    If Dieldrin is accumulated in the environment – does is exists in plant foods as well?

    • DrDons

      Dieldrin and similar type chemicals are fat soluble and are much more prevalent and concentrated in animal products and are seen in greater concentration in humans consuming more animal products… see http://nutritionfacts.org/videos/dioxins-in-the-food-supply/. So although they can be present in some plants they are much less. Washing plants and going organic whenever possible will further lower the amount of exposure. Vegans have about 2% of exposure as those who are non vegans see.. http://nutritionfacts.org/videos/flame-retardant-chemical-contamination-2/. There is some good news as some of these compounds are decreasing in the environment… the bad news is that new chemicals seem to taking their place. Practicing the precautionary principle and following a low-fat plant-based diet with B12 supplement is the best approach.

    Dear doctor, I have a severe case of endometriosis, 10 years ago I’ve had a duoble intestinal resection (all the sigma, the ileocecal valve and 20 cm of large intestine)
    I am trying to become a vegetarian, with the full agreement of my doctor, but sometimes it is hard because fibres irritate my bowels.
    I am increasing antioxidants, probiotics (see dr. Klaper), but are there some foods that can help both my intestine and especially my fight against endometriosis?
    I red a lot about foods that could have caused endometriosis (an excess of red meat), but what should I eat if I already have it?
    Thank you so much, for being so simple in your explanations and for always giving tha source of all the infomation you give!!

      Dear Lorenza,
      I am going to help address the bowel issues you are likely to be having after your intestinal resection; most particularly the resection involving the ileocecal valve. The irritation you are reporting, I would be willing to bet, is related to food moving through your intestines faster, causing you to be prone to a looser stool. It would make sense that fiber would irritate you, because certain types of fibers speed things up even more. There are 2 basic types of fiber: soluble and insoluble. Most foods naturally contain a blend of both. For you, the insoluble fiber would be the type of fiber you would want to avoid in large amounts. Either check the label to determine how much insoluble fiber is in a food relative to the soluble fiber and/or get a small book you can use as a pocket guide, which lists this information. Avoid foods that contain more than 2 grams of insoluble fiber per serving. Soluble fiber, on the other hand, can be helpful as it generally slows digestion, promoting a firmer stool. Also, certain fiber supplements can be helpful such as psyllium and other soluble fibers (pectin, dextrins, etc) (NO insoluble fiber supplements). If they don’t help, you might give a product called “Concentrated Flax Lignans” a try (www.FlaxLignanHealth.com). This is a special product that is very difficult to find anywhere other than online. It is not very expensive and I have found it to be very helpful. As always, run it by your doctor. I hope this helps!

        And don’t forget that you can absolutely follow a vegetarian diet and lifestyle, regardless of your symptoms. It would not be more difficult, and it is the absolute best way of protecting your intestinal health (and the probiotics don’t hurt either!!) and to protect your health in general!!

    I hope dr.Greger will answer to my question about specific nutritional suggestions for patients with endometriosis.
    Megann19 thank you so much for your suggestions, I am learning to choose foods depending on their insoluble fiber amount!

      you might want to ask your question to Dr. McDougall in an email.  He is really good about replying and has experience curing this disease.

      after years of stomach issues, and allergy tests showing I was allergic to dozens of foods. when i started paying attention to my diet, i was able to eliminate the problems. The processed foods made it more difficult to eat the good things. I went vegan, and also paid attention to my pain when I ate grains. If i felt pain the next morning, I knew to eliminate the pasta or the rice. It became easier to eat the veggies without problems. I found that the probiotics unfortunately irritated my stomach and the problems were gone when I cut that out. My rule is to choose foods of the highest amount of nutrition and so that eliminates all items in a box or can. Processes involving chemicals to manufacture the food, will not be listed in the ingredients on the box but can still make it difficult for you to digest it.  Fruits and veggies(non-gmo) have been the best choices for me.

    Dear dr Greger,

    I cured myself from endometriosis with low-fat high-fiber vegan, nonrefined diet, but still I struggle with vitiligo. Is there a dietary treatment for this disease?

    Hello, I have a question about endometriosis. I’m going to have a laparoscopy to remove it but I want to make sure I address the root cause, i.e. the conditions under which it grows to start with. Any advice on diet? What I already found what confusing at best: some say dairy is good, some others absolutely discourage it, same for soy, etc…
    Many thanks for your help.

    Not sure if this is the best location for this question, but I am having trouble finding any links to Pulmonary Fibrosis. My friend’s father was recently diagnosed with Cardio Pulmonary Fibrosis and so I was wondering if you have found any nutritional links or food based treatments for Cardio Pulmonary Fibrosis? Thanks!
