Doctor's Note

The reference to pollutants in mothers' fat is from Friday's NutritionFacts.org video-of-the-day Pollutants in Californian Breast Tissue. The dozens of chemicals found in the bodies of pregnant Americans is explored in CDC Report on Environmental Chemical Exposure. For more on which foods appear most contaminated, see yesterday’s NutritionFacts.org video-of-the-day Food Sources of Flame Retardant Chemicals. I have 30 other videos on eating for healthy pregnancies, including Dangerous Advice From Health Food Store Employees, Preventing Childhood Allergies, and Pregnant Vegans at Risk for Iodine Deficiency. Even if we do pass a load of pollutants onto our babies, how long does it take their bodies to get rid of them? That’s covered tomorrow in How Fast Can Children Detoxify from PCBs?

      Dr Greger, why didn’t you mention the following finding of this study “Vegetable consumption was also associated with lindane and fruit intake with endosulfan I.”?

      • Consumption of vegetables can lead to ingestion of pesticides and other chemicals if the vegetables are not washed. See the nice post by R Ian Flett to help explain why you don’t find the fat soluble persistent organic pollutants inside plants. They transport material primarily by water whereas our blood stream has fats and is capable of transporting fat soluble substances to our fat cells. Looking at the big picture the consumption of an all plant diet eliminates greater then 95% of pollutants.. buying organic minimizes your exposure further and avoids GMO exposure as well. The latter subject is particularly worrisome due to lack of human studies, complexity of the issue, corporate interests, etc.. For more information on avoiding the latter you can go to http://www.nongmoshoppingguide.com/. Next Tuesday we in California have the opportunity to require labeling which will allow consumers to more easily avoid GMO foods. Jeffery Smiths organization, Institute for Responsible Technology, has produced a 1 1/2 hour movie, Genetic Roulette, which is available for free watching through November 6 follow link on website, http://www.responsibletechnology.org/. I’m not a fan of studies which use the term “Mediterranean Diet” since the diets consumed by folks who live around the Mediterranean Sea are varied.

      Hi. DDT is widely known to have saved millions of lives who otherwise would have died of malaria. Likewise the ban on DDT meant the death of many millions of people from malaria. I would rather have DDT in my system than die of Malaria. Now of course, I don’t live in a part of the world where malaria is present, but so what. I think it is wrong to attack DDT. In fact, some people who have promoted the banning of DDT were also linked to an ideology of “population reduction” to “clean the earth” of human “overpopulation”. So what might seem a bit harmful in a developed part of the world, because it is not “natural”, might be very beneficial or, rather, crucial in other parts. Of course that means that the whole world should be developed so that malaria and other diseases will vanish for good. That is a whole other discussion in itself. Anyway, chemicals are not necessarily bad, just as machines, nuclear power, radiation, genetically modifying and so forth also aren’t. If we use these in a wise way then the benefit can long outweigh the potential damages. That of course is a moral question as well. Maybe we could get a video about what foods boost our morals :-) – I’d appreciate comments to my message. Thanks

    You down with DDT, yeah you know me.
    You down with DDT, yeah you mommy.
    You down with DDT, yeah you homie.

    Who’s down with DDT, every last baby!

    Sad but True.

  • Nothing to do with this video, but could you ask your web designer to add a “play random video button”? That would be cool :D.

    The video says that these chemicals accumulate in fat.  I wonder if the researchers looked at a link between nut consumption and DDTs in the blood since nuts are high in fat. 

    Not that I would stop eating nuts.  I’m just curious how much of the DDTs are in nuts vs the animal foods.  Partly I’m thinking about another Dr. Greger video (which I wish I could find again – anyone?) that I believe talked about these chemicals getting more concentrated the higher you move up the food chain.  Based on that, I would guess ahead of time that nuts would not be as affected as meat, fish and dairy.  Just a guess.

    • R Ian Flett

      You raise a very good point. How do vegetable fats compare with animal fats in regard to toxin accumulation in general? The veggie fats are usually encased in a protective shell (nuts, avocados, legumes) so that toxins enter via the roots, whereas leaves can absorb them more directly. Animal fat is efficient at storing toxins, which is why it’s correlated with many cancers.
      When we burn off fat it’s like boiling off steam. We are left with higher concentrates of residues. It’s often said that rapid weight loss overloads the bloodstream with toxins stored in the fat and can trigger cancer. It’s better to lose fat slowly and let the body detox at a rate it can cope with.

  • Reminds me of the documentary “Homo toxicus”.

    Could you post a link to your video regarding cleaning and getting chemicals off vegetables? I know I saw a title regarding this but I’m having no lick finding it. Thanks a lot for all your work.

    Dr. Gregor,  Thank you for your awsome wotk, bringing clinical nutrition research to those that need it most.  However, the TED,COM talk (below) questions whether we are getting the whole truth from the literature, or only those papers that reinforce the a priori notions of the publishers.  Being from the Humane Society, I’ve started  wondering if there might be a selection bias here as well.  I’ve adhered to a fairly strick plant based (my physician calls it an anti-inflamation) diet.  So, I hoping if there is a bias, I wont need to back out that much.
