Doctor's Note

How long does it take to reduce one’s body load of antibiotics from meat? Just days! See Lowering Dietary Antibiotic Intake. Our exposure to drugs given to chickens and turkeys may be one reason that poultry consumption has been associated with significantly higher lymphoma and leukemia risk; see EPIC Findings on Lymphoma and Chicken Dioxins, Viruses, or Antibiotics? A Carcinogenic Retrovirus Found in Eggs (and poultry) may also be playing a role.

      Love it! It’s easier to notice your other available information with the columns on the first page. Would still like to see your commentary placed first, above others. In Firefox, on my Mac, there’s a couple of comments ahead of yours for this video.

      • Thanks so much for the feedback–I deleted it down here and put it up in the new Dr. Greger’s Notes section so it will always be visible up top!

    I know you are big on plant based diets. However, i do not eat grocery/production meats. All meats in the grocery stores are from factory farms. i raise my own chickens, eggs, ducks, geese, cows, goats, all on pasture and no antibiotics or GMOs. They are all free pasture ranged. I am 58 and very healthy and i eat some meat every day (my home grown stuff). So i think that healthy diet has more to do with how our food is produced/grown/fed, than actually WHAT we are eating. I also eat all my own garden veggies & fruits (no pest/herbicides) and if i purchase, then i try to only purchase organically grown.

      RJ: I applaud you for trying to eat healthy. I also encourage you to watch more videos on this site so that you can improve your healthy eating. There are some things that are inherent in a food itself that no amount of production process changes. If you are interested, you can find all sorts of scientific information this site that explains the details.

      Good luck!

      RJ, I agree with you and your approach to food. The studies that Dr.
      Gregor discusses regarding factory farmed animals are really interesting
      but can not be applied to pasture/organic raised animals.

        Organically fed and raised are not allowed to be fattened up with antibiotics, and I don’t believe have ever had antibiotic resistant super bugs, which are caused in part by Glyphosate and the animal husbandry promoted by Big Brother to profit their bottom line. Although, the Obama Administration seems to be bending the Letter of the Law when it comes to organics, allowing more synthetic ingredients on the National List, which in turn allows Monsanto to manufacture “organic” pest controls using organic chemistry. Organic chemistry has NEVER been part of the National Organic Foods and Production Act of 1990. I only buy from farmers or sellers I know and trust.

        The Center for Food Safety has repeatedly litigated against the USDA’s bending of the National Organic Foods and Production Law and has generally won. And the Cornucopia Institute is a watch dog for Organically grown food and animals. Check out their web sites to learn of victories, or defeats.

        As a member of both entities, I urge you to join us with money and activism to save our food supply and fight back Big Bullies.

        The roof of my mouth either becomes numb or burns depending what is in the pesticides used on organic foods. This prompts me to write the company, if I have the address, or, not to buy from them again.

        It is either the Cornucopia Institute or the Center for Food Safety that has said that non-organic and non-sustainable farmers choose to ignore the urging of the government to feed their livestock the ground leaves and stalks from cotton, sugar beets, sugar cane and other crops, which are full of pesticides. This supersizes the toxins the animals eat. (No wonder my dogs kept dying at younger and younger ages every year since 1982.)

        All the major pesticide companies have supersized the amounts of pesticides on produce, as well as 100 ppm for fast growing Teff forage and hay. See: § 180.364 Glyphosate; tolerances in the right hand column of the Federal Register, and read the Conclusions at

        Fortunately not all farmers or ranchers use chemical agriculture on their pastures. Those that do was about 7%. Remember, the tolerance level is based on the Acute Effect and Glyphosate is a CHRONICALLY TOXIC HERBICIDE, it is not ACUTELY TOXIC. Hence, the tolerance residue levels don’t protect the health of the livestock as much as the health of the corporations bottom line.

        Organic farmers do NOT use chemical pesticides and only use biological controls sparingly. Organic farmers are the ones who pushed for a federal law! The problem is Greedy Opportunistic Predators who are also bullies driving farmers and ranchers out of business so we will have zero choice of what we eat or feed our animals.

        This is also the reason for the massive wolf slaughters, even of the nursing pups. It is so that the Greedy Opportunistic Predators in Congress can murder wildlife instead of eating factory farmed livestock. When Obama wined and dined contributors, he had his appointees roundup the wild buffalo (bison), separate the calves from their mothers, and head the adults for slaughter. This way the President could serve non-GMO meat to his benefactors. Disgusting!!!

    Should we give feedback on the new site here? Or is there a better place for it?

    I LOVE, LOVE, LOVE that the new site does not auto-start the videos every time you do something on the page. That’s a huge relief.

    On the downer side: One thing I already miss from the old site is the feature that shows the next 4 videos – including wrapping around. So, previously, it was very easy for me to go to the latest video-of-the-day, and see the next 4 videos on the right of the screen. Since it was the latest video of the day, the next 4 videos were actually the first 4 videos from Volume 1.

    Aside from just liking the feature of being able to scan 4 videos ahead at any point, being able to quickly find the first videos from Volume 1 was really important. Two of those videos are extremely hard to find via the Search feature, and yet I want to show those videos to people often and want to give people a way to get the “first one” and thus follow the whole set of videos in order if they want.

    Maybe I’ve missed it, but if you don’t already have such a feature, maybe you do this: Have links to videos by volume. For example, links like:
    Volume 1
    Volume 2
    Volume 3
    Volume 11 where the links take people to the first video of the volume. That would be great.

    Then, the wrap-around feature would not matter so much, but I would still like to be able to scan ahead and see much more than just 1 “next video” for videos in the middle of the series.

    Just something to think about.

    I wondered if this is true with organically raised chicken or turkey? With Thanksgiving in less than 2 weeks I will buy organic and spend the extra $$ if it is healthier.

    Interestingly, another study showed that in eating fish, darker meat consumption was associated with higher rates of heart attack. They gave no causative reason for this, however.

    Bugs! Did you just say bugs! Yikes. I feel itchy all over.
