange in a more liquid form. This is basically a smoothie, why not just do that instead in a blender as to not leave any extra pulp in the orange peel?

    I am having a problem in trusting this data. You would have millions of people who now juice fresh throwing away thier juicers. They all believe that juicing is in a concentrated form of nutrician. I would like to hear from them on this matter as juicing has been in the mainstream for awhile. I certainly have heard MD’s say that juicing was better for your health than all that fiberous plant bulk.
    I am wondering if something is left out in this final anaylsis.
    thank you

       It is widely accepted knowledge that juicing is no where near as healthy as eating the whole food itself. Throwing away the fiber and other nutrients that go along with it cannot be considered healthy. Fiber is essential for ones health and prevents diverticulitis, hernias, helps relieves ones body of contaminants and other disorders of the kind. If you can provide some evidence that juicing is better than eating the whole food then please do so. Dr. Greger has shared his data for viewing under the sources cited section.

        Juicing helps you absorb all the nutrients from the vegetables. This is important because most of us have impaired digestion as a result of making less-than-optimal food choices over many years. This limits your body’s ability to absorb all the nutrients from the vegetables. Juicing will help to “pre-digest” them for you, so you will receive most of the nutrition, rather than having it go down the toilet.
        Juicing allows you to consume an optimal amount of vegetables in an efficient manner. If you are a carb type, you should eat one pound of raw vegetables per 50 pounds of body weight per day. Some people may find eating that many vegetables difficult, but it can be easily accomplished with a quick glass of vegetable juice.
        You can add a wider variety of vegetables in your diet. Many people eat the same vegetable salads every day. This violates the principle of regular food rotation and increases your chance of developing an allergy to a certain food. But with juicing, you can juice a wide variety of vegetables that you may not normally enjoy eating whole.

          *Cited* evidence, please, not just regurgitated information from pro-juicing web sites and documentaries. Juicing may be better than not ever touching a fruit or vegetable, and it’s probably good for the temporary cleanse (based on anecdotal evidence), but *scientific evidence* shows it to be far inferior than simply eating the fruit.

          • http://www.facebook.com/bryant.kidd.7 Bryant Kidd

            please , post this “scientific evidence ” that you speak of, my information, though is well known in the community that does live a healthy lifestyle using raw juices from fresh vegetables and fruits, is also how I live my life, the evidence is in my own experience, and I do take offence to your “regurgitate ” comment, My friend, don’t speak of what you know nothing about.

    • Terischro

      I’ve also heard it said that most doctors are lacking in nutritional knowledge.

      • Kalidass10

        There are 125 medical schools in the US with only 30 requiring a course in nutrition. The average Doctor receives 2.5 hours during the entire eight yrs of education.

    Hi there, what about blending vs juicing vs whole foods. I am looking into getting my greens into my diet and was considering spending $800 on a commercial blender, but I don’t want to waste my money if the best way to get my nutrients is through the whole plant.

    • http://www.facebook.com/bryant.kidd.7 Bryant Kidd

      go to E bay, and buy a BlendTech, costs around $225, awsome blender, .. I make Kale green smoothies every morning, , feel great!

    • Toxins

      Blending is better than juicing, but eating the whole plant food is better than the 2. When you eat a whole apple you will stay full longer and feel more satiated over a blended apple although nutritionally they are equivalent.

      • http://www.eatandbeatcancer.com/ Harriet Sugar Miller

        Could you help us get to the bottom of this argument? Some people claim that blending and juicing on high speeds causes the plants to be oxidized, thus creating harmful compounds in your body. They say the best option is to juice at low speeds (single and dual gear juicers). How valid is that argument? Do the plants oxidize? That’s what’s happening when/if the juice turns brown, right? So if you drink it fresh, are all the anti-oxidants cancelling out any pro-oxidant effects?

  • jack

    what about juicing vegetables? If you are getting enough fiber by eating fruits whole, then to make it easier on your digestive system and to get in more than you could’ve normally chewed wouldn’t it be better to juice veggies?

  • Leon

    Has a lot of the lost nutrition got to do with oxidation and how much does blanding attenuate the nutritional value of your food? Also, does blending or juicing increase absorption and therefore make up for the overall decrease in nutritional value? Like to see a video blending vs juicing vs whole fruit’s, but testing the actual overall absorption of the food as opposed to just it’s pre-eaten nutritional value.

    • mikeysbro

      Indeed this video clip has a lot of missing information. Many juices like cabbage for instance loose 50% or more of their nutrients within a short time after being juiced. Though there was no mention of how long the juice was sitting around before it was consumed (it could have even been fresh squeezed o juice from the grocery store as far as we know ahem pasteurised and sitting around..). This makes a huge difference in nutrient content. (just like whole wheat flour has more nutrients right after being ground and later it drops) In addition, only one study at the beginning was mentioned as using real fresh squeezed juice. Furthermore different juicers may retain more nutrients than others. Although if one is drinking several cups in a few hours that would increase nutrient uptake.

      Obviously eating the whole food is going to be more beneficial than juicing because many nutrients are contained in the skin and underlying portions (bioflavonoids) but juicing does have a place when one is recovering from various pathological conditions. I believe juice fasting does help and here is an article about fasting and the immune system..

    Dude, you are the worst, most terrible person to listen to on a video I’ve ever heard… I tried really hard to sit through three of your horrible monotone videos filled with random high pitch voice fluctuations (yes that seems like an oxymoron, however, you somehow pull this off). I thought you were joking the first two videos, however, I now know you are not.

    This website is a really good idea. It has a great layout and is something I think could no doubt make you some good money. But you really need someone else to do these videos. Seriously, I mean seriously. And you have to change that goofy ass picture of yourself (I also thought that was a joke).

    Cheers

    • Thea

      Seriously. I mean seriously dude. You need to learn some basic manners. Your comment is unacceptable.

      Dr. Greger is doing the community a huge service. He does this for free/on his own time. If you are not mature enough to handle it, then seriously dude, I mean really, don’t listen. It’s your loss.

      Got it?

          Good call. I heartily approve. Thanks.
