Doctor's Note

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. Be sure to check out all the other videos on antioxidants and don't miss all the videos where we rank foods. And there are 1,449 subjects covered in the rest of my videos–please feel free to explore them!

    Do you know of any research or connections between nutrition & mental illnesses such as Obsessive Compulsive Disorder, Anorexia, or other conditions involving the basal ganglia of the brain??

    • DrDons

      I’m not aware of studies for those disorders… there are studies suggesting that a plant based diet can help improve mood, depression and anxiety. See http://nutritionfacts.org/videos/improving-mood-through-diet/ plus consumption of food additives on children see http://nutritionfacts.org/videos/are-artificial-colors-bad-for-you/. Hopefully more studies will come along showing the benefit of healthy eating on peoples mental well being.

      Avoid gluten. Dr. Mcdougall has claimed that it can cause mental illness.

      • Ed

        What are you talking about? McDougall has never said anything bad about gluten. In fact, he recommends whole wheat as part of your “starch-based” diet, (unless you have Celiac disease like 1% of people). In fact, he’s already done a video about how “gluten-free” is a distraction from our real dietary problems.

    So, now what? Should I be putting beets in my smoothie instead of kale? What about all those other great green leafies, dump them for the new list?

      I usually put beets in my green smoothies (which makes them red). I wouldn’t throw out the greens, but add in the reds, but I’m no doctor.

    • Toxins

      jbwormer, antioxidants are only one aspect of the full nutritional profile of green leafies. There are many nutrients that do not act as antioxidants that are highly benifical to ones health. Keep the greens!

  • jmboss

    This new assay shows that Lettuce has more cellular antioxidant value than Romaine? Something seems very wrong here!

    Sorry to see that Kale doesn’t look to have been included in this study.

    • Bob

      It could be green leaf lettuce…it doesn’t specify iceberg.

  • jmboss

    I suspect the study on cellular antioxidant activity of 25 common fruits will be posted soon. Should be another very informative video.

    Wondering how the antioxidant values of spices would place using this new “real world” assay method.

  • Elvin

    Does this new information have any bearing on cooked vs raw? I recall that according to the video ‘ Best Cooking Method‘ (which by the way is an example of a video with excellent sound, not distorted/too loud /muffled), bell peppers should deffo not be cooked.

    Dr. Greger:
    Where does swiss chard belong on the scale? I grow a lot of it and freeze it so that I can eat it all year. I use it the same way spinach is used. I much prefer it to spinach, and it is easier to grow in my climate. Does it have similar health benefits as spinach?

    This is a very interesting topic. Looking fwd to see the Codex Alimentarius to incorporate this way of measuring A.Ox. into their standard practice. Well spotted Dr Greger. Cheers. fil

    Hi,
    Is it possible to have the complete study (on cellular antioxydant activity) with the graphic. It will be very usefull for my work.

        Hi Dr. Greger,
        I would love to get this study on cellular antioxidants, but they’re charging for the full text! The source isn’t even cited here, I’ve seen it in the #7 DVD:
           
        J Agric Food Chem. 2010 Jun 9;58(11):6621-9.
        Cellular antioxidant activity of common vegetables.

    Can we assume that since beets were so good at penetrating and anti-oxidizing liver cells, that they will do that for all (or even most) cells in the body?

    Or, just like in (http://nutritionfacts.org/video/1-anticancer-vegetable/) will vegetables be more or less effective against different cancer cells?

  • Jack Y.

    Watch your spelling! “Anti-” means against, suggesting one should beware of consuming more veggies. You probable mean “antE-up”.

  • Jack Y.

    I meant “you probably mean….”

    • Ed

      I think he was punning off of “anti-oxidants.”
