    Please feel free to post any ask-the-doctor type questions here in the comments section and I’d be happy to try to answer them. And check out the other videos on industrial toxins. Also, there are 1,449 other subjects covered in the rest of my videos–please feel free to explore them as well!

    super interesting

       Is it known where these toxins originate? Are these purely environmental
      for all animals regardless of how they’re raised, or is there something in terms of the industry’s processing and
      that perhaps leads to these levels?

      I had the same question regarding the endotoxemia videos. Could that be a
      result of the rapid pace sloppy butchering practices seen today in
      industrial scale slaughterhouses? Or should people buying local,
      small-scale, carefully butchered animal products be just as worried?

      It’s just that I find that the typical response to any of these
      studies from omnivores is that all negative issues are negated by eating
      grass-fed, organic, free range, etc, etc.

      I wish researchers
      would start to address this as the grass-fed/organic/etc movement grows
      and more and more consumers grow to see it as the “safe and healthy”

        Grass fed organic beef does not negate the issues seen with consuming meat. As we will see in Dr. Greger’s fure videos putting wild game to the test compared with typical agriculture, the wild game still causes an inflammatory response. chronic inflammation is the cause of todays common degenerative diseases so to eliminate this we must adopt a whole foods plant based diet.

        Looking at the most long lived populations, such as the okinawans who had the most cenetarians per capita, their diet had very little meat. Here is an anylasys of their diet.

        Okinawan Diet, and Healthy Aging

        Data derived from analysis of U.S. National Archives, archived food records, 1949 and based on survey of 2279 persons.

        Some points

        Their diet was 85% carb, and 6% fat. Sweet potatoes (a Japanese sweet potato) made up almost 70% of their calories. Nuts were less than 1% of calories (the equivalent of 1/10 of an ounce a day) Oil was less than 2% of calories (which is about 1 tsp a day) and sugars were less than 1% of calories (less than a tsp a day)

        The total animal products including fish was less than 4% of calories which is less then 70 calories a day. That is the equivalent of around 2 oz of animal products or less a day

      And also, allow me to say thank you. I’ve shared a number of your videos (especially Uprooting) with family and friends. I can’t tell you how wonderful it is to hear nutritional info based on actual journal articles. But truly this website is so important. And also, I really appreciate and respect your tone, as in you’re not afraid to say when the jury’s still out on a topic or when *gasp* there’s a plant food that’s not so hot for our health. Your impartiality is a breath of fresh air. (Please!) keep up the great work!

    I read the book by Neal Barnard, M.D. and nutritonal researcher, Foods That Fight Pain after a neurosurgeon to whom I was referred asked me if I ever considered cortisone steroid injections in my spine. That made me cringe. I knew that cortisone steroid damaged the immune system and was also linked to osteoporosis, and wanted nothing to do with this. I fractured the lumbar (5-L)region of my spine in March of this year, and neither wanted surgery, steroid injections in my spine to reduce pain, nor recombinant DNA, and was open to a diet change.
    After eliminating dairy, meat (all flesh and of course fats, from animals), wheat, corn, [sugars were already gone], so-called vegetable oils, nuts, and eating lentils, beans, rice or quinoa, certified organic everything, especially tofu, 3 high quality fruits per day including 5 figs, lots of calcium rich veggies, but all high nutrition veggies, I found that the pain just disappeared and with it, I lost 60 pounds in 6 months. I have more energy than ever.
    Began taking certain supplements recommended by Dr. Andrew Weil for bone support. Dr. Weil believes in mostly vitamins from food, but adding certain supplements. I was eating 1000 mg of calcium per day, and ingesting about 400 mg calcium citrate; 2,000 IU of vitamin D from wild, Alaskan sockeye salmon, krill oil.
    I knew where organochlorines came from from my years as an environmental activist and avoid animals high on the food web. The salmon I was getting were small sport fish, not large salmon and always wild from Alaska. However, I limit my fish meals because of dioxins, PCBs, and organochlorines.
    I have not read your talk, but I was hoping for any input on how my diet looks to be. I’m eating roughly 5-6 cups of broccoli, or bok choy, or kale, or collard greens per day, adding sweet potatoes or yams when I avoid rice. Eating oatmeal with certified organic low fat tofu and figs for breakfast, along with an orange, strawberries, grapefruit, or other citrus.
    My supplements are always taken with meals.
    For exercise, I’m trying to build up with weight bearing to reverse my osteoporosis as I do not want to do recombinant DNA Ibandronate –Boniva. I’m trying hard not to eat GMO’s and pesticides, I don’t want to swallow or inject recombinant DNA pharms. Don’t trust them!

    Interesting, thankyou;

    Hi Doc. Ok, I get it, don’t eat any chicken or meat for that matter. BUT here is my tiny little problem, “I am a Vietnam Veteran who was sprayed with Agent Orange for over a year and now I’m suffering the long term effects. What can I and so many others do to get rid of this crap from our systems?” By the way, where I was stationed, we also were sprayed with JP-4 every time a jet came in to land at Da Nang Airport. (ya godda love Monsanto & the US government).

    • Thea

      Richard: I’m so sorry to hear about what was done to you. It’s not fair and it sucks. Unfortunately, I don’t have any actual help for you, but I wanted to express my sympathies and my hope that someone will have some good ideas for you. Good luck.

      • Richard Frazee

        Hi Thea, listen, every time I walk through the valley of death, God tells me, “Don’t sweat the little things.” This is another one of those little things, so I’m not gonna sweat it, but I would enjoy knowing what I can eat to clean all that crap out of my arteries. I’m grinding a tablespoon of Flax every morning for my Smoothie and adding a teaspoon of Amla to it as well. About the only thing I’m almost not willing to give up are my cigarettes, but maybe time will change that too. I am on a first name bases with Kale, red beans, garlic, ground cloves & cinnamon and a bunch of other good foods. Another thing, my time has long ago passed, show your pride and sad feelings for the men & women coming back now. They deserve it a lot more than me. I just did the job I was trained to do. Simper Fi, my brothers & sisters, Simper Fi.
