    I came across your presentation to the Vegetarian Summerfest 2012 and really enjoyed it.  It’s nice to hear a doctor who believes in food as medicine.  We changed our diet to plant based last summer after watching the documentary Forks Over Knives.   It is the best decision we have ever made.

    Regarding this Juice Plus clip, I’m curious who the researchers are that are being referred to and would like to read the entire letter to the editor.   Would you please send the reference info.

    Can you give more information about the benefits or harm of dehydrated juice supplements? I find it hard to believe that there is any phytonutrition left after the processing and encapsulation.

      If you go to the Juice Plus website they reference dozens of peer reviewed studies supporting their claims. To his credit Dr. Greger is not selling anything, as opposed to some of the other internet physicians such as Drs. Mercola, Sinatra, Whitaker, et. al. However, I do think he tends to view things through vegan, antisupplement eyes. The Juice Plus website presents a pretty comprehensive view of their product and I think it is worth looking at. A single review or anecdote to me is not compelling.

        It’s pseudoscience mostly funded by the makers of Juice Plus. The only benefits are as overpriced vitamin pill. If you are really convinced of its nutritional value, consider buying Juice Festiv for 1/3 the price of Juice Plus.

    Knowing that barley is very good. Is barley juiced powder also nutritious?
    By the way, thanks for all you do.

  • Kathleen

    I would be interested in knowing who the researchers were that you quote in this video, please!

    • Thea

      Kathleen: This may not answer your question, but I thought I would make sure that you saw the “Sources Cited” link above. If you click the link, a list of papers cited in the video appears. And when possible, Dr. Greger links to those videos. Hope that helps.

  • Donna

    your Juice Plus info is dated from 2009 & 2010. Do you still believe what you state in these videos?? it is not a vitamin supplement it is whole food?? and where is the article on the American journal of medicine about the liver inflammation? I tried to locate it and could not, please if you would, provide the link… thanks

      You can read why the authors comment on the study consider juice plus a supplement

        The only conclusion that should be drawn from that peer review, is that further studies needs to be done to determine what changes in blood levels are “caused” by what, and that’s it. It asks questions, as it should. That is from 2003.

        One woman with cancer, and taking other medications that could have caused her liver toxicity. How much Ibuprofen was she taking prior to admission for cancer treatment? She may have been popping them like candy to alleviate the cancer pain. Using one case study to draw conclusions is nearly as faulty as using anecdotal evidence. I am sure Dr Greger understands that.

      Hey Donna, It’s quite misleading to say that JP+ is only concentrated fruits and vegetables. Go back to your JP+ Orchard and Garden blend labels and read them. Vitamin C, beta carotene, d-tocopherol, folic acid, enzymes, and acidophilus are all added back in after manufacturing. JP+ says that it is because the FDA requires that every label says the same thing, and they can’t guarantee that every bottle will contain exactly the same amount of nutrients (as you would not to be able to compare apple to apple, or cucumber to cucumber). Therefore, to standardize, they add nutrients the FDA requires they can ID by amount. Go to the Vineyard Blend label and see: L-arginine, L-carnitine, d-alpha tocopherol, calcium ascorbate, magnesium stearate, “natural enzyme blend,” coenzyme Q10, and folic acid. This may be just fine and all super healthy, but “it is not a vitamin supplement it is whole food” is incomplete at best. Also, though I have not read the studies myself, every independent review of the JP+ reports I’ve seen indicate that virtually all of them are inconclusive. I have been taking JP+ for over 5 years and honestly believe that it has helped keep me healthy. However, I am under no illusions that their marketing provides full disclosure.

        Very nice assessment.

    The naturopath I see trying to navigate the menopause highway found that most of my organs are stressed. My thyroid is stressed and the nutritionist in the naturopath’s office said that I could eat 1 Brazil nut daily in order to get adequate selenium. I’ve read elsewhere that 5 Brazil nuts are necessary to get sufficient selenium. I’ve started taking Nascent Iodine (2% strength) and need the selenium in order to work with iodine. Do you have any idea as to the combination of Brazil nuts and iodine? I appreciate your time.

    If one uses sources to back up a claim, it behooves one to read them. The second study cited from the Journal of Nutrition, “supports” the use of Juice Plus. I quote: “In the absence of dietary modification, supplementation with a fruit and vegetable concentrate produced responses consistent with a reduction in CHD risk.”

    I’ve tallied our grocery bill many times in the recent past, and separated the vegetables and fruits costs. We have spent well over $200 per person, per month, during our attempts to consume 10 or more servings per day. Juice Plus is $46 per person per month.

    My liver enzymes are normal.
